What Makes It So Special

This zucchini bread with cinnamon swirl is hands-down delicious.

I added a luscious cinnamon swirl right through the middle, plus a crumbly topping that makes it feel extra indulgent—like a cozy lemon zucchini coffee cake disguised as zucchini bread. The different layers of sweetness and spice balance out perfectly for a mouthwatering treat that’s anything but boring.

Here’s why you’ll want to make it again and again:

• Great for breakfast or dessert. It looks beautiful when you slice into it and drizzle the glaze on top, so it’s fantastic for brunch tables, morning coffee, or even an after-dinner sweet.
• No-fuss and fast. Because it doesn’t require a stand mixer or a ton of steps, you can throw this together pretty quickly. Plus, it uses ingredients you probably already have in your pantry and fridge!
• Double the goodness. You end up with two loaves, so one is for now and the other can be tucked away in the freezer to enjoy later.

Ingredients for the Loaf

• 4 cups all-purpose flour
• 1 ½ cups granulated sugar
• 2 teaspoons baking powder
• 1 teaspoon baking soda
• 1 teaspoon salt
• 2 cups shredded zucchini
• ⅔ cup unsalted butter melted
• 1 Tablespoon cinnamon
• ½ cup milk
• 4 large eggs
• 1 cup all-purpose flour
• 1 cup light brown sugar packed
• 1 cup unsalted butter melted
• 1 Tablespoon cinnamon
• 1 cup powdered sugar
• 2 Tablespoons milk
• 1 teaspoon cinnamon

Putting the Loaf Together

1. Preheat oven to 350°F and line the bottoms of two 9-inch loaf pans with parchment paper or spray them with cooking spray.
2. Lightly beat the eggs.
3. In a large bowl, stir together all the bread ingredients (flour, sugar, baking powder, baking soda, salt, cinnamon, shredded zucchini, melted butter, milk, and eggs) until just combined.
4. In a smaller bowl, mix the cinnamon swirl ingredients (flour, light brown sugar, melted butter, and cinnamon) until blended and crumbly.

5. Pour half the batter evenly into the prepared pans, sprinkle half the cinnamon swirl over the batter, add the remaining batter, then top with the remaining cinnamon swirl.

   

6. Bake at 350°F for about 60 minutes or until a toothpick inserted into the center comes out clean.
7. Let the loaves cool in the pans for 10 minutes, then transfer to a wire rack to cool completely.
8. Whisk together powdered sugar, milk, and cinnamon until smooth and pourable, then drizzle the glaze over the cooled loaves.

Pro Tips and Troubleshooting

• No need to peel your zucchini. The skin softens in the bake and gives a nice bit of color and nutrition. It’s perfect just grated as-is — unless you’re trying to sneak it past picky eaters!
• Lightly beat your eggs. Taking a quick moment to whisk your eggs before adding them helps create a lighter, fluffier bread texture.
• Check for doneness with a toothpick. Stick a toothpick or small knife into the center of the loaf — when it comes out clean, you’re done baking!
• Cool fully before glazing. Give the loaves a chance to cool mostly before adding the glaze, or it will melt right in. Patience here will give you that pretty drizzle on top.

This zucchini bread with cinnamon swirl pairs so well with coffee, it’s almost made for it.

Flavor Twists and Substitutions

Feel like switching things up? These simple tweaks and additions keep the basics easy but add new flavors and textures:

• Fat swaps: Use melted vegetable or coconut oil instead of butter for a subtle flavor change and a slightly different texture.
• Extras: Mix in about a cup of chopped nuts (walnuts or pecans), chocolate chips, or dried fruit like cranberries or raisins to add fun bites throughout.
• Flour options: Substitute up to half of the all-purpose flour with whole wheat pastry flour to get nuttier flavor and a cozier crumb. For gluten-free, pick a 1:1 blend made for baking.
• Flavor twists: Add a pinch of nutmeg or cardamom to the batter, or stir in a little vanilla extract into the batter or glaze. A zest of orange or lemon brightens the glaze beautifully too. For more citrus inspiration, see Pioneer Woman’s Zesty Lemon Zucchini Bread Recipe.
• Texture changes: Leave off the glaze and add extra cinnamon swirl to make it more like a coffee cake. Or, bake the batter in muffin tins at 350°F for 20–25 minutes for portable treats (or try Chocolate Peanut Butter Zucchini Bread or Muffins for a chocolatey muffin variation).
• Topping swap: Use a cream cheese frosting instead of glaze, or sprinkle on a streusel made with flour, brown sugar, cinnamon, and cold butter before baking for extra crumbly goodness.

Storing, Freezing, and Reheating

Here’s how to keep your zucchini bread with cinnamon swirl fresh and ready when you want it:

• Room temperature: Once completely cooled, wrap the bread tightly in plastic wrap or foil, or store it in an airtight container. It will stay fresh for up to 5 days.
• Fridge: You can refrigerate glazed or sliced bread in an airtight container for up to a week, but note it might dry out quicker. Warm slices a bit before serving to get that fresh-baked feeling back.
• Freezing: Wrap full loaves or individual slices tightly in foil, then pop them in an airtight freezer bag. Freeze for up to 3 months. Thaw overnight in the fridge or at room temperature for a few hours before unwrapping and reheating.
• Reheating: Zap single slices in the microwave for 10 to 20 seconds. For a crispier crust, warm slices or wrapped portions in a 300–325°F oven for 5 to 10 minutes. Whole loaves heat well wrapped at 300°F for 10 to 20 minutes. This same oven method also revives the sugary crust on Cinnamon Sugar Donut Sweet Bread.
• Make-ahead: You can mix up the cinnamon swirl or glaze a week ahead and keep them refrigerated. Bake and freeze the bread to enjoy later, or bake the day before—just keep it wrapped at room temp until serving.

Answers to Common Questions

Do I need to squeeze the liquid out of the zucchini before using it?

Nope! You can toss the shredded zucchini in just as it is. For recipes that do benefit from draining, like zucchini corn fritters, squeezing helps them crisp. That extra moisture keeps the bread wonderfully soft and tender.

How should I store this bread at room temperature?

Wrap the fully cooled bread in foil or plastic wrap and keep it on the counter. It will stay fresh and tasty for up to five days this way.

What’s the best way to freeze Cinnamon Swirl Zucchini Bread?

After the bread cools completely, wrap it tightly in foil, then pop it into an airtight freezer bag. Freeze for up to three months. To thaw, move it to the fridge the day before, keeping it wrapped. It’ll thaw gently and keep its moisture.

Do I have to use the glaze?

The glaze is optional! If you prefer just the cinnamon crumble topping, that’s totally fine. But a drizzle of the glaze adds a pretty shine and a little extra cinnamon-sugar yum.
