Prepare oven and baking pan: Move your oven rack to the middle position and pre-heat oven to 375 F. Spray a 9x9 inch baking pan with cooking spray or line with parchment paper.
Whisk dry ingredients: In a large bowl, mix together oats, protein powder, baking powder, cinnamon, and salt. Set aside.
Blend wet ingredients: Add eggs, milk, cottage cheese, olive oil, maple syrup, and vanilla extract to a blender. Blend until smooth, about 10-15 seconds.
Combine wet and dry ingredients: Pour wet ingredients over dry ingredients and mix with a wooden spoon or spatula until combined.
Pour into pan: Pour batter into baking pan and use the back of your spoon/spatula to flatten batter and evenly distribute oats if necessary.
Bake: Bake for 20-25 minutes or until a toothpick comes out clean, with just a few moist crumbs. Cook until baked oats are completely set and golden brown.
Cool, slice, and enjoy: Allow oats to cool for a minimum of 10 minutes before slicing. Add toppings and enjoy!
