Ooey gooey brownies are rich chocolate squares with a shiny, lightly crackled top and a soft, fudgy center. Butter, chopped chocolate, cocoa, and brown sugar create a deep chocolate flavor and tender texture, while a measured bake keeps the middle moist without leaving the eggs undercooked.
Ingredients
- ½ cup (113 g) unsalted butter, cut into pieces
- 6 oz (170 g) semisweet or bittersweet chocolate, finely chopped; use chocolate in the 55–70% cacao range for a balanced, rich flavor
- 1 cup (200 g) granulated sugar
- ½ cup (100 g) packed light brown sugar
- 2 large eggs (about 100 g without shells), at room temperature
- 1 teaspoon (5 ml) pure vanilla extract
- ¾ cup (95 g) all-purpose flour, spooned into the measuring cup and leveled
- ½ cup (45 g) unsweetened cocoa powder, sifted if lumpy
- ½ teaspoon (3 g) fine salt
- 1 teaspoon (2 g) instant espresso powder, optional; it deepens the chocolate flavor without making the brownies taste like coffee
Instructions
- Position a rack in the center of the oven and heat it to 350°F (175°C). Lightly grease an 8-inch (20 cm) square metal baking pan, then line it with parchment paper, leaving an overhang on two sides so the brownies can be lifted out. A metal pan gives the edges a more even bake than a glass pan; if using glass, expect the center to take a little longer and rely on the doneness checks rather than the clock alone.
- Put the butter and chopped chocolate in a heatproof bowl. Set the bowl over a saucepan containing a little gently simmering water, making sure the bowl does not touch the water. Stir until just melted and smooth, then remove the bowl and let the mixture cool for about 5 minutes. Alternatively, microwave it in 20-second bursts, stirring between each burst. Avoid overheating: scorched chocolate can turn grainy and taste bitter.
- Whisk the granulated sugar and brown sugar into the warm chocolate mixture until evenly combined. Add the eggs and vanilla, then whisk vigorously for about 45 seconds, until the mixture looks glossy and slightly thickened. This whisking helps create the delicate crackled top. The mixture should be warm, not hot; if it is steaming, let it cool another minute before adding the eggs.
- In a separate bowl, stir together the flour, cocoa powder, salt, and optional espresso powder. Add the dry mixture to the chocolate bowl and fold with a flexible spatula just until no dry streaks remain. Scrape the bottom and corners of the bowl, but stop mixing as soon as the batter is uniform. Overmixing after adding flour can make brownies tougher rather than tender.
- Scrape the thick batter into the prepared pan and spread it evenly into the corners. Smooth the top gently without pressing out the air from the batter. Bake for 32 minutes. The edges should look set and the center should remain soft, but it should not look like liquid batter. Because the batter contains eggs, check the center with a food thermometer: USDA FSIS recommends that egg dishes reach a safe minimum internal temperature of 160°F (71°C). If the center has not reached that temperature, continue baking in 2-minute increments and check again; an inserted toothpick should show damp crumbs, not wet batter.
- Set the pan on a heat-safe rack and let the brownies cool in the pan for 60 minutes before lifting them out and slicing. They will be very soft while hot and become easier to cut as they cool. For neat squares, wipe a sharp knife between cuts. Cut into 16 pieces for small, rich servings, or make 9 larger squares if you prefer a more generous portion.
Tips
- Measure flour gently. Scooping directly from the bag can pack extra flour into the cup and make the finished brownies dry or cakey. Spoon flour into the measuring cup and level it, or weigh out 95 g for the most consistent result.
- Choose chocolate you enjoy eating. Semisweet chocolate gives a familiar brownie flavor; bittersweet chocolate makes the squares more intense. If you only have milk chocolate, reduce the granulated sugar by about 2 tablespoons (25 g), since milk chocolate is sweeter and less deeply flavored.
- Use the right pan and don’t rush the cooling. A smaller or deeper pan makes a thicker brownie that needs more baking time, while a larger pan produces thinner brownies that can dry out quickly. Cooling for the full hour lets the center settle enough to slice without turning the squares into crumbs.
- Don’t judge doneness by a perfectly clean toothpick. A clean pick usually means these brownies have gone too far for a gooey texture. Look for moist crumbs, set edges, and the safe center temperature; if you keep baking until the pick is completely dry, the center will be less fudgy.
Serving Suggestions
Serve the brownies at room temperature for a dense, fudgy bite, or warm an individual portion slightly for a softer center. A scoop of vanilla ice cream makes a classic contrast, while lightly sweetened whipped cream keeps the plate simple. Fresh raspberries, sliced strawberries, or a few tart cherries provide a bright counterpoint to the chocolate. For a dessert platter, cut the brownies into small squares and serve them alongside plain cookies or fresh fruit so guests can choose a lighter or richer bite.
For a tidy presentation, let the brownies cool fully before slicing and use a long, sharp knife. If you want warm brownies for a group, cut them first and warm only the portions you plan to serve; heating the whole pan can dry out the edges before the center is warm. A small pinch of flaky salt on each serving is an easy finishing touch, especially if the chocolate is quite sweet.
Variations
Walnut brownies: Fold ¾ cup (85 g) chopped toasted walnuts into the batter with the flour mixture. Toasting brings out their flavor, but let them cool before mixing them in. Pecans work too and make the brownies a little sweeter and more buttery.
Chocolate-chip brownies: Fold in ½ cup (85 g) chocolate chips or chopped chocolate at the end. They add distinct pockets of chocolate, though the brownies will be richer and may be a little harder to slice while warm. For a less sweet variation, use dark chocolate chips.
Gluten-free option: Replace the all-purpose flour with ¾ cup (95 g) of a measure-for-measure gluten-free baking flour blend that contains a binder such as xanthan gum. Different blends absorb moisture differently, so check the center temperature and texture, and allow the brownies to cool completely before cutting. A blend without a binder may give a more fragile, crumbly square.
Swirled cream cheese: Beat 4 oz (113 g) softened cream cheese with 2 tablespoons (25 g) sugar and 1 egg yolk until smooth. Drop small spoonfuls over the batter and draw a skewer through them in a few broad passes. The extra egg makes the center temperature check especially important; bake until the brownie center reaches 160°F (71°C), then cool fully for clean slices.
Storage and Reheating
Let the brownies cool, then refrigerate them within 2 hours of baking in a covered container. They keep well for 3–4 days in the refrigerator. Chilling firms the center, so let a portion sit at room temperature for about 15–20 minutes before serving if you prefer a softer texture. Keep the pieces in a single layer or separate layers with parchment to protect the crackled tops.
For longer storage, freeze individually wrapped squares in a freezer-safe container for up to 2–3 months for best quality. Thaw them overnight in the refrigerator or at room temperature for about an hour. To serve a leftover portion warm, heat it in short microwave bursts and check that reheated leftovers reach 165°F (74°C), the USDA FSIS recommendation. At that temperature the brownie will be quite warm throughout, so let it rest briefly before eating. Avoid repeatedly warming and cooling the same portion, which can dry it out.
Frequently Asked Questions
How do I know when ooey gooey brownies are done?
Look for set edges and a center that is soft but not liquid. A toothpick inserted near the middle should come out with damp crumbs rather than raw batter. Since these brownies contain eggs, the center should also reach 160°F (71°C), the USDA FSIS safe minimum for egg dishes. If it is below that temperature, bake in 2-minute increments and check again.
Why did my brownies turn out cakey instead of gooey?
Common causes are too much flour, overmixing after adding flour, or baking longer than needed. Weigh the flour if possible, fold only until the dry streaks disappear, and begin checking around the stated bake time. A pan that is smaller or deeper can also change the baking time, so use the visual and temperature cues rather than assuming every oven and pan behaves identically.
Can I make these brownies without a mixer?
Yes. A whisk and flexible spatula are all you need. Whisk the eggs and sugars into the chocolate mixture until glossy, then fold in the dry ingredients by hand. A stand mixer is unnecessary and can make it easier to overwork the batter once the flour is added.
Can I use Dutch-process cocoa instead of natural cocoa?
Yes. This recipe does not rely on baking soda or baking powder for its rise, so either unsweetened Dutch-process or natural cocoa works. Dutch-process cocoa tends to taste smoother and less sharp, while natural cocoa can taste a little brighter. Sift either type if it has stubborn lumps.
Can I bake the batter in a 9-inch (23 cm) square pan?
Yes, but the brownies will be thinner and will usually bake faster. Start checking before 32 minutes, looking for set edges and a moist center, and confirm the center reaches 160°F (71°C). Since thinner brownies can go from fudgy to dry quickly, check every couple of minutes once the edges look set.
Can I prepare the batter ahead?
For the best texture, bake the batter soon after mixing. If you need to get ahead, bake the brownies, cool them, and refrigerate them covered; the squares hold well for several days. You can also freeze baked portions and thaw them when needed. Avoid leaving batter containing raw eggs at room temperature while waiting to bake.
