Why this Recipe Works

  • 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!

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.

Today’s recipe combines my love for Zucchini Banana Bread with my love for easy-to-share dessert bars!

Ingredient Notes

Shredded Zucchini. It’s up to you whether or not you peel the zucchini first. I’ve made this recipe both ways!

Bananas. The riper (without being rotten) the better! Bananas with a few brown spots are perfect.

Vanilla. Use a pure vanilla extract for best flavor. I love the taste of my homemade vanilla extract here.

Easy Instructions

Beat butter and sugar together. Mix in egg and vanilla. Add the bananas and mix with the electric mixer until mashed and combined.

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.

Comments & Reviews

  1. I really oughta start baking with zucchini more — all of these zucchini recipes you’ve been posting look so sinful and delicious! ESPECIALLY these banana bars — obsessing over the glaze!

  2. Love the sound of these! Do you think it would be possible to make these without adding the sugar, since the bananas would make them sweeter already? Or would that change the texture to much?

  3. We don’t have farmers’ markets here!!!!! *sobs* The only place where I have seen one is on TV when I watch TLC and it looks so vibrant and beautiful, I am a 173904% sure I’ll end up splurging on fresh produce as well! These zucchini bars look soooo DELISH!!!! And that glaze just makes my heart sing! Pinning! 😀

  4. A slice of both zucchini treats sounds perfect to me!! Love that cinnamon glaze on top!!! Yum!

  5. Ooh, freshly made empanadas! Where is this market again – I think I might be there next Saturday, too! That’s something I’d love to try making myself.
    As for these bars, I love your ideas as to how to use zucchini in baked things. I tried making some healthy zucchini muffins a week or two ago and they were just about the worst thing I’d ever made. I think the banana in these would work a treat!

  6. I’ve made zucchini bread and a zucchini cake, but I’ve never thought to combine them with bananas. Love this!
