Step 1

Arrange racks in the upper and lower thirds of the oven and preheat to 350 degrees F. Line 2 baking sheets with parchment paper.

Step 2

Whisk the flour, salt and baking soda in a medium bowl until completely combined. Beat the butter, oil, granulated sugar and brown sugar in the bowl of a stand mixer with the paddle attachment (or a large bowl if using a hand mixer) on medium-high speed until creamy, about 5 minutes. The mixture will look broken but that's ok. Beat in 1 teaspoon water and the vanilla until smooth. Reduce the speed to low and beat in the eggs one at a time until incorporated. Beat in the dry ingredients until just combined. Fold in 1 1/2 cups chocolate chips. Reserve the rest.

Step 3

Drop heaping tablespoons of the dough onto the prepared baking sheets about 2 inches apart. Lightly press about 3 of the remaining chocolate chips into each cookie.

Step 4

Bake the cookies until they are a deep golden brown, rotating the pans halfway through, 12 to 15 minutes. Let the cookies cool on the baking sheets for 10 minutes. Then transfer them to a wire rack to cool completely. Repeat with any remaining dough.
