Funfetti Cake with Rainbow Buttercream

Are all things rainbow still trending? Well, sure!

So how about a funfetti cake with rainbow icing? 

                       

This is a great alternative to a rainbow layer cake, and it's a cake walk to make. 😉 

Like most things baking / decorating, it's all in the prep work... 

For the funfetti cake, I used this recipe (again!) and added a cupful of cake confetti.  

(Depending on how large your cake pans are, and how tall you want the cake, you may need to double the recipe.)

For the rainbow icing, make a batch of your favourite buttercream (recipe here) or swiss meringue buttercream (recipe here). Make a double batch for a large cake.
Divide it into 5 bowls, and add gel food colours.
I generally use the electric colours (electric blue, pink, etc) because they have a cool undertone, and don't accentuate the butter's inherent yellow.

Put the icing into 5 disposable icing bags with the tips cut off, and pipe concentric rings of the different colours between each layer of sponge. 

If you have any icing leftover, tie the ends of the bags off with rubber bands and freeze until you have use for it.  (Now, isn't that a good tip?!)

I covered the outside of the cake in plain buttercream, with a pink drip, because I wanted the rainbow effect to be a surprise-inside. Such a sweet surprise 😋

Happy baking!
