1. To make the chocolate brownie cookies: Adjust your oven racks to the middle position and preheat your oven to 300ºF (150ºC). Line two rimmed baking sheets with parchment paper.

2. Whisk flour, cocoa, baking powder, baking soda, and salt together in a large bowl and set aside.

3. Microwave 2/3 of the chocolate chips, oil, and butter in a medium bowl at 50 percent power, stirring halfway through with a wooden spoon, until melted, about 3 minutes. Whisk the milk into the chocolate mixture until fully combined and smooth.

4. Using a stand mixer or hand mixer, whip sugar and eggs on medium-high speed until very thick and pale. Add the melted chocolate mixture and whisk by hand until smooth.

5. Fold in the flour mixture using a spatula until well combined. Fold in the remaining 1/3 of chocolate chips and chopped pecans, if using.

6. Using a tablespoon or a cookie scoop, divide portions of the cookie dough onto the prepared baking sheets – you should get 20 cookies total. Bake in the oven until the chocolate brownie cookies are puffed and covered with large cracks, about 15 minutes, rotating the baking sheets halfway through baking to ensure even cooking for all cookies.

7. Let the chocolate brownie cookies cool completely on the baking sheets, about 30 minutes. Sprinkle with kosher salt. Enjoy! ❤️
