This chocolate brownie recipe produces a dense, fudgy square with a paper-thin crackly top, and it does it in 50 minutes with one bowl and one pan. The key is a 1:1.25 ratio of flour to melted butter by volume and pulling the pan at an internal temperature of 205F (96C), which keeps the center molten without raw batter.

Most brownie failures trace to two numbers: overmixing after the flour goes in, which builds gluten and turns fudge into cake, and overbaking past 210F (99C), which dries the crumb. I give you both numbers below, plus the exact cue to look for at the oven door.
You need 8 ingredients, all of which you probably have. The recipe yields 9 generous squares from an 8-inch pan, at roughly 285 calories each – a real estimate from the actual butter, sugar, eggs, chocolate, and flour in the list.
Why You'll Love This Recipe
About the Ingredients
10 tbsp (140g) unsalted butter
Melted butter carries the fat and gives the fudgy crumb. Salted butter works, but cut the added salt to 1/8 tsp; European-style butter with 82% fat gives a slightly richer result.
7 oz (200g) dark chocolate, 60-70% cacao, chopped
Chopping bar chocolate beats chips because chips contain stabilizers that resist melting smoothly. If you only have semisweet chips, use them and reduce the sugar by 2 tbsp.
1 1/4 cups (250g) granulated sugar
Sugar does more than sweeten – it keeps the crumb moist and drives the crackly top. Do not swap in honey or maple syrup; liquid sweeteners throw off the moisture balance.
3 large eggs, room temperature
Room-temperature eggs emulsify into the batter and prevent a greasy top. Pull them out 30 minutes early, or rest them in warm tap water for 10 minutes.
2 tsp vanilla extract
Vanilla rounds out the bitterness of high-cacao chocolate. Bourbon vanilla is the standard choice; imitation vanilla is fine in a pinch but tastes flatter.
3/4 cup (95g) all-purpose flour
Flour is the only structural ingredient, so measure by weight. If you must substitute, use bread flour minus 1 tbsp; do not use self-rising flour, which adds leavening and cakes the texture.
1/4 cup (25g) unsweetened cocoa powder
Dutch-process cocoa gives a darker color and smoother flavor. Natural cocoa works too but is more acidic; either way, sift it to avoid dry pockets.
1/2 tsp fine sea salt
Salt sharpens the chocolate flavor and keeps the brownies from tasting flat. Kosher salt works if you use 3/4 tsp by volume.
Tips & Tricks
Stop Mixing at the Right Moment
Fold the flour in with a spatula just until the streaks disappear – about 12 to 15 strokes. Extra mixing develops gluten and turns fudge into cake.
Use the Temperature, Not the Timer
Ovens run hot or cold by 25F (14C) or more. A 205F (96C) internal reading in the center is the real doneness signal; the toothpick test is unreliable with molten chocolate.
Cool Completely Before Cutting
Wait at least 2 hours, or the center will smear. For clean edges, chill 30 minutes and wipe the knife between cuts.
Weigh Your Flour
A packed cup of flour can weigh 140g instead of 95g, which dries the batch out. A $12 kitchen scale pays for itself in one bake.
Pro Tips
Step-by-Step Instructions
1. Preheat and line the pan
Heat the oven to 350F (175C). Line an 8-inch square metal pan with parchment, leaving a 2-inch overhang on two sides, and grease lightly. Metal conducts heat more evenly than glass here.
2. Melt butter and chocolate
Combine the butter and chopped chocolate in a saucepan over low heat, stirring constantly, for 4 to 5 minutes until smooth and glossy. Pull it off the heat the moment no lumps remain – scorched chocolate turns grainy.
3. Whisk eggs and sugar
Whisk the eggs, sugar, vanilla, and salt in a large bowl for 3 full minutes until the mixture is pale, thick, and falls in a ribbon. This aeration is what forms the crackly top.
4. Blend in the chocolate
Pour the warm chocolate mixture into the egg mixture in a slow stream while whisking. The batter should turn glossy and uniform; if it looks greasy, the chocolate was too hot – whisk harder to re-emulsify.
5. Fold in the dry ingredients
Sift the flour and cocoa over the batter and fold with a spatula for 12 to 15 strokes, just until no dry streaks remain. Stop there – lumps are better than a tough brownie.
6. Bake to temperature
Scrape into the pan and bake at 350F (175C) for 28 to 32 minutes, until the edges are set and slightly pulling from the pan and the center reads 205F (96C) on an instant-read thermometer. The top should look dry and crackled, not wet.
7. Cool before cutting
Cool in the pan on a wire rack for at least 2 hours. Lift the slab out by the parchment, then cut into 9 squares with a long knife, wiping the blade between cuts.
Delicious Variations
Triple Chocolate
Fold 3/4 cup (130g) chocolate chunks and 1/2 cup (60g) white chocolate chips into the batter in the final strokes for layered texture.
Salted Caramel Swirl
Dollop 1/3 cup (100g) thick caramel over the batter and drag a knife through it twice before baking; bake 2 minutes longer.
Espresso Fudge
Add 1 tbsp instant espresso powder to the melted chocolate and top the cooled slab with a dusting of cocoa and flaky salt.
How to Store Chocolate Brownie Recipe
Refrigerator
Store cut squares in an airtight container at room temperature for 4 days, or refrigerate for up to 7 days – chilling makes them denser and fudgier.
Freezer
Wrap individual squares in plastic, then foil, and freeze for up to 3 months. Thaw at room temperature for 45 minutes.
Reheating
Microwave a single square for 10 to 15 seconds at 50% power, or warm the whole pan covered with foil at 300F (150C) for 8 minutes.
Frequently Asked Questions
Q: Why are my brownies cakey instead of fudgy?
You either overmixed the flour or used too much of it. Fold just until the streaks vanish and weigh the flour at 95g per 3/4 cup; a packed cup can add 45g and cake the crumb.
Q: How do I get the shiny crackly top on brownies?
Whisk the eggs and sugar for 3 full minutes before adding anything else. That dissolved sugar rises to the surface during baking and sets into the thin glossy crust.
Q: Can I use cocoa powder instead of chocolate?
Yes, but you need more fat – replace the 200g chocolate with 3/4 cup (75g) cocoa, add 4 tbsp butter, and increase sugar to 1 1/2 cups (300g). The result is chewier and less rich, so bar chocolate remains the better choice.
Q: How do I know when brownies are done without a toothpick?
Use an instant-read thermometer – 205F (96C) in the center means done. A toothpick will come out with wet batter even when the brownie is perfectly baked, because the center stays molten by design.
Q: Can I double this chocolate brownie recipe?
Yes, double everything and bake in a 9×13-inch pan at 350F (175C) for 32 to 38 minutes, checking the internal temperature at 30 minutes. Do not double the time – the larger pan only needs about 5 extra minutes.
Bake one batch this week, take the internal temperature at the 28-minute mark, and note what your oven actually does. That single data point will improve every brownie you make from here on. Stay sharp, stay solvent.
