Soft, thick and rich s’more zucchini muffins are filled with chocolate, marshmallows and buttery graham cracker cookie crumble. The secret to their moist texture is zucchini.
This s’more zucchini muffins recipe is similar to our Reese’s chocolate zucchini muffins. They are by far my favorite muffins that I’ve made so far. If you’re more into marshmallows than peanut butter, you’ll love these chocolate muffins!

S’more zucchini muffins are my new favorite way to use garden zucchini.
The fact that these chocolate zucchini s’more muffins are also filled with zucchini just helps with the idea that they are a totally acceptable option before 9 AM.
Because zucchini = veggies. And veggies = healthy. How’s my math?
My grandma’s zucchini bread recipe and our peanut butter zucchini bread are two favorites during the summer months.
If you need a little healthy too, make our zucchini pizza casserole, zucchini boats and breakfast egg bake.
Whether summer is coming and you have s’mores on the mind, or it’s too cold or rainy to have a traditional s’more, give these s’more zucchini muffins a try! And then try our chocolate zucchini cake.
Enjoy! -Julie
Ingredients
Freshly grated zucchini works best. If you only have frozen zucchini, allow it to thaw and drain before adding it to the muffin batter.
Coconut oil is a great alternative to vegetable oil canola oil. Melt it down before measuring it out.

- Bake at 425ºF for 5 minutes, then reduce the temperature to 375ºF and bake for another 20 minutes. Do not open the oven, just reduce the temperature. A toothpick inserted into the center of a muffin should come out with a few moist crumbs, but no uncooked batter.
- Allow the muffins to fully cool in the pan before removing them.

Notes
