Preheat the oven to 350F (180C). Line an 8x8" baking pan with a silicone mat or parchment paper.

Combine the egg, almond butter, and almond milk together in a bowl. Set aside.

In a stand mixer, combine the almond flour and sweetener. Add in the egg mixture and beat until fully mixed. It will form a very thick dough.

Stir in the low carb chocolate chips. Press the mixture into the prepared pan.

Bake for 20-25 minutes or until cooked through. It will be very soft when you remove it from the oven, so let it cool in the pan for at least 15 minutes before transferring it carefully to a cooling rack.

Let the cookie bars cool completely then cut into 16 squares.
