Preheat oven to 350°F and grease a 9x13-inch baking pan with nonstick spray, set aside.
In a large bowl, mix together the cake mix, water, eggs, and oil.
1 (15oz.) box Red Velvet Cake Mix, 1¼ cups water, 3 large eggs, ⅓ cup vegetable oil
Pour the batter into the prepared cake pan and bake for 25 to 30 minutes. Let the cake cool completely before using, about 30 to 60 minutes.
Flip the cake upside down on a cookie sheet and trim ¼-inch off all four sides. Thinly slice off the bottom layer, approximately ⅛-inch or less. This gets rid of any dry pieces.
Break apart the cake and place in a large bowl and crumble up with hands or fork (I recommend using gloves to keep your hands clean.
Add 2 to 3 tablespoons of frosting to the bowl and mix with the cake crumbs until fully incorporated. The mixture should stick together when squeezed. A little frosting goes a long way, you don't want to add too much.
2-3 tablespoons canned cream cheese frosting
Using a medium cookie scoop, portion out the mixture and roll it into balls. You should have approximately 24 to 30 balls depending on the size. Place on a cookie sheet with parchment paper.
Freeze balls for no longer than 10 minutes.
Remove balls from the freezer and roll them again to remove any flat spots.
Add the 12-ounce bag of light green candy melts into a Microwave safe bowl and melt for 1 minute, stir, then microwave at 30-second intervals, stirring between each one until smooth.
12 ounces Light or Vibrant Green Candy Melts
Add 1 tablespoon of Melting Aid (or 2 teaspoons shortening) and stir, until thinned out. Do not add too much of the melting aid, you still want a thicker consistency to cover the color of the cake balls.
1 tablespoon Candy Melts Melting Aid
Place the melted candy melts into a taller glass such as a mason jar or wide-mouth glass, so to cover the whole cake ball when dipping.
Dip the cake balls and tap off any excess candy melts and place back on the cookie sheet with wax paper or parchment paper. (You can use a tall wooden skewer or fork to dip cake balls.
Place the dark green candy melts in a piping bag standing up in a microwave-safe mug and heat at 30-second intervals, squeezing gently with your hands, until fully melted. Snip a small piece off the bottom of the piping bag so you get a thin opening.
3 ounces Dark Green Candy Melts
Pipe the green around the cake ball and quickly sprinkle the green sanding sugar and place a small red heart on the ball. You'll want to pipe and stick on the hearts a few at a time so the melts don't harden before you get to them. Let set.
