Why this Recipe Works

With so many zucchini recipes on this site, you’d think I would have had enough. Not true.

I’m always looking for more ideas for ways to bake with zucchini! The shredded vegetable adds so much moisture to breads, cakes, and muffins.

  • These Zucchini Banana Bars are based on my Cinnamon Frosted Zucchini Bars.
  • Cinnamon glaze topping adds a layer of perfect sweetness and a pretty finish.
  • This recipe is a delicious way to use up overripe bananas and extra zucchini!

Today’s recipe combines my love for Zucchini Banana Bread with my love for easy-to-share dessert bars! Still have leftover zucchini? You’ve got to try our zucchini cookies!

Ingredient Notes

Ingredients needed to make zucchini banana bars.
  • Shredded Zucchini. It’s up to you whether or not you peel the zucchini first. I’ve made this recipe both ways! Use our guide on how to shred zucchini for best tips and tricks.
  • Bananas. The riper (without being rotten) the better! Bananas with brown spots are perfect. If your bananas are yellow like mine above, use our tips on how to ripen bananas in minutes!
  • Vanilla. Use a pure vanilla extract for best flavor. I love the taste of my homemade vanilla extract here.

Easy Instructions

Beat in the dry ingredients, then fold in shredded zucchini.

Pour the batter into a greased baking pan. Bake for 25 to 30 minutes, then let cool completely.

Whisk together the ingredients for the cinnamon glaze. Pour over the cooled bars.

Slice into squares and enjoy!

Tips and Tricks

  • How to shred zucchini. Place the bottom of a box grater into a large bowl. Press the zucchini into the grater and pull downward creating long shreds.
  • Food processor option. A food processor with a grating attachment can also be used to shred zucchini. Just be careful not to over process or you’ll end up with zucchini puree!
  • Storing zucchini. Use shredded zucchini right away or transfer to a freezer bag to store in the freezer for later use.

Recipe FAQs

Can you use frozen shredded zucchini in this recipe?

Yes, frozen zucchini can be used. Thaw it first and squeeze out any excess water with a paper towel.

Do you need to squeeze the water out of fresh zucchini first?

If your zucchini looks very watery after shredding, it’s a good idea to squeeze it with a paper towel over the sink to remove some of the extra liquid. Otherwise, I just add it straight to the batter.

How do you store these bars? Do they need to be chilled?

No chilling is required in this recipe. Store a pan of bars loosely covered in plastic wrap. It’ll keep well at room temperature for about three days.

Do you mash the banana separately?

That depends on how you mix the batter. I use an electric stand mixer with the paddle attachment. It’s plenty strong enough to mash the banana as it mixes it into the batter. If you’re mixing the batter by hand, I’d mash the banana in a separate bowl with a fork or potato masher first.

    1. Yay for more zucchini! It means I can eat as many of these bars as I want and get plenty of vegetables, right? 😉

    3. I’ve been making all things zucchini too lately! Love the addition of banana in here. Pinned!

    4. Oh my goodness, the glaze on top is calling my name! Banana and zucchini together sound amazing, like combining two delicious sweet breads…

    5. These look amazing! I need to buy zucchini stat! Do you think whole wheat flour would change the recipe much?

      1. It definitely would change it. Maybe try only subbing half of the flour for whole wheat?

    6. I’m lovin’ all these zucchini recipes! Pairing zucchini with the banana sounds like a fantastic combination!

    7. these zucchini bars look so delicious and SO moist.. definitely craving one right now!

      These are great! So thick and tempting!

    9. I haven’t made the zucchini-banana combination yet, and I really need to — I know I’d love it! These bars look incredible, and i’m thinking I’d totally be eating them for breakfast. 🙂

    10. I made banana zucchini muffins a week or so ago and I am loving the looks of these bars! Dense, moist, soft, and with a glaze! My perfect kind of bar! Love baking with both banana + zucchini! Pinned 🙂

    11. I have seen so many zucchini and banana breads, but never in bars! That sounds incredible! The warm spices combined with the summer veggie is surprisingly addictive. Pinning these!

    12. Who knew such a boring veggie could transform into such magical treats — love these 🙂

      1. They are indeed magical treats…and healthy too right? Fruit and veggie bars is what I should have called them! Ha!

    13. I totally do that at farmer’s markets too! And then it all goes bad before I can use it. I’m so sad we don’t have zucchini plants this year. These look SO good!

      1. We usually end up having a giant salad day! With all the excess veggies that weren’t eaten! Thanks for stopping by 🙂

    14. I love baking with Zucchini. They’re so moist and you feel less guilty eating lots of cake and slice!
