Ok - so these are SO good. Seriously. They're like two cupcake "tops" with the frosting in the middle.
1 box of Devils Food Cake Mix
1/2 cup oil
1/2 cup water
I got this sheet for making the cake parts >>>HERE<<<
1/2 cup butter, softened
1 cup creamy peanut butter
3 tablespoons milk, or as needed
2 cups confectioners' sugar
Place the butter and peanut butter into a medium bowl, and beat with an electric mixer. Gradually mix in the sugar, and when it starts to get thick, incorporate milk one tablespoon at a time until all of the sugar is mixed in and the frosting is thick and spreadable. Beat for at least 3 minutes for it to get good and fluffy.
Eat one - give the rest away! :)
