Direction

1. Place racks in center of upper third of oven; preheat to 350º. In a large bowl, using a handheld mixer on medium-high speed, cream brown sugar, granulated sugar, and oil until incorporated, about 2 minutes. Beat in eggs and egg yolk, one at a time, beating to blend after each addition. Add orange zest (if using) and vanilla and beat just to combine.
2. Add all-purpose flour, whole wheat flour, baking soda, and kosher salt and beat on low speed until dry ingredients are halfway combined, about 30 seconds. Fold in chips and chopped chocolate with a rubber spatula and stir until combined and no dry streaks remain.
3. Scoop out 1 1/2" balls (about 2 tablespoons each) and arrange on 2 parchment-lined baking sheets (6 balls per sheet), spacing about 2" apart.
4. Bake cookies, rotating sheets halfway through, until puffed up and golden around the edges, 10 to 12 minutes. Sprinkle hot cookies with sea salt.
