The ingredients to make funfetti buttercream frosting.How to Make Funfetti Buttercream Frosting

The keys to making this recipe are in making sure your butter is softened, and you have a quality mixer to do the bulk of the work.  To create a smooth and creamy texture, you need to blend together your sugar and butter until it is free from lumps.

A hand mixer or stand mixer can work in this case, but it definitely is a need.  Hand mixing this frosting typically won’t give you the results you are looking for on a cupcake.  

Another important part of making funfetti frosting is to sift your dry ingredients.  While this is not necessary, it makes a huge difference in how smooth the resulting frosting can be on your cupcake.

Yes!  This is one of those parts of your party that you can definitely make in advance and store in the refrigerator.  While some have gone so far as to freeze, it is often more difficult to maintain that smooth texture. 

You can place this in an airtight container in the refrigerator for up to one week.  When ready to use, make sure to place on the counter to come to room temperature before icing your cupcakes or cake. 

Note: Make sure you are storing in a secure airtight container.  Frosting can pick up the flavors of things around it very easily, so this is one time you should avoid placing near the chopped onions or leftover taco meat in the refrigerator. We place ours in a smaller fridge dedicated to baked cakes and cupcakes to avoid this from happening!
