2. When a fork can be inserted into the center of the cakes and comes out clean, the cakes are done baking. Remove the cakes from the pans immediately and put them on cooling racks to cool for 15 minutes.
3. Once the cakes are cooled, use a knife to hollow out the center of the round cake. This creates the upturned look of the sombrero.
4. Tint the vanilla frosting by mixing three parts yellow, two parts red, and one part blue food coloring. Adjust colors, if necessary, and mix well until you reach the desired color.
5. Frost the round cake. Place the dome cake in the center of the round cake, then frost the dome (frosting will also help the dome stay in place.)
6. Decorate using string licorice around the bottom of the dome. Further decorate with writable icing around the rim, and with jelly beans around the side.
Ole!
