It is important to heat treat the dry cake mix before adding it to the cream cheese. Add the dry cake mix to a medium-sized heat-safe bowl. Microwave the dry cake mix in two 30-second intervals, stirring after each interval. Allow the cake mix to cool completely before mixing into the cream cheese.
Using a medium-sized mixing bowl and a handheld mixer on medium-high speed, beat the cream cheese for 1½ to 2 minutes until completely smooth.
Sprinkle the completely cooled dry cake mix and 3 tablespoons of sprinkles over the top of the cream cheese. Continue mixing just until well incorporated.
Tightly cover the cream cheese mixture and chill in the refrigerator for 2 hours.
Line a baking sheet with parchment paper and set it aside.
Use a 1 tablespoon cookie scoop, and scoop the cheesecake dough. Roll the dough into a ball and place it on the prepared baking sheet.
Using four small heat-safe bowls, add one color of candy melt into each bowl. Microwave in 30-second intervals, stirring well after each interval, until completely melted. (You will be able to roll 7 cheesecake bites in each color.)
Roll one cheesecake bite in one of the colors. Place the coated bite onto a fork and gently tap any excess coating off. You can use a spoon to pour the coating over any bare spots. You can use a toothpick to gently push the coated cheesecake bites onto the prepared baking sheet.
While the cheesecake bite is still “wet”, sprinkle the unicorn sprinkles over the top of the coated bites. Repeat the coating and sprinkling process until all the bites are coated. Allow the coating to harden completely before serving.
Notes
Make sure the cream cheese is at room temperature to avoid lumps in the cheesecake mixture.
You can allow the uncoated cheesecake bites to sit overnight in the refrigerator before the next step. Be sure to pull them out and let them come to room temperature slightly because the cake mix may expand, and the coating may crack if you coat the bites too soon.
If the coating becomes too thick, you can reheat it in the microwave for 15-second intervals, stirring well after each interval until smooth.
