Chocolate Zucchini + Carrot Muffins

April 7, 2019

A Chocolatey delicious way to use up those left over zucchinis! These Chocolate Zucchini and Carrot Muffins will be a new family favorite! 

I am a huge Costco shopper.  I’m also one of those Costco shoppers who tries to make a meal out of all the samples they give out during your shopping excursion.  Are you?  I’m not so aggressive that I knock over the other people waiting in line and grab three (even though the limit should be one), but I definitely take advantage of those little bites.

On my last Costco trip they were sampling the most incredible chocolate zucchini and carrot muffins, and I couldn’t believe how good they were! I knew immediately that I wanted to recreate them when I got home.

These chocolate zucchini and carrot muffins are loaded with chocolate chips and packed with all the great nutrients of carrots and zucchini! What’s even better, the shredded veggies makes these them so moist and incredibly delicious! They bake up perfectly and are the best way to use up zucchini from your garden.  For these chocolate zucchini carrot muffins, we’ll be using the muffins mixing method, so get your mixing bowls ready!

What is the muffin mixing method?

The muffin mixing method calls for you sift your dry ingredients  together (spices, flour, salt sugar, baking soda, and powder) in a large bowl.  Sifting helps to  break up any lumps in the flour and incorporates more air into it at the same time, which results in a much lighter flour.  It is easier to mix into other ingredients when making dough.  Some say it is the secret to creating light and fluffy cakes or cookies.

The wet ingredients are combined in a separate bowl, and then the two mixtures are combined together.  By mixing until JUST combined, you’re limiting the amount of gluten production during the mixing process, keeping quick breads light and tender.

Do I need to peel the zucchini before grating it?

I love to keep the skin on! It gives the muffins a great texture! For larger zucchinis, you can slice it in half length-wise and scoop out the seeds. Then slice off one end, and grate the flat end of the zucchini using a medium sized boxed grater. Continue until you reach the stem.  If you want to make things move a little faster, use can a food processor with the fine shredding disc attachment and feed the zucchini through the top of the food processor.

How long do chocolate zucchini carrot muffins last?

When freshly baked chocolate zucchini carrot muffins are properly stored, they will last for about 1 to 2 days at normal room temperature. If you keep them in the fridge, they’ll keep well for about 1 week in the fridge when sealed in an air tight container.  Make sure the muffins are completely cooled before placing in a ziplock bag or Tupperware container.

    Hi Dinner Fairy! Absolutely love the styling of this photo. You could literally make a stick look delicious! Steph is seriously going to make the muffins because apparently when you add veg to chocolate…. it cancels each other out! Have a good day 🙂

    Would this recipe work with swerve in place of suger? And have you ever tryed with non what flours?

    • Reply Nicole Triebe August 28, 2021 at 3:54 pm

      I’ve never used swerve but according to the reviews you can replace it cup for cup and it should be fine. I don’t recommend using alternative flours like almond, etc but Cup 4 Cup Gluten Free flour would work as a substitution.
