Instructions
- Prep the pan & ovenPreheat oven to 170°C (340°F).Line the bottom of the pan with baking paper and lightly grease the sides.
- Melt chocolate & butterIn a heatproof bowl, melt chocolate and butter together over a double boiler or in the microwave (short bursts, stirring in between).Let cool slightly.
- Beat yolks & sugarIn a large bowl, whisk egg yolks with sugar until pale and creamy.Stir in vanilla (if using) and the melted chocolate-butter mixture.
- Add almondsFold in ground almonds until fully combined.
- Whip egg whitesIn a separate bowl, beat egg whites with a pinch of salt until stiff peaks form.Gently fold into the chocolate-almond mixture in batches to avoid deflating the batter.
- BakePour batter into prepared pan and smooth the top.Bake for 35–40 minutes, until the top is set and a toothpick inserted near the center comes out with moist crumbs (not wet batter).
- CoolLet cool in pan for 15 minutes, then transfer to a wire rack.Cool completely before dusting with powdered sugar.
Notes
Do not overbake. The center should remain moist and slightly fudgy, like a brownie. A toothpick should come out with a few moist crumbs, not completely clean.
Cool completely before serving. The texture improves as it cools even better the next day.
Use high-quality chocolate. The flavor of the cake depends heavily on the chocolate you use. Go for bittersweet or dark chocolate (at least 70% cocoa) for that rich, intense flavor.
Separate the eggs carefully. Even a little yolk in the whites can prevent them from whipping properly.
Fold whites in gently. This step gives the cake its lightness. Use a spatula and fold in three stages to avoid deflating the batter.
Ground almonds vs. almond flour: Either works. Almond flour will give a finer texture, while ground almonds may leave a bit more bite.
Butter: Use unsalted butter. If using salted, reduce the pinch of salt in the recipe.
