1 box Devils Food cake mix
1 stick of butter
1 tub of Vanilla icing
Mix the cake mix, butter (melted) and egg together. This will form a slightly crumble type batter. Form small balls (approx 1 1/2" diameter) and place on a cookie sheet in even numbers. Bake at 350* F for 8-10 minutes. Allow to completely cool. Pair up cookies and place icing in between each pair.
the mix is kind of dry but mashes together to form balls
I usually fit a dozen cookies or more on a cookie sheet...they don't spread to much with baking
