Preheat oven – Set your oven to 350°F (175°C) and line a 12-cup muffin tin with liners or grease well.
Blend wet ingredients – In a blender, combine eggs, cottage cheese, avocado oil, vanilla extract, and maple syrup. Blend until smooth.
Mix dry ingredients – In a large bowl, whisk together oat flour, grated carrots, ground flaxseed, cinnamon, baking powder, and baking soda.
Combine wet & dry – Pour the blended wet ingredients into the dry ingredients. Stir gently until just combined (the batter will be thick!).
Fill muffin cups – Evenly divide the batter among the 12 muffin cups (or 16 if making smaller muffins).
Bake – Bake for 18-22 minutes, or until a toothpick inserted in the center comes out clean.
Cool & enjoy – Let cool for a few minutes before serving.
