My boys love making rainbow cupcakes (well, really, any cupcakes), so we decided to make pot of gold rainbow cupcakes tonight to get in the St. Patrick's Day spirit.
I split a white cake mix into 7 different bowls. I colored each of the bowls a different color: red, orange, yellow, green, blue, and violet. Then I put a scoop of each color in a cupcake liner.
When they were baked and cooled, I piped green frosting on the cupcake using a "grass" tip.
With black sparkle food gel, I drew on a pot. I added gold sprinkle balls to the pot and put on some rainbow sprinkles.
On some of the other cupcakes, I simply added pastel egg sprinkles.
This is what they look like on the inside.
