They are deeply chocolate and covered in buttery, bittersweet chocolate frosting. Even better, these brownies are super easy to make and only take about an hour, start to finish.
Super Easy Frosted Fudge Brownies for a Crowd
This is the recipe to turn to when you need to bake for a crowd.

Everyone loves brownies and these are the crowd pleasing variety. Plus, they're easy on the baker. In about an hour you'll have 32 large or 64 small brownies. Done and done.
If you want to bake a lot of brownies, you're going to need a large sheet pan
This recipe requires a large sheet pan - 21 inches long, 15 inches wide. If you try to bake these brownies in a smaller sized pan, even slightly smaller, the batter will overflow. Even in a large sheet pan, there will be a moment when you'll wonder if you're going to end up with brownie batter all over the inside of your oven.
It'll be alright. But, if you're concerned, put some foil under the pan. The brownies will puff up to the point of almost overflowing the pan, but then solidify from brownie batter into brownies. As they cool, the brownies will sink down into the pan, giving them a dense, fudgy texture.
If you'd rather bake these brownies in a smaller pan, no problem. Just just divide the batter in half and bake them in batches.
How to store these brownies:
After they are frosted, these brownies will keep well for up to 24 hours. Cover them as tightly as you can and store them at room temperature, or in the refrigerator if your home is quite warm. If you're making them in advance, wait until you're getting ready to serve them to cut them into individual brownies. This will help keep them super moist and fudgy.
Before they are frosted, the brownies will keep well for a bit longer. Cover them tightly and store them at room temperature for up to 48 hours or in the refrigerator for up to 4 days. Frost and slice right before serving.
If you'd like to freeze these brownies, I suggest doing so before they are frosted. If your freezer is large enough, leave them in the pan, cover them tightly and freeze for up to 3 months. Let the brownies thaw in the refrigerator over night, then frost and cut right before serving.
If your freezer isn't large enough to fit the entire pan of brownies, cut them into smaller portions. Since these are super moist and fudgy brownies, it will be difficult to remove them from the pan if you cut them too large. But there's no need to cut them into 64 pieces. I'd suggest cutting them into 32 pieces, wrapping all 32 brownies individually before placing in the freezer.
Allow the brownies to thaw in the refrigerator overnight then frost and cut each of the 32 brownies in half so that you have 64 smaller brownies.

FOR THE BROWNIES:
- 4 cups packed dark brown sugar
- 1 ⅓ cup (21 ⅓ tbsp) salted butter, at room temperature
- 12 large eggs, at room temperature
- 2 tablespoon pure vanilla extract
- 1 teaspoon salt
- 1 ⅓ cup + ¾ cup unbleached all-purpose flour
- 1 cup cocoa powder (not dutch process)
- 2 ½ cups semi-sweet or bitter-sweet chocolate chips
FOR THE FROSTING:
- 1 cup semi-sweet or bitter-sweet chocolate chips
- ¾ cup powdered (confectioners) sugar
- ⅓ cup milk
- 1 stick (8 tbsp) salted butter
- ¾ teaspoon salt (*See note)
- 2 teaspoon pure vanilla extract
MAKE THE BROWNIES:
- Butter a large sheet pan and heat the oven to 350 degrees.
- In the bowl of a standing mixer fitted with the paddle attachment, beat the brown sugar with the butter on medium-high speed until combined, about 1 minute.
- With the mixer running on medium-low speed, add the eggs one at a time, beating for 10-20 seconds after each addition, making sure to fully incorporate one before adding the next. Stop the mixer to scrape down the sides of the bowl a few times during this process. Add the vanilla when you add the last egg, beating just long enough to combine.
- In a separate bowl, add the salt, flour, and cocoa powder and stir with a wire whisk to combine. Add to the standing mixer bowl and beat on the lowest speed just to incorporate. Using a spatula, give the batter a stir to make sure all the flour has been mixed into the batter.
- Pour the batter into the buttered sheet pan and smooth it into an even layer. Sprinkle the chocolate chips evenly over the batter. Bake for 21 - 24 minutes, until the brownies are just barely set in the center of the pan.
- Set the pan on a wire rack and let cool completely before frosting.
MAKE THE FROSTING:
- Put the chocolate chips in a medium size bowl and set aside.
- Add the powdered sugar, milk, butter, and salt to a medium size sauce pan set over medium-high heat. Cook, stirring frequently, until the butter melts and the mixture comes to a boil. Let boil, stirring constantly, for 30 seconds.
- Pour the butter and sugar mixture over the chocolate chips and let sit for 5 minutes. Stir until all the chocolate chips are melted and the frosting is smooth, then stir in the vanilla.
- Pour the frosting over the cooled brownies, spreading it into a thin even layer. Let the frosting set for at least 30 minutes before cutting and serving.
- Using ¾ teaspoon salt and salted butter in the frosting will create a salted-chocolate flavor that I think is delicious next to the sweetness of the brownies. However, if you are not a fan of salted chocolate, go easy on the salt, starting with ¼ tsp, tasting the frosting when you're done making it and adding more if you like, until it taste right to you.
