Step 1

In a large mixing bowl with a handheld electric mixer or the bowl of a stand mixer with the paddle attachment, beat the butter on medium speed for about 30 seconds until creamy. Add the room temperature cream cheese, vanilla, and salt. Beat together on medium speed for about about 2 minutes until very well combined.

Step 2

With the mixer on low speed, add 4 cups of the powdered sugar in a cup at a time. Mix until combined. If you would like a thicker frosting, use all 6 cups.

Step 3

Scrape down the sides and bottom of bowl. Beat on medium-low speed for 1 minute or until nice and fluffy. Transfer to a piping bag fitted with a decorative tip or spread over your favorite cake. This recipe makes enough frosting for 2 dozen cupcakes, 1 (8-inch) two-layer cake, or a 13x9-inch sheet cake.
