Prepare 2 baking sheets with parchment paper and preheat the oven to 350°F.
Add the chopped chocolate to a microwave safe bowl. Microwave in 15 second increments, stirring well between each until the chocolate is completely melted and smooth.
8 ounces chopped chocolate
Add the avocado oil to the melted chocolate and mix with a whisk until well combined. Set aside.
8 ounces chopped chocolate, ⅓ cup vegetable oil
In the bowl of a stand mixer fitted with the whisk attachment or with an electric hand mixer, beat the eggs, egg yolk, and sugar together on high speed for about 3 minutes until the color is light and pale yellow.
2 large eggs, 1 egg yolk, 1 cup cane sugar
Add the vanilla extract and melted chocolate and oil mixture to the bowl. Mix on medium until well combined.
8 ounces chopped chocolate, ⅓ cup vegetable oil, 1 teaspoon vanilla extract
Stop the mixer and add the flour, cocoa powder, and salt. Start the mixer and mix on low until just combined. Fold in the chocolate chips with the mixer on low or a rubber spatula. The dough will be soft and wet.
¾ cup all purpose flour, ¼ cup unsweetened cocoa powder, ½ teaspoon sea salt, ½ cup chocolate chips
Using a large cookie scoop, drop the cookie dough onto the prepared baking sheets with about ½ inch between each cookie dough ball.
Bake for 10-12 minutes until the edges have set and the tops are crackled. Allow the cookies to cool for 5 minutes on the tray before transferring to a wire cooling rack. Allow them to cool completely, sprinkle with flaky salt, and enjoy.
