Bake the cake according to the directions on the box and allow to cool
Break the cake into small pieces and add to a large mixing bowl (you don't want it to be mushy, just into small pieces)
Add frosting to the cake, and mix well until thoroughly blended into the cake (but not mushy). Make sure there aren't any clumps of frosting. You may need to use your hands
Spoon a bit of mixture out of the bowl and roll into 2-inch balls, making a hole with your thumb at the top, and pushing a Hershey kiss inside, then place another small piece of cake mixture and cover the top, then roll into a ball and place on a parchment paper lined baking sheet. Place in the freezer for 30 minutes
Add the chocolate chips and coconut oil to a microwave-safe bowl and cook at 1-minute intervals until it's smooth and creamy, stirring in between.
Remove the bites from the freezer and drop them one at a time into the chocolate. Using a slotted spoon, remove them from the bowl, allow excess chocolate to fall off, and place them on a baking sheet lined with parchment paper.
Place them back on the parchment paper-lined baking sheet and freeze for one hour.
Melt the white chocolate in the microwave with coconut oil, then separate it into two small bowls. Add red and green dyes to one and mix until you get the desired color. Drizzle both colors across the top, then add the sprinkles.
Allow to fully dry before eating.
