Cake mix as directed on package.
Multi flavoured rainbow cake.
Allow the cakes to cool in the pans for 5 minutes then turn out onto a wire rack.
Bake cake for 25 to 30 minutes until layers are fragrant and spring back when touched.
It took a small box of each flavor of gelatin in the double recipe so no measuring needed.
Reline and grease the pans and bake the final three layers.
It s one of my go to cake flavors whenever i m making something for a crowd.
Then i added the eggs and self raising flour and split the mixture between three bowls.
I wanted my layers to be full size 9 inch layer cakes and not thin.
Repeat with blue green yellow orange and red cake layers.
Cover bottoms with parchment.
Prepare cake batter from 1 pkg.
Allow the cake layers to cool completely.
You just need to set aside some time to bake three sets of sponges then decorate your showstopper and i ve made sure there s plenty of icing so no danger of running short before the end.
Allow the cake to cool for up to 2 hours.
Step by step i own three 8 cake tins so i did three layers of the cake at a time i started by creaming the butter and sugar together with the lemon zest.
Of course if vanilla is your thing then you can easily make this cake a vanilla rainbow cake too.
A rainbow cake has long been one of my favourites for a special occasion it looks so impressive yet it s a relatively simple process.
Trim rounded tops off cakes to level if needed.
Cover the cake with chocolate buttercream taking care to keep track of what layer is where.
Spread with frosting to within 1 4 inch of edge.
So i doubled this recipe and filled my cake pans a little fuller and had enough left to make 12 regular sized cupcakes.
On serving plate place purple cake layer.
Carefully remove the aluminum wrapped cardboard from the cake pan and flip the cake out onto a cake stand.
Grease and flour 2 9 inch round pans.
One cake mix makes only 2 full sized layers.
I rrrrreally like it with cream cheese frosting though.
Pour half into separate bowl.
