Wouldn’t it be fun to serve these Rainbow Cupcakes for a fun St Patrick’s Day dessert? We made this rainbow in a jar St Patrick’s Day treat from a boxed cake mix to celebrate a day when we all wish to be Irish. I have always had so much fun with St. Patricks Day, from giving my son green milk to sticking clovers in my girl’s hair. I never wish to pass a chance to have some fun even if all the kids are grown.

It doesn’t take long to make these fun cupcakes. You can use a white cake mix and follow the directions of the box to make the cake batter. Divide the cake batter between 5 different small bowls. In each bowl of batter add a few drops of food coloring in 5 different colors of the rainbow. Then add a spoonful of each colored batter in each pint mason jar and bake in a water bath.
But these Rainbow Cupcakes really take the cake. (pun intended) This Rainbow in a jar was a fun little challenge and so delicious. We are loving all the bright bold colors on these. These are better than finding gold at the end of the rainbow, they are so pretty and make a delicious St Patrick’s Day Treat. And that is how to make a rainbow cake or mason jar cake for St Patrick’s Day.
