“Life is like a rainbow,
You need both sun and rain to make its colour appear”


It turns out that I’m not the only one in love with rainbows!

Every child below 10, that’s celebrating its birthday, regardless whether girl or boy, loves rainbows or rainbow cakes.

I’ve made several of these rainbow tie-dye cakes lately, and they are fun to do.

Yes, they involve more washing up, and LOTS of gel colours, but they are simple enough to make, and dramatic when cut.

Six year old Nandini wanted a rainbow cake, and I decided to make a little Rainbow Dash to go on the cake.

What you need:

A tasty vanilla cake batter
Gel colours in purple, blue, green, yellow, orange and red
6 equal sized bowls
6 spoons
2, 8″ round tins, lined and sprayed

I used my yummy 1-2-3-4 recipe as the base, and divided it between 6 bowls.

Each portion was coloured with food coloring gels to make deep colours.

Starting with the purple, pour it into the bottom of each tin.

Pour the blue batter onto the purple. It will spread the purple batter out to the edges of the tin.

Next, pour the green. Follow with the yellow, orange and end with the red.



Once the batter it poured into the tins, gently rap the base of the tin on a folded towel, to spread it out.

Bake in a preheated oven for 30-35 minutes, or until the cake is done.

Cool the cakes, then wrap in cling film and freeze for a day.

To frost and decorate, you need:

Buttercream of choice
Cake boards, 8″, 12″
Serrated knife
Offset spatula
Gel colours

Tort the cakes to form 4 layers. You will have a vibrant rainbow cross section.

Use a little buttercream to “stick” down the first layer onto an 8″ cake board.

Use a good 1/2 cup of frosting between each layer, ending with the flat bottom of one of the cakes, on top. I left my buttercream white, as the cake was colourful enough, and I planned on putting a rainbow on the sides.

Crumb coat the cake. Chill. Then cover again with a generous coating of frosting.



While the crumb coat was chilling, I coloured my fondant, using the same 6 colours I’d used for the batter. I rolled thin cylinders and formed them around a glass bowl to create a curved shape.

Since I had a lot of left over fondant, I made little balls in each colour, to use as a border.

Once the cake is finished, move it onto the larger cake board, securing in place with a daub of buttercream.

I added the rainbow to the side of the cake, then used the balls of fondant to form a border.





The pièce de résistance was the little Rainbow Dash topper on the cake!

Have a wonderful rainbow filled day!
