1 cake mix
2/3 c. butter
1/4 c. water
2 eggs
1 c. marshmallows
1 c. chocolate chips
1/2 c. nuts

Mix well. Will be very thick, like cookie dough. (You may add other things like coconut, caramel chips, M & M's or whatever you have on hand.) Press into pan. Bake at 350 degrees for 35 minutes or so. Frost with powdered sugar glaze while still warm.
