Preheat oven to 325 degrees F. Use a silicone muffin pan or prep a 12 tin muffin pan using muffin liners or non-stick spray and set aside.
Add eggs, cottage cheese, cheddar cheese, salt, and pepper to a high speed blender. Blend until smooth, about 30 seconds.
Divide blended egg and cottage cheese mixture into pan evenly. Sprinkle in optional add-ins into each cup and mix gently if desired.
Bake 22-25 minutes until egg has set and top is very lightly golden brown.
