TOTAL TIME: 15 minutes
1 cup (2 sticks) super soft butter
3-4 cups powdered sugar
Splash of room temperature heavy cream
Lemon zest (optional)
Begin by beating your softened butter on high for 5 minutes. Beating it for a long period of time ensures that it is fluffy and smooth.
Add in the powdered sugar half a cup at a time and beat until smooth. You can add more/less depending on how sweet you want it.
After all of the sugar is added, continue to beat for another 2 minutes until everything is smooth.
Add in vanilla extract and mix. If desired, add in lemon zest and sprinkles.
