Combine the butter and cream cheese in a large bowl. Using an electric mixer or a stand mixer, beat until creamy.
Add vanilla extract and stir well to combine.
Whisk powdered sugar and cocoa powder together until combined.
Add the powder mixer into the cream cheese mixture and beat until well-incorporated into the frosting, being sure to scrape the sides and bottom of the bowl so that all ingredients are well-combined.
Frost completely cooled cupcakes. I made 6 jumbo cupcakes and used way more frosting than usual for the hubby. LOL
