Caramel Frosted Zucchini Pecan Bars

These zucchini bars with caramel frosting are the richest and most decadent in my arsenal of zucchini desserts ~ the cake is uber moist and the frosting is dense and delicious, almost like a caramel fudge!

the ultimate zucchini bars

I feel like I can move on now, confident that I’ve covered everything in the zucchini department, from pancakes and brownies to burgers, fries, crisps, casseroles, cakes, pies, and more. I’ve done well by these little green squash. But they deserve all the attention ~ they’re so easy to grow, and they’re always available. When you shred and bake them into bars like these, they add an indescribable lusciousness. If you still have zucchini left in your garden, or you just love the little guys, these bars will make you happy.

The frosting is omg delish

It’s an easy cook and pour deal that really makes these bars hard to resist. It’s thick and rich and turns simple zucchini bars into something unique and special. It’s actually hard to believe that milk, butter, and sugar can transform in a matter of minutes into this divine substance!

how to make hot caramel frosting

Once you see how easy it is to make this epic frosting, you’ll want to pour it over everything (I won’t stop you.)

  1. Combine butter, brown sugar, milk and salt in a small saucepan. Note: you can use half and half, heavy cream, or even buttermilk in place of the milk.
  2. Bring to a boil, stirring.
  3. Whisk in powdered sugar until smooth and glossy.
  4. Pour over your zucchini bars.
  5. Lick the pan clean.

the decadent side of zucchini!

This is about as decadent as zucchini will ever get, unless of course you consider my chocolate zucchini bread. The two of them bring out a side of this summer veg we don’t get to experience very often. I’m sure you’ve got plenty of zukes to spare right now, so why not take the plunge and give these a try? Believe me, they don’t disappoint!

    This look like #1 bars. I pinned it for the frosting. I didn’t have good success with Paula Deen’s caramel frosting. It just tasted sweet and not like the caramel frosting I actually got from a QFC bakery. Soooo I am pleased to find another tested recipe to try.

    I love every word in this recipe’s name! And I’m giggling that you told me I can’t pretend these are healthy because they have zucchini. I might still try though!
