Preheat the oven to 180C/350F. Line an 8-inch square pan.
In a large mixing bowl, add the oats, cocoa powder, and salt, and mix well. In a separate bowl, whisk together the egg, coconut oil, applesauce, and maple syrup.
Combine the wet and dry ingredients until combined. Fold through the chocolate chips.
Bake for 15-20 minutes or until a toothpick comes out just clean. For gooey baked oatmeal, remove at the 15-minute mark. Let the baked oatmeal cool in the pan completely before slicing and serving.
