Ingredients for the Zucchini Carrot Oatmeal Muffins
- 1 cup grated zucchini (excess moisture squeezed out)
- 1 cup grated carrots
- 1 cup rolled oats
- 1 cup all-purpose flour
- 1/2 cup brown sugar
- 1 tsp baking powder
- 1/2 tsp baking soda
- 1 tsp ground cinnamon
- 1/4 tsp ground nutmeg
- 1/4 tsp salt
- 2 large eggs
- 1/3 cup vegetable oil
- 1 tsp vanilla extract
- Optional: 1/2 cup raisins, chopped walnuts, or shredded coconut

How To Make the Zucchini Carrot Oatmeal Muffins
Step 1: Prep Your Veggies
Start by grating the zucchini and carrots using a box grater. There’s no need to peel either vegetable. After grating, use a clean kitchen towel or cheesecloth to squeeze out excess moisture from the zucchini—this helps avoid soggy muffins.
Step 2: Mix the Dry Ingredients
In a large mixing bowl, combine rolled oats, all-purpose flour, baking powder, baking soda, cinnamon, nutmeg, and salt. Stir everything together until well incorporated.
Step 3: Whisk the Wet Ingredients
In another bowl, whisk together the eggs, brown sugar, vanilla extract, and vegetable oil until smooth and slightly frothy. This forms the base of the muffin batter.
Step 4: Combine the Wet and Dry Mixtures
Make a well in the center of your dry ingredients and pour in the wet mixture. Stir until just combined—avoid overmixing, which can make the muffins dense.
Step 5: Fold in the Veggies
Gently fold in the grated zucchini and carrots. If you’re using add-ins like raisins or chopped nuts, stir them in now.
Step 6: Fill the Muffin Cups
Line a muffin tin with paper liners or grease with non-stick spray. Divide the batter evenly among the cups, filling each about 3/4 full.
Step 7: Bake to Perfection
Preheat your oven to 350°F (175°C). Bake the muffins for 20-25 minutes or until a toothpick inserted into the center comes out clean. Let them cool in the tin for 5 minutes before transferring to a wire rack.
Best Ways to Serve and Store These Muffins
Zucchini Carrot Oatmeal Muffins are best served slightly warm or at room temperature. They’re delicious on their own, but even better with a pat of butter, a smear of almond butter, or a drizzle of honey. Pair them with a hot cup of coffee or a green smoothie for a complete breakfast.
To store, place fully cooled muffins in an airtight container. They’ll stay fresh at room temperature for up to 3 days. For longer storage, keep them in the fridge for up to a week or freeze for up to 3 months. Reheat in the microwave for about 20 seconds or thaw overnight in the refrigerator.
Frequently Asked Questions
How do I prevent the muffins from becoming soggy?
Make sure to squeeze out the excess moisture from the zucchini after grating. Also, don’t overmix the batter, as that can lead to dense and heavy muffins.
Can I make these muffins gluten-free?
Yes! Substitute the all-purpose flour with a 1:1 gluten-free flour blend, and ensure your oats are certified gluten-free.
Can I reduce the sugar in the recipe?
Absolutely. You can reduce the brown sugar by up to 1/3 cup if you prefer a less sweet muffin. Keep in mind this may slightly change the texture.
Are these muffins suitable for kids?
Definitely. They’re soft, easy to eat, and a great way to sneak veggies into a child’s diet. You can even make mini muffins for smaller hands.
Can I add protein powder?
Yes, you can replace 1/4 cup of the flour with your favorite protein powder. Make sure it’s a mild or complementary flavor.
What are some optional mix-ins?
Try raisins, chopped walnuts, pecans, shredded coconut, or even mini chocolate chips for a bit of indulgence.
