Recipe For A Big Batch of Brownies

This is a family favorite my mom has made many times to feed friends and gatherings. When you have hungry teenagers or a large group, a half sheet pan of these brownies always disappears fast.

The recipe makes a rich chocolate treat that looks and tastes special with a light dusting of powdered sugar. It’s reliable for bake sales, benefit auctions, team dinners, and any event where you need an economical yet satisfying dessert.

A generously greased 12×17 (half sheet) baking sheet is the perfect size. The recipe is budget-friendly without sacrificing flavor, making it a smart choice for feeding many people.

These brownies come together in about ten minutes using common pantry ingredients. If you like big-batch desserts, try Raspberry Crumb Cake next time.

Why This Recipe Works:

  • Prepared in a half sheet pan (about 18 × 12 × 1″) to fit a standard home oven; easy to scale for commercial ovens or larger mixers.
  • Flexible serving sizes — cut into small bites for parties or larger squares for generous servings.
  • Uses simple, everyday ingredients and mixes up in ten minutes or less.
  • A great way to use a lot of eggs if you have them on hand.

Ingredients Needed to Brownies For A Crowd:

  • Butter (softened)
  • Sugar
  • Eggs (about 6–7; roughly 1-1/4 cups)
  • Vanilla
  • Flour
  • Cocoa powder
  • Salt
  • Chopped nuts (optional)
  • Powdered sugar for dusting (optional)
Flour, sugar, butter, eggs, cocoa, vanilla, confectioners sugar and chopped nuts on a wooden counter top are ingredients to make brownies for a crowd

How to Make a Big Batch of Homemade Brownies

  1. Preheat the oven to 350°F (175°C). Grease a 12×17 baking sheet thoroughly.
  2. Cream the softened butter and sugar together, then stir in the vanilla.
  3. Add the eggs and beat well until the mixture is smooth and combined.
  4. In a separate bowl, whisk together the dry ingredients (flour, cocoa, salt, and optional chopped nuts). Gradually blend the dry mix into the creamed mixture until evenly incorporated.
  5. Spread the batter into the prepared baking sheet in an even layer and bake 15–20 minutes. A toothpick inserted in the center should come out clean when done.
  6. Allow the brownies to cool about 20 minutes, then dust evenly with powdered sugar if desired. Cut into pieces and serve.

A larger mixer can make handling this volume easier, but a 4.5-quart mixer will work if you mix carefully at slower speeds to avoid splashing. Once ingredients are combined, you can increase the speed briefly to finish mixing.

Using a fine sifter to dust powdered sugar creates a uniform, attractive finish, but you can also sprinkle it by hand if needed. The powdered sugar is optional but adds a nice visual touch.

Step By Step Instructions

Cream softened butter with sugar until light and fluffy. Add vanilla, then the eggs, beating until the mixture is smooth. Scrape the bowl sides and bottom with a spatula as needed.
