Rainbow Cupcakes with (new) Buttercream Frosting

Not going to lie, these do take some time to make but the looks on peoples faces will make it all worth it!!

I used 2 white cake mixes (following the directions on the box).  Separate out the batter into 6 bowls.  Add your food coloring to get the color of each that you want.

I started with the red.  You will use a small amount of each color.  Using the teaspoon you used to mix up each color you will use about 1/2 of that teaspoon of each color.  Remember you only want to fill each paper to around 2/3 full.

Here is a picture of the red in the bottom and the small dab of orange on it.  You will want to spread out each color as you add it.  Best way to do that is by dipping one of your fingers in water and starting from the center circle out.  You will get the hang of it pretty quick as you will be doing that alot.



Here are the cupcakes pre-baking with all the layers.  As you can see I didn't spread the purple all the way out.

Here is a close-up of one.  You can see some of the other colors on the edges, that is ok!

Here they are all baked up and very colorful!

Let the cupcakes completely cool before frosting. 

To make the frosting you will first cream 1 stick unsalted butter (at room temp) with a hand mixer, will be nice and smooth.  Next add 1 teaspoon of pure vanilla extract, blend in with mixer.  With the mixer slowly add in 2 cups of sifted powdered suger, making sure to scrape down the sides of the bowl now and again until blended.  Next add 2 tablespoons of cold milk or light cream.  Beat on high for 3-4 minutes, if it seems a little runny add just a bit more sugar and mix a bit more.

On how I frost the cupcakes you can see my blog on Don't Be Blue Cupcakes.

Here is the cupcake cut open!

Here is the outside without the wrapper.

To add a little more fun I put a gold coin (plastic) in the top, you know how you find gold at the end of the rainbow!!

Enjoy and happy baking!!
