Granny’s Patchwork Quilt Cake

Heat oven to 350°F. Grease bottom and sides of 13x9-inch pan with shortening or spray with cooking spray. Make and bake cake as directed on box for 13x9-inch pan, using water, oil and eggs. Cool 10 minutes. Remove cake from pan to cooling rack. Cool completely, about 1 hour.

On 13x9-inch cake board or platter, place cake upside-down. Cover surface of cake with 1 container of the frosting, using off-set spatula. Refrigerate cake 45 minutes or until frosting is firm.

Apply second coat of frosting to cake, evening surface and filling any gaps that may be present at bottom edge of cake.

Score top of cake with dull edge of large knife to make 12 squares. Decorate alternate squares with multicolored sanding sugar. Fill in remaining squares with clear sanding sugar.

For flowers, cut each marshmallow in half using clean kitchen scissors. Dip green marshmallow halves into green sanding sugar; dip yellow marshmallow halves into yellow sanding sugar. The sugar will coat cut edges of marshmallows. Place dime-size dot of frosting in center of each white square on cake. Arrange 5 marshmallow “petals” into flower shape, sugared-side-up, on top of each frosting dot; press to adhere. Press yellow sugar pearl into center of each flower. Store cake loosely covered.
