1. Line two baking sheets: Start by lining two baking sheets with parchment paper. This will prevent the cake balls from sticking.
2. Prepare cream cheese: In a large mixing bowl, beat 8 oz. of softened cream cheese using an electric mixer until light and fluffy. This will create a creamy filling for the cake balls.
3. Crumble the snack cakes: Take 10 Little Debbie vanilla Christmas tree snack cakes and crumble them into the cream cheese mixture. Mix until combined; the mixture should resemble a thick dough.
4. Form the cake balls: Using a tablespoon, scoop the mixture and roll it into balls approximately the size of a tablespoon. Place them on one of the lined baking sheets.
5. Chill the cake balls: Transfer the baking sheet to the freezer and let the cake balls freeze for about 30 to 45 minutes until they are firm to the touch.
6. Melt the chocolate: In a microwave-safe bowl, melt 20 oz. of white chocolate melting wafers according to package instructions. Stir until smooth and fully melted.
7. Coat the cake balls: Dip each frozen cake ball into the melted white chocolate using a fork, letting the excess chocolate drip off. Place them back on the parchment-lined baking sheet.
8. Decorate: Use a piping bag filled with 6 oz. of red vanilla flavored melting candy wafers to drizzle decoratively over the white chocolate-coated cake balls. Immediately sprinkle 1 tbsp of green sanding sugar on top for a festive touch.
9. Let set: Allow the cake balls to sit at room temperature for about 15 to 20 minutes until the chocolate coating sets before serving.
