Make sure your butter and cream cheese is room temperature. If the cream is even a little cold, the frosting can split.
1 cup Unsalted butter, 8 oz Cream cheese
In a large bowl, sift the powdered sugar and cocoa powder together. Set aside
1 3/4 cup Powdered sugar, 1/3 cup Unsweetened cocoa powder
Using a mixer, beat the butter on high speed for 2 minutes. Scrape the bowl using a baking rubber spatula. Add in the cream cheese and beat on high speed for 1 minute.
Add in half of the powdered sugar/cocoa powder and mix on low until just combined. Add in the rest of the powdered sugar and mix.
Scrape the bowl and add in the vanilla. Beat on high speed until creamy. Then, it is ready to use!
1 tsp Pure vanilla extract
