In a medium sized bowl, whisk together the sugars and egg until light and fluffy, about 2-3 minutes.
Add the salt and vanilla and whisk to combine.
While whisking, slowly pour in the olive oil. Once it’s all in, whisk vigorously until you have a smooth shiny mixture.
Add the flour and baking soda, and stir until it’s half combined. Add the chocolate and stir until the dough is mixed and no flour streaks remain.
Cover the bowl with plastic wrap to seal and leave on the counter for 30-60 minutes. This time is essential for the flour to hydrate. After this you have the option to transfer the bowl to the fridge and chill overnight.
Preheat the oven to 350 F. Line two greased baking sheets with parchment paper.
Use a 1.5 or 2 tablespoon cookie scoop to portion the dough. Leave a 1 inch diameter around each dough ball so the cookies can spread.
Bake until the edges are golden and the center is set, depending on the size of your cookies this can take 10-12 minutes (13 if you like dark brown crispy edges).
Let cool on the pan for a few minutes, then transfer to a plate.
Once completely cool, store in an airtight container.
