Olive oil cookies are brown sugar cookies made with olive oil instead of butter. These olive oil chocolate chip cookies have crisp edges, soft and chewy centers.
In a large mixing bowl, whisk the olive oil, brown sugar, granulated sugar, espresso powder and vanilla extract until well combined. Whisk in the egg and egg yolk until smooth and well combined.
Stir the dry ingredients into the wetuntil just combined.I like to do this about ½ of the dry ingredients at a time. Fold in most of the chopped chocolate or chocolate chips.
About 30 minutes before baking the cookies, preheat the oven to 375 F (190 C). Line a large baking sheet with parchment paper. Cover the cookies with plastic wrap and transfer to the fridge to chill for 30 minutes or up to overnight.
Using a large cookie scoop (3 tablespoons, 45 ml), scoop the olive oil chocolate chip cookie dough and place the cookie dough balls onto the lined baking sheet about 3 inches (8 cm) apart. Top with the reserved ½ cup (85 g) of chocolate chips or chunks.
