The budding artists at your child's party can paint their cake and eat it too. Make sure to have extra "brushes" on hand for party guests.
Trim the edges of the cake as shown and cover it with white frosting. Using a 1 1/2-inch round cookie cutter, cut out a thumbhole in the palette and frost the insides.
Next, use the cutter to lightly mark the circles in the frosting, then fill with gel icing "paints."
To make the brush, wrap the fruit leather around the base of the licorice twist and fringe the ends.
