    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.

    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.

  • 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.
