1 ½cupschocolate chips and/or chopped chocolateI use a combination: ½ cup semi-sweet chocolate chips, 1 cup chopped bittersweet chocolate
flaky sea salt, optional
Instructions
Mix the oil, brown sugar, and granulated sugar together with an electric mixer.
Add the egg and egg yolk and mix until creamy. Mix in the vanilla.
Stir the flour, salt, and baking soda together in a separate bowl. Mix the flour mixture into the wet ingredients a little at a time until just incorporated. Do not overmix.
Set aside a handful of chocolate chips and chopped chocolate for adding to the tops of the cookies. Fold the remaining chocolate into the dough with a wooden spoon or sturdy spatula.
Refrigerate the cookie dough for at least an hour. I prefer to chill it overnight.
Preheat the oven to 350 degrees. Line a baking sheet with parchment paper or silicone baking mats.
Portion dough into 2-3 tablespoon cookie dough balls. Place them at least 2 inches apart on the cookie sheet.
Add a few chocolate chips and chopped chocolate pieces to the top of each cookie ball. If desired, sprinkle with flaky sea salt.
Bake for 9-11 minutes or until the top of the cookies just start to turn light golden brown. Be careful not to overbake.
Cool cookies on the pan for 10 minutes, then transfer to a cooling rack to cool the rest of the way.
Notes
Use extra-virgin olive oil if you want the unique flavor of olive oil in your cookies. If you prefer not to taste it, a neutral vegetable oil like canola oil is perfect.Try using all brown sugar. The rich toffee caramel flavor is absolutely delicious!Chill the dough. This dough is very soft and it needs to be chilled until firm -- at least an hour or more. I usually chill the dough overnight.Use a variety of chocolate chips and chopped chocolate to add texture and flavors.
