Prepare and bake cake mix according to package directions, using a greased 13-in. x 9-in. baking pan. Cool completely on a wire rack.
Crumble cake into a large bowl. Add the frosting, jam, liqueur and food coloring if desired; mix well. Shape into 1-in. balls. Place on baking sheets; insert sticks. Freeze for at least 2 hours or refrigerate for at least 3 hours or until cake balls are firm.
In a microwave, melt dark candy coating. Dip each cake pop in coating; allow excess to drip off. Insert cake pops into a styrofoam block to stand. Melt pink candy coating; drizzle over cake pops. Decorate some cake pops with sprinkles and sugar if desired. Let stand until set.
