Preheat the oven to 350 F and lightly grease an 8-inch square baking dish.
Blend the cottage cheese, eggs, banana, peanut butter, maple syrup, cocoa powder, baking powder, vanilla, and salt until smooth.
Add the rolled oats and blend for 10 seconds, just until some of the oats are broken down but the mixture still has a little texture.
Stir in half of the chocolate chips and pour the batter into the prepared baking dish.
Sprinkle the remaining chocolate chips over the top.
Bake for 28 to 32 minutes, until the center is set but still slightly soft.
Cool for 10 minutes before slicing so the baked oats become fudgy and tender.
