Instructions

Make Brownies

Arrange an oven rack in the center position. Preheat oven to 350ºF (177ºC). Line a 9X13-inch baking dish with parchment paper.
In a saucepan, melt the butter (1 cup), cocoa powder (1/2 cup), and decaf coffee crystals (1/2 teaspoon) over medium-low heat, until smooth and shiny. Remove from heat.
Let the mixture cool for 5–10 minutes, or until it's warm but no longer hot to the touch (this prevents the eggs from cooking when added).
Transfer the cooled mixture to a large mixing bowl. Add sugar (2 cups), eggs (4), and vanilla (1 tablespoon). Beat with an electric mixer on medium speed for 2–3 minutes, until lightened in color and slightly thickened.
Add the flour (1 1/2 cups) and mix on low speed just until combined. Fold in chopped nuts (1 cup), if using.
Pour the batter into the prepared baking dish and spread evenly. Bake for 20–22 minutes, or until a toothpick inserted in the center comes out with a few moist crumbs. Do not overbake.

Make Icing

While the brownies bake, combine the softened butter (1/4 cup), milk (1/4 cup), cocoa powder (1/4 cup), vanilla extract (1 teaspoon), powdered sugar (3 cups), and salt (dash) in a mixing bowl. Whisk until smooth, or use an electric mixer on low speed.
Pour the icing over the warm (not hot) brownies and spread evenly to cover.

Notes

Getting that glossy, crackly frosting. For that classic lunchroom shine, spread the icing over brownies that are warm but not steaming hot. The warmth melts the sugar slightly, and as the brownies cool, the sugar recrystallizes, creating that smooth, glossy finish with a soft little crackle on top.
Don’t chase a clean toothpick. A clean toothpick usually means overbaked brownies. Instead, look for a few moist crumbs, a slightly matte surface, and tiny bubbles across the top. The center should have a gentle spring when pressed. That’s your signal they’ll stay fudgy instead of drying out.
Use a metal pan for the most even bake. Metal 9×13 pans bake more evenly and prevent overdone edges. Glass pans hold heat longer, which can cause the sides to overbake before the center is set — especially with thick brownies like these.
Want thin cafeteria-style brownies? If you remember thinner school lunch brownies, bake this batter in a 10×15-inch jelly roll pan instead. Start checking around 15–18 minutes, since thinner brownies cook faster and can dry out quickly.
Choose your cocoa wisely. Natural unsweetened cocoa (like Hershey’s) delivers that classic, nostalgic cafeteria flavor. Dutch-process cocoa works too, but it produces a smoother, slightly darker, less “lunchroom” taste. Both are good — they’re just different.
Keep them fudgy, not cakey. Once you add the flour, mix just until it disappears. Overmixing develops gluten and shifts the texture toward cake instead of that dense, moist brownie bite.
