Heavenly Chocolate Peanut Butter Cake

Heavenly Chocolate Peanut Butter Cake

Calling all peanut butter and chocolate lovers! Decadent, delicious, and delightful, this Heavenly Chocolate Peanut Butter Cake will surely satisfy all your cravings while leave you wanting more. As a devout peanut butter fan, I obviously had to share a recipe with it as one of the star players.

Now I’m sure you have seen “drip cakes” everywhere in the past year, so I decided to join the bandwagon and do a simple, classic pinteresty decoration. I also unfortunately had a difficult time getting the cake off the cake round and on to the cake stand, but that’s alright. I think it looks pretty good still :)


  • 2 cups all-purpose flour

  • 2 cups sugar

  • 3/4 cup unsweetened cocoa powder

  • 2 teaspoons baking powder

  • 1 1/2 teaspoons baking soda

  • 1 teaspoon salt

  • 1 1/2 teaspoon espresso powder

  • 1 cup milk, buttermilk, or almond milk

  • 1/2 cup vegetable canola oil, or melted coconut oil

  • Add milk, vegetable oil, eggs flour mixture and mix together on medium speed until well combined. Reduce speed and carefully add boiling water to the cake batter until well combined.

  • Distribute cake batter evenly between the two prepared cake pans. Bake for 28-32 minutes, until a toothpick or cake tester inserted in the center of the chocolate cake comes out clean.
