Lunch Lady Brownies are rich, fudgy, and topped with creamy homemade chocolate frosting. An easy one bowl cafeteria classic ready in 40 minutes. Makes 24.
Preheat oven to 350F. Prepare a 9×13 baking dish with either aluminum foil or parchment paper. Spray with non-stick cooking spray. Set aside.
Prepare The Brownies
In a large bowl, combine the cocoa powder and melted butter. Stir until smooth.
Add the sugar, eggs, and vanilla. Stir to combine.
Gently fold in the flour and mix just until the batter comes together. Do not over mix or the brownies will be tough.
Bake at 350F for 25-30 minutes or until the middle is just set and a toothpick comes out clean with maybe a crumb or two. You don't want to over bake the brownies or they will be dry.
Remove from the oven when done and let cool for 10 minutes.
Prepare The Frosting
While the brownies are baking prepare the frosting. You can use the same bowl as the brownie batter!
Mix together the softened butter, cocoa powder, and powdered sugar.
Stir in the evaporated milk until the frosting is smooth.
Frost The Brownies
When the 10 minutes of cooling time is up, spread the frosting in a single even layer over the brownies. I like to us an off set spatula.
The frosting will "melt" onto the brownies and form and nice crust on top.
Let cool completely before slicing and serving.
Notes
Don't overmix the batter once the flour goes in, or the brownies get tough.
Don't overbake. Pull them when a toothpick comes out with just a crumb or two.
Measure the flour by fluffing, spooning, and leveling so the brownies stay fudgy, not dry.
Let the brownies cool 10 minutes before frosting so it melts into a crust instead of sliding off.
Line the pan with parchment for easy removal and clean cuts.
Add sprinkles for a bit of fun, or serve warm with vanilla ice cream.
