Preparation Steps

• Preheat the oven to 350°F (175°C). Grease and flour two 9-inch round cake pans.
• In a large bowl, mix together the flour, sugar, baking powder, baking soda, and salt.
• Add the softened butter and creamy peanut butter to the flour mixture and beat until combined.
• Add the vanilla extract and eggs, one at a time, beating well after each addition.
• Gradually add the buttermilk, mixing until the batter is smooth.
• Divide the batter evenly between the prepared cake pans.
• Bake for 30-35 minutes or until a toothpick inserted into the center comes out clean.
• Allow the cakes to cool in the pans for 10 minutes, then transfer to a wire rack to cool completely.
• To make the frosting, beat together the confectioners' sugar, heavy cream, and your choice of peanut butter until smooth and creamy.
• Frost the cooled cake layers and stack them. Garnish with chopped nuts if desired.
