Chocolate Chip Peanut Butter Cake


Everyone knows that I’m a big fan of chocolate and peanut butter, and I was in the mood to bake with it one night.  I also wanted to try a chocolate-peanut butter frosting.  I’ve tried and loved a peanut butter frosting recipe, but I wanted to try a recipe where they were together.  I’ve had this cake bookmarked for a long time now, and I thought it would be the perfect cake to pair with this frosting.  This cake had a strong peanut butter flavor that was just right.  The peanut butter made it nice and moist.  The recipe says to use three 9×2-inch pans, but there is no way I could have put this batter into three pans.  I used 2 pans and the cake was still fairly thin.  If you want a thick three-layer cake, I would suggest doubling the recipe.  The cake came out just fine in two layers, though, so you can do it either way. The frosting was amazing.  It had the perfect balance between chocolate and peanut butter.   I will definitely be using this recipe again!  This was just what I was looking for!

Peanut Butter Peanut Butter Chip Cake
Source: Death By Chocolate Cake via Culinary Concoctions by Peabody

1/2 stick unsalted butter
1 cup all purpose flour
1/4 teaspoons baking soda
1/4 teaspoons baking powder
1/4 teaspoons salt
1/2 cup tightly packed brown sugar
3 ounces creamy peanut butter
1 large egg
1 egg yolk
1/4 cup sour cream
1/4 cup hot water
1/2 tsp pure vanilla extract
1/2 cup peanut butter chips or chocolate chips

Preheat oven to 325F.

Grease two 9 x 1 1/2 inch pans.  Line your bottoms with parchment. Set aside.

Combine flour, baking powder, baking soda, and salt.

Mix together brown sugar, peanut butter and butter for two minutes. Add egg and egg yolk and mix for another 2 minutes. Scrape down the sides and mix for another minute.

Add half of the flour mixture and mix until incorporated about 20 seconds. Then add the sour cream, mixing again for 20 seconds. Gradually add the remaining flour mixture.  Add the hot water in a slow, steady stream and mix on low to combine, about 30 seconds. Add the vanilla and mix for another 10 seconds. Add the peanut butter chips and use a rubber spatula to finish mixing the ingredients until thoroughly combined.

Divide the cake batter into the prepared pans, spreading it evenly. Bake for about 22 minutes. If you have 4 inch diameter tart pans like I used, it takes the same amount of time to bake the cake, if not a few more minutes. Use a knife to see if it is done.

  1. Yeah, that one is one of my favorites. Seeing yours makes me want to make it again.

  2. this looks gorgeous!

  3. That looks like pure happiness!

  4. That cake made me smile for the first time in 4 days.


  5. looks delicious, but I have a couple questions. From your picture it seem like you have chocolate chips in the cake but I only see peanut butter chips listed in the recipe. Also for the frosting, I am assuming you mean 1/4 cup of peanut butter?

    • Sorry- I didn’t edit carefully this time! It’s 1/4 cup peanut butter and you can use either peanut butter or chocolate chips- I fixed it!

  6. Holy cow, that looks incredible. Makes me want a very VERY large glass of milk

  7. On your recipe it says 2 oz of butter but on the original is says 2 sticks. Which is right?

  8. I have a question: how much is two oz of butter? And is it necessary to line the pans with parchment or will a non-stick spray work as well?
    This looks amazing.

    • Two ounces is 1/2 stick. I like to use parchment because it’s easier to get the cake out, but it’s not necessary.

  9. When you add peanut butter and chocolate to a cake, there’s nothing that can be wrong with it! Yum!!

  10. I am also a big fun of peanut butter and chocolate so I go crazy when I see this cake. It looks so delicious, I will try this recipe this weekend.

  11. My friend’s birthday is Monday and I plan on making this cake for her. She LOVES peanut butter and chocolate, especially together. My question is can I make the frosting a couple days before making the cake or do you think it wouldn’t turn out so great?

  12. question !! if i only wanted to make a chocolat icing.. can i just take out the penut butter!! will it mess up the icing
