Ingredients:
- 4 oz high-quality baking chocolate (60-70% cacao), finely chopped
- 0.25 cup unsalted butter, plus more for greasing
- 1 large egg
- 1 large egg yolk
- 2 tbsp granulated sugar
- 1 pinch fine sea salt
- 1 tbsp all-purpose flour
- 1 tbsp unsweetened cocoa powder (for dusting)
Instructions:
- Preheat your oven to 425°F (218°C). This high heat is non negotiable for getting the right contrast between the shell and the core.
- Generously butter two 6 oz ramekins, making sure to hit every nook and cranny. Sift cocoa powder into each, rotate to coat the internal surfaces completely, and tap out the excess until no white ceramic shows through. Note: This creates a non stick barrier that looks better than white flour on a dark cake.
- Combine the 4 oz finely chopped chocolate and 1/4 cup butter in a microwave safe bowl. Heat in 30 second increments, stirring until the mixture is glossy and smooth. Set this aside to cool slightly so it doesn't scramble your eggs later.
- In a separate medium bowl, use a hand mixer to beat the whole egg, egg yolk, 2 tbsp sugar, and salt at high speed for 2–3 minutes. Wait until the mixture is pale, thick, and falls in ribbons when you lift the beaters.
- Gently fold the melted chocolate mixture into the eggs using a spatula. Do this slowly so you don't knock out all the air you just worked so hard to put in.
- Sift the 1 tbsp flour over the batter and fold it in until just combined and no white streaks remain. Over mixing at this stage will make the cake tough.
- Divide the batter evenly between the prepared ramekins. Place them on a sturdy baking sheet to make them easier to move in and out of the oven.
- Bake for 8–12 minutes. You are looking for the sides to be firm while the center remains soft and slightly jiggling when you give the tray a gentle nudge.
- Let the cakes rest for exactly 1 minute. This allows the structure to firm up just enough to survive the flip.
- Carefully run a thin knife around the edges, place a dessert plate on top of the ramekin, and invert. Lift the ramekin slowly until the cake slides out and releases its steam.
