You’ve got to try Grandma’s moist zucchini bread made with sour cream—our family has baked this for years, and today we’re sharing her secrets. It’s delicious as a loaf, baked into muffins, or even adapted for an air fryer.
What’s the trick to making a truly moist zucchini bread? A few simple techniques make all the difference. This is our grandma’s tried-and-true family recipe—perfect as written, though you can easily customize it with add-ins like nuts, chocolate chips, or pineapple if you prefer.
We’ve been baking sweet quick breads for years and often give loaves away at the holidays. People always ask for the recipe. The key to excellent zucchini bread is using the right-sized zucchini, removing excess moisture, and carefully following the mixing and baking steps to preserve texture and moisture.
We keep this loaf simple—no frosting or crumble—so the tender crumb and gentle sweetness can shine. If you grow zucchini, this recipe is a wonderful way to use a bountiful harvest. It freezes well too: bake one now and freeze another for later.
Over the years we tested small tweaks—nuts, mini chocolate chips, pineapple—and each yields a tasty variation. Our favorite is still the classic version below with the moist, tender crumb everyone raves about.
How to Make the Best Zucchini Bread
Follow these essential tips for the best texture and flavor:
- Use medium zucchini: Medium-sized zucchini shred well without becoming overly watery. Large zucchini can yield a mushy result.
- Remove excess moisture: After shredding, place the zucchini between folded paper towels and press to remove water. It can be slightly damp but should not be dripping.
- Mix properly: Combine dry ingredients separately and beat wet ingredients separately. Add the dry mixture to the wet in portions until smooth. Fold in the drained zucchini gently at the end so it doesn’t break down the batter.
- Preheat the oven: Bake on the middle rack for an even temperature and to prevent the top from browning before the center is done.
Moist Zucchini Bread Ingredients
- 2 cups shredded zucchini (medium size), moisture pressed out
- 3 cups all-purpose flour
- 1 tsp baking powder
- 1 tsp baking soda
- 3 large eggs
- 1 tbsp cinnamon
- 3 tbsp brown sugar
- 2 cups granulated sugar
- 1 cup sour cream (or substitute vegetable oil)
- 1 tsp almond extract (optional)
- 3 tsp vanilla extract
Notes: Brown sugar adds a deeper, slightly molasses flavor and extra chewiness. Room-temperature eggs and fresh leavening agents help create a light, tender crumb. Mini chocolate chips (up to 1/2 cup) or chopped walnuts can be folded in for variation.
Baking Time
If baking two 9×5 loaves, bake at 325°F for about 50 minutes. The toothpick inserted into the center should come out with moist crumbs, not raw batter. Avoid overbaking to keep the bread tender and moist.
Muffins
To make muffins, divide the batter into a lined muffin tin and bake 18–22 minutes at the same temperature, or until they spring back when gently touched in the center.
How to Test for Doneness
Start checking at 50 minutes for loaves. Insert a toothpick into the center: if it comes out clean or with a few moist crumbs, the bread is done. If there’s wet batter on the toothpick, bake a bit longer and check again.
This recipe makes two loaves or one loaf plus about a dozen muffins. Let loaves cool enough to remove from the pans so they don’t keep cooking, then cool on a rack before slicing. For a finishing touch, drizzle a thin vanilla glaze over slices when serving.
If you want to make fewer loaves, halve the recipe and adjust baking time accordingly.
Moist Zucchini Bread Recipe
Equipment
- 2 9×5 loaf pans
- 2 bowls
Ingredients
- 2 cup zucchini, grated, moisture removed
- 3 cup all purpose flour
- 1 tsp baking powder
- 1 tsp baking soda
- 3 large eggs
- 1 tbsp cinnamon
- 3 tbsp brown sugar
- 2 cup sugar
- 1 cup sour cream (or vegetable oil)
- 1 tsp almond extract (optional)
- 3 tsp vanilla
Instructions
- Preheat oven to 325°F. In one bowl, whisk together all dry ingredients.
- In another bowl, combine all wet ingredients except the zucchini and beat on low until smooth.
- Add the dry ingredients to the wet in thirds, mixing until just combined. Shred zucchini onto folded paper towels, press to remove excess moisture, then gently fold the zucchini into the batter.
- Spray two loaf pans with nonstick spray or line with parchment. Divide batter between pans and bake about 50 minutes, or until a toothpick comes out with moist crumbs and the center springs back when touched. Do not overbake.
- For muffins, bake 18–22 minutes or until they spring back in the center. Allow loaves to cool slightly before removing from pans so they won’t overcook.
- Optional: drizzle a light vanilla glaze over slices when serving.

How to Store Zucchini Bread in the Freezer
To freeze, double-wrap the cooled loaf tightly in plastic wrap, then in foil. Properly wrapped, it will keep for two to three months. When thawing, remove the foil but leave the plastic wrap on until fully thawed; reheat briefly if desired.
Try other quick-bread variations once you master this method—pumpkin, banana, or zucchini-pineapple are all great options. This same approach works well whether you’re baking loaves or muffins.
