To make it funfetti, add 1/2 cup sprinkles (or rainbow chip funfetti)

Vanilla Buttercream

3 sticks (1 1/2 cups) unsalted butter

Pinch of salt

1 Tablespoon pure vanilla extract

1/4 cup heavy cream (plus more if needed)

7-8 cups powdered sugar

In the bowl of a stand mixer fitted with a paddle attachment, beat the butter on medium speed until it's light and fluffy.

Add the salt, vanilla, and heavy cream and beat again until thoroughly combined. Scrape down the sides of the bowl.

With the mixer on low speed, add the powdered sugar about 1/2 cup at a time.  Add a little more heavy cream if needed, then flip the mixer to high speed and beat until the buttercream is lighter in color and texture, about 2 minutes.
