These brownies are my go-to when I want something chocolatey, dense, and impossibly fudgy. They come together with straightforward steps, and the result is a glossy, crackly-top bar that holds a moist, almost molten center. I make them when I need to bring dessert to a party, when I want an indulgent treat after dinner, or when I just need the comfort of a really good brownie.
I’ll walk you through the exact recipe I use, the gear that makes the process easier, and the small tips that keep these brownies reliably perfect. No complicated techniques, no temperamental timing—just practical steps that deliver consistent results.
Read straight through for a clear plan to make these tonight, or skip to the sections you need: ingredients, step-by-step method, troubleshooting, and storage. Let’s get to it.
The Essentials
Yield: 12 bars. Pan: 9″ x 13″ baking dish. Bake temp: 350°F (175°C). Total hands-on time: about 20 minutes; bake time: 30 minutes plus cooling. Difficulty: easy–moderate—there are a few small things to watch, but nothing technical.
These are classic fudgy brownies with two layers of chocolate work: most of the chocolate melts into the batter, and a small amount gets chopped and folded in for pockets of texture. The batter is rich and fairly dense; the trick for the fudgiest interior is not to overmix after adding the flour and not to overbake.
Ingredients
- Cooking spray — For greasing the pan so the parchment stays in place and the brownies lift out cleanly.
- 12 oz semi-sweet chocolate, divided (10 oz. and 2 oz.) — 10 oz. melts into the batter for deep chocolate flavor; 2 oz. is chopped and stirred in for texture.
- 16 tablespoons unsalted butter (2 sticks) — Adds richness and helps the brownies set with a fudgy crumb.
- 1½ cups all-purpose flour — Provides structure; measure gently—too much flour makes brownies cakier.
- ¼ cup unsweetened cocoa powder (we use Hershey’s) — Intensifies chocolate flavor and contributes to the dark color.
- 1 teaspoon Kosher salt — Balances sweetness and enhances chocolate flavor.
- 1½ cups sugar — Main sweetener; helps create the shiny top when mixed properly.
- ½ cup brown sugar (dark) — Adds depth and a hint of molasses flavor.
- 5 large eggs, room temperature — Eggs add structure and richness; room temperature eggs incorporate more smoothly.
- 2 teaspoon vanilla extract — Rounds out the chocolate and adds aroma.
- 1 tablespoon sea salt coarse, optional — Sprinkle on top while slightly warm for a salty contrast to the rich chocolate.
Method: Ultimate Fudge Brownies
- Preheat the oven to 350°F (175°C). Spray a 9″ x 13″ baking dish with cooking spray and line it with parchment paper, leaving overhang on two opposite sides for lifting.
- In a medium bowl, whisk together 1½ cups all-purpose flour, ¼ cup unsweetened cocoa powder, and 1 teaspoon kosher salt. Set aside.
- Chop 2 ounces of the semi-sweet chocolate and set aside for later.
- Place 16 tablespoons (2 sticks) unsalted butter and 10 ounces of the semi-sweet chocolate in a large microwave-safe bowl. Microwave on HIGH in 1-minute intervals, stirring between intervals, until the butter and chocolate are fully melted and smooth. (Be careful not to overheat.)
- Stir 1½ cups sugar and ½ cup dark brown sugar into the melted chocolate-butter mixture until the sugars are mostly dissolved and the mixture is smooth.
- Add the 5 large room-temperature eggs to the chocolate mixture one at a time, whisking well after each egg until fully incorporated.
- Stir in 2 teaspoons vanilla extract.
- Gently fold the flour/cocoa mixture (from step 2) into the wet mixture, stirring just until no dry streaks remain and the batter is uniform.
- Stir the chopped 2 ounces of semi-sweet chocolate into the batter.
- Pour the batter into the prepared baking dish and smooth the top with a spatula. Bake at 350°F for 30 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs but not wet batter.
- Remove the pan from the oven and transfer to a wire rack to cool. If using, sprinkle up to 1 tablespoon coarse sea salt over the top while slightly warm.
- When cool enough to handle, use the parchment overhang to lift the brownies from the pan onto a cutting board. Cut into 12 bars.
Why You’ll Love This Recipe
The texture is the main reason: glossy, crackled top with a dense, fudgy interior. It satisfies a chocolate craving without being cakey or dry. The use of both melted chocolate and chopped chocolate gives you body and bursts of melty chunks in every bite.
It’s also very forgiving. The steps are simple, mostly one-bowl or microwave work, and the flavors are classic—no unusual ingredients required. Because the batter is dense, these brownies travel well and keep their structure when cut into bars.
Healthier Substitutions
- Reduce sugar: Start by lowering the granulated sugar by ¼ cup and taste. Keep in mind texture can change—the top may be less glossy and the bite slightly less fudgy.
- Butter swap: You can substitute equal parts melted coconut oil for the butter in a pinch; notes will change slightly and the texture may be a touch less rich.
- Chocolate options: Use high-quality 60–70% dark chocolate if you want less sugar and more chocolate intensity. Avoid milk chocolate if you want the same structure; milk chocolate contains more milk solids and sugar.
- Flour alternatives: For a slightly denser, nuttier bar, you can replace up to half the flour with almond flour, but the brownies will be more fragile and less classic fudgy.
What’s in the Gear List
- 9″ x 13″ baking dish — for the right thickness and bake time.
- Parchment paper and cooking spray — parchment lifts the brownies cleanly; spray helps it stick.
- Large microwave-safe bowl — to melt butter and chocolate safely.
- Medium mixing bowl — for dry ingredients.
- Whisk and spatula — whisk for combining wet ingredients; spatula for folding and smoothing.
- Measuring cups and spoons — accurate measurements matter, especially for flour and cocoa.
- Wire rack — helps brownies cool evenly and finish setting.
- Chef’s knife and cutting board — for chopping the chocolate and slicing bars.
Mistakes Even Pros Make
- Overbaking: Pulling the brownies out when a toothpick comes out with a few moist crumbs is key. If the toothpick comes out clean, you’ve likely passed the fudgy window and will end up with a firmer, more cake-like texture.
- Overmixing after flour: Once you add the dry ingredients, fold just until no dry streaks remain. Vigorous mixing develops gluten and can make brownies tougher.
- Overheating chocolate: When melting in the microwave, stop and stir frequently. Overheated chocolate can seize or become grainy, which affects texture.
- Not using room-temperature eggs: Cold eggs don’t incorporate as smoothly, which can leave streaks or cause less glossy tops.
- Incorrect pan size: Using a smaller pan makes thicker brownies and increases bake time; a larger pan makes thinner brownies that bake faster. Stick with 9″ x 13″ for the recipe’s timing.
Make It Fit Your Plan
Need to meal-plan or fit these into a week? They freeze beautifully. Wrap cooled bars tightly in plastic wrap and store in a sealed bag for up to 3 months. Thaw at room temperature or warm briefly in a low oven for a fresh-baked feel.
If you want a smaller batch, halve the recipe and bake in an 8″ square pan—start checking at 20 minutes and expect a slightly different bake time. If you double it, use two pans rather than a much larger single pan to keep bake times consistent.
Little Things that Matter
- Room-temperature eggs: They blend smoothly and help produce that shiny top.
- Chop chocolate finely: Small pieces disperse evenly and give pockets of melty texture without sinking to the bottom.
- Let them cool before cutting: The brownies set as they cool. Cutting too soon yields messy slices.
- Use coarse sea salt sparingly: A light sprinkle while warm gives a bright contrast—don’t overdo it.
- Tap the pan gently: Once you’ve smoothed the batter, give the pan a light tap on the counter to release air bubbles for a nicer top texture.
Storage Pro Tips
- Room temperature: Store in an airtight container at room temp for up to 3 days. Layer with parchment to prevent sticking.
- Refrigeration: If your kitchen is warm or you prefer a firmer bar, refrigerate up to a week. Bring to room temperature before serving for best texture.
- Freezing: Wrap individual bars or the whole block tightly in plastic wrap, then foil. Freeze up to 3 months. Thaw overnight in the fridge or at room temperature for a few hours.
- Reheating: For a just-baked feel, warm a bar in a 300°F oven for 5–8 minutes or microwave for 10–15 seconds—watch closely so it doesn’t overcook.
Reader Q&A
- Q: Can I make these without a microwave? A: Yes. Melt the butter and 10 oz. chocolate in a heatproof bowl set over a saucepan of simmering water (double boiler), stirring until smooth. Proceed with the recipe.
- Q: What if my batter looks grainy after melting? A: If the melted mixture looks grainy, it may have overheated or the chocolate seized. Try stirring in a teaspoon of warm heavy cream or a small piece of warm butter to smooth it out. If that fails, start with fresh chocolate.
- Q: Can I use salted butter? A: You can, but reduce or omit additional kosher salt in the dry mix and be cautious with the optional coarse sea salt on top.
- Q: How do I get a crinkly top? A: Proper incorporation of sugar and thorough whisking of the eggs into the warm chocolate mixture helps create the shiny, crackly top. Don’t skip whisking the eggs in one at a time.

Notes
Notes
Semisweet morsels can be used in place of block chocolate. You'll need 2 cups.
We use our food processor to chop the 2 oz. of chocolate that gets stirred into the batter just before baking. If using morsels, this is half a cup (from the total 2 cups).
If the batter is crumbly, or just barely wet, after inserting the toothpick, that's okay. These brownies are very moist and will always leave a little of the gooey chocolate on the toothpick.
The brownies are delicious right out of the oven, but they will still be very gooey and pliable and when you slice them, they will crumble quite a bit. We recommend letting them cool on a baking rack for at least an hour before slicing.
The brownies will keep in an air-tight container in the refrigerator for up to 1 week, or on the counter for several days. The brownies can be frozen for up to 2 months.
They are amazing when slightly reheated in the microwave and then served with a scoop of vanilla ice cream on top!
