Preheat oven to 350 degrees F. or 180 C.
I use parchment paper, overlapping pan and spray with baking spray for an 8 x 8 brownie pan.
Mix dry ingredients: almond flour, coconut flour: baking powder, baking soda, salt, xanthan gum. Set aside.
Beat eggs in mixer.
Stream oil in while mixer is running. This emulsifies the oil to the eggs.
Add Swerve or erythritol of choice.
In separate bowl mix cocoa powder, with boiling water. It may be thick and that's okay. The boiling water blooms the powders for extra flavor.
Add in sour cream to cocoa mixture, as cocoa mixture will be quite thick.
Add this cocoa mixture to egg mixture.
Add in dry mixture, and mix just until mixed. Do not over-mix.
Add in chocolate chips.
Pour batter into prepared pan. Smooth out.
Add Cream Cheese Mixture below.
Using a scoop, place the cream cheese mixture over the batter evenly. Use a knife to swirl. Top with remaining chocolate chips.
Bake for approximately 30 minutes until the inside temperature in middle reaches about 200 degrees F for fudgy and no more than 207 Degrees or brownies will be over-baked.
Cool Completely before cutting. Keep refrigerated. These tastes best served cold.
