1

Heat oven to 350°F (325°F for dark or nonstick pan). Grease or spray bottom and sides of 13x9-inch pan.
2

Make and bake cake mix as directed on box for 13x9-inch pan. Cool in pan 10 minutes; remove from pan to cooling rack. Cool completely, about 1 hour. Refrigerate or freeze cake about 1 hour or until firm.
3

Meanwhile, in small bowl for each color, tint 1 cup frosting red, 1 cup frosting yellow and 2/3 cup frosting blue with food colors. Leave remaining frosting white.
4

Using serrated knife, cut rounded dome from top of cake to make flat surface; place cake cut side down. Cut cake crosswise into thirds. Cut one of the thirds in half crosswise to make 2 squares. Place cake pieces on tray.
5

To seal in crumbs, frost top and sides of 1 square cake with thin layer of blue frosting and 1 square cake with thin layer of white frosting. Frost 1 rectangular cake with thin layer of yellow frosting and 1 rectangular cake with thin layer of red frosting. Refrigerate or freeze 30 to 60 minutes to set frosting.
6

Add final coat of frosting to each cake. Frost 4 marshmallow halves with blue frosting; place in square design on blue cake. Frost 4 marshmallow halves with white frosting; place in square design on white cake. Frost 8 marshmallow halves with yellow frosting; place on yellow cake. Frost 8 marshmallow halves with red frosting; place on red cake. Store loosely covered.

Expert Tips

Create an attractive display by covering a piece of sturdy cardboard with wrapping paper, then plastic food wrap. Stretch and secure with tape. Or cover cardboard with foil or cooking parchment paper.
Use kitchen scissors to cut marshmallows. Spray blades of scissors with cooking spray to keep them from getting sticky.
Stick fork in side of marshmallow halves to hold while frosting. Use metal spatula or knife to slide marshmallow from fork onto cake. Smooth frosting on marshmallow with spatula.
