Rice Krispie Treats

Ingredients:
3 T butter
1 bag mini marshmallows
Up to 6 cups rice krispies

Instructions:
1. In large saucepan melt butter over low heat. Add marshmallows and stir until completely melted. Remove from heat. 
2. Add rice krispies until you like the consistency (I usually don't add a full 6 cups) and stir until well coated. 3. Using buttered spatula or wax paper evenly press mixture into 13 x 9 x 2-inch pan coated with cooking spray. 
4. Cool. Cut into squares.
