Preheat your oven to 350°F and line a large baking sheet with parchment paper.
Grate the carrot and the half gala apple using the fine holes of a box grater.
In a large mixing bowl, whisk the two whole eggs and the egg whites together until the mixture is light and frothy.
Stir in the rolled oats, grated carrot, grated apple, lemon zest, honey, cinnamon, baking soda, sea salt, raisins, and cacao powder until well combined.
Allow the batter to sit for 5 to 10 minutes so the oats can absorb the moisture and soften.
Using a small spoon or cookie scoop, portion the batter into 20 small mounds on the prepared baking sheet.
Bake for 12 to 15 minutes until the cookies are set and firm to the touch.
Remove from the oven and let the cookies cool completely on a wire rack before enjoying.
