Why You’ll Love These Zucchini Carrot Oatmeal Muffins
These muffins are soft, cozy, and just sweet enough—thanks to brown sugar and naturally sweet carrots. They’re loaded with good-for-you oats and veggies, but still taste like a treat. Plus, they’re easy to mix up, freeze like a dream, and my kids devour them faster than I can say “hidden zucchini.”
They make a perfect grab-and-go breakfast, after-school snack, or lunchbox filler. You can even dress them up with a dollop of nut butter or a sprinkle of granola on top!
Ingredients You’ll Need

Core Ingredients
We’re keeping things simple and wholesome here:
- Whole wheat flour gives a nutty, hearty base.
- Old-fashioned oats soak in milk for a tender crumb.
- Zucchini and carrots, shredded and snuck in for moisture and nutrients.
- Egg, brown sugar, melted coconut oil, and vanilla bring it all together for flavor and structure.
Optional Add-ins & Substitutions
Feel free to get creative:
- Golden raisins add little bursts of sweetness.
- Want crunch? Toss in some chopped walnuts or pecans.
- Swap the flour for gluten-free blend if needed.
- Use maple syrup instead of sugar for a refined-sugar-free version.
- Applesauce works great in place of oil if you’re going low-fat.

How to Make Zucchini Carrot Oatmeal Muffins
Step-by-Step Instructions
- Preheat your oven to 375°F. Line your muffin tin or give it a good spray.
- Soak the oats: Stir oats and milk together and let them sit while you prep the rest.
- In a separate bowl, whisk the dry stuff—flour, baking powder, baking soda, cinnamon, and salt.
- In another bowl, combine the wet: egg, sugar, oil, and vanilla.
- Mix the oat-milk mixture with the wet ingredients, then fold in your shredded veggies.
- Gently stir wet into dry, just until combined. Fold in raisins if you’re using them.
- Scoop the batter into muffin cups—about ¾ full—and bake 18–22 minutes.
Pro Tips for Best Results
- Don’t overmix the batter—lumpy is lovely!
- Squeeze excess liquid from zucchini only if it’s extra watery.
- Use the toothpick test: poke one in the center and if it comes out clean, you’re golden.
Storage and Freezing Tips
Let muffins cool completely before storing. You can:
- Keep them in an airtight container at room temp for 2–3 days.
- Refrigerate up to 1 week.
- Freeze for up to 2 months—just thaw overnight in the fridge or microwave for 20 seconds.
