Ingredients
Scale
Cake
- 2 cups all-purpose flour
- 2 teaspoons baking powder
- 1/2 teaspoon baking soda
- 1/2 teaspoon salt
- 1/2 cup unsalted butter, softened
- 1 cup creamy peanut butter
- 1 cup granulated sugar
- 1 cup brown sugar, packed
- 2 large eggs
- 1 teaspoon vanilla extract
- 1 cup buttermilk
Frosting
- 1/2 cup unsalted butter, softened
- 1/2 cup creamy peanut butter
- 3 cups powdered sugar
- 1/4 cup milk
- 1 teaspoon vanilla extract
Instructions
- Preheat and Prepare Pan: Preheat your oven to 350°F (175°C). Grease and flour a 9×13 inch baking pan to prevent the cake from sticking.
- Mix Dry Ingredients: In a medium bowl, whisk together the all-purpose flour, baking powder, baking soda, and salt. Set this mixture aside for later use.
- Cream Butter and Sugars: In a large bowl, use a mixer to cream together the softened unsalted butter, creamy peanut butter, granulated sugar, and packed brown sugar until the mixture is light and fluffy, which should take about 2-3 minutes.
- Add Eggs and Vanilla: Beat in the eggs one at a time to the creamed mixture, ensuring each egg is fully incorporated before adding the next. Stir in the vanilla extract until evenly combined.
- Combine Batter: Gradually add the flour mixture to the creamed ingredients, alternating with the buttermilk. Begin and end with the flour mixture. Mix the batter just until combined; avoid overmixing to ensure a tender cake.
- Pour and Bake: Pour the batter into the prepared pan and smooth the top evenly. Bake in the preheated oven for 30 to 35 minutes, or until a toothpick inserted into the center comes out clean.
- Cool the Cake: Remove the cake from the oven and allow it to cool completely in the pan on a wire rack before frosting.
- Prepare Frosting: In a bowl, cream together the softened butter and creamy peanut butter until smooth. Gradually add the powdered sugar, milk, and vanilla extract, beating continuously until the frosting is light and fluffy.
- Frost the Cake: Spread the prepared peanut butter frosting evenly over the cooled cake. Slice, serve, and enjoy!
Notes
- Ensure the cake is completely cool before frosting to prevent the frosting from melting.
- You can substitute creamy peanut butter with natural peanut butter but the texture might slightly vary.
- For a more intense peanut flavor, consider adding a teaspoon of peanut butter extract to the batter.
- This cake stores well covered in the refrigerator for up to 4 days.
- Bring the cake to room temperature before serving for best flavor and texture.
