Ultimate Paper-Thin Crinkle Fudgy Brownies

Dense brownies with a glossy, delicate crust created by dissolving sugar well and thoroughly combining warm fat, chocolate and eggs.

Ingredients

• 170 g unsalted butter
• 170 g 70% dark chocolate, chopped
• 250 g granulated sugar
• 2 large eggs plus 1 yolk
• 1 tsp vanilla extract
• 75 g all-purpose flour
• 30 g Dutch-process cocoa powder
• 1/2 tsp fine salt

Method

1. Heat oven to 175°C/350°F. Line the pan with parchment.
2. Melt butter and chocolate gently, then whisk in half the sugar while warm.
3. Whisk eggs, yolk, remaining sugar and vanilla until slightly thickened, then slowly whisk in the chocolate mixture.
4. Fold in flour, cocoa and salt only until no dry streaks remain.
5. Bake until the edges are set and the centre gives moist crumbs on a skewer. Cool completely before slicing.

Why this formulation works

Sufficient dissolved sugar and egg proteins help form the fragile surface film, while the relatively low flour level keeps the centre dense rather than cake-like.

Pan, doneness and texture

The listed pan is part of the formulation. Moving the same batter into a pan with a different base area changes average batter depth and therefore changes the relationship between edge and centre cooking. Use the pan converter before substituting a substantially different size.

For fudgy and chewy styles, a completely clean skewer can indicate that the centre has baked beyond its intended texture. Look for set edges and a centre that is no longer liquid, then allow the slab to cool before making a final texture judgement.

Recipe notes

• Do not judge doneness by a completely clean toothpick; that usually means a fudgy brownie has gone too far.
• A light-coloured metal pan gives more predictable edge-to-centre baking than glass for this formulation.

Allergens: Egg, milk, wheat. Check every packaged ingredient because formulations and cross-contact statements vary by brand.
