- Salt: Enhances all the flavors in the muffin.
- Ground cinnamon and nutmeg: Impart a warm, comforting spice profile.
- Large eggs: Bind the ingredients and add richness.
- Vegetable oil: Keeps muffins moist and tender.
- Granulated and brown sugar: Combine for balanced sweetness and depth.

How to Make Zucchini Oatmeal Muffins Recipe
Step 1: Prepare Your Baking Environment
First things first, heat your oven to 350°F (175°C) and get a 12-cup muffin tin ready. Whether you prefer paper liners or a quick spray of cooking oil, this little step makes for easy removal and cleanup later.
Step 2: Combine the Dry Ingredients
In a large bowl, whisk together all the dry ingredients—flour, oats, baking powder, baking soda, salt, cinnamon, and nutmeg. This ensures the leaveners are evenly dispersed and the spices infuse the batter with their warm aroma evenly.
Step 3: Mix the Wet Ingredients
In a separate bowl, beat the eggs and stir in the vegetable oil, both sugars, and the vanilla extract. This mixture brings the perfect balance of moisture and sweetness to your muffins.
Step 4: Add the Zucchini and Milk
Stir the freshly grated zucchini into your wet ingredients, allowing its moisture to blend in smoothly. Then pour in the milk, making the batter supple and rich.
Step 5: Combine Wet and Dry Ingredients
Gradually fold the dry ingredients into the wet mixture until just combined. Be gentle here—overmixing can make your muffins tough instead of tender, and that’s the last thing we want!
Step 6: Fold in Nuts (Optional)
If you’re a fan of a nutty crunch, now is the time to gently fold in chopped walnuts or pecans. They add wonderful texture and a toasty flavor that pairs beautifully with the zucchini and spices.
Step 7: Fill Muffin Cups
Divide your batter evenly among the muffin cups, aiming to fill each about three-quarters full. This gives the muffins room to rise to their perfect fluffy height.
Step 8: Bake to Perfection
Pop the tin in the oven and bake for 18 to 22 minutes. You’ll know they’re done when a toothpick inserted in the center comes out clean and the tops turn a lovely golden brown.
Step 9: Cool and Enjoy
Allow your muffins to rest in the pan for five minutes before transferring them to a wire rack. This little pause helps them set up and cool evenly, preserving their moistness and flavor.
How to Serve Zucchini Oatmeal Muffins Recipe

Garnishes
These muffins are delightful on their own, but a little extra can elevate them. Try a smear of creamy butter or a drizzle of honey for a sweet contrast. A sprinkle of cinnamon sugar on top right after baking adds a sparkling, sweet crust that’s irresistible.
Side Dishes
Pair your zucchini oatmeal muffins with a hot cup of coffee or a chai latte for a cozy start to your day. For lunch or snack time, fresh fruit like berries or apple slices complement the wholesome flavors perfectly. A dollop of yogurt with a sprinkle of granola can make for a more complete, nourishing meal.
Creative Ways to Present
Why not turn your muffins into mini morning parfaits by crumbling them over yogurt and layering with fresh fruit? Or put a savory spin on things by adding a slice of sharp cheddar and a thin slice of turkey for a quick sandwich twist. Your Zucchini Oatmeal Muffins Recipe definitely invites some creative serving ideas!
Make Ahead and Storage
Storing Leftovers
Once fully cooled, store your muffins in an airtight container at room temperature. They will stay fresh and delicious for 3 to 4 days, perfect for quick snacks or breakfast throughout the week.
Freezing
Want to enjoy these muffins later? Wrap them individually in plastic wrap or place them in a freezer bag, then pop them in the freezer. Frozen zucchini oatmeal muffins keep well for up to 3 months without losing texture or flavor.
Reheating
When you’re ready to eat a frozen muffin, let it thaw at room temperature or warm it gently in the microwave for 20-30 seconds. This brings back the soft, moist texture you love, as if they just came out of the oven.
FAQs
Can I use gluten-free flour in the Zucchini Oatmeal Muffins Recipe?
Absolutely! Substituting all-purpose flour for a gluten-free blend that includes xanthan gum works well. Just ensure your oats are gluten-free certified if that’s a dietary concern.
Do I need to peel the zucchini before grating?
No need to peel your zucchini. The skin is tender and adds a lovely splash of color and extra nutrients to your muffins.
Can I replace the vegetable oil with something healthier?
Yes, you can swap vegetable oil for melted coconut oil, avocado oil, or even applesauce for a lower-fat option. Just keep in mind it may slightly alter the flavor or texture.
Are these muffins suitable for kids?
Definitely! The natural sweetness from the zucchini and gentle spices make these muffins a hit with kids and adults alike. They’re an effortless way to add veggies to little ones’ diets.
How do I make these muffins more moist?
If you want extra moisture, try adding a tablespoon of Greek yogurt or sour cream to the wet ingredients. Another trick is to not overbake them—removing the muffins right when a toothpick comes out clean keeps them tender.

- 1/4 cup brown sugar, packed
- 1 teaspoon vanilla extract
- 1 cup grated zucchini (about 1 medium zucchini)
- 1/2 cup milk
Optional
- 1/2 cup chopped walnuts or pecans
Instructions
- Preheat the oven: Preheat your oven to 350°F (175°C). Line a 12-cup muffin tin with paper liners or lightly grease it with cooking spray to prevent sticking.
- Mix dry ingredients: In a large bowl, whisk together the all-purpose flour, old-fashioned oats, baking powder, baking soda, salt, ground cinnamon, and ground nutmeg until evenly combined.
- Combine wet ingredients: In a separate bowl, beat the eggs. Add vegetable oil, granulated sugar, brown sugar, and vanilla extract, mixing well until all ingredients are fully incorporated and smooth.
- Add zucchini and milk: Stir the grated zucchini into the wet mixture, then add the milk and mix until combined.
- Combine wet and dry mixtures: Gradually add the dry ingredients to the wet ingredients, stirring gently until just combined. Avoid overmixing to keep the muffins tender.
- Add nuts (optional): If using, fold in the chopped walnuts or pecans carefully to distribute them evenly throughout the batter.
- Fill muffin cups: Divide the batter evenly among the prepared muffin cups, filling each about three-quarters full to allow room for rising.
- Bake: Place the muffin tin in the preheated oven and bake for 18-22 minutes. Check doneness by inserting a toothpick into the center of a muffin; it should come out clean or with just a few crumbs attached.
- Cool: Let the muffins cool in the tin for about 5 minutes, then remove and transfer them to a wire rack to cool completely before serving.
Notes
- Make sure not to overmix the batter to maintain a light and tender texture.
- If you do not have old-fashioned oats, quick oats can be used but the texture may be slightly different.
- You can substitute the vegetable oil with melted coconut oil or another neutral oil if preferred.
- To keep muffins moist longer, store them in an airtight container at room temperature for up to 3 days, or refrigerate for up to a week.
- For a gluten-free version, substitute all-purpose flour with a gluten-free flour blend and ensure oats are certified gluten-free.
- Adding nuts is optional but highly recommended for added texture and flavor.
