I made these Pool Ball cup cakes using the book Hello Cupcakes. They were so simple! I used a standard white cake mix. Added cupcake liners and filled up half way.
After cooling I frosted them with white icing (just the standard canned icing). Then mixed up colored sugar using food color gels and white sugar. I did find in making the colored sugar that more gel actually made a better color than a less gel. Less made the color ball up and leave huge white crystals.
Then I put saran wrap on the sides to create a line then dipped the striped ones in the colored sugar then the sides in white sugar to give it a uniformed look.
The solid colors I just dipped straight in the colored sugar. Then added a dab of white icing and then wrote the black numbers on the top.
