Easy Decadent Chocolate Zucchini Muffin Recipe

Just because it’s not summer yet is no reason to avoid cooking with everyone’s favorite summer squash! I’ve honestly been on such a zucchini kick lately, we eat it at least once a week. My kids rolled their eyes SO hard when I told them I was making this but they quickly realized this chocolate zucchini muffin recipe is decadent, moist, and delicious. 

This recipe is so easy and so versatile. They would taste amazing with chopped walnuts or pecans. The only reason I didn’t experiment with adding nuts is so I can send these to school with my kids but I will definitely try it out during the summer. If you’re looking for an extra chocolatey touch, you can also sprinkle chocolate chips on the batter once they’re in the muffin liners, before baking.

The batter is thick like brownie batter, so don’t worry! Fill the liners about 2/3 of the way full, that should yield approximately 24 muffins.
