This video teaches the secrets of making rainbow-colored cupcakes with food coloring.
First add some oil mixed with water, cake mix and egg whites in a bowl and mix them well.
Transfer the batter to six disposable cups evenly to add the food coloring.
Now add a color (mix yellow and red to make orange and red and blue for purple) to each cup with batter and mix them well.
Now line your muffin pan with muffin tins.
Add a little batter of each color one by one to the tins carefully.
Bake it in a 325 degree preheated oven for 20 minutes.
Finally taste it and enjoy.
