I've made the classic Rice Krispies Treats, but used strawberry marshmallows instead of regular. Oh, and also sprinkles and cut out into hearts...so sweet!
Strawberry Rice Krispies Treats
6 1/2 cups Rice Krispies
1 8oz bag Strawberry Marshmallows
1/2 stick butter
Melt butter in large pan. Once melted, add marshmallows. Stir until marshmallows are melted. After melted, add sprinkles, as much or little as desired. Then add Rice Krispies and stir until thoroughly incorporated. Press Rice Krispies mixture into a greased pan (9x13 or larger...whatever you want) and let sit about 5 minutes. After 5 minutes take your heart cookie cutter and press out hearts. Let dry on waxed paper.
P.S. It would be super tasty to add 1/4 cup strawberry cake mix when adding sprinkles. Amp up the strawberry flavor, so good!
