Laura's Multi-colored Birthday Cake

Laura's Rainbow Colored Birthday Cake
So I made a cake that was inspired by a picture I saw on Facebook for my daughter’s first birthday.
The vanilla cake recipe is from The Cake Boss but the added colouring gels is my add-on.
Because I could only fit 1 pan in the oven at a time, I halved the recipe. The measurements below are for 1 layer of cake.
Thank you to Gail for telling me about colouring gels, they work so well.
The decorations are up to your own imagination, but because I’m not good at piping icing, I replaced the edges with stars bought at a shop.
The trick with the colouring gel is to remember that the cooked cake will come out a lighter colour than the raw cake mix.
1 cup sugar
2 eggs
1 cup + 60mls cake flour
1 tsp baking powder
1/2 cup milk
1/3 cup vegetable oil
1/2 tsp vanilla
3-5 drops colouring gel
Preheat oven to 180°C
In a large mixing bowl, beat sugar and eggs together until light and fluffy, about 1 minute
Add the flour (I put my flour through a sieve), baking powder, milk, oil, vanilla, and colouring gel and beat for another minute.
Grease/spray a 10 inch cake tin well
Pour cake mix into tin and bake for 20 mins or until a skewer comes out clean.
Immediately take out of tin into cooking rack.
Stack one layer on top of each other with wax paper in between once slightly cooled to allow the weight to press the cakes into non-raised layers.
It will reduce the gaps when stacking and icing.
Wait for all layers to cool completely before icing.
I used plain white butter icing for in between the layers and coloured icing for the top and sides.
