Lunchroom Ladies Brownies: The Fudgy, School-Cafeteria Classic That Tastes Like Childhood

For the Chocolate Icing:

¼ cup (½ stick / 56g) butter, softened

ÂĽ cup (60ml) whole milk (or half-and-half for richness)

ÂĽ cup (20g) unsweetened cocoa powder

3 cups (360g) powdered sugar, sifted

That’s it.

No leavener. No nuts. No mixer required.

Just real food, mixed into magic.

🔥 How to Make Them: Step-by-Step, Soul-Warmingly

Let’s bake this like we’re honoring a classic—one thick spoonful at a time.

Step 1: Preheat & Prep

Preheat oven to 350°F (175°C).

Grease a 9×13-inch baking dish and line with parchment paper or foil, leaving overhang for easy lift-out.

Step 2: Mix the Wet Ingredients

In a large bowl:

Whisk together melted butter and granulated sugar until smooth.

Add eggs one at a time, mixing well after each.

Stir in vanilla extract.

👉 Batter will look grainy at first—keep stirring. It comes together.

Step 3: Add Dry Ingredients

Sift in cocoa powder and flour (and salt, if using).

Stir gently with a spatula until just combined.

⚠️ Do NOT overmix! Overmixing = tough brownies.

Batter will be thick, glossy, and fudge-like—that’s perfect.

Step 4: Bake to Fudgy Perfection

Pour batter into prepared pan.

Smooth the top as best you can (it’s okay if it’s uneven).

Bake 20–25 minutes, until a toothpick comes out with a few moist crumbs (not wet batter).

💡 Pro tip: Slightly underbake—these brownies firm up as they cool and stay fudgy longer.

Step 5: Make the Icing While Warm

As soon as brownies come out:

Let cool 10–15 minutes (still very warm—this helps the icing set evenly).

In a bowl, mix softened butter, milk, cocoa powder, and powdered sugar until smooth and pourable.

Step 6: Ice & Cool

Pour icing over warm brownies.

Use a spatula to spread gently—it will sink slightly and create that classic cafeteria sheen.

Let cool completely before slicing (~1–2 hours).
