Prepare for Baking: Preheat your oven to 325°F (163°C). Grease a 9×13 inch baking pan and set it aside.
Mix the Cake Batter: In a large mixing bowl, use an electric mixer to cream together the softened butter and creamy peanut butter until well mixed. Add the eggs, cake mix, and water to the bowl and beat on medium speed for two minutes until the batter is smooth.
Bake the Cake: Pour the batter into the prepared baking pan, smoothing the top with a spatula. Bake for about 40 minutes, or until a toothpick inserted into the center of the cake comes out clean. Allow the cake to cool completely in the pan on a wire rack before frosting
Prepare the Frosting: In a mixing bowl, cream together the softened butter and creamy peanut butter until smooth. Gradually add the confectioners’ sugar, vanilla extract, and milk, continuing to mix until the frosting reaches a fluffy consistency. Adjust the thickness of the frosting by adding more milk, one tablespoon at a time, until it’s spreadable but still thick.
Frost the Cake: Once the cake has cooled, spread the peanut butter frosting evenly over the top, creating swirls or patterns for a decorative touch.
Serve and Enjoy: Slice the cake into squares and serve. This cake is perfect for gatherings, celebrations, or as a treat to brighten any day.
Tips:
For an extra peanut buttery experience, swirl in some extra peanut butter into the batter before baking or drizzle some on top of the frosting.
Ensure your ingredients, especially butter and eggs, are at room temperature to achieve a smooth batter and frosting.
If you’re a fan of texture, consider sprinkling chopped peanuts or mini chocolate chips over the frosted cake for added crunch and flavor.
