Rainbow Cupcakes

I've been wanting to make rainbow cupcakes forever...I finally had the perfect event this weekend. 

Here's the cake recipe I used: 

Mix 3/4 cup sugar and 3/4 cup softened butter together until creamy and fluffy.

Mix in 2 eggs. 

Mix in 3/4 cup all purpose flour and 1 tsp baking powder until smooth. 

Mix in 1 1/2 tsp vanilla. 

Add 3 tablespoons milk, one tablespoon at a time, until mixed thoroughly. 

Divide batter into 6 bowls. 

Add food coloring as follows: 

Bowl 1: 8 drops red

Bowl 2: 8 drops yellow, 4 drops red

Bowl 3: 8 drops yellow

Bowl 4: 8 drops green

Bowl 5: 8 drops blue

Bowl 6: 8 drops blue, 4 drops red

Starting with purple, layer each color into 12 cupcake papers.  Smooth each layer down slightly. (I used a small spatula to do this). 

Bake at 395 degrees for 18 minutes. 

I made this easy cream cheese frosting: 

Cream 1 8oz package cream cheese and 1/4 cup softened butter together.

Mix in 1/2 tsp vanilla. 

Gradually stir in 1 cup sifted powdered sugar. 

Then I did this trick, from Better Homes and Gardens, to make letters for the cupcakes. 

I will definitely use this recipe again for making vanilla cupakes. They were delicious!
