It’s zucchini season and that makes me giddy! I LOVE zucchini! I think it is probably my favorite vegetable. Please don’t tell the other vegetables, I don’t want to hurt their feelings:) I go zucchini crazy when it is in season and make everything with zucchini. I put it in pancakes, salads, salsacookies, cupcakes, brownies, and I even make noodles and nachos! I can’t get enough!

For the Cake:

For the Brown Butter Streusel Topping:

For the Glaze:


  • Preheat the oven to 350 degrees F. Grease a 9×13 pan and set aside.
  • In a small saucepan, brown the butter for the cake. Melt the butter over medium-low heat and continue to cook, swirling occasionally, until butter turns golden brown and has a nutty aroma. Pour butter into a small bowl and set aside to cool to room temperature.
  • In a large bowl, whisk together flour, brown sugar, baking soda, salt, cinnamon, and nutmeg. Set aside.
  • In a small bowl, whisk together browned butter, Greek yogurt or sour cream, eggs, and vanilla extract.
  • Pour liquid ingredients over dry ingredients and stir. The batter will be very thick and somewhat dry. Add the shredded zucchini and stir until cake is combined and moistened. Again, it will be very thick. Pour cake batter into prepared pan.
  • To make the streusel topping, brown the butter. Melt the butter over medium-low heat and continue to cook, swirling occasionally, until butter turns golden brown and has a nutty aroma. Pour butter into a small bowl and set aside to cool to room temperature. In a small bowl, combined browned butter, brown sugar, flour, and cinnamon. Mix together until crumbly. Sprinkle topping evenly over cake.
  • Bake for 30-35 minutes, or until a toothpick inserted in the center comes out clean and the cake is light golden brown. Let the cake cool on a wire cooling rack.
  • While the cake is cooling, make the glaze. In a small bowl, whisk together the powdered sugar, milk, vanilla, and cinnamon. Whisk until smooth and drizzle over cooled cake. Cut into squares and serve.


The cake will keep covered on the counter for 2-3 days.

    I never leave reviews on recipes no matter how good or bad they are but this is seriously amazing.. SO good! For someone who doesn’t bake (or cook) much overall it was pretty easy although it looks scary due to the ingredients and such.. So amazing. Go make it. Right now. I might eat the entire pan tonight.

    Brown butter makes everything better. I made this the other week and it was delicious. I had a bit of difficulty getting the zucchini to mix in with the rest of the dough which had become a pretty coherent mass on its own, but ended up getting there. The brown butter in the streusel topping was also a nice touch. Thanks for the recipe!

  3. 5 stars
    Omg this came out soooooo good! It’s moist, the brown butter flavor is fantastic, and the icing I have to stop myself from eating the whole thing!

    My daughter and I made this coffee cake today and it was wonderful!!  Allowing the butter to brown, gave the cake great flavor!! 

  5. 4 stars
    Apparently it is now my responsibility to make this for my family. It’s delicious! The 2nd time I made it I used an insulated cake pan. The cake was shorter, more dense, and the zucchini did not get as soft as it did the first time I made it. I’ll stick with the glass pan. How about using frozen shredded zucchini? How much? Do you drain it, as frozen is a lot more watery than fresh.

    This is SO GOOD! As the author states, the batter will be very thick, but after adding the zucchini it will moisten up more. Because of the batter being thicker than usual you will have to spread it out to cover the 13 x 9 pan. Again, this cake is awesome with a cup of coffee or a glass of milk!

      Excellent recipe. I added chopped walnuts to the streusel. Also if you mix the zucchini in with the wet ingredients it all incorporates very well with the dry. No need to wrestle with it on the end ,it mixes together very easy.

    This cake is awesome, moist , sweet  and very 
     Delicious . The cake is easy to make  but it doesn’t last long in my house.

    I think the key to this recipe is patience. Go slowly as you brown the butter, thoroughly mix the wet and dry ingredients (it takes a little while), gently fold in the zucchini. I made muffins that smelled heavenly, looked beautiful, and disappeared in an instant. Too delicious for words!

    Oh my goodness!! So good!!! One of my daughters helped make it. First time we had ever done anything with brown butter. I couldn’t even wait for it to cool! Inhaled my piece with a glass of milk! Yummy!!!

    I Love, love, love this recipe! I find myself with a freezer fill of pumpkin purée from my garden and am wondering about adding pumpkin to it- how would you adjust the flour ratios with pumpkin purée addition?

  11. Hi. I can’t see any coffee in the instructions or ingredients list. Please can you tell me how to turn the recipe into a coffee cake.

    1. There actually isn’t any coffee in coffee cake, they just call it that because people typically drink it with coffee:)

  12. 5 stars
    This is sooo GOOD! Like the best ever. I would eat it everyday. My husband was like, WOW this is good cake! Everyone should make this!

    1. I haven’t and I wouldn’t recommend it. Almond flour is very different. You can use gluten-free all-purpose flour. I like Cup4Cup.

    Made this today, it’s so good! I don’t often make coffee cakes, but the picture looked so good, that I had to try it. Definitely will be making again. Even my husband loved it.

    Wow! Loved this coffee cake! This recipe is definitely on my keeper list. I had some cinnamon chips in the cupboard so I cut back a bit on the cinnamon in the recipe and added some cinnamon chips instead. And I added a few drops of coffee flavored oil to the glaze, just because I could. The results were an absolutely delicious coffee cake.

    So moist and light…I wouldn’t have believed it for a zucchini cake. And they are right… the browned butter makes all the difference. Don’t skip that step. I felt better eating it because it was made with lowfat Greek yogurt (extra protein). Absolutely delicious.

    I have been trying so many zucchini (I use cucuzza instead) recipes lately. This one TOPS all the cake recipes! Love the sophisticated subtle flavor of the browned butter! Si yu’os ma’ase’ for sharing!

    This recipe, as written, is a keeper! Absolutely delicious. Moist, not too sweet. Not overly dense like some zucchini bread/cakes. Love the crumb topping, combines zucchini bread and coffee cake perfectly. Was a little hesitant to try my culinary skills with needing to brown the butter, but took it to an event and it was gone quickly. Making my second batch in two days. For those who dislike zucchini, give it a very fine shred and you’ll never known it’s in the recipe. Thank you for sharing.

    This is definitely a keeper recipe! The zucchini are now coming in abundance! I made no changes to the recipe. It is delish!!!

    I just made this, but added chopped pecans to the streusel topping. SO delicious!! This recipe is a keeper. I have lots of zucchini from my garden, so I will be making this over and over again.

    Thank you, Maria! Great easy to follow recipe! I made 3 of these, kept one(it’s already gone) and gave 2 away to neighbors, they LOVED it! DELICIOUS!

  21. It’s in the oven !!! Added 1 diced apple and some chopped walnuts to the batter. When I made the streusel, added chopped walnuts to that too, along with apple pie spice with the cinnamon to tie into the apples in the cake .

  22. 5 stars
    This really is amazingly wonderful! I even skipped browning the butter. My daughter said it’s the best thing I ever made 🙂

  23. 5 stars
    Best cake I’ve ever made. I made it for friends coming over and we were all so impressed by it. Great recipe!

  24. I made this today; the flavor was fantastic but mine was super dense. My kids loved it but my husband and I could tell something was off. I am trying to figure out what I did wrong…I think I got impatient and added the brown butter before it was completely cooled down to room temp. Would that possibly impact the baking soda/powder and prevent rising? Thanks!

  25. 5 stars
    Absolutely delicious. I have never browned butter before – and still not sure I did it correctly, but the end result was excellent. Like someone recommended – I added the zucchini with the wet ingredients, and then the dry. I skipped the icing. Also wondering why we couldn’t brown the butter for both parts of the recipe at the same time – and divide it as needed?

    1. Glad you liked the cake. Yes, you can brown it all together, just make sure you divide it equally:)

  26. 5 stars
    This is a family favorite. My kids are always excited when they know this is coming out of the overnight! I have four boys and three are teens so you can imagine how often I am making this for them and their friends!
