Iconic Texas Sheet Cake just wouldn't be the same without a rich, chocolate icing. The fun surprise to this frosting? Dr. Pepper!
Cook butter and chocolate in a medium saucepan over medium-low heat, whisking often, until melted and smooth.
Remove from heat, and whisk in milk and soft drink until blended. Gradually sift in powdered sugar, whisking constantly. Whisk in vanilla. Use immediately.
