Mix together:
2 (18 oz) boxes Devil's Food Cake Mix
4 eggs
2/3 c. oil
Shape into balls and place on a cookie sheet. Bake at 350 for 8-10 minutes. If you want them crunchy, leave them in longer. I personally like them soft, so when they crack on the top I take them out.
Filling:
1/2 c. margarine (I use butter)
4 oz cream cheese
2 c. powdered sugar
1/2 tsp vanilla
You can add whatever other flavoring you want. One of our favorites is mint, orange, or even coconut.
Spread frosting on one cookie. Add another cookie on top to make a sandwich and enjoy.
