This homemade brownie recipe delivers thick, fudgy squares of chocolate perfection that make boxed mixes seem like a distant memory. After years of testing different methods, these brownies consistently earn the title of "best ever" from everyone who tries them. The secret lies in the perfect balance of cocoa powder and real chocolate chunks, creating that elusive crackly top with a dense, chewy interior.
I first developed this recipe during a snowstorm when I couldn't get to the store for a boxed mix. My family declared they were the best brownies they had ever tasted, and they've been our go-to chocolate fix ever since.
Ingredients
- All purpose flour provides structure without making brownies cakey use cake flour for an even more tender result
- Unsweetened cocoa powder delivers deep chocolate flavor Dutch processed works best for richness
- Granulated sugar creates that signature crackly top and perfect sweetness
- Unsalted butter adds richness and moisture melted with sugar for best texture
- Cold eggs provide structure and lift use straight from refrigerator
- Baking soda helps create the perfect rise and texture
- Cornstarch is the secret ingredient for extra chewiness
- Salt enhances all the flavors especially the chocolate
- Vanilla extract adds depth and complexity to the chocolate
- Chocolate chips create melty pockets throughout use high quality for best results
- Semi-sweet baking bar chunks provide texture contrast and intense chocolate flavor
Step-by-Step Instructions
- Prepare Your Setup
- Preheat your oven to exactly 325°F for that perfect fudgy texture. Line your 8x8 pan completely with parchment paper, leaving overhang on the sides to easily lift out brownies later. This step prevents any sticking and makes cleanup incredibly simple.
- Create The Chocolate Base
- Microwave butter and sugar together until the butter completely melts, about 1 minute and 15 seconds. This method creates a shiny mixture that helps develop that crackly top. Allow it to cool for exactly 5 minutes before stirring in vanilla and cocoa powder. The cooling period prevents eggs from cooking when added later.
- Mix The Wet Ingredients
- Transfer the chocolate mixture to your stand mixer and add eggs one at a time on low speed. This slow incorporation is crucial for the perfect texture. Be careful not to overmix or whip air into the batter, which would make cakey rather than fudgy brownies.
- Combine Dry Ingredients
- Whisk your flour, baking soda, cornstarch, and salt in a separate bowl until completely uniform. This ensures even distribution of leavening agents. Gradually add this mixture to your wet ingredients on low speed until just combined. Stop mixing the moment the flour disappears to avoid overdeveloping gluten.
- Add Chocolate And Bake
- Fold in chocolate chips and chunks by hand using a spatula with gentle motions. Spread the thick batter evenly in your prepared pan, paying special attention to the corners. Bake for 20-30 minutes, checking at 20 minutes by inserting a toothpick in the center. It should come out with a few moist crumbs, not completely clean or wet.

My favorite part of this recipe is using the high-quality baking chocolate. I learned from my grandmother that this makes all the difference in creating a truly memorable brownie. She always said, "If you're going to indulge in something sweet, make it worth every calorie!"
The Perfect Texture Science
The magic of these brownies lies in the precise ratio of ingredients. The higher fat content from the 11 tablespoons of butter creates that dense, fudgy texture that makes these brownies so special. The cornstarch works alongside the minimal flour to prevent gluten development, ensuring chewiness rather than cakiness. Think of cornstarch as your secret weapon for that perfect brownie bite.
Storage Solutions
These brownies actually improve with time as the flavors continue to develop. Store them at room temperature in an airtight container, and they'll remain perfectly moist for up to four days. For longer storage, wrap individual brownies tightly in plastic wrap and then foil before freezing for up to three months. The double wrapping prevents freezer burn and preserves that fresh-baked taste.
Customization Options
While this recipe creates perfect classic brownies, you can easily adapt it to create your own signature dessert. Swap walnuts or pecans for some of the chocolate chips for added texture. For a mint chocolate variation, add 1/4 teaspoon peppermint extract alongside the vanilla. Coffee lovers can dissolve 1 teaspoon of espresso powder in the vanilla for a mocha brownie that enhances the chocolate flavor without tasting like coffee.
Serving Suggestions
These brownies shine on their own but transform into an extraordinary dessert when served warm with a scoop of vanilla ice cream. For dinner parties, cut smaller squares and arrange them on a platter with fresh berries and a light dusting of powdered sugar. During the holidays, I often serve them with a drizzle of warm salted caramel sauce and a sprinkle of flaky sea salt for an elegant touch that still feels comforting.

Frequently Asked Questions About the Recipe
- → Can I double this brownie recipe?
Yes, this recipe can easily be doubled to fit a 9x13" pan. When doubling, increase the baking time by 3-5 minutes. The doubled recipe will yield approximately 24 brownies.
- → How do I know when the brownies are done baking?
The brownies are done when they are set and no longer jiggly in the center. A toothpick inserted in the center should come out with a few moist crumbs (not wet batter). Be careful not to overbake, as this will make them dry instead of fudgy.
- → What's the best way to store these brownies?
Store brownies in an airtight container at room temperature to maintain their moist and chewy texture for up to 4 days. For longer storage, wrap them tightly in plastic wrap followed by foil and freeze for up to 3 months.
- → Can I substitute the cornstarch and all-purpose flour?
Yes, you can substitute 1/2 cup of cake flour for the combination of all-purpose flour and cornstarch. The cornstarch helps create a more tender texture in the brownies.
- → Why does the recipe call for cold eggs?
Cold eggs help create that desirable crackly top on brownies. They slightly cool the warm butter-sugar mixture, creating the perfect consistency for the batter that allows the top to crack during baking.
- → What kind of chocolate works best for the chopped baking bar?
The recipe recommends using a Ghirardelli baking bar for the chopped chocolate. This high-quality chocolate melts beautifully within the brownies, creating pockets of intense chocolate flavor.
