Crumble cake in a large bowl until it resembles fine crumbs.
Add some ganache or frosting and using your clean hands, mix until cake can hold a ball shape.
You may add some more ganache/frosting if needed just until cake is moist.
Scoop about a tablespoonful of cake mixture and roll it into a tight ball between your palms and place on a plate.
Repeat until all the cake mixture has been rolled into balls.
Melt white chocolate in a double boiler or a thick-bottomed saucepan.
Dip the tip of the cake pop sticks into the white chocolate and insert into the cake balls about half-way.
Freeze for about 20 minutes.
Meanwhile prepare all of your decorating supplies.
Remove cake balls from freezer.
Dip cake balls carefully into the chocolate until covered.
Let the excess chocolate drip off.
Swirl and tap gently if needed.
Add the sprinkles while the chocolate is still wet, It will harden quickly.
Stick the decorated cake pop into a styrofoam block to finish setting.
Place into the freezer to speed up setting time.
Cover with a clear treat bag & ribbon for gift giving, if desired.
Store in a single layer, in an airtight container.
