Fudgy Brownies
Shiny, crackly tops and dense fudgy middles — from melted chocolate plus cocoa, and a full minute of whipping the eggs and sugar.
The crackly top everyone chases comes from one specific step: whipping the eggs and sugar for a full minute before anything else joins the bowl. That dissolves the sugar into the eggs, and it rises to the surface in the oven as that thin, shiny shell over a dense, fudgy middle.
Use a chocolate you'd happily eat straight — it's most of the flavor. Our guide to the best chocolate for baking names reliable supermarket bars that melt beautifully.

Ingredients
- 6 oz dark chocolate (60–70%) (chopped)
- 3/4 cup unsalted butter
- 3 large eggs
- 1 1/4 cups granulated sugar
- 1/2 cup brown sugar (packed)
- 1 tsp vanilla extract
- 3/4 cup all-purpose flour
- 1/4 cup unsweetened cocoa powder
- 3/4 tsp fine salt
Equipment
- 8×8-inch metal pan
- Parchment paper
- Hand mixer
Instructions
Heat the oven to 350°F (175°C). Line an 8×8-inch metal pan with parchment, leaving overhang.
Melt the chocolate and butter together in short microwave bursts, stirring between each. Cool slightly.
Beat the eggs, both sugars and vanilla on high for a full minute, until pale and foamy.
Tip: This is the crackly-top step — don't shortcut it.
Whisk the warm chocolate into the egg mixture. Fold in the flour, cocoa and salt just until combined.
Bake 26–30 minutes, until a toothpick shows moist crumbs. Cool completely before lifting out and cutting.
Storage
Airtight at room temperature up to 4 days — they're fudgier on day two.
Freezing
Freeze cut squares up to 3 months; thaw at room temperature 30 minutes.
Reheating
10 seconds in the microwave for warm, molten centers.
Substitutions
- Dark chocolate: Semisweet chips in a pinch — slightly sweeter, still fudgy.
Common mistakes
- Baking in a glass pan without adjusting — Glass insulates: add 3–5 minutes and expect softer edges.
- Cutting warm — Wait at least an hour — or chill 20 minutes for perfectly clean squares.

Frequently asked questions
How do I know when brownies are done?
A toothpick near the center should come out with moist crumbs and a smear of fudge — a clean toothpick means they're overbaked. They firm up substantially while cooling.
Why didn't I get a crackly top?
The eggs and sugar weren't whipped long enough. A full minute at high speed, until pale and slightly foamy.
