Zucchini Bars

Zucchini season is here and absolutely nothing tastes better than these moist and tender Zucchini Bars spiced with cinnamon and topped with a creamy, tangy, dairy free cream cheese frosting and handfuls of chopped walnuts. These bars and frosting make for an unforgettable combination and delicious treat.

Sweet breads such as zucchini bread are our family jam. The problem is they don't last more than a day around our home.

Is this the case for you, too?!

Needless to say we needed a recipe with the same classic cozy taste of zucchini bread, and way more of it!

So we're sharing our 9x13-inch baking pan Zucchini Bars recipe with you. It's not only a family favorite, but it's also the perfect size to enjoy because it lasts more than a day.

And this bread isn't just a family dessert recipe-- nope. Nada. Enjoy preparing this recipe for your next brunch or picnic, and it's perfect for special occasions such as baby showers and bridal luncheons too.

zucchini bar ingredients

Here's the ingredient list. You'll notice you most likely have the basic baking staples on hand already in your pantry. So grab fresh zucchini and let's bake.

  • eggs-- room temperature
  • brown sugar-- packed
  • vegetable oil-- we use grapeseed oil
  • vanilla extract
  • gluten free all-purpose flour-- we use Bob's Red Mill Gluten Free 1-1 Baking Flour; purchase it in bulk here to save money. This mix blend does contain xanthan gum. Use the spoon and level method when measuring.
  • xanthan gum-- omit if your all-purpose flour contains this or guar gum in the blend
  • baking soda-- this loses its potency after being opened for 6 months. We suggest labeling the container when opened.
  • kosher salt
  • ground cinnamon-- this adds a nice warm, cozy flavor and aromatic scent to the bars. Always double check spices are gluten and dairy free. The McCormick brand is known to be safe.
  • ground nutmeg
  • grated zucchini-- 2 medium zucchinis, washed, grated, lightly dried with paper towels, and lightly packed in the measuring cup
  • optional-- add in finely chopped walnuts or pecans to the zucchini batter

kitchen utensils

  • 9x13-inch baking pan with lid-- we've been using these Pyrex pans every week for years. You can use any kind of 9x13-inch pan; however bake times may vary. We poke a cake tester in the middle of the bars. Pull the tester up and if it's clean, the bars are baked through and can be removed. If there is zucchini batter on the cake tester, allow to bake longer.
  • electric stand mixer or handheld mixer
  • cheese grater-- this will give you perfectly grated zucchini
  • angled spatula-- you'll notice we use this spatula all.the.time. in our recipe posts. It's ideal for frosting anything in a pan because you can evenly coat the bars with frosting easily-- even in the corners.
  • serving spatula-- again this is a popular kitchen gadget in our home for easily serving dinner and dessert helpings

most asked questions

do you peel zucchini

Nope. Don't peel the zucchini even though it's tempting to remove the zucchini's skin, but there is no need. Zucchini melts into the bread, so peeling is just an unnecessary step. And the peel is nutritious.

how many zucchinis is two cups

You'll need 2 medium zucchinis for this recipe. Keep in mind leftover grated zucchini can be frozen.

how do I store fresh zucchini

Store zucchini in the fridge, keep the squash whole, dry and unwashed. Store in a plastic or paper bag with one end open to encourage air circulation. They'll keep there for 1 to 2 weeks, but eventually you'll see the skin start to shrivel over time.

can these bars be baked ahead of time

Yes. Actually for the best flavor bake these bars, top with the cream cheese frosting, cover, and refrigerate for 1-2 days ahead of time. The bars and cream cheese flavors taste best when they've had time to meld together.

The bars do need time to cool completely before frosting.

And plan on the cream cheese frosting needing at least 20 minutes to firm up in the refrigerator prior to icing.

do these bars need refrigerated

After the bars have cooled completely, cover with a lid and set on the countertop up to 2 days. After the bars have been frosted with cream cheese frosting, cover, and refrigerate until ready to serve. Keep any leftovers covered and refrigerate up to a week.
