Preheat the oven to 350 degrees F. Line a 12-cup muffin tin with liners. Depending on how many muffin tins you have, you may need to work in batches. Set aside.
Add 2 cups of the powdered sugar and beat on low speed until well combined.
Frost the cupcakes however you like. I'm partial to piping roses with a Wilton 1M piping tip and piping bag.
