There’s something magical about the brownies we remember from childhood—those perfectly fudgy, chocolate-packed squares that were a highlight of school lunches. Lunchroom Ladies Brownies are the ultimate nostalgic dessert, bringing back memories of cafeteria trays, plastic milk cartons, and that one sweet treat that made school lunches special.
Ingredients
For the Brownies:
1 cup unsalted butter, melted
½ cup unsweetened cocoa powder
2 cups granulated sugar
4 large eggs
1 tablespoon vanilla extract
1½ cups all-purpose flour
½ teaspoon salt
½ teaspoon baking powder
1 cup semi-sweet chocolate chips (optional, but highly recommended)
For the Classic Frosting:
¼ cup unsalted butter, softened
¼ cup unsweetened cocoa powder
2 cups powdered sugar
¼ cup milk
1 teaspoon vanilla extract
Instructions
1. Preheat & Prepare
Preheat your oven to 350°F (175°C).
Grease a 9×13-inch baking pan or line it with parchment paper for easy removal.
2. Make the Brownie Batter
In a large mixing bowl, whisk together melted butter and cocoa powder until smooth.
Add in sugar, mixing until combined.
Beat in the eggs one at a time, ensuring each is fully incorporated before adding the next.
Stir in vanilla extract.
In a separate bowl, whisk together flour, salt, and baking powder.
Gradually fold the dry ingredients into the wet mixture, stirring just until combined.
If using, gently fold in the chocolate chips.
3. Bake to Perfection
Pour the batter into the prepared baking pan, smoothing it out evenly.
Bake for 25-30 minutes, or until a toothpick inserted in the center comes out with a few moist crumbs (not wet batter).
Remove from the oven and let cool completely before frosting.
4. Make the Frosting
In a mixing bowl, beat together softened butter and cocoa powder.
Gradually add in powdered sugar, alternating with milk, until smooth and spreadable.
Stir in vanilla extract for extra depth of flavor.
5. Frost & Serve
Spread the frosting over the cooled brownies.
Let the frosting set for about 10 minutes before slicing into squares.
Enjoy with a glass of milk for the full nostalgic experience!
Notes
Tips for the Best Brownies
Don’t overmix: Stir the batter just until combined to keep the brownies tender.
Use quality cocoa powder: Since cocoa is the star, use a high-quality brand for the richest flavor.
Let them cool before frosting: If you frost too soon, the icing will melt into the brownies.
Chill for cleaner cuts: If you want perfect, bakery-style slices, chill the brownies in the fridge before cutting.
