1Heat oven to 350°F. Spray 13x9-inch pan with cooking spray. Make and bake cake mix as directed on box for 13x9-inch pan, using water, oil and egg whites. Cool completely.
2Line cookie sheet with waxed paper. In large bowl, beat powdered sugar, cream cheese, butter and jam with electric mixer on medium speed until blended. Crumble cake into cream cheese mixture; mix well. Stir in dried strawberries. Shape into 2-inch balls; place on cookie sheet. Freeze until firm. When cake balls are firm, transfer to refrigerator.

Dip tip of 1 lollipop stick about 1/2 inch into melted candy and insert stick into 1 cake ball no more than halfway. Dip each cake ball into swirled candy to cover; tap off excess. (Spoon more red candy into pink candy as needed.) Poke opposite end of stick into foam block. Sprinkle with pink sugar. Let stand until set.
