Add the softened butter, granulated sugar, and light brown sugar to a mixing bowl. Using a stand mixer or hand mixer, beat the mixture for about 5 minutes until light and fluffy. Add the vanilla extract and mix until just combined.
02 -
Scrape down the sides of the bowl with a rubber spatula. With the mixer on low speed, gradually add the flour to the creamed mixture until fully combined.

Add the dark chocolate chips and fresh orange zest to the dough. Continue mixing until the dough is smooth and cohesive.

Divide the dough into two equal portions. Place each portion onto plastic wrap and shape into a circular log. Wrap tightly in the plastic wrap.
05 -
Refrigerate the dough logs for at least 2 hours or overnight to firm up.
06 -
Approximately 10 minutes before the dough is finished chilling, preheat the oven to 350°F (175°C).
07 -
Remove one log of dough from the refrigerator and unwrap it. Brush it lightly with egg wash, then roll it in turbinado sugar until evenly coated.
08 -
Using a sharp knife, slice the log into rounds, each 1/2 inch thick. Ensure uniform thickness for even baking.
09 -
Arrange the slices on a lined baking sheet, spacing them evenly. Bake in batches for 12-14 minutes or until the edges are just slightly browned. Let the cookies cool on the pan for 10 minutes before transferring to a cooling rack.

Sprinkle the cooled cookies with additional orange zest and flaky sea salt. If desired, drizzle melted dark chocolate on top for added flavor.

Repeat the rolling, slicing, and baking process with the remaining dough log. Enjoy the cookies!
