Heat oven to 350 degrees F and line a large baking sheet with parchment paper.
In a large bowl, beat sugars, butter (if cold, in chunks), and salt together until fluffy.
Add egg and vanilla, and beat until mixed.
Sprinkle baking powder and baking soda over batter and beat until very well-combined.
Scrape bowl down. Add flour, wheat germ, oats, and chocolate and mix just until the flour disappears.
Arrange 3-tablespoon mounds of cookies 3 inches apart on the baking sheet.
Sprinkle each with a couple flakes of sea salt.
Bake for 12 to 14 minutes until cookies are golden brown all over.
Remove from oven and let set up on the baking sheet for 5 minutes before transferring them to a cooling rack.
Extra dough can be kept in the fridge for 3 days or longer in the freezer.
