Sheet Pan Brownies

I still remember the first time I made brownies in bulk—friends gathered around the table while warm pans of brownies cooled on the counter, tantalizing us with their rich aroma. There’s just something magical about a homemade brownie, especially when they’re freshly baked and a little gooey in the middle. This version is not only easy to whip up, but it’s also a delicious way to use a half-sheet pan to feed a crowd or stock your freezer with sweet treats for those late-night cravings. Trust me; once you’ve had a bite of these fudgy beauties, you’ll want to make them again and again.

Why You’ll Love This Recipe

Simple & Quick: The whole baking process takes just under an hour, so you can enjoy delicious brownies without a lengthy wait.
Irresistible Flavor: Each bite is packed with deep chocolate goodness and a rich, fudgy texture that makes your taste buds dance.
Eye-Catching Appeal: They come out of the oven looking divine, with glossy chocolate bits sprinkled on top, making them as lovely to look at as they are to eat.
Flexible Serving: Perfect for any occasion, whether it’s a snack, dessert for a dinner party, or even breakfast with your morning coffee.
Diet-Friendly Options: Easily adaptable to make gluten-free if you swap in gluten-free flour, so everyone can enjoy a bite (or two).

Ingredients You’ll Need

2 ½ cups plus 2 tablespoons all-purpose flour: This provides the structure of your brownies. If you need gluten-free, try a one-to-one gluten-free flour blend.
1 ½ cups dutch-processed cocoa powder: This type of cocoa gives the brownies a rich, dark chocolate flavor. Always sift it to avoid lumps.
5 cups chopped bittersweet chocolate: Using quality bittersweet chocolate elevates the taste. Feel free to use semisweet if it’s what you have on hand.
2 ¼ cups butter, diced: Butter adds richness and moisture. Ensure it’s at room temperature for better incorporation.
9 large eggs: Cold eggs give extra lift and structure to the batter—just whip them well before adding to the mix.
3 ¾ cups granulated sugar: This sweetener balances the bitterness of the cocoa. It dissolves quickly when mixed and contributes to a shiny crust.
⅓ cup vegetable oil (or olive oil): Adding oil keeps the brownies moist while contributing to the fudgy texture.
2 tablespoons vanilla extract: Pure vanilla extract enhances the overall flavor; synthetic vanilla won’t yield the same depth.
1 ½ tablespoons espresso powder: This is optional but boosts the chocolate flavor beautifully. If you don’t have espresso powder, instant coffee works in a pinch.
2 ¼ teaspoons salt: A little salt enhances sweetness and balances flavors, making the chocolate sing.
1 ½ cups chopped bittersweet chocolate (for topping): This adds nice texture and extra chocolaty goodness on top.

How to Make Sheet Pan Brownies

Preheat the Oven: Start by preheating your oven to 350°F (180°C). Prepare your 13 x 18 inch (33 x 46 cm) half sheet pan by buttering it and lining it with parchment paper.
Sift Dry Ingredients: In a medium bowl, sift together the 2 ½ cups plus 2 tablespoons of all-purpose flour and 1 ½ cups of cocoa powder. This step helps to aerate the mix, ensuring a light brownie texture. Set it aside.
Melt Chocolate and Butter: In a large, microwave-safe bowl, combine the 5 cups of chopped bittersweet chocolate and 2 ¼ cups of diced butter. Heat in the microwave for 1 minute and stir. Continue heating in 30-second increments until it’s just melted, then let it cool for about 10 minutes.
Whip the Eggs Mixture: In the bowl of a stand mixer fitted with a whisk attachment, whip together the 9 large eggs, 3 ¾ cups of granulated sugar, ⅓ cup of vegetable oil, 2 tablespoons of vanilla extract, 1 ½ tablespoons of espresso powder, and 2 ¼ teaspoons of salt on medium-high speed for 8 minutes until the mixture is thick, pale, and glossy.
Combine the Mixtures: Reduce the mixer speed to medium, then slowly pour in the melted chocolate mixture, mixing until fully incorporated.
Fold in Dry Ingredients: Gently fold the sifted flour and cocoa powder mixture into the wet ingredients just until combined. Try to avoid over-mixing, as it can lead to denser brownies.
Pour the Batter: Spread the thick brownie batter evenly into the prepared pan using a spatula.
Add Toppings: Sprinkle the remaining 1 ½ cups of chopped bittersweet chocolate over the top of the brownie batter for that extra chocolaty layer.
Bake: Place the pan in the preheated oven and bake for about 40 minutes. The edges should feel set, but the middle should have a slight giggle when you shake the pan.
Cool and Serve: Allow the brownies to cool completely in the pan before slicing into squares. They’re wonderful served with a cold glass of milk. Leftovers can be stored in an airtight container at room temperature for up to 3 days.

Storing & Reheating

To keep your brownies fresh, store them in an airtight container at room temperature for up to 3 days. If you need to store them longer, transfer the brownies to the fridge, which can extend their freshness for about a week. For longer storage, freeze them! Wrap individual pieces in plastic wrap and place them in a freezer-safe bag for up to 3 months. Reheat brownies by placing them in the microwave for about 10–15 seconds; however, remember that texture may change slightly after freezing, but they’ll still be tasty!

Chef’s Helpful Tips

Room Temperature Ingredients: Make sure your eggs and butter are at room temperature for even mixing and better texture.
Don’t Overmix: Mixing too much after adding the flour can develop the gluten and lead to tougher brownies—just mix until combined.
Check for Doneness: Remember to look for that “slight giggle” in the center; this means they’ll set up perfectly as they cool.
Customize Your Flavors: Adding nuts or chocolate chips can take these brownies to another level; feel free to get creative!

A delightful treat awaits you with these moist, fudgy brownies, each bite echoing the familiar warmth of homemade comfort food. Baking is about exploration; don’t hesitate to adjust ingredients, mix in some nuts, or even swap cocoa powder for a flavored one. Enjoy the process, and don’t forget to share your delicious results!

Recipe FAQs

Can I use a different type of chocolate?

Absolutely! While bittersweet chocolate works beautifully, you can use semisweet or even dark chocolate. Just consider the sweetness level, especially if you adjust other sweeteners.

What if I don’t have espresso powder?

If you don’t have espresso powder, instant coffee can be an effective substitute. It enhances the chocolate flavor without giving a strong coffee taste.

Are these brownies better chilled or at room temperature?

These brownies are delightful both ways! Chilling them can give a firmer texture, making them easier to cut into clean squares, while at room temperature they’ll be wonderfully fudgy.

Can I double the recipe?

Yes, if you have the space, doubling this recipe works perfectly! Just use a larger pan, and keep an eye on the baking time as it may vary slightly.

Enjoy your baking adventure and the many smiling faces you’ll encounter when you share these delectable sheet pan brownies!
