Moist chocolate zucchini muffins with two kinds of chocolate - chocolate chips and cocoa powder.
These delicious muffins are a perfect way to use up some of that garden zucchini!

Baking with zucchini
Zucchini is one of those magical vegetables that can be used in just about anything! When grated and added to baked goods, it adds moisture and tenderness to whatever you're baking.
These chocolate zucchini muffins are a perfect for using up zucchini when you have a surplus from your garden. But they are also perfect for baking when you don't have a garden at all! I often buy zucchini from the store when I don't have any garden fresh zucchini. It works perfectly in this recipe too.
If you have a non-veggie lover in your household, you might want to peel the zucchini before using. This removes any hint of green from the zucchini. Your non-veggie lover person will never even know there's zucchini in these muffins!
When you first mix this muffin batter together, you'll be convinced it's too dry. Once you add the zucchini, you give it a quick stir and then wait. When you come back a few minutes later and stir it again, you'll find the zucchini has released some of its moisture and the batter is just perfect!

Amazing!!! So delicious! I’m going to recommend it to everyone!
I used whole wheat flour and milk instead of buttermilk because I didn’t have it at home. Had to put one cup of milk instead of half because it was too dry but then it was perfect !!
Kathy says
Thanks! I love the idea of using whole wheat flour. It is denser so more milk would be needed. Sounds like you adjusted it perfectly! Thanks for leaving a comment!!! 🙂
