Can I use a different pan size?

Absolutely! The classic recipe uses a jelly roll pan (10x15 inches), but my mom always made hers in a 13x9 inch dish. Just adjust the baking time - thicker brownies in a smaller pan might need 5-10 extra minutes. Keep an eye on them and use the toothpick test to check for doneness.

My frosting is too thick/thin - help!

No worries, this happens to me all the time! If your frosting is too thick, add milk a teaspoon at a time until it's spreadable. Too thin? Add more powdered sugar gradually. Remember, the frosting thickens as it sets on the warm brownies, so err on the side of slightly too thick rather than too runny.

Can I make substitutions for dietary needs?

You bet! For gluten-free, I've had good results with a 1:1 gluten-free flour blend. Dairy-free? Use vegan butter and your favorite milk alternative. The recipe is pretty forgiving - just keep the wet-to-dry ratios about the same. The texture might change slightly, but the flavor will still be amazing.

Why do the brownies need to be warm when frosting?

This is my favorite trick! The heat helps the frosting melt just enough to create that signature glossy finish while still holding its shape. If the brownies are too hot, the frosting will melt completely. Too cold, and it won't adhere properly. Aim for "warm to the touch", about 15 minutes out of the oven.

Can I add nuts or other mix-ins?

Of course! While the original recipe is pure chocolate bliss, I sometimes add ½ cup of chopped walnuts or pecans to the batter. Chocolate chips are great too - just sprinkle them on top before baking so they don't sink. Keep in mind this changes the nostalgic flavor a bit, but sometimes change is good!

Ingredients

Scale

For the Brownies:

1 cup (2 sticks) unsalted butter, melted and slightly cooled
½ cup unsweetened cocoa powder
2 cups all-purpose flour
2 cups granulated sugar
4 large eggs, room temperature
1 tablespoon vanilla extract

For the Chocolate Frosting:

¼ cup (½ stick) unsalted butter, softened
¼ cup unsweetened cocoa powder
3 cups powdered sugar, sifted (optional)
½ cup milk or heavy whipping cream
1 teaspoon vanilla extract

Instructions

Prepare the Brownie Batter: Preheat oven to 350°F (175°C). Lightly spray a 10x15x1-inch jelly roll pan or a 13×9-inch baking dish with cooking spray. In a large bowl, mix melted butter and cocoa powder until smooth. Add flour and sugar; stir until just combined. Beat in eggs and vanilla extract until smooth. Do not overmix.
Bake the Brownies: Pour batter into the prepared pan and spread evenly. Bake for 20–25 minutes, or until a toothpick inserted into the center comes out clean.
Prepare the Chocolate Frosting: While brownies bake, beat together softened butter, cocoa powder, powdered sugar, milk, and vanilla extract until smooth and creamy.
Frost the Brownies: Let brownies cool for 15-20 minutes, then spread frosting over the warm surface for a glossy finish. Let the frosting set before cutting.
Serve & Store: Slice into squares and enjoy! Store leftovers in an airtight container at room temperature or in the fridge for up to 3 days.

Notes

For an extra fudgy texture, underbake the brownies slightly and frost while still warm.
You can also sprinkle mini chocolate chips or chopped walnuts on top before the frosting sets!
