The Secret to Truly Moist Zucchini Muffins With Oats
The biggest mistake people make with zucchini oat muffins is skipping one crucial step: squeezing out the zucchini's excess moisture. Zucchini holds an enormous amount of water, and if you don't drain it, your batter turns soupy and your muffins bake up dense or gummy.
Here's the simple process:
- Shred the zucchini using the large holes of a box grater.
- Wrap it in a clean kitchen towel or a few layers of paper towel.
- Squeeze firmly over the sink until the liquid stops running.
Chef's Tip: Don't discard that zucchini liquid too quickly. If your batter ends up a touch too thick after mixing, a tablespoon or two of that reserved liquid can loosen it right up.
A Few Notes on Ingredients
This recipe leans on old-fashioned rolled oats rather than instant oats, since they hold their shape and add a pleasant chew that instant oats simply can't replicate. The combination of both baking soda and baking powder gives the muffins good lift while keeping the crumb tender.
For sweetness, brown sugar is doing double duty. It sweetens the batter and also contributes a soft, caramel-like moisture that keeps these healthy zucchini oatmeal muffins from ever tasting dry. Ground cinnamon is the backbone of the flavor here, turning these into more of a zucchini cinnamon oatmeal muffin than a plain veggie muffin, which is exactly what makes them so craveable.
Walnuts are optional but highly recommended if you like a bit of crunch against the soft, moist crumb. Pecans work beautifully too, or you can leave the muffins nut-free for lunchbox purposes.

Moist Zucchini Oatmeal Muffins
These moist zucchini oatmeal muffins are packed with hearty oats, warm cinnamon, and fresh shredded zucchini for a wholesome breakfast or snack you'll want to make on repeat.
Ingredients
- 1 cup old-fashioned rolled oats, plus extra for topping
- 1 cup all-purpose flour, spooned and leveled
- 2 tsp ground cinnamon
- 1 tsp baking soda
- 1/2 tsp baking powder
- 1/2 tsp salt
- 1 1/2 cups shredded zucchini, packed, excess moisture squeezed out
- 2 large eggs, room temperature
- 1/2 cup brown sugar, packed
- 3/8 cup vegetable oil, or melted coconut oil
- 1 tsp vanilla extract, pure
- 1/2 cup chopped walnuts, optional
Instruction
Preheat the oven to 350 degrees F (175 degrees C) and line a 12-cup muffin tin with paper liners or grease well.
In a large bowl, whisk together the rolled oats, flour, cinnamon, baking soda, baking powder, and salt.
In a separate bowl, whisk the eggs, brown sugar, oil, and vanilla extract until smooth and well combined.
Squeeze any excess water out of the shredded zucchini, then fold it into the wet ingredients.
Pour the wet mixture into the dry ingredients and stir gently just until combined, being careful not to overmix.
Fold in the chopped walnuts, if using, reserving a few for topping.
Divide the batter evenly among the muffin cups, filling each about three-quarters full.
Sprinkle the tops with a few extra oats and reserved walnuts for a rustic finish.
Bake for 20 to 22 minutes, or until a toothpick inserted into the center comes out clean.
Let the muffins cool in the pan for 5 minutes, then transfer to a wire rack to cool completely.
Equipment
- 12-cup muffin tin
- Paper liners

Serving Suggestions and Storage Tips
These muffins are fantastic warm out of the oven with a pat of butter melting into the top, but they're just as good at room temperature, which makes them ideal for meal prep or lunchboxes. Pair them with a cup of coffee or tea for a cozy breakfast, or slice one in half and add a smear of cream cheese for an afternoon treat.
To store, keep the muffins in an airtight container at room temperature for up to 3 days, or in the refrigerator for up to a week. For longer storage, these freeze exceptionally well:
- Let the muffins cool completely before freezing.
- Wrap individually in plastic wrap or freezer bags.
- Freeze for up to 3 months.
- Thaw at room temperature or microwave for 20 to 30 seconds.
Chef's Tip: If you're doubling the batch for a crowd, bake the extra muffins on the same day rather than storing raw batter. Zucchini batter loses its structure and rises less well if it sits too long before baking.
Variations to Try
Once you've mastered the base recipe, there's plenty of room to make it your own. Add a handful of mini chocolate chips for a slightly indulgent twist, swap the walnuts for pecans or sunflower seeds, or stir in a tablespoon of ground flaxseed for extra fiber. However you make them, this zucchini and oatmeal recipe is endlessly adaptable and always a hit.
