Ingredients
(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)
For the brownies:
1 cup melted butter
1/2 cup unsweetened cocoa powder
2 cups all-purpose flour
2 cups granulated sugar
1/2 teaspoon salt
4 large eggs
3 tablespoons vanilla extract
For the frosting:
1/4 cup melted butter
1/4 cup milk
3 cups powdered sugar
1/4 cup unsweetened cocoa powder
1 tablespoon vanilla extract
Directions
Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking pan or line it with parchment paper for easier removal.
In a large mixing bowl, whisk together the melted butter and unsweetened cocoa powder until smooth and glossy.
Add the flour, granulated sugar, and salt. Stir until the dry ingredients are mostly incorporated.
Add the eggs and vanilla extract. Mix until the batter is smooth and fully combined. Do not overmix.
Spread the batter evenly into the prepared baking pan.
Bake for 25 minutes, or until the brownies are set and a toothpick inserted near the center comes out with a few moist crumbs.
While the brownies are baking, make the frosting. In a medium bowl, whisk together the melted butter, milk, powdered sugar, cocoa powder, and vanilla extract until smooth. The frosting should be spreadable and free of lumps.
Once the brownies come out of the oven, let them cool for a few minutes so they are still warm but not piping hot.
Spread the frosting evenly over the warm brownies. The warmth helps the frosting settle into a smooth, classic finish.
Let the brownies cool completely before slicing into bars and serving.
You can easily change this recipe to fit your taste while keeping the vintage feel. Add 1 cup chopped walnuts or pecans to the batter for crunch. Stir in 1/2 cup chocolate chips for a richer brownie. For a slightly deeper flavor, use a pinch of espresso powder in the batter or frosting. You can also add a light sprinkle of sea salt on top of the frosting to balance the sweetness. For cleaner slices and a more set frosting, chill the brownies briefly before cutting.
Storage/Reheating
Store the brownies in an airtight container at room temperature for up to 3 days. For longer storage, keep them in the refrigerator for up to 1 week. Let refrigerated brownies come to room temperature before serving for the best texture.
To freeze, place the cut brownies in a freezer-safe container with parchment between the layers and freeze for up to 2 months. Thaw overnight in the refrigerator or at room temperature for a few hours.
For reheating, warm an individual brownie in the microwave for about 8 to 10 seconds. This makes it soft and slightly gooey again without drying it out.
FAQs
Why are they called lunch lady brownies?
They are called lunch lady brownies because they are inspired by the rich, frosted brownies often served in school cafeterias many years ago.
What makes these brownies different from regular brownies?
These brownies are known for their soft, fudgy texture and their signature chocolate frosting spread over the top while the brownies are still warm.
Can I use Dutch-process cocoa powder?
Yes, but the flavor may be slightly smoother and less sharp than with regular unsweetened cocoa powder. Either can work in this recipe.
Can I make these brownies ahead of time?
Yes. These brownies are great for making a day in advance since the frosting sets nicely and the flavor stays rich and chocolatey.
Do I need to frost the brownies while they are warm?
Yes, that is the best way to get the classic finish. The warm brownies help the frosting spread smoothly and settle on top.
Can I use a different pan size?
A 9×13-inch pan works best for the classic thickness. Using a smaller pan will make thicker brownies and may require extra baking time.
How do I know when the brownies are done?
The edges should be set, and a toothpick inserted near the center should come out with a few moist crumbs, not wet batter.
Can I add nuts to this recipe?
Yes. Chopped walnuts or pecans work very well and add a nice crunch to the soft brownie texture.
Why did my frosting turn out too thick?
If the frosting seems too thick, add a small splash of milk, one teaspoon at a time, until it reaches a smooth spreadable consistency.
Can I freeze frosted brownies?
Yes. Frosted brownies freeze well. Place them in layers separated by parchment paper in a freezer-safe container and thaw before serving.
