Step 1

In the bowl of a stand mixer with a paddle attachment or in a large mixing bowl with an electric hand mixer, beat the butter until smooth, about 2 minutes.

Step 2

Gradually add the powdered sugar, about a cup at a time, and mix starting on low speed gradually increasing to medium, until all the powdered sugar is mixed in.

Step 3

Add 2 tablespoons of milk and vanilla and beat on medium speed for 3-4 minutes, until everything is well combined. Scrape the bowl as needed.

Step 4

If the frosting seems too thick, you can add more milk, 1 tablespoon at a time. If the frosting is too thin and runny, simply add more powdered sugar, 1/2 cup at a time until the desired consistency is reached.

Step 5

Pipe onto cupcakes, spread on a cake or anywhere else you'd like. Enjoy!

Step 6

You can make the frosting up to 2 days in advance. Store in the refrigerator until ready to use, then bring it to room temperature before using. It can also be frozen for up to 3 months.
