Ingredients Notes

The beauty of this recipe is its simplicity, but each ingredient plays a key role in making these brownies just right.

Butter – The foundation of these brownies is melted butter, which gives them a rich flavor and contributes to that perfect fudgy texture. For the best results, use real, unsalted butter instead of margarine.

Cocoa Powder – Instead of using melted chocolate, these brownies get their deep flavor from unsweetened cocoa powder. This keeps the texture lighter while still delivering an intense chocolate taste.

Granulated Sugar – A generous amount of sugar not only sweetens the brownies but also helps create the signature crackly top. Don’t skimp on this!

Eggs – Eggs provide structure and moisture, keeping the brownies from being too dry or crumbly. Make sure to whisk them well before adding them to the batter.

All-Purpose Flour – The small amount of flour used in this recipe keeps the brownies tender. Be careful not to overmix the batter once you add the flour, as this can make them too dense.

How to Make These Lunchroom Ladies Brownies

Making these brownies is as easy as it gets! Here’s how to bring them to life:

Start by preheating your oven to 350°F and greasing a 9x13-inch baking pan. You can also line it with parchment paper for easy removal.

In a large mixing bowl, whisk together melted butter and cocoa powder until smooth. This step ensures that the cocoa powder is evenly distributed for that rich chocolate flavor.

Next, stir in the sugar and eggs, mixing well until fully combined. The batter will start to look glossy and thick—this is a good sign that the sugar is dissolving properly.

Gently fold in the flour and salt, being careful not to overmix. Just stir until the flour disappears into the batter; overmixing can lead to tougher brownies.

Pour the batter into your prepared pan, spreading it evenly. Bake for 25-30 minutes, or until a toothpick inserted in the center comes out with a few moist crumbs. You don’t want to overbake—these brownies should stay soft and fudgy inside.

Let the brownies cool completely before slicing. This allows them to set properly, giving you perfect, clean cuts.

Storage Options

If you manage to have leftovers (which is rare!), these brownies store beautifully.

At room temperature, keep them in an airtight container for up to 4 days. They stay soft and fudgy, making them the perfect make-ahead treat.

For longer storage, place them in an airtight container and refrigerate for up to a week. Let them sit at room temperature for a few minutes before serving for the best texture.

They also freeze well! Wrap individual squares in plastic wrap and store them in a freezer-safe bag for up to 3 months. Just thaw at room temperature when you’re ready to enjoy.

Variations and Substitutions

One of the best things about this recipe is how adaptable it is. Here are a few fun variations:

Want an extra chocolatey kick? Stir in a handful of chocolate chips before baking for melty pockets of goodness.

For a nutty crunch, add chopped walnuts or pecans to the batter. The slight crunch contrasts beautifully with the fudgy texture.

If you love frosted brownies, whip up a simple chocolate frosting with butter, cocoa powder, powdered sugar, and milk. Spread it on top once the brownies have cooled.

Looking to cut back on sugar? Swap out some of the granulated sugar for a sugar substitute, though keep in mind this may slightly affect the crackly top.

Gluten-free? Substitute a 1:1 gluten-free flour blend for the all-purpose flour, and you’ll still get amazing results.

Experiment with flavors and toppings to make these brownies your own. No matter how you tweak them, you can’t go wrong with this classic recipe!
