01 - Prepare vanilla cake according to package directions or homemade recipe. Bake until golden and tester comes out clean. Cool completely on wire rack before proceeding.
02 - Beat softened cream cheese and butter in medium bowl until smooth and creamy. Add powdered sugar gradually, mixing until fully incorporated. Stir in vanilla extract until frosting is uniform and spreadable.
03 - Crumble cooled cake into fine pieces in large bowl. Add frosting one spoonful at a time, mixing with hands or spatula until mixture holds together when pressed but remains pliable. Texture should be moist, not wet or dry.
04 - Portion mixture into 24 equal pieces. Roll each into smooth ball, then gently flatten and shape into teardrop or triangular wedge to resemble watermelon slice. Place on parchment-lined baking sheet.
05 - Melt small portion of green candy melts in microwave in 30-second intervals. Dip tip of each lollipop stick into melted candy, then insert straight into center of each cake pop. Freeze for 20 minutes until set firm.
06 - Melt pink candy melts with ½ tsp vegetable oil if needed for thin consistency. Dip each chilled cake pop into melts, angling to coat top and sides while leaving bottom exposed for rind. Tap gently to remove excess. Press mini chocolate chips into wet surface as seeds while coating is still tacky.
07 - Melt green candy melts until smooth. Dip bottom portion of each partially coated pop into green melts to create rind effect. Stand pops upright in cake pop stand or styrofoam block to set completely at room temperature or refrigerate until firm.
