lemon blueberry bars

It is a hot week in Utah. I try to not turn on the oven, but I always cave in. My love for baking is far more important than the heat. I try to do my baking first thing in the morning so it isn’t too too hot. This week I made Lemon Blueberry Bars. The house might have gotten a little warm, but these easy lemon bars were well worth it.

These Lemon Blueberry Bars are a spin off of my Lemon Raspberry Bars. I mixed things up a bit by adding blueberries. If I had to pick a favorite bar, I don’t think I could. I love them both. I think I love whatever bar I am eating at the time-blueberry or raspberry:)

These bars have a thick graham cracker crust and are topped with a luscious lemon blueberry filling. The filling is silky, smooth, and refreshing. The fresh, plump blueberries add a juicy pop of sweetness to the tart lemon filling. Serve the bars chilled for a cool, summery treat.

Last night, after it cooled down, I cut two lemon squares and took them out on the patio for us to enjoy. It was the perfect summer dessert. If it is hot where you are and you don’t want to turn on the oven, I understand, but trust me these Lemon Blueberry Bars are worth a little heat. And the total baking time is only 25 minutes-you can tough it out:)

For the crust:

For the filling:

  • 2 large egg yolks
  • 14 ounces sweetened condensed milk
  • 1/2 cup fresh lemon juice
  • 1 teaspoon lemon zest
  • 1 cup fresh blueberries


  • Preheat the oven to 350 degrees F. Spray an 8×8 inch baking dish with cooking spray. Set aside.
  • In a medium bowl, combine the graham cracker crumbs, melted butter, sugar, and lemon zest. Stir until graham cracker crumbs are moist. Press crumbs firmly into prepared pan. Bake the graham cracker crust for 10 minutes. Remove from oven and allow to cool to room temperature.
  • To make the filling, combine the egg yolks and condensed milk in a medium bowl. Stir in the lemon juice and lemon zest. Stir until mixture is smooth and begins to slightly thicken.
  • Gently fold in the blueberries. Pour the lemon blueberry filling evenly over the graham cracker crust. Bake for 15 to 17 minutes, or until just set.
  • Cool to room temperature, then chill in the refrigerator for at least one hour before serving. Cut into bars and serve.


Bars will keep in the refrigerator for 3-4 days.

  1. I’ve been following your blog for some time and love your recipes:)

    I just had to comment because I JUST had something very similar to this yesterday at lunch and have since been googling like crazy trying to find a recipe to duplicate it and by complete cooincidence you’ve gone and posted this today! So THANK YOU:)

    I can’t wait to make it!

  2. Those bars must be divine! Anything that contains, lemon, blueberries and condensed milk is fabulous.



  3. Omg these sound soooooo good!

    “thick graham cracker crust and are topped with a luscious lemon blueberry filling. ”

    I love graham cracker crusts and the smoothness of the lemon + the bloobs. Nice.Work.


  4. yep, i just died and woke up in heaven. lemon bars are my favorite, but add some blueberries and it just doesn’t get any better!

  5. I have a weak spot for anything with lemon and the addition of blueberries is a wonderful idea! The pictures are so inviting – can’t wait to try them!

  6. I LOVE anything with lemon and blueberries are so ripe this season!!! I’ve been finding such great crates at the farmer’s market. This recipe is on my list to make! YuM!! Check out my homemade Nutella-peanut butter brownies 🙂

  7. lemon + blueberries is one of our favorite combos! These look perfect for the hot summer nights we’ve been having lately, too.

  8. Lemon and blueberry is such an awesome combination! Yum! These actually reminded me that I have extra lemons in the fridge this week that should get used up. Awesome!

  9. You’re absolutely right – definitely worth using the oven in the heat if you can cool of with these delicious bars 🙂

  10. These are so so worth 25 minutes of heat. Heck, they’re worth an entire day’s worth of heat, if not more! I love the sound of that filling. I’ve done a lemon blueberry cheesecake bar before, but this filling looks like it could top those!

  11. I am without doubt going to give these a pop sometime very soon 🙂 they really do sound totally perfect for summer 🙂

  12. These look delicious! And I have some blueberries I need to use up so this is perfect! Thanks for sharing!

  13. Love this flavor combination. I’m w/ you heat or not baking happens-it’s much more important. 🙂

  14. These look wonderful, Maria! I am melting in this heat, but can’t resist baking some goodies either.

  15. My wife and me made lemon bars before but this right here adds a new dimension and sounds like I would love it especially when I love blueberries. Thanks for sharing this recipe 🙂

  16. These look and sound amazing. I’ve been on a mega fresh lemon kick so I think I can handle heating up my kitchen for half an hour for this dessert. 🙂

  17. looks like we’re both on a lemon blueberry kick today…agree that it’s well worth turning the oven on! These are gorgeous!

  18. These look so delicious! I bought a ton of blueberries last week on a deal, but there’s no way we could eat them all before they went bad. So I froze some fresh blueberries. Would those not work in these?

  19. Lemon bars are so perfect for a summer dessert. Try to stay cool girl! When we bought our ID house, my husband insisted in installing central heat & air. What do you expect from a Texan though-we are just used to those blazing hot summers! I think we were the only house on the block w/ AC!

  20. I can tell that I would love the texture in these, custardy with a burst of blueberry in each bite.

  21. OMG, do you read minds? I was just thinking how delicious a lemon bar would be with the addition of blueberries and this bar sounds perfect! I also just bought some organic graham crackers that were on clearance (and rather broken, sadly) and was trying to figure out what dessert I could make with graham cracker crumbs! Blueberry and lemon is my favorite combination, hands down, so this is DEFINITELY going on my “bake VERY soon” list! THANKS!

    ps- I just looked at your raspberry bar post that you linked to; did you notice that you posted that bar recipe almost EXACTLY a year ago? June 28, 2010! What a coincidence!

  22. Do you think these bars would freeze well? We’re leaving on a boat trip soon and I could make them ahead of time…

    1. I haven’t tried freezing them. I am not sure how the filling would do once defrosted. Hmmm. I need to try it. If you try it, let me know!

  23. these look divine! I just tried creating a similar type of tart (not a bar, but so similar!) and it was delicious! I imagine this one will be equally tasty! 🙂

  24. Hi Maria, These bars look wonderful. I am doing a wedding dessert bar in November and lemon bars are on the list. I was going to do a recipe with white chocolate chips but these bars look like a good contender. I pinned them for reference.

  25. How fun is this? I bet you could do raspberries AND blueberries or blueberries and strawberries and make it a red white (ish) and blue dessert for the 4th!

  26. Ooo, blueberries and lemon are awesome together. Although so are raspberries and lemon, I can see why that would be a tough choice.

  27. Just made these…oh my god SO GOOD!! It was honestly heaven in bar form. Could be a little less sweet but you can’t really change that since it uses sweetened condensed milk. I added a scant 1/2 tsp kosher salt to the crust to get a lil sweet & salty action. Yum!

  28. I was just looking for a recipe cause I have a lemon tree in my backyard- this will be perfect 😉 Yummers!

  29. It is crazy hot in Phoenix, but like you, I always cave and turn on the oven in the early morning. These bars definitely look worth it! Stay cool in Utah 🙂

  30. What a perfect treat on a hot summer day! I love blueberries and lemon together too. Yum!

  31. They look gorgeous! I’ve just bought some measuring cups so I can try out some of your recipes!

  32. How delicious – can’t wait to try these with the kids – and I think we will add a whole bunch of summer fruit to the mix – apricots, peaches, strawberries, blueberries and or raspberries – I bet a tropical mango/pineapple thing would work well too… yummy!

  33. This looks AMAZING! I can’t wait to try making these. Thank you for the beautiful pictures and recipe. I shared this post on my Friday Features today. I hope many more readers get to share in the deliciousness of your recipes! Have a wonderful weekend!

  34. there’s something that blueberries do to lemons or vice versa that simply enhances both. lovely bars, maria!

  35. This reminds me so much of a dessert I had on vacation years ago and have always wanted to try and recreate but haven’t been able to. I will have to give this a try over the weekend!

  36. These are right up my alley! I’m going to make them to bring to a party on the 4th. I don’t know if 8×8 will make enough…do you think I could do it in a 13×9 pan and double the recipe? Will that affect the cooking time?

    1. Yes, you can double the recipe. They will probably have to bake for longer though. I would bake the crust for 10 minutes still and then just watch when you bake them the second time. Set the timer for 15 minutes, if they are not set. Add 5 minutes and check again. Enjoy!

  37. Oh how funny….I think I saw these on FoodGawker AND Tastespotting…I should have known they were your pretty pictures!

    These sounds just perfect for hot weather!

  38. Yes, I made these and they are currently in the oven. I’ve tasted the filing and it’s soooooooooooooooooooooo heavenly! I’m really excited to cut into these tomorrow for the 4th of July!

    I’ll let you know how they turn out.

    Btw-These were SUPER easy to make, the hardest thing on the list was making the graham cracker crumb crust. I was smashing them by a spoon until I realized I could just crush them in the blender. Duh!

    Anyways…this was super easy and freaking delicious. Thanks:)

  39. These bars look amazing! I love the addition of the blueberries. I have a whole bunch of blueberries in my fridge right now. I think I know what I am going to make with them! 😉

  40. I looooove lemon bars, and they are so perfect for the summertime! Blueberries can only make them better, I imagine 🙂

  41. There is nothing better than lemon and blueberry together! We’re hosting an online seasonal potluck and July is blueberry month. If you’d like to link your recipe, we’d love to have you! http://bit.ly/eLlgG2

  42. I made these over the 4th of July weekend and they were absolutely delicious. I used fat free sweetened condensed milk and thawed some frozen blue berries. Instead of stirring them into the topping mixture – I poured the topping over the crust and gently dropped the blue berries right on top. It worked out perfectly – they didn’t bleed juice all over and it tasted sublime! Yum!

    Thanks so much for the recipe…I’ll be making this every year from now on!

  43. Ooh, I want these. And to Charissa, who has as lemon tree in her back yard—totally jealous.

  44. Hello there, You have performed a fantastic job. I’ll definitely digg it and personally recommend to my friends. I am sure they will be benefited from this website.

  45. Hi looks delicious, I wanna make them now but I dont have blueberries at home. Can I use dried cranberrys or fresh strawberries?

  46. Made these and they are AWESOME!! They taste kind of like cheesecake. Perfect for a summer barbeque!

  47. I’ve made these twice now, first with Blueberries and today with Raspberries!! Now sure which one I like more but they are both out of this world delicious!!

  48. Super easy, super delicious. This is now my favorite summer dessert. Made it last week, making it twice this week! Thanks so much!

  49. I have made this recipe several times and it has become of my favorite things to make!

  50. I don’t like graham cracker crusts – think I’ll make it with a shortbread crust which I think will taste as good. Have you tried shortbread crusts?

  51. Made this last night for a dinner party and it was delicious and a huge hit! I had to double the recipe though 🙂

  52. I’d like to make these ahead of time for a party. Do you know yet if they can be frozen ahead of time?

  53. These look wonderful! My sweetie can’t eat eggs or sugar; will the filling work with that powdered potato-starch-based egg substitute that you mix with water, before adding other ingredients? And how much stevia would one use to replace the sugar in the crust? Thank you!

  54. Now THESE are amazing! I used splenda in rhe graham crust and you couldn’t tell at all! Taste just like cheesecake! Everyone in the house loved them! Do you happen to know what the calorie count is and fat??

  55. I made these for a 4th of July party and everyone loved them! A great summer bar recipe, sweet and tangy. They’re delicious!

  56. Made these for the office and they were a HUGE success! Such a simple, yet richly delivered treat! Yummy yummy, Thank you Two Peas and Their Pod!! 🙂

  57. I wanted to know if I can substitute applesauce for the egg yolks since I am Vegan. I also wanted to ask what can I substitute for the sweetened condensed milk?


  58. these look absolutely delicious… However can you tell me what the alternative to graham crackers is in the uk. Thank you so much .

  59. We just made this recipe and it tastes gorgeous! We made it with dry cranberries instead of blueberries and it was tasteful! Next time though, we won’t add the extra sugar in the crust..it is sweet by its own!

  60. Looks gorgeous and of course greetings from Arundel, Sussex!  What are graham cookies?  We dont have anything under that name marketed here.  Are they perhaps ‘gingernut’ biscuits (hard biccys that we eat here)

  61. I’m a lazy cook, I’ll tell you right off. So saying that I used a boughten graham cracker crust and 1 cup of thawed frozen blueberries. But your recipe is YUMMY! Thanks for sharing. My husband loves lemon things and he loves blueberries so he was ‘happy’ tonight! 

  62. I made these today for my visiting in laws. Absolutely delish! A perfect afternoon treat with coffee and tea. Thanks for helping me impress my MIL!

  63. So glad you said they were a knock off from Raspberry! I prefer Raspberries over blueberries when adding them to a cooked recipe!

  64. How about switching condensed milk with coconut milk (that’s all I have!!!) – would that work you think ?

  65. Hello!
    I tried to make these today because I love lemon bars and who doesn’t love blueberries. Unfortunately mine did not set up much in the oven and I baked for an extra 15 minutes. Anyone else have this problem? Is there something missing in the filling part of the recipe?

  66. Is there any way to make this diabetic friendly? I could reduce the amount of granulated sugar but the condensed milk? ✌

  67. 5 stars
    Do you happen to know whether it is possible to use cookie cutters on the final product to make it into different shapes rather than bar-form? Thank you!

  68. I have made these many times and I love them. But for some reason the past 2 times I have made them, they have come out with a powder like texture. Can anyone explain why please.

  69. Delicious- will definitely make again as company thoroughly enjoyed!!
    Can this recipe be frozen?
    Thanks so much!

    These are absolutely, positively, the most DELICIOUS bars I have ever made. I followed the recipe to a tee, and they turned out amazing. I’ll blame it on being 38 weeks pregnant and my love of lemons, but I ate 4 as soon as they were ready. I am so excited to make these with raspberries! So refreshingly good and easy to make! Thank you, thank you, thank you!!!!!

  71. 5 stars
    Love this recipe! We picked fresh berries this summer and I made one batch with blueberries and one with raspberries. I can’t tell which one I liked better!

  72. 5 stars
    Bursting with lemon flavor. One of my most favorite desserts I’ve ever made. Perfect for spring/summer.

    Made this for a party yesterday and it was a huge hit!!! They were so good. Thank you for the recipe.

  74. 5 stars
    I have been making this recipe for a while now. I used to bring this to any occasion I attend to before the Covid19 happen and it was always a hit. And I’m making it again for my 9th wedding anniversary as my husband and kiddos request.
    Thank you for sharing your wonderful recipes. I’ve been following your blog and on Facebook and been using your recipes for food and dessert.

  75. 5 stars
    Made this for a gathering yesterday. It was so hot yesterday so I wanted something that didn’t require a lot of baking and this was perfect. It got rave reviews. A friend even said it was his favorite thing I’ve ever made! Thanks for the recipe!

  76. My daughter is on a diet where she can have whatever but has nutritional guidelines that she must adhere t. Do you happen to know the NV of this?

  77. Made these for last night’s dessert. It was 95 degrees here yesterday, and this is the perfect summertime dessert! We love the lemon and blueberry combo. Can’t wait to try with raspberries. One family member suggested another option would be making with orange zest and pineapple instead of the lemon and blueberries! Thanks for such an easy and delicious recipe! We finished the leftovers tonight!

  78. 5 stars
    I made these for friends at a get-together like 2 years ago and they were such a hit. Any time we have an event they beg me to make them. Now I always make 2-3 batches because they go so fast.

    Easy to make. Absolutely delicious. The only problem is trying not to eat the whole batch yourself!

    10/10 recommend.

  79. Hi Maria, what is the difference between this Lemon Blueberry Bar and your Lemon Bar? Can I use the Lemon Bar recipe and add some blueberries to it? Many thanks for your help.

    1. They are actually very different. This recipe has sweetened condensed milk and a graham cracker crust. I haven’t tried my traditional lemon bars with blueberries.

  80. It looks like you used some sort of paper under your graham cracker crust in the photo. Could you explain? Also, If I double the recipe in a 9×13 pan, will I need to change the baking time? I would think they might be thicker. Do you suggest a glass pan or metal pan? (I am not a baker and hence appreciate your best advice!) Thank you! These look delicious!

  81. 5 stars
    I made this on Monday, and am making it again today, Saturday. We can’t get enough and so quick and easy to make. It’s delicious

  82. i just made this and the crust is stuck to the pan; i thought there was parchment paper on the baking sheet like your photo shows but your recipe does not mention it..why did that happen and how do i correct it?

    1. Its 2023 and it happened again LOL however this time the crust is very crumbly:(

  83. These bars are the best! Very easy to make and so delicious! I’m making it tonight for the third time this month!

  84. Made these for the first time, and they were delicious. However, the custard did not set even when I doubled the baking time. Is the baking temperature correct? It was mushy and couldn’t be cut into bars. We ate it anyway because it was so tasty!

    1. Yes, but maybe your oven is different? Maybe bake a little longer next time. Glad you still enjoyed them.
