Box of yellow cake mix (see note)
Can of frosting
1/3 cup of no sugar added applesauce
1 cup of water
18 mini Reese's Peanut Butter cups
Note: you can use any yellow, white or chocolate cake for this recipe. I like the classic yellow cake. Of course you always use your scratch cake recipe instead of a box recipe. I also substituted the applesauce for the oil in the recipe so they are a bit lower in fat.
Note: For a mess free and easy way to get an equal amount of batter into each liner use an ice cream scoop.
