Fudgy Double Chocolate Zucchini Muffins

These Chocolate Zucchini Muffins are moist and almost like a fudgy brownie. To make these double chocolate zucchini muffins fun for kids try adding M&Ms or baking bits to the batter and then place a few M&Ms on top of the freshly baked muffin while it is still warm.

Servings 12 muffins

Ingredients
  

  • 1 1/2 cups all purpose flour
  • 1 1/4 cups granulated sugar
  • 1/4 cup cocoa powder
  • 1 teaspoon baking powder
  • 1/4 teaspoon baking soda
  • 1/2 teaspoon salt
  • 1 cup grated, fresh zucchini undrained
  • 2 large eggs beaten *see note
  • 1/3-1/2 cup vegetable or canola oil
  • 3/4 cup chocolate chips, M&Ms or semi sweet baking bits

Instructions
 

Preheat oven to 350 degrees.

  • In a med-large mixing bowl combine flour, sugar, cocoa powder, baking soda, baking powder and salt. Add grated and undrained zucchini, eggs and 1/3 cup vegetable oil.
  • Mix the wet and dry ingredients until the batter is well combined. The batter should be somewhat thick because as the zucchini bakes and softens, it will also release moisture into the muffins.
  • Gently fold the chocolate of your choice into the zucchini muffin batter, being careful not to over mix the batter (overmixing muffins can cause them to be tough and to bake unevenly).
  • Fill lined muffin tins 2/3 full with the zucchini muffin batter and then bake the muffins in the preheated oven for 20-25 minutes until they have puffed up and a toothpick inserted in the center comes out clean.
  • Optional: Add M&Ms or baking bits onto the top of the warm muffins and then allow them to cool. As the muffins cool the baking bits will melt slightly and adhere onto the muffins.

Notes

If using smaller eggs, you may wish to add a little extra oil to the batter. Be sure to keep the batter from getting too wet before baking, because the zucchini will release its juices while baking as well. *see below for more notes and photos.

Some equipment needed for these chocolate zucchini muffins:

  • Mixing bowl I like to use my stainless steel mixing bowls for mixing up this chocolate zucchini muffin batter. My stainless steel mixing bowls are sturdy and dish washer friendly which is always a win for me!
  • Muffin tins Muffin tins are needed to bake the zucchini muffins in. I prefer to use non-stick muffin tins.
  • Cupcake wrappers Cupcake wrappers are optional, but I prefer to use them for easier removal of the muffins from the muffin tins and for less cleanup too.
  • Measuring cups Measuring cups are needed to get an accurate measurement of the ingredients listed in the recipe card.

Step 1: In a med-large mixing bowl combine flour, sugar, cocoa powder, baking soda, baking powder and salt. Add grated and undrained zucchini, eggs and 1/3 cup vegetable oil.

Why egg size matters in this recipe:

If you are using smaller eggs, such as store bought white eggs vs. large farm raised brown eggs, you will most likely need to add more oil so that the dry ingredients combine properly and are adequately moistened. The batter should be thinner than cookie dough but a bit thicker than cake or cupcake batter because the zucchini will release its juices as the muffins bake.

Can I use frozen zucchini in these zucchini muffins?

I cannot recommend using frozen zucchini in this recipe as I have only tested this recipe using freshly grated zucchini. However you can freeze the muffins for up to 3 months after they have baked and cooled.

Steps 2-3:

  • Mix the wet and dry ingredients until the batter is well combined. The batter should be somewhat thick because as the zucchini bakes and softens, it will also release moisture into the muffins.
  • Gently fold the chocolate of your choice into the zucchini muffin batter, being careful not to over mix the batter (overmixing muffins can cause them to be tough and to bake unevenly).

Can I use chocolate chips in these zucchini muffins?

My kids love these baking bits so I like to add them for extra fun. The baking bits will lose some of their color as they bake into the muffins, so if you prefer to use chocolate chips instead, you certainly can!

Step 4: Fill lined muffin tins 2/3 full with the zucchini muffin batter and then bake the muffins in the preheated oven for 20-25 minutes until they have puffed up and a toothpick inserted in the center comes out clean.

Are cupcake wrappers necessary for these chocolate zucchini muffins?

I prefer to line my muffin tins with cupcake liners for the easiest removal. If you do not have cupcake liners on hand you can either grease the muffin tins before adding batter or you can cut a small circular piece of parchment paper to line the bottom of the tin and then grease the sides.
