Ingredients

16 cups (a 13 1/2-ounce box) crisp rice cereal 

12 cups mini marshmallows 

10 tablespoon unsalted butter, melted 

Assorted colorful cereal and candies for decorating 

Preparation

Melt butter over low heat in a large saucepan. Add mini marshmallows; stir until melted, about 10 minutes.

Stir in crisp rice cereal.

Cars and bugs are shaped by hand. Work quickly while mixture is soft and sticky: Spoon into greased bowl; cover with plastic wrap so it doesn’t harden.

Butter hands, and make shapes one at a time. Boats, flowers, and hills are cut out after the mixture has hardened.

Spoon the warm mixture into a greased 9-by-13-inch pan; pat smooth. Let set, uncovered, 30 minutes to an hour, and then cut out.
