Rice Krispies treats are amazing and easy to make! I use 3-3 1/2 tablespoons of butter, one package of marshmallows, 6-6 1/2 cups of Rice Krispies. Melt the butter and add marshmallows in a pan. Remove the pan from the heat and add the cereal. Stir it until coated, then press the treats into a pan. Let them cool and then cut and eat them!
