Rice krispie treat recipe

1/2 stick butter (Fleischmans unsalted) 4 cups mini marshmallows 2 tbl Hersheys cocoa 6 Cups rice cereal (Malt O Meal choc Dino-bytes work well) Grease 9 x 11 pan. Melt butter over low-medium heat. Add marshmallows. When the marshmallows are about half-melted, stir in cocoa. (The cocoa cuts down on the sweetness & makes it more chocolatey) When the marshmallows are completely melted, take off the heat. If you don't, they will be as hard as rocks. Stir in the cereal. Press into greased pan.
