Their rich cocoa flavor, paired with a moist tender crumb, makes them ideal for dessert trays or afternoon snacks. You can serve them straight from the oven or cool them for easy grab-and-go bites.

I first made these one weekend to use up extra zucchini and now my nieces ask for them every time they visit. They’re fun to bake and even more fun to eat.

I love using fresh garden zucchini for these. One summer my toddler helped me grate it and proudly called these green chocolate bites. They’re still one of his favorites.

Storage Tips

Store cooled cakes in an airtight container at room temperature for up to two days. For longer storage freeze them in a single layer then transfer to a freezer bag. Thaw at room temperature or gently warm in the microwave.

Ingredient Substitutions

If zucchini is unavailable use grated carrots for a different flavor. You can also mix in chopped nuts like walnuts or pecans for added texture.

Serving Suggestions

Serve these on a platter dusted with powdered sugar or pair with whipped cream or a scoop of ice cream for a richer dessert. They also make great party favors or lunchbox treats.
