St. Patrick's Day Rice Krispie Treats
1/2 cup unsalted butter
1 bag mini marshmallows
4 cups rice krispies
4 cups Lucky Charms
1/2 cup mint chips
Line a 13x9-inch pan with foil; coat foil with nonstick cooking spray.
Melt butter in a large pot over medium heat; stir in marshmallows until melted. Turn heat off and stir in cereal until well combined. Spread and press into pan. Sprinkle mint chips on top; press lightly with fingers so they melt and stick to the cereal.
Cool completely. Lift out foil-lined treats, place on a cutting board, peel down foil, and cut into treats.
