01 - Bake the vanilla cake according to package directions or your preferred homemade recipe. Allow to cool completely before proceeding.
02 - In a medium mixing bowl, beat softened cream cheese and butter until combined. Add powdered sugar and vanilla extract, mixing until smooth and creamy.
03 - Crumble the completely cooled cake into fine pieces in a large bowl. Add frosting gradually, one spoonful at a time, mixing until the mixture holds together when pressed but remains pliable. The texture should be moist, not wet.
04 - Portion the mixture into 24 equal pieces. Roll each portion into a ball, then gently press and shape into a teardrop or rounded triangle to resemble a watermelon wedge.
05 - Melt a small quantity of green candy melts according to package instructions. Dip the tip of each lollipop stick approximately 1/2 inch into the melted coating, then insert into the pointed end of each cake pop shape. Freeze for 20 minutes to set.
06 - Melt pink or red candy melts, adding vegetable oil if necessary to achieve a smooth, dippable consistency. Working with one pop at a time, dip the chilled cake pop into the coating, covering completely except for the very bottom. Gently tap to remove excess coating. Immediately press mini chocolate chips into the wet surface to create watermelon seeds.
07 - Melt green candy melts. Dip the bottom portion of each coated cake pop into the green coating to create the watermelon rind effect, approximately 1/4 inch up from the base. Place in a cake pop stand or styrofoam block to set completely.
08 - Allow cake pops to set fully at room temperature for 30 to 60 minutes or refrigerate for faster setting. Serve once coating is completely firm and no longer tacky to the touch.
