American Buttercream: Recipe adapted from Craftsy class Icing on the Cake: The Ultimate Frosting Toolkit
sticks of butter
softened at room temperature
of confectioner's sugar
drops of food coloring gel
In a stand mixer, mix the butter until smooth.
Add the confectioner's sugar slowly to incorporate.
Slowly add milk and vanilla while mixing.
Mix all ingredients in stand mixer for 3 - 4 minutes, until buttercream is light, airy and smooth. (Note: The Craftsy video mentioned above was really helpful in understanding how to know when the buttercream was done, but it's certainly not necessary.)
Remove bowl from stand mixer and fold in 3 -4 drops of food coloring gel (optional).
