Now separate your cake batter into 6 bowls for the 6 colors of the rainbow and add gel dye to achieve your desired colors.

Set your ice cream cones into a cupcake/muffin tin or ice cream cone cupcake tin as shown

Add a scant 1 Tablespoon of each color to the cupcakes, starting with purple, then blue, green, yellow, orange and topping it all off with red.
