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:
  • White cake mix (make sure it is not yellow or it will distort the colors)
  • White frosting
  • Water
  • eggs or egg substitutes (egg whites)
  • Food coloring (green, yellow, red, blue)
  • Butter/ vegetable oil/shortening
  • Large six tin muffin pan
  • Cupcake liners
  • Plastic containers to separate batter
  • Mixer or spoon to hand mix batter

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!
I'm so going to make these next time I make cupcakes! Oh, but did you know this? If you put the icing in an icing bag or a sandwich bag with a hole cut in the corner, it's easier to dole out batter. I've used this technique every time I've made cupcakes and it's never let me down!
if you got the message please sorry about that.
Huh?
Kwartzkitten, glad you stopped by and I am glad you liked the cupcakes! I did know the tip about icing in a ziplock bag but I have only tried it with icing I have made myself which is a bit more pliable than the stuff I had. I was using a store bought tub of icing and that stuff is <strong>SUPER&nbsp; THICK</strong>. But now that I think about it,&nbsp; I could microwave a bit of the store bought stuff and <strong>THEN </strong>put it in a ziplock!<br><br>BTW, if you make them, please post a pic!
Okay, no problem! But I realize now that I mistyped. I meant if you put the&nbsp;<strong>batter</strong> in an icing bag, it was easier to dole out&nbsp;<strong>batter</strong>. That ought to teach me to proofread more!
Now batter in an icing bag, now that is genius. Thanks for sharing. I'll be doing that next time.
Just glad I could help.
What have you done to Dashie!?<br><br>Either way, really awesome.
i like your picture.
rainbow foods are so popular these days :D really awesome!<br>I guess this doesn't work with chocolate dough? :(<br>now the very hard decision, rainbow cupcakes or chocolate cupcakes :o<br>
Well, you could mix chocolate in the mixture in the same way the food coloring is added so you'd get swirls of chocolate.
pic3: like a piece of modern art :D
Yes, it does look like modern art. That is, art you can eat. ;-)
im trying them right now will post a pic when there out of the oven :) So excited
That's so cool. Post a picture when you are done!
Yum, looking at this makes my mouth water, I can't wait to try!!
Post a picture and let me know how they are!
Beautiful!
Thank you!
A dash of rainbow in every bite.
Hahaha!
Exactly!
This brings up a bad memory of a certain fanfic...<br>Either way cool 'ible!<br>/)(^3^)(\
Thank you and do tell about the fanfic...
I'm going to make some of these to take to school with me. I have a friend who's a big MLP fan, and combining these with the fact that he has read cupckes, I think it will be hilarious.
If you do make them, please post a picture. I would love to see them!<br><br>Disclaimer: No MPLs were harmed to make these cupcakes, especially Rainbow Dash. :-0
Wait, I meant MLPS. :0
No! What have you done to Rainbow Dash!!!<br>Anyway, these look very delicious! I might try to make these when nave the time.
I had just repressed the memory of that abomination, and then I saw the preview picture.
Whew, that was close! Rainbow Dash is still alive and kickin'.
REA, <br><br>glad you like them and go ahead and make them, I dare you! :-)
great instructible. everystep so clearly documented--I feel like I've made these before already thank you. can't wait till my nieces and nephews visit and give me an excuse to try them out.
AntonioMDC, glad you liked the Instructable. Please post a picture when you make them, would love to see how they turn out.
