High cocoa butter melts into an unctuous fluid core. • 📍 Baking aisle.
Brush four 6-oz ramekins with softened butter and dust evenly with unsweetened cocoa powder. Melt chopped 70% dark chocolate and remaining butter in 30-second bursts until glossy and smooth.
✓ Checkpoint: Cocoa-dusted ramekins and velvety warm ganache.
Whisk 2 whole eggs, 2 egg yolks, 0.5 cup powdered sugar, vanilla extract, and fine kosher salt until pale, thick, and frothy.
✓ Checkpoint: Airy pale egg foam.
Fold the warm melted chocolate into the egg foam, then gently sift and fold in the all-purpose flour until smooth.
✓ Checkpoint: Rich, glossy batter.
Divide batter among the prepared ramekins and bake at 425°F (220°C) for 12 minutes until the edges set firm and the molten center reaches 160°F (71°C). Invert onto warm plates and dust with powdered sugar.
✓ Checkpoint: Molten river flowing from cake center.
Precise Thermal Dynamics: High-heat baking at 425°F (220°C) sets the outer cake walls rapidly while bringing the fluid chocolate-egg center to 160°F (71°C) before it solidifies.
Center baked solid: Pull from oven at 11-12 minutes; center must retain a visible jelly-like wobble.
