Zucchini Bars

The best, folks. I got this zucchini bars recipe from my aunt and I have to tell you these are amazing. My aunt named this recipe literally "the best zucchini bars." I can't argue.

This is a healthy zucchini bars recipe, too. It has to be. It has zucchini AND carrots. I'm kidding! I know it's not healthy. The bar is cinnamony, moist, nutty, and heavenly. The cream cheese frosting I whipped together was the perfect complement to these bars. It's the same frosting I use on my cinnamon rolls. SO perfect.

You can see the bits and pieces of shredded zucchini and carrots in the zucchini bars. I think this is why my husband was hesitant to eat them. The man freaks out anytime a vegetable is involved in baking.

I tried to just say that they were spice bars, but that was a big FAIL. The bits of colorful veggies gave it away. So, I'm not sure how many pieces he ate of this, but myself, mom, and my uncle scarfed these zucchini bars with cream cheese frosting right down.

This zucchini bars recipe makes a huge pan of bars! You can serve a large family dessert with this recipe or eat a dozen yourself. Get yourself a large jelly roll pan.

If you don't have a jelly roll pan, I would recommend using two square pans but pay close attention that the bars aren't too thin. They bake up to be about an inch thick. They come to the top of the jelly roll pan when I bake them.

  1. These were delish! One question, my oatmeal seemed uncooked & a little "hard or chewy"(??), did I do something wrong? I used old fashioned oats. XX

    1. The next time I recommend using quick oats and it will have less of a chew to the oats in the bars.

  2. These zucchini bars are delicious!! I love the fact that there are carrots and oats in it! I used pecans and I also used about 3/4ths of the cube of butter and I used 1 3/4 cup of powdered sugar. I will make again. I didn’t have the right size pan but it still worked out. Thank you for sharing.5 stars

  3. My daughter made this recipe with our fresh garden Zucchini and it was absolutely delicious! We used more Zucchini and less carrots and the flavor was just right for us.. We will be making this again.5 stars

  4. I swapped the flour for the same amount of gluten free all purpose flour and it worked perfectly. These are incredible, I made them earlier this week and have already gotten requests to make them again!

    Will be a staple 🙂5 stars

  5. Very curious about a couple of things in your recipe, as this recipe sounds and looks delicious

    What do you mean by "Small" carrot? A little mini one?
    And what type of rolled oats? Quick oats or old-fashioned?

    1. By small carrot I mean a full sized carrot, about 6-8 inches long. Some carrots you find in the grocery store are massive and way too big- a full sized carrot on the smaller side works best.

      Old fashioned rolled oats are best!

    1. Yes you can freeze these! I recommend freezing the bars and adding the cream cheese frosting after thawing, before serving. The frosting part is best when made fresh!
