Preheat oven to 350 degrees F and line two cookie sheets with parchment.

In the bowl of a stand mixer with the paddle attachment, beat butter for three minutes until pale. Add oil and beat again to combine.

Add the sweetener and beat for two minutes.

Add vanilla and mix to combine. Scrape bowl and beat once.

With mixer running add one egg at a time, mixing before adding the second. Scrape the bowl and mix again.

In a separate bowl, whisk Low Carb Baking Flour, cocoa, salt and baking powder and slowly add that to the contents of the mixer with the speed on low. Scrape and mix again.

Add the chocolate chips and mix for a few seconds to combine.

Using a one-ounce scoop, scoop out 24 cookies, 12 per pan.

Bake one pan at a time on the upper most rack for 15 minutes. Remove and slide the parchment and cookies onto a rack to cool. Repeat for the second pan.

Cool and store in a zipper bag with the air squeezed out.
