Add all ingredients except for the chocolate chips to a bowl and mix together until combined. Fold in chocolate chips.
Spray a 10 inch skillet with oil. A cast iron skillet works best for this. Add batter to the skillet and and spread until it is an even layer. Top with additional chocolate chips. It will seem thin but will puff up in oven. Be warned it will look a little lumpy and weird at first but after baking the lumps dissolve.
Bake for 20-30 minutes, until a toothpick comes out clean. I baked mine for 25 minutes. The cookie will seem a little cake like and won't be hard.
Let cool, top with flaky sea salt divide out and serve with ice cream (optional but recommended).
Notes
This skillet has a soft cookie dough like texture, it is not crisp like a traditional cookie.Nutritional information is for ⅛ of the recipe which is a small serving.If you want a completely smooth texture you can blend the cottage cheese but I skipped this. The lumps dissolve in the oven.
