Prep the pan: Preheat the oven to 350°F (175°C). Lightly grease a 24-cup mini muffin pan or line with mini liners.
Whisk the wet ingredients: In a large bowl, whisk the egg, oil, Greek yogurt, brown sugar, and vanilla until smooth and slightly fluffy.
Add the carrots: Stir in the grated carrots.
If they’re very wet, lightly blot with a paper towel first to avoid excess moisture.
Combine dry ingredients: In the same bowl, sprinkle in the flour, baking powder, baking soda, cinnamon, nutmeg, and salt. Gently fold until just combined. Do not overmix.
Stir in extras (optional): Fold in nuts, raisins, or coconut if using.
Keep add-ins modest to maintain the calorie target.
Fill the pan: Divide the batter evenly among cups, about 1 heaping tablespoon each. They should be around 3/4 full.
Bake: Bake for 10–12 minutes, or until the tops spring back and a toothpick comes out clean or with a few moist crumbs.
Cool: Let the bites cool in the pan for 5 minutes, then transfer to a wire rack to cool completely.
Optional glaze: Beat cream cheese, powdered sugar, milk, and a pinch of salt until smooth. Drizzle lightly over cooled bites for a classic carrot cake finish.
