It took a small box of each flavor of gelatin in the double recipe so no measuring needed.
Multi flavoured rainbow cake.
Grease and flour 2 9 inch round pans.
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.
I wanted my layers to be full size 9 inch layer cakes and not thin.
Cover the cake with chocolate buttercream taking care to keep track of what layer is where.
Allow the cake layers to cool completely.
Of course if vanilla is your thing then you can easily make this cake a vanilla rainbow cake too.
I rrrrreally like it with cream cheese frosting though.
Reline and grease the pans and bake the final three layers.
Then i added the eggs and self raising flour and split the mixture between three bowls.
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.
Cover bottoms with parchment.
Pour half into separate bowl.
Repeat with blue green yellow orange and red cake layers.
It s one of my go to cake flavors whenever i m making something for a crowd.
Bake cake for 25 to 30 minutes until layers are fragrant and spring back when touched.
One cake mix makes only 2 full sized layers.
Trim rounded tops off cakes to level if needed.
Allow the cake to cool for up to 2 hours.
It s kind of a cross between a white cake and a hummingbird cake in flavor.
Allow the cakes to cool in the pans for 5 minutes then turn out onto a wire rack.
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.
Prepare cake batter from 1 pkg.
Spread with frosting to within 1 4 inch of edge.
Cake mix as directed on package.
Spread light coat of frosting on top and side of cake to seal in crumbs then frost with remaining frosting.
