The Recipe

Ingredients:

For the Cake:

  • 1 box yellow cake mix
  • 4 eggs
  • 1/2 cup softened butter
  • 1 cup water
  • 1/2 cup creamy peanut butter

For the Frosting:

  • 3 cups confectioners’ sugar
  • 1/2 cup creamy peanut butter
  • 1/2 cup softened butter
  • 2+ tablespoons milk (adjust for consistency)
  • 1 teaspoon pure vanilla extract

Step-by-Step Instructions:

  1. Preheat the oven: Preheat your oven to 350°F (175°C) and grease a 9×13-inch baking pan or line it with parchment paper.
  2. Prepare the cake batter: In a large mixing bowl, combine the yellow cake mix, eggs, softened butter, water, and peanut butter. Using an electric mixer, beat on medium speed for about 2 minutes until the batter is smooth and well combined.
  3. Bake the cake: Pour the batter into the prepared baking pan and smooth the top. Bake in the preheated oven for 25-30 minutes, or until a toothpick inserted into the center comes out clean. Allow the cake to cool completely in the pan.
  4. Make the frosting: In a medium bowl, beat together the confectioners’ sugar, peanut butter, and softened butter until smooth. Add the vanilla extract and 2 tablespoons of milk, beating until you achieve a smooth and spreadable consistency. If needed, add more milk, one tablespoon at a time, until the frosting reaches your desired texture.
  5. Frost the cake: Once the cake has completely cooled, spread the peanut butter frosting evenly over the top of the cake using a spatula.
  6. Serve: Slice and serve the cake immediately, or store it in the refrigerator for later. Enjoy the rich, peanut buttery goodness!

Serving and Storage Tips

  • Serving: This peanut butter sheet cake is perfect for parties, potlucks, or family gatherings. Serve it chilled or at room temperature for the best flavor and texture.
  • Storage: Store any leftover cake in an airtight container at room temperature for up to 3 days, or refrigerate for up to 5 days. You can also freeze the cake (unfrosted) for up to 3 months and frost it after thawing.

Helpful Notes

  • For extra peanut butter flavor, swirl a little more peanut butter into the batter before baking.
  • If you prefer a fluffier frosting, beat the peanut butter frosting for an additional 1-2 minutes to incorporate more air.
  • Feel free to add a sprinkle of chopped peanuts or chocolate chips on top of the frosting for added texture and flavor.
