Ingredients

4 tablespoons butter, cut into pieces 

1 bag (10 ounces) mini marshmallows 

8 ounces semisweet chocolate, finely chopped 

6 cups rice cereal 

3/4 cup peanut-butter chips 

Preparation

In a large, deep saucepan, melt butter over low heat, about 4 minutes. Add mini marshmallows and cook, stirring, until melted, 6 to 8 minutes.

Add chocolate and cook, stirring, until melted, 2 to 4 minutes. Remove from heat. Quickly fold in rice cereal and peanut-butter chips until evenly distributed.

Coat a 1/4-cup dry measuring cup with nonstick cooking spray; scoop mixture onto waxed paper, forming clusters. Let set, about 10 minutes.
