Lunchroom Ladies Brownies

 

Ingredients

For the Brownies:


1 cup (2 sticks) unsalted butter, melted and slightly cooled

½ cup unsweetened cocoa powder (Dutch-process or natural both work)

2 cups granulated sugar

4 large eggs, at room temperature

4 teaspoons pure vanilla extract

2 cups all-purpose flour

For the Icing:


¼ cup (½ stick) unsalted butter, softened

¼ cup whole milk

¼ cup unsweetened cocoa powder

3 cups powdered sugar, sifted

Note: Do not substitute margarine—it affects texture and flavor.


Instructions

Prep & Preheat

Heat your oven to 350°F (175°C). Generously grease a 9×13-inch baking pan, then line it with a parchment or foil sling (leaving overhang on two sides for easy removal).

Make the Batter

In a large bowl, whisk together the melted butter and sugar until well combined. Add the eggs and vanilla, stirring until smooth and glossy.

Sift or whisk in the cocoa powder and flour, mixing just until no dry streaks remain. Do not overmix—the batter will be very thick, almost like stiff cookie dough.

Bake to Fudgy Perfection

Scrape the batter into the prepared pan. Use a rubber spatula or wet fingers to press and smooth it into an even layer (it’s sticky—be patient!).

Bake for 20–25 minutes, or until a toothpick inserted near the center comes out with a few moist crumbs (not wet batter). When in doubt, underbake slightly—these brownies set as they cool.

Prepare the Icing

As soon as the brownies come out of the oven, start the icing. In a medium bowl, beat the softened butter, milk, and cocoa powder until smooth. Gradually add the powdered sugar, mixing until creamy and pourable. If too thick, add 1 tsp more milk; if too thin, add a bit more sugar.

Ice While Warm

Let the brownies cool in the pan for 10–15 minutes—they should still be quite warm. Pour the icing evenly over the surface. It will spread and sink slightly into the warm crumb, creating that signature lunchroom finish.

Cool Completely Before Cutting

Allow the brownies to cool fully in the pan (about 1–2 hours) so the icing sets. Lift out using the parchment sling, then slice into squares with a sharp knife (wipe between cuts for clean edges).

Serving Suggestions

Serve with a cold glass of milk or a scoop of vanilla ice cream

Pack in lunchboxes or gift boxes lined with parchment

Pair with coffee for an afternoon pick-me-up

Store extras in an airtight container—they stay moist for days!

Frequently Asked Questions

Can I use a different pan size?

Yes—a 9×9-inch pan will yield thicker brownies; bake 25–30 minutes. Avoid glass pans if possible; metal conducts heat more evenly.


Can I make these gluten-free?

Yes! Substitute a 1:1 gluten-free flour blend (like Bob’s Red Mill) for the all-purpose flour.


Why is the batter so thick?

That’s intentional! Less liquid = denser, fudgier texture—the hallmark of old-school cafeteria brownies.


Can I skip the icing?

You can, but you’ll miss the nostalgic touch. The icing adds sweetness and that iconic crackly top.
