In a bowl, add the applesauce, liquid sweetener of your choice, ricotta cheese, vanilla, egg , and mix together.
Add the ground oats, cornstarch, baking powder and salt, and mix using a spatula until a smooth cookie batter is formed. Make sure there are no lumps on the bottom of the bowl.
Stir in the dark chocolate and pour into a greased skillet, and spread evenly. Sprinkle with chocolate chips on top.
Bake at 350F (180C) for 16-20 minutes.
Let it cool for 10 minutes, then dig in straight from the skillet, or cut into slices and serve individually.
