Dry Ingredients
- 2 cups all-purpose flour
- 1/4 cup cocoa powder
- 1 teaspoon baking soda
- 2 cups granulated sugar
Wet Ingredients
- 1 cup unsalted butter
- 3 large eggs
- 1 cup buttermilk
- 1 teaspoon vanilla extract
- 1/2 cup creamy peanut butter (for batter)
Peanut Butter Frosting
- 1/2 cup unsalted butter, softened
- 1 cup creamy peanut butter
- 3 cups confectioners’ sugar
- 2–4 tablespoons milk or cream (to desired consistency)
- Prepare the batter: In a large mixing bowl, whisk together the dry ingredients: all-purpose flour, cocoa powder, baking soda, and granulated sugar. In a saucepan, melt the butter and stir in the peanut butter until smooth. Gradually add the eggs, buttermilk, and vanilla extract to the butter mixture, then combine thoroughly with the dry ingredients to create a smooth, lush batter.
- Bake in a sheet pan: Pour the batter evenly into a greased sheet pan lined with parchment paper. Bake in a preheated oven at 350°F (175°C) for 25-30 minutes, or until a toothpick inserted into the center comes out clean, ensuring a moist but fully set cake.
- Make the peanut butter frosting: While the cake cools, beat together softened butter, creamy peanut butter, confectioners’ sugar, and milk until smooth and fluffy. Adjust milk or sugar as needed to achieve a spreadable consistency.
- Frost and serve: Once the cake is completely cooled, spread the frosting evenly over the top. Optionally, garnish with crushed peanuts, chocolate shavings, or a light dusting of cocoa powder before slicing and serving.
Notes
- Use room temperature ingredients for even mixing and smooth frosting.
- Do not overbake; check the cake a few minutes early to keep it moist.
- Creamy peanut butter is best for a smooth frosting texture.
- Allow the cake to cool completely before frosting to prevent melting.
- Lining the sheet pan with parchment paper makes removal and cleanup easier.
