Rainbow Cake – Not so Simple but definitely Delicious

I was inspired to make a Rainbow Cake this weekend. With the passing of the law that now allows all people the gift of marriage.  I will be able to see ALL of my children marry the one they love.   Knowing they will be able to share their lives through marriage with that special person was very important to our family.  Also, Kent and I celebrated our 29th anniversary this weekend. What better way to celebrate both of these awesome events than with a Rainbow Cake.

I got the decorating idea from Food Network,  The cake recipe from Wilton and the buttercream frosting recipe is one I use all the time.

6 cups cake flour sifted
2 tablespoons baking powder
1 1/2 cups butter or margarine, softened
3 cups granulated sugar
2 cups milk
1 teaspoon vanilla extract
12 egg whites


1.  Preheat oven to 325°F. Grease bottom of pans and line with waxed paper or parchment paper.
2.  Sift together flour and baking powder. Set aside.
3.  Cream butter and sugar together until light and fluffy. Set aside.
4.  Beat egg whites until stiff, but not dry. Set aside.
5.  With mixer at slow speed, add flour mixture to butter mixture, alternately with milk. Beat well after each addition. Beat in vanilla extract.
6.  Gently fold egg whites into batter.
7.  Pour into prepared pans.
8.  Bake until toothpick inserted into center comes out clean. For this recipe the pans are about 1/2 full so 12-15 minutes is the time.

Preparing the layers
(I watched this video and it helped me tremendously!)

1.  Divide batter evenly among 6 small bowls. Starting with the lightest color, tint batter with food coloring, whisking in a few drops at a time until the desired intensity is reached.
2.  Pour each of the colored batters into a different parchment-lined cake pan (I weighed the batter and filled the cake pans by weight)  OR each should be half full.
3.  Bake until a toothpick inserted in the center comes out clean, about 12 to 15 minutes.
4.  Stack layers according to the colors of the rainbow.  Purple, blue, green, yellow, orange and red.june 026june 027
5.  Spreading a thin layer buttercream between each. june 028Using an offset spatula, frost the whole cake with a thin layer of buttercream frosting.june 029
6.  To apply sprinkles you need to start from bottom and apply with your hands. june 030 This video helped with applying sprinkles.

I have never done anything like this before.  This definitely was not simple.  It was very time consuming since I only own 2 round cake pans.  Also, preparing the layers took some time.  For me, it was worth the 5 hours that it took me from start to finish (yes, 5 hours).  It tasted delicious and looks fabulous!!june 044
