Step 1

In a stand mixer fitted with the paddle attachment, whip the butter on high until it’s fluffy and light (almost white in color), 5-6 minutes, scraping down the bowl and paddle a few times in between. Turn the mixer to low and add the powdered sugar a few cups at a time, scraping down the bowl and paddle after each interval. Add the vanilla.

Step 2

With the mixer still on low, add the salted caramel. Add a pinch of salt, increase the speed to medium, and mix for 2 full minutes.
