Christmas Tree RICE KRISPIES TREATS®

Microwave butter in large microwaveable bowl on HIGH 45 sec. or until melted. Add marshmallows; toss to evenly coat. Microwave 1-1/2 min. or until marshmallows are completely melted and mixture is well blended, stirring after 45 sec. Stir in food coloring.

Add cereal; mix well. Press onto bottom of 13x9-inch pan sprayed with cooking spray. Top with sprinkles; press gently into cereal mixture to secure. Refrigerate 15 min.

Remove cereal mixture from pan. Cut lengthwise in half to form 2 long rectangles, then cut each rectangle diagonally into 6 triangles to resemble Christmas trees. Press 2 scrap pieces from ends of each rectangle together to make additional tree. (You will have 14 trees.)

Press confetti star into top of each tree. Insert pretzels into bottoms of trees for the trunks.
