Preheat oven to 375°F (190°C) and liberally grease a 12-cup standard muffin tin with non-stick cooking spray.
In a large mixing bowl, combine the cooked brown rice and finely chopped broccoli florets.
Add the blended cottage cheese, beaten eggs, and 1 cup of the shredded cheddar cheese to the rice mixture.
Stir in the nutritional yeast, garlic powder, onion powder, salt, and black pepper until the mixture is uniform.
Spoon the mixture into the prepared muffin tin, filling each cup to the top and pressing down slightly with the back of a spoon to pack.
Sprinkle the remaining 0.5 cup of shredded cheddar cheese evenly over the tops of the 12 cups.
Bake for 22 to 25 minutes, or until the cheese is melted and the edges are golden brown.
Remove from the oven and allow the cups to cool in the tin for at least 5 to 10 minutes to ensure they set properly before removing.
