Gooey, chocolatey and melty, this is the best chocolate frosting recipe for Texas sheet cakes and brownies. It’s so soft and melty, you’ll feel like you’re eating candy.


  • 1/2 cup salted butter
  • 1/3 cup unsweetened cocoa powder
  • 1/3 cup buttermilk
  • 3 cups powdered sugar
  • 1 teaspoon vanilla extract


  • Melt butter in a medium-sized saucepan over low heat. Whisk in cocoa powder, then pour in buttermilk. Increase heat to medium high and bring to a simmer, whisking constantly.
  • Once the mixture is simmering, remove from the heat and whisk in powdered sugar and vanilla until smooth. Pour over cake or brownies to cover. Use a rubber spatula to smooth out and spread if needed. Cake or brownies can still be warm.
