Easy Peanut Butter Cookies

I could eat an entire batch of these cookies because they are so delicious and they are kind of healthy because of the peanut butter and oats, right? I will keep telling myself that:)

I love these cookies because I always have the ingredients on hand. You don’t need any special ingredients, but that doesn’t mean the cookies aren’t special, they are VERY special. Every tine I make these cookies they get rave reviews by family and friends. They are just a REALLY good cookie, a classic!

Tips for Making Peanut Butter Oatmeal Cookies

  • Use old fashioned oats, not quick oats for this recipe.
  • Don’t skip the cinnamon, it gives the cookies an extra hint of deliciousness.
  • For this recipe, I don’t use natural peanut butter. JIF or Skippy or a similar brand works best. I use creamy peanut butter, but chunky would be good too.
  • I love the simplicity of these cookies but feel free to add in chocolate chips if you wish.
  • Don’t over bake the cookies. Remove from the oven when the edges are set but the middles are still soft. They will finish baking on the baking sheet. You want them to be soft and chewy.
  • These cookies will keep in an airtight container on the counter for up to 4 days. These cookies also freeze well. Place cooled cookies in a freezer bag or container and freezer for up to one month. They are good frozen or you can thaw them before eating.

The next time you need a cookie fix, make a batch of Peanut Butter Oatmeal Cookies. These simple cookies are always a winner!

  1. ah! These looks so good- my Josh would LOVE them. He is trying to stay away from sweets right now though (lame ;))- I will have to save this recipe for when he comes back to the good side 😉

  2. Oooooh yum! I’m definitely trying these! I’ve been wanting some yummy pb cookies lately, just haven’t found the right recipe to try! Thanks!

  3. Haha, I think I’d call this blog further evidence of your peanut-butter baking adventures — but if you need to get rid of some more evidence you can always mail those delicious morsels to me.

  4. I can personally attest to the fact that these cookies are absolutely delicious. They are perfectly chewy with a great hit of peanut butter flavor, which is not overwhelming in any way.

  5. These sound so yummy! I was going to attempt your New York Chocolate Chip Cookie recipe find.. but I usually only make cookies at the spur of the moment when we all need a quick fix.. the 24 hour refrigeration time caused me to say next time. But these would be perfect for a quick cookie fix!

  6. You are a super good wife, giving up PB when your hubby is home. I’m not sure I could ever do such a thing. We’d have to have a separate PB-friendly room so that I could enjoy my almost daily sandwiches 😛

    the cookies look delicious! I love the idea of adding mini Reese’s!

  7. those are some massive and amazing cookies, maria! i don’t think i’ve ever had peanut butter and oatmeal in the same batch of cookies, but there’s no doubt i’d love it!

  8. Mini peanut butter cups….how have I not found these?!? My boyfriend is going to love these. Thanks for sharing!

  9. My monster cookie has oatmeal and peanut butter… but I have never thought to do JUST an oatmeal peanut butter cookie! Brilliant! It sounds delish and looks even better… GREAT site and GREAT photography!!

    God bless-

  10. Mmmm! I’m SO glad no one at our house is allergic to peanuts or any nuts for that matter, I don’t know how I’d live! 😉
    The cookies look great, love the crackly look.

  11. I can’t wait to make these. I took one home with me, but my husband ate half of it, so I only got one half the next morning. It was fantastic!

  12. I love peanut butter cookies! Doesn’t it ever amaze you just how many varieties of cookies there are? I keep baking and baking, and there’s so many left to try. It’s really a wonderful thing 🙂 These look so good, and they’ve been added to my list!

  13. Did you know when you combine oats wtih peanut butter; the thermodynamic effect of metabolizing it is greater than the calories in the cookie! 🙂
    Someone really tried to tell me that on Sunday!! (and I got the feeling the actually believed it)

  14. You can’t see me but I’m desperately trying to hide the computer screen from my Hubs or he’ll force me to make these cookies for him. HA HA!

  15. Do you use natural peanut butter or the more conventional Jiffy-type peanut butter? I only keep the natural stuff in my house, but I find that some recipes don’t work as well with it.

    1. Veggie Virginia-I didn’t use natural peanut butter in this recipe-I used crunchy Skippy. If you try natural, let me know if it works:)

  16. I made these cookies today. They turned out great, although I did use natural peanut butter. I also excluded the peanut butter cups, it still turned out really good. Thanks for sharing the recipe.

  17. Oooh, oatmeal and pb. I haven’t tried that combo in a cookie. Sounds great! I love using crunchy pb or chopped peanuts in cookies. I agree, it adds a nice texture.

  18. Man, they look good. I like the cracked surface, it looked like dried earth in a desert but in a good way!! I love peanut butter cups but don’t know where to get them in the UK since Woolworths went under.

  19. Yum!! I made a half batch of these yesterday (beating one egg, letting it sit for a second, then measuring out two tbsp to halve it) with chocolate chips and they were so yummy! My husband loved them too.

  20. I feel so sorry for people who don’t like peanut butter. I can’t imagine life without it! Especially when it comes to a delectable cookie like this one… 🙂

  21. I made these cookies with Reese’s Pieces instead of peanut butter cups and they were AMAZING!!! This may be the best peanut butter cookie recipe I’ve ever baked. Thanks so much!!!

  22. very good but mine stayed in little balls. i bake all of the time (love your recipes!! you are a fabulous baker!) and i’m not sure what i did wrong? Also, Caleb is adorable!! I have a 10 month old son so I always love hearing what Caleb’s up to!

  23. So I just stumbled across your wonderful site after looking for a unique cookie recipe. I never had these combonations and I was willing to try since I was in a baking mood. Let me tell you! These are excellent! My 2nd batch is in the oven as we speak. My fiance has eaten half of the first batch already. I will definetely spread the word about your blog and your recipes.

    Next up: Tofu Tostadas. Very excited about those! =]

  24. Great cookies ! I just made the batter without adding the cups and they completely satisfied my peanut butter cookie craving nicely!

  25. Just made these and they are soooo yummy! I used my own home-milled whole wheat flour and –wow! Super soft yet chewy! I wonder if substituting honey for the white sugar would work? I love p.b., oatmeal and honey combos!

  26. Not sure what I did.  Doubled the recipe and the dough was extremely crumbly.  I added 2 more eggs and they turned out great.  (I’m a pretty experienced baker, so not really sure what happened.)

  27. I would very much like to try these, but I am a little confused.  Some of the comments talk about adding peanut butter cups or peanut butter chips, but I don’t see a mention of these ingredient in the recipe.  If I were to make the additions, how much do you recommend?  If I am overlooking this information, I apologize.  Thank you!

    1. These were absolutely delicious!  I added a heaping 1/2 cup of peanut butter chips for extra yum.  What wonderful cookie recipes you have!  Thank you.

  28. I just finished making these and they are very tasty. My only problem is they didn’t spread out very much and I don’t know why. I mixed some with white chocolate chips, some with chocolate chips, and some with honey roasted peanuts. All delicious!

    1. Hmmm, maybe because all of the extras??? Or too much flour??? Or your butter was too cold??? You can always slightly press down on the cookies with the palm of your hand before baking if you are worried they won’t spread. I have never had a problem with this recipe though.

  29. I just made these and they are delicious! Had to cook them a little longer (about 14 min per batch) but that’s probably our wonky oven. Fantastic!

  30. These cookies were PERFECT. I was looking for something I could make using ingredients I had on hand. Mine were not as flat as the picture, they were fluffier but still baked nicely in the center. I added double the cinnamon. Will definitely make this again and maybe add in chocolate chips next time.

  31. Absolutely Delicious! My family gobbled them up. I added choc chips to half of them and they were perfect.
    Thank you!

  32. Wow these cookies are so delicious!! I haven’t made cookies in forever and found these through a search for peanut butter oatmeal.  Really amazing! I also put some chocolate  toffee pieces in them and made for some nice texture. Thank  you so much!

  33. Excellent recipe. The cookies come out light and airy with a perfect amount of crunch. Will DEFINITELY make again!!

  34. Great basic recipe. Due to food allergies I used sunflower butter and gluten free oats and flour. Needed to freeze cookie balls for 10 minutes. The second batch I added white chips and made half with chopped peanuts. Next batch is macadamia nuts and white chocolate. Thank you for a fabulous cookie base.

  35. This is an excellent recipe! Makes Awesome Cookies!
    I add 6 oz. of chocolate chips per batch which satisfies both the peanut butter and chocolate lover in me.

  36. Just made these and added chocolate chips and used crunchy peanut butter. These are the best peanut butter oatmeal chocolate chip cookie  of all time. Wonderful chewy texture, not too sweet, look exactly like the cookies in the  picture  and absolutely delicious. Thanks so much for this fabulous recipe. It’s a keeper and I’ll be making these over and over! 

  37. Do you have the nutritional values for these cookies including grams of sugar and protein? Could I replace the all purpose flour for the almond flour?

  38. Came out perfect. I got out my stand mixer and made a double batch. I used partly whole wheat flour, sub half the butter for shortening and added some chocolate chips. I will make this again for an everyday or traveling cookie.

  39. I wanted to bake something quick and easy last night and this recipe was perfect for that! I used 1/2 cup of nut flour ( almonds, coconuts, pecans and walnuts) instead of all purpose flour. I also added chocolate chips to 1/2 the batch. It all came out amazing!

    1. Omg…….I can’t stop…..These are sooooo delicious…….thank you for ANOTHER great recipe! Been following you for years! 

  40. I’ve been using this for lactation and I make them at least twice a week. My husband tried one out of curiosity and requests them! Soooo good!

  41. I just made these cookies and they are excellent! They come out crispy on the outside and chewy on the inside. I baked a half batch 5 minutes longer and they are super crispy all over just like I like them. Definitely making these again!

  42. These cookies were EXCELLENT!!! I must have made them very small because my batch yielded 45! Since it’s Christmas, I decorated them with green and red jimmies. This will become a new tradition!

  43. This is amazing, quick and easy recipe I have no peanut butter available, so I made a twist on the recipes, I put apples instead. Perfect!

  44. Made these today & quite pleased My grandsons are tiring of their usual breakfast so though I’d tries come healthier cookies. I added cooked, crumbled bacon & diced cranberries. I also cut the sugars in half & still very sweet. Only thing i notices is mine did not spread like the picture – but they are a hit! any other ideas to turn these into a breakfat cookie?

  45. I used the quick cook oats because that is all I had. I also chilled the dough before making balls and putting on the trays. I always chill to re constitute the butter. Baking took 13 minutes, because of the chilling I expect. Cookies came out nice. Deb gives it a 4/5.

  46. Those look absolutely delicious. I’m not a chocolate (in cooking) fan, but I’m a peanut butter addict, always have been. So can you tell me what you mean by ‘natural peanut butter’ that you don’t use? I don’t know what that is and I don’t know if the stuff I’d be using would work.
    Thank you

  47. Really tasty and simple to make. I made a half recipe and added a handful of golden raisins. Can’t afford to make the full amount because then I’ll eat them all. You know, too much of a GOOD thing.

    I made them dairy & egg free by using Nuttelex instead of butter and “no-egg replacer” instead of the egg.
    SO GOOOOOODDD. Can’t stop won’t stop eating them.

  49. We just made these again yesterday and they are indeed the best cookie ever. We have made these several times since you originally posted the recipe and they have been declared ‘the perfect cookie’. We have added ginger and cut back on the cinnamon. It can be fun to play around with a recipe after it has been mastered – of course, you know that!

    In any case, many thanks for an absolutely splendid recipe.

  50. I used natural peanut butter with great results! The cookies are chewy and soft, although they did not spread as much as the pictures. I prepped the dough the night before, scooped it into balls and then refrigerated it overnight. The next day I used a glass to flatten the cookies slightly right before baking. I liked the addition of cinnamon, although I will try 1/4 tsp next time! Thanks for another great cookie recipe!

  51. I’ve tried baking quite a few different recipes to test which one my husband and i both agreed to be the best and this recipe by far hands down our favorite of all! Thank you!

  52. Dude! Game changer!!! I love these. I added dark chocolate morsels to the second half and it was the best decision I have made all day. Thank you

  53. Dude! Game changer!!! I love these. I added dark chocolate morsels to the second half and it was the best decision I have made all day. Thank you

  54. I substituted ground oats for the flour due to a wheat allergy and these are great cookies. Wonderful flavor with the cinnamon.

  55. Tried these today and LOVE them! My batch came out just as pictured and taste amazing.
    I use a gas oven and followed the recipe exactly including letting the cookies rest on the pans until they came off clean.
    Fantastic cookie outside light crisp with the even texture of moist chewy yumminess throughout the entire cookie. Thank you so much for this recipe I will make these again!

  56. These cookies are fabulous, I had to repeat them several times. I did however tweak the recipe a bit: whole spelt flour instead of all-purpose, flavorless coconut oil instead of butter (just because the butter was hard and I would have needed to wait for it to soften, but it works great!), and just some xylitol instead of so much sugar (we went off sugar and use very little sweeteners at all). They come out really yummy and almost guilt-free!

  57. Added 1/4 c chia seeds, 4oz butterscotch chips, substituted stevia for white sugar, added walnuts. Yummy!

  58. I just made the Peanut Butter Oatmeal cookies today. I followed the recipe exactly and they turned out perfect and tasty! I will make this again.

  59. I made these cookies last night and followed the recipe exactly. They were amazing! My husband and son nearly ate them all!

  60. I need these to be firm and crunchy. I want to fill them with marshmallow whip and dip in chocolate. What do I need to do different to get them cruncy?

  61. I used GF flour 1/3 cup turbinado sugar and raisins to make them healthy. They were still plenty sweet because of the sugar in the raisins and the PB. Yummy! Thank you!

  62. These are fantastic. I use organic whole wheat pastry flour for an even healthier cookie treat. Everyone loves them. Just made them for the fourth time. Thanks.
