These old-fashioned brownies are the kind of simple, deeply chocolatey dessert that feels timeless from the very first bite.
Made in just one bowl, they combine everyday baking ingredients with unsweetened Hershey’s cocoa and dark chocolate chips for a rich chocolate flavor without a complicated preparation.
Melted butter gives the brownies a tender, satisfying richness, while sugar and eggs help create the soft, chewy center and firm edges that make classic brownies so appealing.
The batter comes together easily by first blending the cocoa and baking soda with melted butter and boiling water, then adding the sugar, eggs, remaining butter, flour, vanilla, and salt.
Dark chocolate chips are folded in at the end, adding little pockets of chocolate throughout the finished brownies.
Once spread into a greased 9-by-13-inch pan and baked, the surface develops the characteristic crackly appearance while the inside remains soft and chewy.
One of the most important parts of this recipe happens after baking: allowing the brownies to cool in the pan for about 30 minutes before removing them.
This helps the large brownie hold together and also makes it easier to cut into neat squares.
The finished recipe yields 24 brownies, making it a practical choice for sharing, dessert trays, family gatherings, or simply keeping a batch ready for chocolate cravings.
With a straightforward method, familiar ingredients, and a wonderfully rich texture, these brownies deliver classic homemade comfort without unnecessary fuss.
Classic American Brownies with Chocolate Chips
Ingredients
Equipment
Method
- Preheat the Oven: Preheat the oven to 350°F.
- Prepare the Pan: Grease a 9 × 13-inch baking pan and set it aside.
- Combine Cocoa and Baking Soda: Add the unsweetened cocoa and baking soda to a large bowl and stir until evenly combined.
- Add the First Portion of Butter: Melt the 2/3 cup butter over low heat on the stovetop or melt it in the microwave. Using a wooden spoon, stir half of the melted butter into the cocoa and baking soda mixture until combined.
- Add Boiling Water: Pour 1/2 cup boiling water into the cocoa mixture and stir thoroughly until incorporated.
- Build the Batter: Add the sugar, eggs, and the remaining melted butter to the bowl. Stir until the ingredients are well combined.
- Add Flour and Flavorings: Sift the 1 1/3 cups all-purpose flour into the mixture. Add the vanilla and salt, then stir until the batter is smooth and evenly combined.
- Fold in Chocolate Chips: Add the dark chocolate chips and stir them through the batter until they are distributed throughout.
- Fill the Pan: Pour the brownie batter into the prepared baking pan. Use the wooden spoon to smooth the surface evenly.
- Bake the Brownies: Bake at 350°F for 35–40 minutes. The source recipe took 35 minutes. Check for doneness with a toothpick.
- Cool in the Pan: Allow the baked brownie to cool in the pan for about 30 minutes before attempting to remove it. This helps prevent the brownie from breaking apart.
- Remove from the Pan: Once cooled, gently loosen the edges of the brownie from the pan using a thin metal spatula, then carefully remove the whole brownie from the pan.
- Cut and Serve: Cut the cooled brownie into 24 individual squares.
Notes
- Use unsweetened cocoa as specified to maintain the intended rich, dark chocolate flavor.
- The butter should be divided into two portions: half is mixed with the cocoa and baking soda, while the remaining half is added later with the sugar and eggs.
- The boiling water is added directly to the cocoa and butter mixture before the sugar and eggs are incorporated.
- Sift the flour into the bowl to help it blend smoothly into the brownie batter.
- Do not skip the 30-minute cooling period. The large brownie is delicate while warm and can break apart when removed too early.
- For cleaner individual squares, let the whole brownie cool before cutting it into 24 pieces.
- A toothpick can be used to check the brownies for doneness around the 35-minute mark, noting that the source recipe baked successfully in 35 minutes.
Chef’s Secret
The most important trick for these brownies is to treat the cooling stage as part of the recipe rather than an optional wait.
Because the brownies are baked as one large slab in a 9 × 13-inch pan, they can be fragile immediately after coming out of the oven.
Letting them rest in the pan for about 30 minutes allows the structure to settle enough for the brownie to be loosened and lifted without falling apart.
Run a thin metal spatula gently around the edges before removing the slab.
For especially neat squares, resist the temptation to cut while the brownie is still warm.
Allowing the entire uncut brownie to cool first gives you a much cleaner result when dividing it into 24 pieces.
Serving Suggestions
Serve these rich brownies as they are for a classic chocolate dessert, or pair individual squares with a scoop of ice cream for a simple dessert combination.
They can also be arranged on a dessert platter when serving a group.
The dark chocolate chips throughout the brownies provide plenty of chocolate flavor on their own, so minimal garnishing is needed.
For an easy presentation, serve the brownies in neat squares after they have completely cooled.
Conclusion
These Old-Fashioned Brownies deliver everything you want from a classic homemade brownie: deep chocolate flavor, chewy centers, firm edges, a crackly top, and pockets of dark chocolate chips.
With a straightforward one-bowl method and familiar ingredients, they are easy to prepare while still producing an irresistibly rich dessert.
Allowing the finished brownie to cool properly is the key to getting a sturdy slab and clean, attractive squares.
