Preheat oven to 350°F (175°C). Lightly butter a 10-inch (25 cm) cast-iron or oven-safe skillet; line the bottom with a round of parchment if desired. In a large bowl, whisk melted butter, brown sugar, and granulated sugar until smooth and glossy, about 1 minute. Whisk in the egg, egg yolk, and vanilla until well combined. In a separate bowl, whisk together flour, baking soda, and salt. Add dry ingredients to the wet and fold just until a thick dough forms; do not overmix. Fold in the chocolate chips. Scrape dough into the prepared skillet and press into an even layer. Sprinkle a few extra chips on top and a pinch of flaky sea salt if using. Bake 20–25 minutes, until the edges are deep golden and the center is set but still soft; a toothpick inserted 2 inches (5.08 cm) from the edge should come out with a few moist crumbs. For extra-gooey, bake closer to 20 minutes; for sliceable, 23–25 minutes. Cool in the skillet on a rack for 10–15 minutes. Serve warm straight from the skillet with scoops of vanilla ice cream, if desired.
