Why this Bread Works 

This is a seriously scrumptious zucchini bread recipe.

I added a ribbon of cinnamon filling inside and a crumbly topping to make this bread taste extra decadent. The extra sweetness, flavor, and texture work really well together.

Here are a few more reasons why you’ll love it,

  • Perfect for brunch or dessert. It looks lovely once it’s glazed and sliced, making it the perfect choice for breakfast, brunch, or dessert. 
  • Quick and simple. Since it doesn’t require a stand mixer or electric beaters, it’s a breeze to mix by hand. The simple ingredient list makes it easy to whip up last-minute, especially if you have a ton of zucchini from your garden! 
  • Enough for now and later. This recipe makes two loaves, so you can eat one now and freeze one for later if you like– or freeze both!

Ingredient Notes 

Ingredients needed to make cinnamon swirl zucchini bread.
  • Zucchini – Grated zucchini adds moisture, healthy fiber, and a little color to this sweet bread. Use our guide on how to shred zucchini.
  • All-Purpose Flour – Provides the basic structure for the bread, giving it a light but sturdy texture. 
  • Granulated Sugar – Sweetens the bread and helps it stay hydrated after baking.  
  • Cinnamon – Adds a warm spiced flavor to the bread, cinnamon swirl, and sweet glaze. 
  • Unsalted Butter – Melted butter makes this bread easy to mix and adds tons of rich flavor. If you use salted butter, be sure to cut the amount of salt in the recipe in half. 
  • Milk – Adds moisture and richness to the bread.
  • Eggs – Binds the ingredients together and adds richness and moisture. 
  • Baking Powder & Baking Soda – Both help the dough rise for a lighter crumb. Avoid substituting one for the other!
  • Salt – Balances the sweetness and enhances all the flavors. 
  • Light Brown Sugar – Adds flavor, sweetness, and soft texture to the cinnamon swirl.
  • Powdered Sugar – Creates the base for a quick, pourable cinnamon glaze. 

Easy Instructions

  1. Mix the batter. In a large bowl, mix all the bread ingredients together and stir until combined. 
  2. Mix the swirl. In a small bowl, blend the cinnamon swirl ingredients together. Set aside.
  3. Combine. Pour the batter evenly into the prepared pans. Sprinkle with half the cinnamon swirl, then top with the remaining batter. Finish with the remaining cinnamon swirl mixture.
  4. Bake. Bake for 60 minutes at 350°F. Cool for 10 minutes in the pan, then remove from the pan to cool completely.

Tips and Tricks

  • Don’t worry about peeling the zucchini. There’s no need to peel it unless you’re trying to hide the green color from wary children! 
  • Add beaten eggs to improve the texture. Lighten up the bread’s texture a little by beating the eggs lightly with a whisk before adding them to the bread dough mixture. 
  • Test for doneness with a toothpick. Make sure the cake is baked all the way through by inserting a toothpick or paring knife into the center. It should come out clean. 
  • Let the bread cool before glazing it. Try to be patient and wait until the cake has mostly cooled to drizzle the glaze over the top. If it’s too warm, the glaze can melt into the cake.

Serving Suggestions

Cinnamon Swirl Zucchini Bread was almost made to go along with a coffee drink. Try your morning cup with some of my Homemade Cinnamon Coffee Creamer for a delightful pair. Or for a coffee shop-type treat, try it with a glass of foamy Dalgona Coffee.

As I mentioned before, this sweet bread is also a top-notch choice for a brunch spread. Pre-slice it and lay it out on the table next to a classic Ham & Cheese Quiche or an easy Breakfast Casserole and dig in! 

Recipe FAQs 

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

Nope! You can add the shredded zucchini as it is. This makes the bread taste exceptionally moist and soft. 

How should I store this bread at room temperature?

To store it at room temperature, wrap the cooled bread in foil or plastic wrap. Expect it to last up to 5 days. 

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

To freeze it, first, wrap the fully-cooled bread in aluminum foil. Then slide it into an airtight freezer bag and freeze it for up to 3 months. To thaw it, take it out a day before and let it thaw in the refrigerator without removing the wrapping. 

Do I have to use the glaze?

The glaze can be left out if you only want the crumble on top. However, a generous drizzle of glaze does add visual appeal and extra flavor!

    This turned out good for me. Cut the recipe in half andI added vanilla. My oven runs hot so one hour is too long for baking it. It’s still good just a little too
