Ingredients
This recipe uses simple ingredients that combine to create incredibly rich brownies.
- 2 cups (4 sticks) unsalted butter – Butter provides richness and moisture while helping create a dense, fudgy texture.
- 3½ cups granulated sugar – Granulated sugar sweetens the brownies and helps produce the shiny crust.
- 1½ cups packed brown sugar – Brown sugar adds moisture and a slight caramel flavor.
- 2 cups unsweetened cocoa powder – Cocoa powder gives these brownies their intense chocolate flavor.
- 8 large eggs (room temperature) – Eggs provide structure and help create the glossy top when whipped.
- 2 tablespoons vanilla extract – Vanilla enhances the chocolate flavor and adds warmth.
- 2 cups all-purpose flour – Flour gives the brownies their structure while keeping them tender.
- 1 teaspoon salt – Salt balances the sweetness and intensifies the chocolate flavor.
Baking Instructions
1. Preheat the Oven
Preheat your oven to 350°F.
Grease a half-sheet pan (16 x 11.3 inches) and line it with parchment paper, leaving some overhang on the sides. This makes it easier to lift the brownies out after baking.
2. Melt Butter and Mix Sugars
In a large saucepan, melt the butter over medium heat.
Once the butter has melted, remove the pan from the heat and stir in the granulated sugar and brown sugar.
Mix until the sugars begin to dissolve and the mixture looks thick and glossy.
Allow the mixture to cool until it is warm but not hot. This step helps prevent the eggs from cooking when added later.
3. Add Cocoa Powder
Stir the unsweetened cocoa powder into the butter and sugar mixture.
Mix thoroughly until the batter becomes smooth, glossy, and deeply chocolatey.
At this stage, the mixture will be thick but should blend easily.
4. Whip the Eggs and Vanilla
In a separate large bowl, beat the eggs and vanilla extract together for 1 to 2 minutes.
The eggs should become slightly foamy and lighter in color.
This step is key to creating the signature shiny brownie crust that everyone loves.
5. Combine the Mixtures
Slowly pour the warm chocolate mixture into the egg mixture while whisking continuously.
This gradual mixing helps prevent the eggs from scrambling.
Continue stirring until the batter is smooth and fully combined.
6. Fold in Dry Ingredients
Sift the flour and salt into the batter.
Using a spatula, gently fold the dry ingredients into the chocolate mixture until just combined.
Be careful not to overmix. Overmixing can lead to dense or tough brownies.
7. Bake
Pour the batter into the prepared sheet pan.
Use a spatula to smooth the surface evenly.
Bake for 25 to 28 minutes.
The brownies are ready when:
- The top is shiny and slightly cracked
- A toothpick inserted into the center comes out with moist crumbs but no wet batter
8. Cool and Slice
Allow the brownies to cool in the pan for 15 minutes.
Then lift the brownies out using the parchment paper overhang.
Place them on a cutting board and slice into 24 large bars or 32 medium squares.
For clean slices, use a sharp knife and wipe it clean between cuts.
Storage
These brownies store well, making them perfect for baking ahead.
Room Temperature
Store brownies in an airtight container at room temperature for 3 to 4 days. Placing parchment paper between layers prevents sticking.
Freezer
Sheet pan brownies freeze beautifully. Wrap individual portions in plastic wrap and place them in a freezer-safe container or bag. They can be frozen for up to 3 months. To serve, thaw at room temperature or warm gently in the microwave.
Tips for the Best Sheet Pan Brownies
Use Room Temperature Eggs
Room temperature eggs mix more smoothly into the batter and help create a glossy brownie crust.
Do Not Overbake
Overbaking will make brownies dry. Remove them when the center still has moist crumbs on the toothpick.
Line the Pan with Parchment
Parchment paper makes lifting and slicing the brownies much easier.
Let Them Cool Before Cutting
Cutting brownies while hot can cause them to crumble. Allowing them to cool helps them set properly.
Flavor Variations
One of the best things about sheet pan brownies is how easy they are to customize.
Chocolate Chip Brownies
Fold 1 cup chocolate chips into the batter for extra chocolate goodness.
Peanut Butter Swirl
Drop spoonfuls of peanut butter across the batter and swirl with a knife before baking.
Caramel Brownies
Drizzle caramel sauce over the batter and lightly swirl for a sweet caramel flavor.
Cookies and Cream Brownies
Fold in crushed chocolate sandwich cookies before baking.
Espresso Brownies
Add 1 tablespoon espresso powder to enhance the chocolate flavor.
FAQs
How do I know when brownies are done?
Insert a toothpick into the center of the brownies.
It should come out with a few moist crumbs but no wet batter.
If the toothpick comes out clean, the brownies may be slightly overbaked.
Can I add mix-ins?
Yes. This recipe is very flexible.
Try adding:
- Chocolate chips
- Chopped nuts (if not nut-free)
- Peanut butter swirl
- Caramel drizzle
- Crushed cookies
Fold in about 1 cup of mix-ins before baking.
Can I halve the recipe?
Yes. You can cut the ingredients in half and bake in a smaller pan if you don’t need a large batch.
However, the full sheet pan recipe is ideal for gatherings or meal prep.
Can I make these brownies gluten-free?
Yes. Substitute the all-purpose flour with a 1:1 gluten-free baking flour blend.
The texture may be slightly different, but the brownies will still be delicious.
