Ingredients Notes

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

Butter – Using real butter gives these brownies a rich, decadent flavor. You can use salted or unsalted butter, but if using salted, reduce the added salt slightly.

Granulated Sugar – This provides the perfect sweetness and helps create that signature crackly top. Don’t reduce the sugar, or you’ll lose the classic texture!

Cocoa Powder – A good-quality unsweetened cocoa powder is key for deep chocolate flavor. Dutch-processed cocoa will give a darker, more intense taste, while natural cocoa results in a lighter flavor.

Eggs – Using fresh, room-temperature eggs helps create a smooth, well-mixed batter and gives structure to the brownies.

All-Purpose Flour – The small amount of flour in this recipe keeps the brownies fudgy rather than cakey. Be sure to measure accurately—too much flour can make them dry.

Vanilla Extract – This enhances the chocolate flavor and adds a hint of warmth to the brownies. Use pure vanilla for the best taste.

Powdered Sugar for Frosting – The light, creamy frosting on these brownies is a must! Powdered sugar ensures a smooth texture, blending perfectly with the butter and cocoa powder.

How To Make These Lunchroom Ladies Brownies

Making these brownies is as easy as it gets! Just follow these simple steps for guaranteed delicious results.

Start by preheating your oven to 350°F and greasing a large 9x13-inch baking pan or lining it with parchment paper. This ensures your brownies won’t stick and makes cleanup easier.

In a large mixing bowl, melt the butter and stir in the cocoa powder until smooth. This step helps bloom the cocoa, intensifying its chocolatey richness.

Next, whisk in the sugar and eggs, mixing well until fully combined. The batter should look glossy and thick.

Add the vanilla extract and gently fold in the flour and salt, mixing just until no streaks remain. Overmixing at this stage can lead to tough brownies, so stir only until combined.

Pour the batter into the prepared pan and spread it evenly. Bake for about 25-30 minutes, or until a toothpick inserted in the center comes out with a few moist crumbs. Don’t overbake, or they’ll lose their fudginess!

While the brownies are cooling, prepare the frosting. In a separate bowl, whisk together the melted butter, cocoa powder, powdered sugar, milk, and vanilla extract until smooth. Spread the frosting over the warm brownies, letting it slightly melt into the surface for a perfect finish.

Allow the brownies to cool completely before cutting. For the cleanest cuts, chill them in the fridge for about 30 minutes before slicing.

Storage Options

If you somehow have leftovers, these brownies store beautifully!

At room temperature, keep them in an airtight container for up to 3 days. If you want them to last longer, store them in the refrigerator for up to a week—just bring them to room temperature before serving for the best texture.

For longer storage, freeze individual brownie squares in a sealed container or wrapped in plastic wrap. They’ll stay fresh for up to 3 months. When ready to eat, simply thaw at room temperature or microwave for a few seconds for a warm, gooey treat.

Variations and Substitutions

This recipe is a classic, but there are plenty of ways to customize it to fit your taste!

Add nuts – Stir in ½ cup of chopped walnuts or pecans for a little crunch and extra richness.

Make them extra chocolatey – Fold in ½ cup of chocolate chips into the batter before baking for an even deeper chocolate flavor.

Try a different frosting – If you want something extra special, swap the classic frosting for a peanut butter glaze or cream cheese icing.

Use brown sugar – For a slightly more caramel-like flavor, replace half of the granulated sugar with brown sugar. This gives the brownies a bit of chewiness and added depth.

Go gluten-free – Use a 1:1 gluten-free flour blend in place of regular flour. These brownies are naturally low in flour, so they adapt well to gluten-free substitutions.
