Brownies
- 1 box brownie mix (usually 16–18 ounces)
- 6 tablespoons butter
- 1/3 cup milk
Frosting
- 1 1/4 cups granulated sugar
- 1 teaspoon vanilla extract
- 1/2 teaspoon coarse kosher salt
- 1 cup semi-sweet chocolate chips
- rainbow sprinkles
- Make the brownies: Prepare and bake the brownies according to the directions on the box, using a 9×13 inch or slightly smaller rectangular pan. Once baked, allow the brownies to cool for about an hour before frosting to ensure the frosting sets properly without melting.
- Make the frosting: In a small saucepan over medium heat, melt the butter. Add the milk, granulated sugar, vanilla extract, and coarse kosher salt. Bring this mixture to a consistent rolling boil and cook for exactly 45 seconds to form a glossy, smooth frosting base. Use a timer to avoid overcooking.
- Mix in the chocolate: Remove the saucepan from heat and immediately stir in the semi-sweet chocolate chips until fully melted and combined. If the frosting has lumps, whisk vigorously for about a minute to smooth it out.
- Frost the brownies: Quickly pour the warm chocolate frosting evenly over the cooled brownies and spread it out smoothly. Immediately sprinkle with rainbow sprinkles before the frosting begins to set, as it will start to harden very quickly.
- Rest and serve: Allow the frosting to rest and set for 15 to 30 minutes depending on desired slice cleanliness. Once set, cut the brownies into squares, serve, and enjoy your festive party treat!
Notes
- Note 1: Using a 9×13 inch or slightly smaller rectangular pan provides the ideal brownie thickness for this frosting technique.
- Note 2: Pour and spread the frosting quickly as it sets immediately to ensure a smooth surface and even coverage.
