3 Tbsp unsalted butter
1 package miniature marshmallows
1/2 cup creamy peanut butter
5 cups Quaker Whole Hearts Cereal
1 cup Valentine M and M candies
Line a 9 X 13" pan with parchment paper and spray with baking spray.
Place butter and marshmallows in a large microwave safe bowl. Microwave on high for 1 1/2 minutes or until melted. Stir in peanut butter until blended. Add the cereal and the candies and mix. Spoon into prepared pan, and flatten down evenly. Cool, then cut into heart shapes with a cookie cutter, or slice into squares.
