Break the cooled cake into small crumbs using your hands or a mixer. Add the 1/2 cup frosting of your choice (use chocolate if mirroring Starbucks cake pops) and mix together until combined.
Roll cake mixture into 1 inch balls using your hands or a small cookie scoop. Place on cookie sheet and chill for at least 20 minutes.
After the cake balls have cooled, melt the chocolate wafers in a 2 quart glass measuring cup for 30-second intervals in the microwave, stirring in between.
Dip the tops of the cake pop sticks into the dipping chooclate about 1/2 inch. Place the chocolate end of the stick into each cake pop and push it about 3/4 of the way into the cake ball.
Take 3-4 cake balls out of the fridge at a time and dip them completely in the chocolate. Gently tap the stick on the side of the cup to remove any excess chocolate. Decorate with sprinkles immediately. Place standing up in the cake stand to set.
Cake pops will be hard to the touch in about 5 minutes and ready to stack or move in 30 minutes.
