Fold in sweetener, Carbquik, and cocoa, beat until smooth.
Fold in chocolate chips. Pour into an 8×8 baking pan lined with parchment paper. Smooth down with a spatula.
Bake for 20 minutes at 350°F until a toothpick inserted into the center comes out clean. If you like undercooked brownies, start checking after 10 minutes for desired doneness.
