Preheat oven to 425 degrees F and adjust the oven rack to the upper-middle position. Grease four 4-ounce ramekins with butter, then coat with granulated sugar, tapping out the excess.
In a large bowl, whisk together the sugar and cornstarch.
In a medium heatproof bowl set over a pan of barely simmering water, melt the butter and chocolate together.
Add the chocolate mixture to the sugar mixture and whisk to combine. Add the eggs, egg yolks, and vanilla extract, and whisk until thoroughly combined.
Divide the batter between the prepared ramekins, place them on a rimmed baking sheet, and bake until the tops are set and look shiny on top, 13 to 16 minutes.
Remove from the oven, cool for 2 minutes, then run a paring knife around the edges of the ramekins. Carefully invert each cake onto a plate and serve immediately.
