Peanut Butter Sheet Cake with Peanut Butter Frosting
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
Directions:
Preheat your oven to 350°F (175°C) and grease a 9×13-inch baking pan.
In a large mixing bowl, combine the yellow cake mix, eggs, softened butter, water, and creamy peanut butter. Beat on low speed for 30 seconds, then on medium speed for 2 minutes until well blended.
Pour the batter into the prepared pan and bake for 25-30 minutes, or until a toothpick inserted in the center comes out clean. Let the cake cool completely in the pan.
While the cake is cooling, prepare the frosting. In a medium bowl, beat together the confectioners’ sugar, creamy peanut butter, softened butter, milk, and vanilla extract until smooth and fluffy. Add more milk, 1 tablespoon at a time, if the frosting is too thick.
Once the cake has cooled, spread the peanut butter frosting evenly over the top. Slice and serve!
