3 ounces/85 grams high quality bittersweet chocolate, 70 to 74 percent cacao (not chips), chopped (about ½ cup), Ghiradelli, Schaffen Berger
3 tablespoons unsalted butter, cut into cubes, plus more for the ramekin
3 tablespoons granulated sugar, plus more for the ramekin
1 large egg
1 large egg yolk
½ teaspoon vanilla extract
⅛ teaspoon kosher salt
2 tablespoons all-purpose flour
Confectioners’ sugar, to serve (optional)
Heat oven to 425 degrees and butter two ramekins. Dust the buttered ramekins with granulated sugar.
Chop the chocolate into small thin chunks. Combine the chocolate and 3 tablespoons butter in a heat-safe bowl set over a pan of simmering water. Cook, stirring occasionally, until melted and smooth. (Alternatively, combine in a bowl and microwave in 30-second blasts, stirring in between, until melted and smooth, about 1 minute.) Remove from the heat and set aside.
In a medium bowl, combine the 3 tablespoons sugar, egg, egg yolk, vanilla and salt. Whisk vigorously until the mixture is thick, foamy and pale, about 2 minutes. Whisk in the flour until smooth.
Using a spatula, add the chocolate to the egg mixture and stir gently until combined.
Pour the mixture into the ramekin. Bake for 12 to 14 minutes or until the edges are set and puffed, but the center is still soft when lightly pressed. (You can also cover and refrigerate the batter up to a day in advance. Add an additional minute or 2 to baking time if you are baking the cake directly from the refrigerator.)
Use an offset spatula or small knife to loosen the edges of the cake from the ramekin. Place a plate over the ramekin and carefully invert the warm cake. Use an oven mitt or clean kitchen towel to remove the ramekin, dust the cake with confectioners’ sugar and serve immediately with ice cream or whipped cream. You can also store these in the fridge for up to three days or in the freezer for up to one month.
