Folks, I feel like we’ve FINALLY made it to summer in Ohio. And get this, we’ve had about 5 days straight without rain!

We took advantage of the gorgeous weather this weekend and set Elle and her friend up with a lemonade and cupcake stand.

I mean, who can refuse a couple of cute kiddos selling adorably packaged chocolate cupcakes with delicious buttercream frosting and lemonade? Clearly, no one because the girls sold out in less than 2 hours.

She earned $20 and I’m pretty sure we’ve ignited her entrepreneurial spirit because we’re already prepping for her next dessert sale! We’re thinking mini cheesecakes and my favorite chocolate chip cookies along with these chocolate zucchini muffins.

TIPS FOR BAKING WITH ZUCCHINI

As soon as the weather warms up, I get way into zucchini. From Lemon Zucchini Cake to Zucchini Cookies, I fully believe zucchini belongs in allllllll the baked goods.

Don’t believe me? Take a look at these 10 Zucchini Desserts and I bet you’ll change your mind.

Zucchini is perfect for adding to baked goods because the delicate flavor allows it to blend in perfectly with sweet cake or bread batters. It also keeps baked goods moist without having to add a lot of extra oil or fat to the recipe.

Everyone has come across a giant zucchini or two during the summer. You know what I’m talking about – zucchini that got left a bit too long on the vine and are a little too fibrous to enjoy on their own.

Those big zucchini are perfect for baking!

Whenever I bake with zucchini, whether it be in a cake or in zucchini muffins, I always grate it super fine because it practically disappears into the batter. Most of the time, you probably wouldn’t even know it’s there if you can’t see it!

My dad, who is not fond of the green squash, noshed down a couple of these Chocolate Zucchini Muffins in a matter minutes, and proclaimed them freaking delicious.

And I have to say, I totally agree with him.

THE BEST DOUBLE CHOCOLATE ZUCCHINI MUFFINS

So let’s talk about these Chocolate Zucchini Muffins. They’re honestly one of the best muffins that I’ve ever made. And that’s a tall order, given I run a baking website.

Chocolate Zucchini Muffins could easily be called “Double Chocolate Zucchini Muffins” because the chocolate batter is packed with chocolate chips.

You read that right! They are full of chocolate flavor from using cocoa powder and two types of chocolate chips, and the texture is simply amazing thanks to the zucchini.

They’re absolutely perfect for sneaking some veggies into a chocolate lover.

These Chocolate Zucchini Muffins will last about 3 days at room temperature in an airtight container. You can also freeze them for easy breakfasts later.

When you’re ready to eat one, just pop it in the microwave straight from the freezer for about 30 seconds to 1 minute for a warm muffin breakfast on the go.

I mean, who wouldn’t want a warm, chocolatey muffin for breakfast?

    Hey! I just tried chocolate zuchinni muffins at a friend’s house and they look absolutely delicious! I can’t wait to try this recipe! I just have a quick question. I’m not a large fan of chocolate since I find it somewhat overpowering. I was wondering if the chocolate chips that need to be folder into the batter are essential to the overall taste of the muffin? I like the chocolate flavour but feel as if too much of both chips and coco powder would be a little much and hdetest biting into a whole chocolate chip. Could I take those out without disrupting the flavour or would i have to balance it out with some additional cocoa powder?

    Thanks and have a great day!

    1. Jamie says:

      I think you could definitely leave out the chocolate chips if you want to. :)

    They are currently baking in the oven. But the batter seemed a bit thick to me. Is a thick batter consistency the norm?

    1. Jamie says:

      Erica-
      I hope they turned out great! They batter is definitely on the thicker side. Happy Holidays to you and yours!
      -Jamie

  6. Nicole says:

    Am I suppose to peel the zucchini before I shred it?  -Thanks, Nicole

    1. Jamie says:

      I don’t peel it. I just wash and dry them, then shred them up. Hope this helps!
      -Jamie

  7. ValerieW says:

    Made this recipe with all semi-sweet chocolate chips as that was all I had. Also substituted half the cooking oil for coconut oil. Absolutely delicious. The perfect ratio of ingredients for a chocolatey, moist muffin. 

    1. Jamie says:

      So glad to hear you enjoyed them, Valerie! I love the idea of the coconut oil. I need to try that next time. Happy baking!
      -Jamie

  8. Emma says:

    I made these yesterday. Everyone loved them & no-one detected the secret ingredient However when I make them again if use twice as much cocoa for my personal tastes.

    1. Emma says:

      Obvs I meant “I’d” use twice as much cocoa…. My phone loves to incorrectly auto correct.

    2. Jamie says:

      So glad to hear you enjoyed them, Emma!

  9. Gabe Kluka says:

    Great recipe! I’ve made these 1/2 doz times or so. They freeze well, so I make several batches at a time (I don’t double it though…). Thanks!

    1. Jamie says:

      So happy to hear you enjoyed them, Gabe. Thanks so much for stopping back and leaving your feedback!

    Absolutely delicious! I’m really happy I found this recipe. We baked them for a corporate event because we wanted to avoid buying the same old cupcakes again. They ended up coming out great and were a huge hit! We packed each of them individually in a clear cello wrap and bundled each gift with some other customized chocolate items. It was fun to bake them and even more fun to see the reactions. Thanks!

    1. Jamie says:

      Wonderful, Jeleisa! I’m so glad you had fun with the recipe.
