Step 1

Whip the room temperature unsalted butter on a medium high speed with a whisk attachment of a stand mixer or hand mixer for 5-7 minutes. The butter should lighten in color as you incorporate air into it.

Step 2

Add in the vanilla extract and salt, and mix on a low speed until incorporated.

Step 3

Slowly mix in the sweetened condensed milk, adding ¼ of the can at a time, mixing on a medium speed.

Step 4

Scrape down the sides and bottom of the bowl with a rubber spatula throughout the process. The sweetened condensed milk sometimes pools at the bottom of the bowl, so be sure to scrape all the way to the bottom.

Step 5

If you frosting is broken or not stiff enough, you can add in powdered sugar, 1/2 cup at a time to thicken it and bring it together.

Step 6

Use to frost layer cakes, pipe on cupcakes, or even to ice cookies. It tastes amazing on just about everything!!
