Moist, fluffy zucchini muffins with warm cinnamon spice and a light sugar topping. Made in one bowl with simple ingredients, these muffins are perfect for a quick breakfast, healthy snack, or make-ahead treat.
Preheat and Prepare the Pan: Begin by setting your oven to 375°F (190°C) so it’s fully heated when you’re ready to bake. While the oven warms up, line a standard 12-cup muffin tin with paper liners. If you don’t have liners, you can lightly grease each muffin cup with oil or nonstick spray. This step ensures that the muffins release easily after baking without sticking to the pan.
Combine the Wet Ingredients: In a large mixing bowl, add 1 cup granulated sugar and ½ cup vegetable oil (or canola oil). Using a whisk or a sturdy spoon, stir until the sugar dissolves slightly into the oil and forms a smooth mixture. Next, crack in two large eggs and whisk again until the mixture becomes pale, glossy, and slightly thickened. This blending step creates a strong base that will hold the muffins light and fluffy once baked.
Add the Zucchini and Vanilla: Take 1 cup of coarsely grated zucchini and fold it into the egg mixture. There’s no need to squeeze out the moisture from the zucchini—it’s the secret to keeping the muffins naturally soft and moist. Stir in 2 teaspoons of vanilla extract, which adds warmth and a subtle sweetness that enhances the overall flavor. Make sure the zucchini is evenly distributed so every bite gets the same tender texture.
Mix in the Leavening Agents and Salt: Sprinkle 1 teaspoon baking soda, ½ teaspoon baking powder, and ¾ teaspoon salt directly over the wet mixture. Instead of tossing them in all at once, scatter them evenly across the surface. This technique ensures they distribute well and won’t clump in one spot. Gently whisk until everything is just incorporated. The baking soda and baking powder will later react with the moisture and heat, creating light and airy muffins.
Incorporate the Dry Ingredients: Gradually add 1 ½ cups of all-purpose flour along with 1 teaspoon ground cinnamon into the bowl. Switch to a spatula or wooden spoon and fold the flour mixture into the wet batter slowly. Mix only until the flour is no longer visible—over-mixing at this stage can make the muffins dense instead of tender. The cinnamon provides a warm spice note that balances the sweetness of the sugar.
Fold in Optional Add-Ins: If you’d like a bit of crunch or extra flavor, gently fold in ½ cup chopped pecans or walnuts. Alternatively, you can swap the nuts for raisins or chocolate chips to suit your taste. Stir carefully so the add-ins are spread evenly without overworking the batter.
Fill the Muffin Cups: Using a spoon or an ice cream scoop, divide the batter evenly among the 12 muffin cups, filling each one about ¾ of the way full. This ensures they rise beautifully without overflowing. For a bakery-style finish, sprinkle a pinch of coarse sugar on top of each muffin. This creates a lightly crisp, golden crust once baked.
Bake Until Perfectly Golden: Place the muffin tin on the center rack of the preheated oven. Bake for 18–22 minutes, or until the tops are golden brown and a toothpick inserted into the center of a muffin comes out clean. Keep an eye on them in the final few minutes to avoid overbaking, as this can dry them out.
Cool Before Serving: Remove the muffin tin from the oven and allow the muffins to cool in the pan for 5 minutes. Then carefully transfer them to a wire cooling rack. Letting them cool slightly helps the muffins firm up while still staying moist inside. These muffins are delicious warm, but they also keep their flavor and texture once completely cooled.
Notes
No need to squeeze the grated zucchini; the natural moisture keeps the muffins soft and fluffy.
Don’t overmix the batter once the flour is added—this helps prevent dense muffins.
For a bakery-style finish, sprinkle coarse sugar on top before baking.
Customize the flavor by adding nuts, chocolate chips, or dried fruit.
Muffins taste even better the next day after flavors settle.
