Making Zucchini Carrot Oatmeal Muffins is a simple process. Follow these steps for perfect results:

1. Preheat the Oven: Preheat your oven to 350°F (175°C). Line a muffin tin with paper liners or grease with cooking spray.
2. Prepare the Vegetables: Grate the zucchini and carrots using a box grater. Make sure to squeeze out excess moisture from the zucchini using a clean kitchen towel.
3. Combine Dry Ingredients: In a large mixing bowl, combine rolled oats, flour, brown sugar, granulated sugar, baking powder, baking soda, salt, cinnamon, and nutmeg.
4. Mix Wet Ingredients: In another bowl, whisk together the eggs, vegetable oil, and vanilla extract until fully combined.
5. Add Vegetables: Stir in the grated zucchini and carrots into the wet mixture.
6. Combine Mixtures: Pour the wet ingredients into the dry ingredient bowl. Stir until just combined, being careful not to overmix. If desired, fold in chopped nuts or chocolate chips at this stage.
7. Fill Muffin Cups: Spoon the batter into the prepared muffin tin, filling each cup about ¾ full.
8. Bake: Place in the preheated oven and bake for 20-25 minutes, or until a toothpick inserted comes out clean.
9. Cool: Once done, remove from the oven and let the muffins cool in the tin for 10 minutes. After that, transfer to a wire rack to cool completely.

With these steps, you’ll have delicious, healthy muffins ready to be enjoyed by everyone!
