Chocolate Zucchini Muffins
These Chocolate Zucchini Muffins are rich, moist, and oh-so-good. The zucchini adds both extra nutrients and moisture, while cocoa powder and chocolate chips add a bit of rich chocolate decadence.
Have you ever baked with zucchini? These chocolate zucchini muffins are actually the first baked good I’ve made with zucchini but they definitely won’t be the last!
Inspired by my bakery style chocolate muffins, these zucchini muffins are rich, moist, and decadent. And, no – you can’t really taste the zucchini.
Baking with zucchini is actually a sneaky way to add extra moisture into muffins, breads, etc. Plus it adds some extra nutrients because it is a vegetable, after all.
Bake these in a muffin tin, freeze them, then thaw on busy mornings! It’s the perfect way to use up extra zucchini, especially during zucchini season, AND eat vegetables for breakfast!
Chocolate lovers will enjoy the decadent chocolate flavor and soft texture of these delicious muffins!

Recipe FAQs
Here are a few common questions about baking with zucchini.
Do I need to peel the zucchini? No, the skin on zucchini is very soft, so it does not need to be peeled.
Do I need to squeeze the moisture from the zucchini? No, there’s no need to squeeze the grated zucchini to remove the excess moisture. In fact, that moisture is important to keep the muffins moist as they bake.
What should I use to grate zucchini? The easiest way to grate zucchini is using a cheese grater.
To make gluten-free chocolate zucchini muffins, replace the flour with with a one to one gluten free flour mix. I recommend King Arthur’s Measure for Measure Gluten Free Flour.
Tips for the Best Chocolate Zucchini Muffins
Here are a few things to keep in mind for bakery-style chocolate zucchini muffins.
- Let the batter rest. This is key to making sure that the muffins rise nice and tall in the oven.
- Use all of the batter. Yes, all of the batter will fit into 12 liners! It seems like a lot but using all the batter helps produce those bakery-style muffin tops.
- Don’t open the oven when you reduce the heat. When you turn down the heat to 350, resist the urge to peek inside the oven. Wait until they’re almost done to open the oven and check their doneness.
How to Store Homemade Muffins
Muffins can be stored at room temperature for about 3 days in an airtight container. They’ll last an extra day or two in the fridge too. Just let them come to room temperature before serving.
Can I Freeze Zucchini Muffins?
Yes, these chocolate zucchini muffins freeze well. You’ll want to wrap them individually in plastic wrap. Sometimes, I’ll wrap two together, with the bottoms of the muffin liner touching, since I usually want to pull two from the freezer at a time. Wrap them tightly in plastic wrap then place them in an airtight container or freezer-safe bag.
Thaw on the counter to room temperature or pop them in the microwave for 15-second intervals until warmed.
