In the bowl of a standing mixer or handheld mixer, beat butter, vanilla extract, and spices.
Slowly add in ¼ cup of powdered sugar at a time until it reaches your desired consistency.
If the buttercream is too thick, you can add ½ tablespoon of milk of choice at a time, thinning it out as much as you'd like. If buttercream is too thin, add in more powdered sugar ¼ cup at a time.
Use it to frost your favorite cakes and cupcakes!
