Before You Get Started

  • Cool completely before frosting. If you frost warm brownies the butter in the frosting will melt and the finish will be shiny and runny.
  • Store at room temperature for up to 3 days in an airtight container. For longer storage refrigerate or freeze.

How to make Chocolate Frosted Brownies

  1. Brown the butter: Add butter to a medium saucepan and cook over medium heat, stirring occasionally, until it turns a light brown or caramel color, about 5–10 minutes. Watch closely so it doesn’t burn.

How to make brownie frosting:

  1. Beat the butter: Place softened butter in a stand mixer fitted with the whisk (or use a handheld mixer) and beat until light and fluffy.
  2. Add the remaining ingredients: Add unsweetened cocoa powder, confectioners’ sugar, milk (use dairy-free milk if preferred), and vanilla. Beat until smooth and creamy. If the frosting is too thick, add a little more milk. If it’s too thin, add more powdered sugar.
  3. Set aside: Reserve the chocolate buttercream until the brownies are fully cooled, then spread evenly over the pan.
