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

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.
