Welcome to howtocookthat I am Ann Reardon and this is an easy buttercream rainbow cake.
Firstly you need to make up your buttercream, the recipe for that is on the blog howtocookthat.net
there is a link in the description below this video.
All you do is add the butter and icing sugar, stir well then and whisk for about 5 minutes
on high speed until it is pale and fluffy.
Add a tiny bit of milk but not much because you are going to be adding a fair bit of liquid
colour to get those bright rainbow colors.
Split two thirds of your frosting into 5 bowls and add your chosen colours to each bowl.
Now to get the really bright colours here you will have to add quite a bit of liquid
colour, so add it a tablespoon at a time until you get a colour you are happy with.
Then take each colour and place it into a plastic bag push it down into the corner and
twist the top to stop the icing from oozing out the top when you squeeze the bag.
Take half of the remaining uncoloured frosting and put that in a bag also.
Put your bottom layer of cake onto a plate and pipe a cirlce of uncoloured frosting around
the edge.
Then you can either put buttercream in the middle as well or you can use a filling.
Here I am using home made lemon curd.
Having the layer of buttercream around the edge helps contain the filling and stops it
from oozing out the side of the cake and effecting the decorating.
Repeat this with the next layer of cake as well.
Then take a palette knife and smooth the buttercream that is in the joins adding more if necessary.
So you have a nice flat finish.
Place a thin layer of buttercream on the top of your cake just to level it out.
Cut the corner off each of your coloured bags and then starting at the bottom pipe of blob
of each colour repeating them when you get to the top going through a pattern.
Take a spoon that's been dipped in hot water and push it sort of half way along the blob
and drag it across the cake.
So just push it in and drag it across.
Keep doing that all the way up the cake.
Then for your next row of blobs you need to pipe the colour that was just above the one
that you are currently doing on the previous row.
And continue in this pattern the whole way up.
Use your spoon to spread them out and keep piping and around the cake.
On the top of the cake pipe blobs in a circle shape smearing them one at a time.
Until you have filled in all of the gaps.
