These Lunchroom Ladies Brownies are thick, fudgy, and topped with a rich chocolate frosting that brings back nostalgic cafeteria memories. With their crinkly tops, deep cocoa flavor, and chewy texture, they’re the ultimate old-fashioned brownie treat.

Ingredients

For the Brownies:

1 cup unsalted butter, melted

1/2 cup unsweetened cocoa powder

2 cups granulated sugar

4 large eggs

1 tablespoon vanilla extract

1 1/2 cups all-purpose flour

1/2 teaspoon salt

1/2 teaspoon baking powder

1 cup semi-sweet chocolate chips (optional)

For the Classic Frosting:

1/4 cup unsalted butter, softened

1/4 cup unsweetened cocoa powder

2 cups powdered sugar

1/4 cup milk

1 teaspoon vanilla extract

Instructions

  1. Preheat oven to 350°F (175°C). Grease or line a 9×13-inch baking pan with parchment paper.
  2. In a large bowl, whisk melted butter and cocoa powder until smooth. Stir in sugar until fully combined.
  3. Add eggs one at a time, mixing well after each addition, then stir in vanilla extract.
  4. In a separate bowl, whisk together flour, salt, and baking powder. Gradually fold dry ingredients into the wet mixture until just combined. Avoid overmixing.
  5. Fold in chocolate chips if using, then spread batter evenly in the prepared pan.
  6. Bake for 25–30 minutes, or until a toothpick inserted into the center comes out with moist crumbs. Let cool completely before frosting.
  7. For the Frosting: In a bowl, beat butter and cocoa powder together until creamy. Alternate adding powdered sugar and milk until smooth and spreadable. Stir in vanilla extract.
  8. Spread frosting evenly over cooled brownies. Let set for 10 minutes before slicing into squares.

Notes

Use dark cocoa powder for a richer chocolate flavor.

Add a swirl of peanut butter or caramel before baking for variation.

Top with mini chocolate chips or sprinkles for extra texture.

Chill brownies before slicing for neat, clean edges.

Store at room temperature for 3 days or freeze for up to 2 months.
