Ingredients:

  • 1/2 cup (65g) all-purpose flour
  • 1/3 cup (30g) unsweetened cocoa powder
  • 1/3 cup (65g) granulated sugar
  • 1/2 tsp (2g) baking soda
  • 1/4 tsp (1g) salt
  • 1/3 cup (80ml) buttermilk
  • 2 tbsp (28g) melted unsalted butter
  • 1 large egg yolk
  • 1/2 tsp (2.5ml) vanilla extract
  • 2 oz (55g) semi-sweet chocolate, chopped
  • 2 tbsp (30ml) heavy cream

Instructions:

  1. Grease two 4-inch ramekins with butter and dust with a pinch of cocoa powder to prevent sticking.
  2. Sift the flour, cocoa powder, sugar, baking soda, and salt into a medium mixing bowl to remove lumps.
  3. Whisk in the buttermilk, melted butter, egg yolk, and vanilla extract. Stir until just combined, stopping as soon as the flour streaks disappear.
  4. Divide the batter evenly between the two prepared ramekins.
  5. Bake at 350°F (175°C) for 18-22 minutes, or until a toothpick inserted in the center comes out with a few moist crumbs.
  6. Heat the heavy cream in the microwave until simmering, then pour it over the chopped semi-sweet chocolate.
  7. Let the chocolate and cream sit for 2 minutes, then stir until glossy and smooth.
  8. Pour the glaze over the cooled cakes for a mirror-like finish.
