This Instructable will show you how to make awesome rainbow cupcakes that not only look good but taste good too! Your friends will only think it took you forever to make these cupcakes. Only you will know that it did not take all day to make them.
Step 1: Gather everything you will need in one place
To make awesome rainbow cupcakes you'll need the following:
Step 2: Put the cupcake liners in the cupcake pan
Put the cupcake liners in the pan and double up on them because they keep the cupcake shape better. You can always take off one or both liners before presenting.
Step 3: Prepare the cake mix according to the directions on the box
Prepare the cake as per the directions on the box. I substituted egg whites for real eggs.
Step 4: Mix!
Mix all the wet ingredients with the dry mix until smooth but do not over mix. Over mixing will cause the batter to be too dense when baked, it will not bake correctly and will be more like a pudding. Smooth batter also facilitates in mixing in the dye.
Step 5: Time to add the food coloring!
Step 6: Mix the food coloring in the batter
Now this is the fun part because you get to be as creative as you want! Once you have added the food coloring, mix with a fork and add more food coloring as needed. The more food coloring you add the darker the rainbow colors will be.
Step 7: Add the layers of the rainbow

Now decide in which order you would like the colors of your rainbow and pour each layer, making sure to cover the previous layer. You can play around with the batter at this point and you can make some layers thicker than others or you can make your layers the same thickness. I tried to make these the same thickness.
Step 8: Now put the rainbow cupcakes in the oven
Using the baking instructions on your cake box, bake the cupcakes!
Step 9: Check to see if the cupcakes are done using a wooden skewer
Since rainbow cakes are no good to anyone if they are under baked, use a wooden skewer to check to see if they are done. If batter comes off on the wooden skewer bake a few more minutes. If the skewer comes out clean, your cupcakes are done! Take the cupcakes out of the cupcake pan and let them cool.
Step 10: Let's see what the inside of the rainbow looks like
The layers look great and the taking off the second cupcake liner allows you to really see the nice rainbow patter while the cupcake is still intact. I am showing the cupcake cut in half so that you do not have to "destroy" a perfectly good cupcake. :-)
Step 11: Time to frost
This is the easiest part. Once and only once the cupcake has completely cooled off, you can start frosting the cupcakes. All you have to do is open the can of frosting and start frosting. I used a dinner knife but any knife will do.
Step 12: Your rainbow cupcakes are done!
Now that the cupcakes have been frosted, now it is time to dazzle your guests with your fantastic cupcakes!
