Melt together ¼ cup margarine and 4 cups marshmallows. Stir in ½ cup chocolate chips until melted. Stir in coconut, Rice Krispies, and oatmeal.
Press into a 9×13″ pan that’s lined with tin foil (to save on washing!) and sprayed with non-stick spray.
Melt together remaining margarine, marshmallows and chocolate chips. Spread on top of coconut layer. Set aside to set completely (I like to leave it in the fridge).
They are fine sitting at room temperature, but I like to store them in the refrigerator or freezer so they don’t get too soft and stick together.
