When I make cupcakes, my default position for the icing is to use Butter Frosting. I think is the partly because it’s really easy to make, but probably mostly because it’s so delicious!
Here is the basic recipe that I use for 2 dozen cupcakes.
150gm softened butter
3 C Icing Sugar
1-2 T hot water
I beat the butter for a short while in my mixer, then add the icing sugar 1 cup at a time. Be sure to really beat this (2-3 minutes minimum). Add 1 tablespoon of water initially, then add more water if necessary. Add your food coloring and flavour. You are looking for a ‘fluffy’ consistency. It will be harder to pipe if it is too stiff.
If you want to be a little creative, you can divide the mixture in half and make two different colors. Carefully place the frosting on only 1 side of the piping bag, then fill up the other side with the other color. This can create a really great effect, as you can see with these cupcakes.
