Preheat oven to 350 degrees. Line 6 muffin cups with parchment paper or spray with cooking spray.
In a food processor, place the carrots and spinach. Process for 30 seconds, scrape down sides and process another 30 seconds or until carrots are in small pieces.
Scoop out carrots and spinach into a mixing bowl. Add eggs, flour, sea salt, onion and garlic powder, and fresh rosemary. Stir all ingredients together.
Scoop batter evenly into 6 muffin cups. Bake in the oven for 20-25 minutes.
Remove from oven. Let cool slightly before serving.
Store leftovers in an airtight container for up to 4 days. May freeze in a freezer baggie/container for up to one month.
