When I make or eat muffins, the talking muffin joke always comes to mind. I still don’t really get it, but it’s a classic at this point. Two muffins were sitting in an oven. One turned to the other and said: “Hey, it’s pretty hot in here, isn’t it?” The other turned and shouted, “Oh my gosh a talking muffin!” Anyway, these Chocolate Zucchini Muffins are no joke. No one will believe that they are made with zucchini, but that is actually the secret to the moistness! For those doubters who could never fathom putting zucchini in a dessert, this will change their minds!

Chocolate Zucchini Muffins Recipe

This Chocolate Zucchini Muffins Recipe is taken from my Zucchini Brownies recipe but in a muffin form. Since muffins are more accepted as a breakfast food than brownies, it would be completely justified to have one of these muffins for breakfast! They are simple to make, and again, the zucchini does most of the work here!

Ingredients:

  • Vegetable oil
  • Sugar
  • Vanilla 
  • Flour
  • Cocoa powder
  • Baking soda
  • Baking powder
  • Salt
  • Zucchini, NOT drained
  • Chocolate chunks

You will notice that there are no eggs or butter added to this recipe. They are absolutely not needed! These Chocolate Zucchini Muffins bake up beautifully and do not need the added air and flavor that eggs usually add. This is a great recipe for vegan friends!

The Secret to Baking with Zucchini

Size matters. A large zucchini will be drier. A small zucchini with have more moisture. Certain recipes work best with different sizes. For instance, I tend to use a medium to small with this recipe because I want the moisture the zucchini brings, but I use a large zucchini for my Double Chocolate Zucchini Cupcakes.

Use the fine side of your grater. Coarser pieces will have a slightly more noticeable flavor and texture in a finished cake or bread recipe. (Farm kids tend to want that!)

Some recipes ask that the zucchini is pressed well with a clean towel to soak up excess moisture or to prevent whatever your baking from getting too soggy. Pay close attention to the recipe that you are making with zucchini as the level of moisture they provide is important. For instance, in this Chocolate Zucchini Muffins recipe, the zucchini is the main source of moisture and should NOT be drained! 

Can I Use Frozen Zucchini?

Yes, you can! First, bring the frozen zucchini to room temperature. Since frozen zucchini collects extra moisture, you WILL have to drain it before adding it to the recipe. If your batter looks too thick, you may need to add a little extra oil in the mix, starting with a teaspoon at a time.

How to Make Chocolate Zucchini Muffins

After you preheat the oven to 350°F, prepare two muffin pans with muffin liners. This recipe will make between 14-22 muffins, depending on how full you fill the liners. If you want an extra-large muffin, check out my Banana Zucchini Muffins! Next, it’s all about mixing together the ingredients to make your Chocolate Zucchini Muffins.

I added semi-sweet chocolate chunks to this batch to make the double chocolate. You can add milk chocolate chips, peanut butter chips, white chocolate chips, or no chips! They are so good and so rich the extra flavor is not necessary. (But can be fun!) If you do use chocolate morsels instead of chunks, be sure to use 1 1/2 cups instead of 1 1/4. Reserve a few for the top too!

  3. I can’t have regular flour & my friends & family are all on keto. What can we use instead? We do not use Regular sugar either. W me use stevia or xitilol or other. Help! I have lots of zucchini in garden! We use healthy almond or coconut flour

  4. After being totally surprised by adding one more tablespoon of oil and waiting for the moisture from the zucchini, these turned out super moist and tasty!!

  5. I love that you don’t have to squeeze the liquid out of the zucchini. That is not a task I enjoy. And the fact that my very picky child likes these is a huge bonus. They came together quickly and are delicious! Thank you!

  6. This recipe looks amazing. I was wondering if there is a way to cut the sugar down? Maybe even subs some of the oil for applesauce? I don’t want to ruin these because they look AMAZING!

  7. Oh my gosh, so so good! Make sure to sprinkle mini chocolate chips on top of each one and to eat them cold, and not hot! Really really delicous! 👍🏻

  8. You know those perfect little chocolate lava cakes you get for dessert when you go out to eat? THIS recipe is the perfect replica when it’s warm! Either right out of the oven, or warmed up in the microwave for 10 seconds, they’re perfect. A really moist bite of chocolate heaven that isn’t overly rich or overly sweet. Will be made in my kitchen often!
