Rainbow Sherbet Roll
Makes:12 servings

1 package Betty Crocker 1-step white angel food cake mix
1 1/4 cups cold water
Powdered sugar
1 1/2 cups raspberry sherbet, softened
1 1/2 cups orange sherbet, softened
1 1/2 cups lime sherbet, softened

Preheat oven to 350ºF. Line 15 1/2x10 1/2x1-inch jelly roll pan with waxed paper.

Beat cake mix and cold water in extra-large glass or metal bowl on low speed 30 seconds; beat on medium speed 1 minute. Spread half of the batter in pan. Spread remaining batter in ungreased 9x5x3-inch loaf pan.

Bake jelly roll pan 20 to 25 minutes, loaf pan 35 to 45 minutes, or until top springs back when touched lightly in center. Reserve loaf pan for another use. Cool jelly roll pan 10 minutes. Loosen cake from edges of pan; turn upside down onto towel sprinkled with powdered sugar. Carefully remove waxed paper. Trim off stiff edges of cake if necessary. Carefully roll hot cake and towel from narrow end. Cool completely on wire rack, about 1 hour.

Unroll cake; remove towel. Beginning at a narrow end, spread raspberry sherbet on one-third of cake, orange sherbet on next third of cake and lime sherbet on remaining cake. Roll up carefully. Place roll, seam side down, on 18x12-inch piece of aluminum foil. Wrap in foil; freeze at least 6 hours until firm. Remove from freezer 15 minutes before serving. Cut roll into 3/4-inch slices. Store wrapped in freezer.
