Why Choose This Zucchini Oatmeal Muffins Recipe
This Zucchini Oatmeal Muffins Recipe uses simple pantry ingredients, plenty of oats, and a full cup of shredded zucchini for moisture and fiber. The muffins taste like a cross between zucchini bread and oatmeal cookies, with warm spices and a soft, hearty texture.
You mix everything in two bowls, no mixer needed, and the batter comes together in about 10 minutes. The muffins freeze well, travel well, and stay tender without a ton of oil or butter.

Ingredients You’ll Need
Dry ingredients
- 1 cup old-fashioned rolled oats
- Use regular rolled oats, not instant or steel-cut, for the best texture.
- 1 cup all-purpose flour
- You can swap up to half with white whole wheat flour for a heartier muffin.
- 1 teaspoon baking powder
- 1/2 teaspoon baking soda
- 1 teaspoon ground cinnamon
- 1/4 teaspoon ground nutmeg
- 1/2 teaspoon fine sea salt
Wet ingredients
- 1 large egg, room temperature
- 1/3 cup neutral oil (canola, avocado, or light olive oil)
- You can use melted coconut oil, but cool it slightly so it does not cook the egg.
- 1/3 cup plain Greek yogurt or sour cream
- I like full-fat or 2% for extra tenderness.
- 1/3 cup milk (dairy or unsweetened almond milk both work)
- 1/2 cup light brown sugar, packed
- Coconut sugar works as a less refined option, though it tastes slightly deeper and less sweet.
- 1 teaspoon vanilla extract
Zucchini and mix-ins
- 1 cup finely shredded zucchini, lightly packed
- No need to peel; the skin adds color and nutrition.
- 1/3 cup mini chocolate chips or chopped dark chocolate
- I like Ghirardelli or Guittard for consistent melt and flavor.
- 1/4 cup chopped walnuts or pecans (optional)
- 2 tablespoons raisins or dried cranberries (optional)
Equipment
- 12-cup muffin pan
- Paper liners or nonstick spray
- Two medium mixing bowls
- Whisk and rubber spatula
- Box grater for the zucchini
- Measuring cups and spoons
- Cooling rack
Tips & Tricks
- Squeeze the shredded zucchini gently in a clean kitchen towel if it feels very wet, so the muffins do not turn soggy.
- Stir the batter until everything just combines, and stop; overmixing makes tough muffins.
- Use room temperature egg and yogurt so the batter mixes smoothly and the muffins rise evenly.
- Fill muffin cups about 3/4 full for nicely domed tops without overflow.
- Sprinkle a few extra oats or chocolate chips on top of each muffin before baking for a bakery-style look.
- Let the muffins cool in the pan for 5 minutes, then move them to a rack so they do not steam and turn dense.
- Bake one test muffin if you use a new oven or pan, and adjust time by a minute or two as needed.
- Use silicone muffin liners if you bake often; they release cleanly and save on paper liners.
How to Make Zucchini Oatmeal Muffins Recipe
Step 1: Prep the pan and oven
Preheat your oven to 375°F (190°C). Line a 12-cup muffin pan with paper liners or grease each cup lightly with oil or nonstick spray. Set the pan aside while you mix the batter.
Step 2: Shred and prep the zucchini
Wash and dry the zucchini. Grate it on the small or medium holes of a box grater. If the zucchini releases a lot of liquid, squeeze it gently over the sink or in a clean towel, then measure 1 cup of the lightly packed shreds.
Step 3: Mix the dry ingredients
In a medium bowl, add the rolled oats, flour, baking powder, baking soda, cinnamon, nutmeg, and salt. Whisk everything together until the mixture looks uniform and the spices distribute evenly. This step helps the muffins rise evenly and keeps you from overmixing later.
Step 4: Mix the wet ingredients
In another medium bowl, whisk the egg until it looks slightly frothy. Add the oil, Greek yogurt, milk, brown sugar, and vanilla extract. Whisk until the mixture looks smooth and the sugar starts to dissolve.
Step 5: Combine wet and dry
Pour the dry ingredients into the bowl with the wet ingredients. Use a rubber spatula to fold the mixture together, scraping the sides and bottom of the bowl. Stop as soon as you no longer see big streaks of dry flour; a few small lumps count as normal.
Step 6: Fold in zucchini and mix-ins
Add the shredded zucchini to the batter and fold it in gently. Stir in the chocolate chips, nuts, and dried fruit if you use them. Make sure the add-ins spread evenly so each muffin gets a good mix of texture and flavor.
Step 7: Fill the muffin pan
Use a scoop or large spoon to divide the batter among the 12 muffin cups. Aim to fill each cup about 3/4 full. If you want pretty tops, sprinkle a pinch of oats or a few extra chocolate chips over each portion of batter.
Step 8: Bake the muffins
Place the muffin pan on the middle rack of the oven. Bake for 15 to 18 minutes, until the tops look golden and a toothpick inserted in the center of a muffin comes out clean or with a few moist crumbs. If your oven runs hot, start checking at 14 minutes.
Step 9: Cool and serve
Remove the pan from the oven and set it on a cooling rack. Let the muffins sit in the pan for about 5 minutes so they set up and release more easily. Move the muffins to the rack and cool them to room temperature, then enjoy or pack them up for later.
What to Serve with Zucchini Oatmeal Muffins Recipe
Serve these Zucchini Oatmeal Muffins warm with a smear of peanut butter, almond butter, or a little softened butter for extra richness.
