How to make a Rainbow Cake.

Yesterday, I posted the picture of this cake on Facebook and had so many request to make a tutorial. Lucky for me I had already planned on posting this tutorial so had already taken progress pictures.


A special thanks to those of you who are fans on my Facebook page, I do appreciate the lovely comments as well as sharing my pictures.

Bake your favorite Vanilla Cake recipe suitable for an 8" x 2 layer cake.
Here I am using my Light and Fluffy Vanilla cake recipe because is a favorite of the person for who this cake was made. By the way I used my Italian Meringue Buttercream IMBC, the recipe I posted yesterday.



Method:
Preheat your oven to 170C / 340 F
Prepare you baking pans - Six pans for Six layers. See what I used below.
Here's my cake batter.

Divide you batter into six smaller bowls approximately.

Next add the six colors - Red, Orange, Yellow, Green, Blue and Purple.
Start with two drops and if needed add more.
Note: The colors will darken during baking so do not over do the colors. 
Type of Colors - Here I am using a mix of Wilton and Ameri-colors.
However, 

Super market brand colors - Before I became a cake decorator I have used the super market brand colors too... They work just as well.
If you do use super market brand colors - reduce the liquid in your recipe by about 6 tbsp; because super market brand colors are water based, so they will thin your batter.

Natural food coloring. - Now a days there is a lot of concern regarding the use of store bought food coloring.  Below I listed some option of fruit puree/juice that you can use to obtain these colors naturally.
Start with 2 tbsp of fruit puree/juice and add more if needed. Not that your batter will not only obtain the color of the fruit but also the taste and flavor.

Here you can see the colors - Not too dark but not too light as well.
I used two drops each.

Obviously I do not have six cake pans of the same size - So, I used the baking foils that you get at super market or cake supply store.
There are 7" round baking foils.
Line them up with parchment paper for easy removal.

Pour the batter from the six bowls into the six foils and spread them evenly. 

Bake in a hot oven at 170C/340 F for about 20 to 22 minutes. Mine took 20 minutes. 

Cool completely before you stack and decorate.
I stacked with the parchment papers to avoid them from sticking to each other. Wrapped them in plastic / cling wrap and let them sit in the fridge over night.

Natural Food Coloring option:
Green - Juice of Kale or Spinach 
Blue -  Jucie or puree of Blueberries
Purple - Juice of puree of Black berries, grapes.
Red - Beetroot juice
Pink - red currents or Strawberries
Brown - Coffee or Chocolate
Orange - Carrot juice
Yellow - yellow beet / turmeric or Saffron.
