3/4 cup + 2 Tbsp. packed light or dark brown sugar
1 large egg
1 tsp. vanilla
3/4 tsp. baking soda
1/4 tsp. salt
1 3/4 cups all-purpose flour
1/2 lb semi- or bittersweet chocolate, cut into rough chunks
flaky sea salt, to finish (optional)
1Heat oven to 350°F.
2In a large bowl, beat the butter and sugars together with an electric mixer until very light and fluffy, about 5 minutes. Beat in the egg and vanilla, scraping down the bowl as needed. Beat in the salt and baking soda, then the flour on a low speed until just mixed. Add the chocolate chunks, along with all the tiny bits.
3Scoop large balls of dough onto a parchment-lined baking sheet and if you like, sprinkle each with a pinch of sea salt. Bake for 12-14 minutes, until golden but still soft and gooey in the middle.
