Instructions

Step 1: Preheat and Prepare Pans

Preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans to ensure the cake doesn’t stick. You can also line the bottoms with parchment paper for extra assurance.

Step 2: Make the Cake Batter

In a large mixing bowl, whisk together the flour, baking powder, and salt. Set aside. In a separate bowl, cream together the butter and peanut butter until light and fluffy. Add the sugar and continue to beat until the mixture is smooth. Beat in the eggs, one at a time, then add the vanilla extract.

Gradually add the dry ingredients into the wet ingredients, alternating with the milk, starting and ending with the flour mixture. Mix until just combined—don’t overmix.

Step 3: Bake the Cake

Divide the batter evenly between the two prepared cake pans and smooth the tops with a spatula. Bake for 25-30 minutes or until a toothpick inserted into the center comes out clean. Allow the cakes to cool in the pans for 10 minutes before transferring them to a wire rack to cool completely.

Step 4: Make the Peanut Butter Frosting

While the cake is cooling, make the frosting. In a large bowl, beat the butter and peanut butter together until creamy. Gradually add the powdered sugar, 1 cup at a time, and beat until smooth and fluffy. Add the vanilla extract and a splash of milk, then continue to beat until the frosting is spreadable. If it’s too thick, add a little more milk until it reaches your desired consistency.

Step 5: Frost the Cake

Once the cakes are completely cool, spread a layer of frosting on top of the first cake. Place the second cake on top and frost the entire cake with the remaining frosting. You can decorate with chopped peanuts, chocolate chips, or drizzle with melted chocolate if you like.

Step 6: Serve and Enjoy

Slice and serve your Peanut Butter Cake with Peanut Butter Frosting! You won’t be able to resist this rich, creamy dessert—perfect for any occasion.
