Peanut Butter Honey Buttermilk Cake with Chocolate-Peanut Butter Streusel

A few weeks ago I went to Big Potluck and was assigned to bring a cake to share. It was, after all, a potluck.

This was my contribution.

I was stumped about what kind of cake to make. I thought and thought about it. And thought some more. I read recipes on blogs, Pinterest, Foodgawker, and more. Cooking for an event where fellow bloggers, cookbook authors, and a Food Network TV show host may eat it was adding just a wee bit of pressure.

I opted to go with peanut butter and chocolate. Shocking, I know. Since my cookbook is about peanut butter, I thought that I may as well represent. The cake isn’t in my book, but I wish it was.

It’s a fast and easy cake to make, and only one bowl is dirtied. There’s no long creaming of ingredients, or separating eggs, or anything fussy or complicated.

The batter comes together in 5 minutes, it bakes for about 25 minutes, so it’s literally a 30 minute cake.

There’s no granulated or brown sugar in the cake layer, and instead it’s sweetened with honey. I love honey and had never made a cake exclusively sweetened with it until now.

It’s a more delicate and mellow sweetness, rendering the cake just sweet enough, and it won’t leave you with a toothache.

The other bonus to this cake is that it doesn’t need to be frosted because of the streusel. I love eating frosting, but I don’t like the act of frosting cakes or cupcakes. I prefer glazes, drizzles, or ganaches that can be poured over without much fuss. Even better is streusel.

It was a miracle I didn’t pick it all off, but wanted to.

The photo shoot was so hard because I wanted to tear into the cake so badly, but refrained. It was worth the wait when I was finally able to eat a piece of my own cake at the potluck.

Sadly, I forgot to take a picture of my own cake. I was too busy with wine.

But Amanda took this picture. Thanks, Amanda!

The cake itself is soft, tender, and springy. It loosely reminds me a yellow cake mix cake, but better. Anything spiked with buttermilk, honey, and peanut butter is destined to be moist and bouncy.

It’s surprisingly lighter than you’d imagine given the list of ingredients. Buttermilk has a way of moisturizing and tenderizing anything it touches, while also keeping things lighter and fluffier.

The streusel topping with brown sugar, peanut butter, and chocolate chips is so tempting. I wanted to pluck those golden crumbs right off the cake and into my mouth.

Chocolate and peanut butter are always a match made in heaven, and those big nuggets add a boost of bold peanut butter and chocolate flavor.

It’s my idea of a good cake and a good time, for sure.

Peanut Butter Honey Buttermilk Cake with Chocolate-Peanut Butter Streusel - Soft, fluffy peanut butter cake with big streusel pieces make this easy cake the first to disappear at parties!

The cake is tender, moist, and buttery, thanks to the buttermilk, butter, and peanut butter. There’s no sugar in the cake batter and is instead lightly sweetened with honey. The streusel layer is chock full of peanut butter flavor and is bursting with chocolate chips. Best of all, the cake is made in one bowl in 5 minutes. No one has to know how fast and easy it is to make.


For the Cake

2 cups all-purpose flour

1 1/2 teaspoons baking powder

3/4 teaspoon baking soda

pinch salt, optional and to taste

2 large eggs

3/4 cup honey

3/4 cup buttermilk

1/2 cup unsalted butter (1 stick), softened

1/3 cup creamy peanut butter

1 tablespoon vanilla extract

For the Streusel

3/4 cup light brown sugar, packed

1/2 cup creamy peanut butter

2 tablespoons all-purpose flour

1 cup semi-sweet chocolate chips


  1. For the Cake – Preheat oven to 350F. Line a 9-by-13-inch baking pan with aluminum foil and spray with cooking spray, or grease and flour the pan; set aside.
  2. In a large mixing bowl, whisk together flour, baking powder, baking soda, and optional salt.
  3. Add the eggs, honey, buttermilk, butter, 1/3 cup peanut butter, vanilla, and beat with an electric mixer on medium-low for about 1 minute. Stop, scrape down the sides and bottom of the bowl, and beat for 1 more minute.
  4. Turn batter out into prepared pan; set aside.
  5. For the Streusel – In the same mixing bowl (no need to wash it), combine brown sugar, 1/2 cup peanut butter, flour, and stir with a spoon until sandy pebbles form.
  6. Stir in the chocolate chips.
  7. Sprinkle streusel evenly over cake batter.
  8. Bake for about 25 minutes, or until a toothpick inserted in the center comes out clean, or with a few moist crumbs, but no batter. Allow cake to cool completely in pan on a wire rack. Lift cake out using foil overhang, slice and serve. Cake is best fresh, but will keep airtight at room temperature for up to 4 days, or in the freezer for up to 6 months.

  1. well, it looks as if you were up to the challenge; what a cake
    I see this on my breakfast table sometime soon

  2. Sounds totally heavenly! This is one I will have to make right away. :)

  3. This is a lovely stunner Averie! I love the honey and peanut butter. It doesn’t get better than that.

  4. Looks beautiful Averie! I love anything that calls for a heaping of streusel topping!

  5. I simply can’t handle the streusel topping on this beautiful cake! Like, why bother with the cake, just sit there with a spoon and eat all the toppings off! I can’t believe you were able to restrain nibbles while you were photographing! Tough cookie! This is a fantastic choice for a potluck and I am sure it was a huge hit. I am so making this! YUM!

  6. Oh yum!!! Do you think that recipe could successfully be cut in half to yield 9″ square cae?

    • I think you’d be safe! The other thing is that it would probably freeze just fine; make the whole thing, and keep half out, freeze the other half (well-wrapped in clingwrap and put inside a ziplock bag is how I freeze cakes/brownies). LMK if you try it!

  7. All I can say is WOW. Seriously, this sounds like something I would make and then eat all of and then have to fib about how I dropped it on the ground and that’s what happened to the rest of it because it’s not like I ate the entire thing by myself in one sitting. Nope not at all.

    I am DEFINITELY making this the next time my lady friends and I have a shindig, it looks amazing!

  8. Looks like another home run recipe, Averie. Buttermilk certainly does work a magic in breads and cakes…Like your cinnamon crusted bread which I made and turned out great! Thank you for your do-able and delicious recipes =)

  9. I would have been feeling the pressure too if 100+ foodies were going to eat my cake. I think you represented, though. This cake looks delicious!

  10. I can only imagine the amount of pressure you felt, but you went above and beyond… this cake sounds phenomenal!!

  11. So jealous of all the lucky people at Big Potluck who got to try this! I love the idea of a pb honey cake sweetened only with honey and um yeah omg chocolate chips

  12. Peanut butter, honey, buttermilk…streusel! (And only one bowl to clean!) Yes, please. :D

    This cake is a work of art!

  13. Oh goodness, this looks amazing! I would so get addicted to this ;)

  14. This combo sounds fantastic. I bought buttermilk just to make this cake! Do you think this recipe would work well in muffin tins? Thanks!!

    • I think that sounds like a total pain in the butt, to be honest! In theory it would work; but it’s way more work for you! Individual items, filling all the wells, then having to top them all with crumble bits, then getting them out – honestly unless you had a super special reason why you had to make them as muffins, just bake as directed in the cake pan.

      Plus, it will be moister baked as a cake rather than muffins. LMK how it goes!

  15. This cake rocks my world! Thanks for linking up with What’s Cookin Wednesday!

  16. Made this cake yesterday for a party. It turned out wonderful, and was a huge hit with our friends! It was so moist and flavorful! Thanks for an awesome recipe! It will definitely be one that I make often!

    • Holly that’s awesome and thanks for LMK! I am so glad to hear you loved it and were able so share it with friends. Thanks for the glowing report back – I appreciate it!

  17. OMG!!! Like everything else I have tried— AMAZING!!! It was hard enough to bake the cake because I think I could have eaten the entire batch of batter. The streusel is amazing and was so hard not to pick every last bit off. The flavor of this dessert is incredible and I can’t wait to make it again! Thanks for creating such wonderful recipes. :)

    • Thanks for the glowing comment and for trying the cake! So glad you loved it and I totally agree about the batter and the streusel-picking. I could have easily gone to town on that myself. Thanks for reading my site and trying my recipes! LMK if you try other things!

  19. Just pulled it out of the oven and it looks delicious! More importantly my whole apartment smells of sweet peanut butter goodness : )
    Made a few changes (ie, half the amount of chocolate chips, gluten free flour, two flax eggs and a little butter extract). I’ll let you know my family’s reaction. Thanks for another fantastic recipe; blessings to you!

    • Halving the chocolate chips? But why?! haha!

      Making it both GF and vegan with GF flour and flax eggs (well maybe you kept the butter though) but still, good to know you had success by the way it smells! And Lmk what your family says! Thanks for trying it!

      • Halving the chocolate was insane to me, but I’m the only one in the family that would eat chocolate at breakfast (really I’d eat it with every meal!). And no, I forgot to mention, I replaced butter with mashed banana and avocado… but it was delcious and except for a piece or two (and some crumbs), it’s gone!

      • Oh wow, you made it vegan and GF! And your family is nuts to not eat chocolate at every meal. Kidding :)

        Thanks for LMK the whole thing is almost gone – in a day! That’s awesome!

  20. I made this today,and it came out great. Thanks for a delicious recipe. The only thing I changed was that I used mini chips in place of the big chips.

  22. I’ll have to try this with Biscoff/cookie butter and see if it is as successful as your original. Can’t do PB but am so thrilled to find how many recipes I can sub in the cookie butter and still make them sort of like the originals :-)

    It sounds amazing…streusel with chocolate is always good!

  23. WOW! just found your site and its dangerous in the worst and best ways possible. Thanks for all the amazing goodies! Cant wait to try them all!

  24. Did you use natural or regular peanut butter?

  25. I just baked this AMAZING cake, and I love it!!! I will be making this for some friends too! I loved how easy it was to make and it is simply delicious!
