My kids have never been excited about zucchini, which is a little disappointing because I love almost every kind of summer squash. Zucchini is one of those simple garden ingredients that works beautifully in both savory dishes and sweet baked goods, especially when it is shredded into quick breads and muffins.
Still, I cannot complain too much. They do eat plenty of other vegetables, and I know not every food is going to be an instant favorite. But zucchini? That one has always been a hard sell in our house.

When my kids pushed their chairs up to the cupboard to “help” me bake, they were very interested in what we were making. That interest faded quickly when I told them the pile of shredded zucchini on the counter was going straight into the muffin batter. The dramatic gagging noises started immediately.
I tried to explain that they would not really taste the zucchini. In gluten-free zucchini muffins, the shredded squash mostly adds moisture and tenderness. It blends into the batter, softens as it bakes, and helps create a muffin that is not dry or crumbly. But no matter how many times I said that, they insisted they were not going to try even one bite.
Then the muffins went into the oven, and everything changed. The warm smell of cinnamon, vanilla, and brown sugar began drifting through the kitchen. Suddenly, the idea of zucchini in muffins did not seem quite so terrible.

What’s the verdict on the zucchini?
Their confidence started to waver as soon as the muffins came out of the oven. Hadassah finally decided she could risk a small piece, especially if we added enough butter. One small bite turned into another, and before long, the gluten-free zucchini streusel muffins were disappearing fast.
All right, they did not literally vanish in seconds. But the muffins I did not set aside for the next morning’s breakfast were gone before I knew it. That is always the best kind of review, especially from kids who claimed they would never eat zucchini.

This gluten-free zucchini streusel muffin recipe is simple to make, even though the ingredient list looks a little long at first glance. The batter comes together with gluten-free flour, cinnamon, shredded zucchini, banana, eggs, oil, and vanilla. The streusel topping adds a sweet, crumbly finish that makes these muffins feel extra special without making the recipe complicated.
The result is a batch of soft, moist gluten-free zucchini muffins with a warm cinnamon flavor and a tender crumb. They are perfect for breakfast, an afternoon snack, or a make-ahead treat to enjoy with coffee or tea. If you are trying to use up extra zucchini, this is a delicious way to turn it into something the whole family may actually look forward to eating.

- Cook Time: 15-20 minutes
- Total Time: 35-40 minutes
- Yield: 18 muffins
Ingredients
- 3 cups gluten-free flour mix
- 1 tsp. guar or xanthan gum, omitted if your flour mix already contains it
- 1 tsp. salt
- 1 tsp. baking soda
- 2 tsp. cinnamon
- 1 cup evaporated cane juice
- 2 ½ cups shredded zucchini
- 3 eggs
- 1 banana
- 1/4 cup oil, such as light olive oil
- 2 tsp. vanilla
Topping:
- 1/3 cup butter
- 1/2 cup gluten-free flour, not starch
- 1/2 cup brown sugar or evaporated cane juice
- 2 Tablespoons cinnamon
Instructions
- Preheat the oven to 350º.
- In a large bowl, mix the gluten-free flour, guar or xanthan gum, salt, baking soda, cinnamon, and evaporated cane juice. Set the dry mixture aside.
- Mash the banana well, or blend it in a food processor if you prefer a smoother texture.
- Beat in the eggs, oil, and vanilla. If using a food processor, pulse just until combined.
- Shred the zucchini and add it to the banana, egg, oil, and vanilla mixture.
- Pour the wet ingredients over the dry ingredients. Mix until everything is combined, using a rubber spatula to scrape up any flour from the bottom of the bowl.
- Divide the batter evenly among 18 greased muffin cups.
- Combine the streusel topping ingredients until crumbly, then divide the topping evenly over the muffin batter.
- Place the muffin pans in the center of the preheated oven. Bake until the tops are golden brown and a toothpick inserted in the center of a muffin comes out clean, about 15-20 minutes.
- Remove the muffins from the oven and let them cool in the pans for 10 minutes.
- Loosen the edges with a butter knife, then transfer the muffins to a wire cooling rack to finish cooling.
- For the neatest texture, let the muffins cool completely before serving. But if warm gluten-free zucchini muffins with butter sound too tempting to wait for, enjoy them right away.
These gluten-free zucchini streusel muffins are especially good when served warm, but they also make a practical breakfast to save for the next day. The zucchini keeps the muffins tender, the banana helps add moisture, and the cinnamon streusel gives each muffin a sweet bakery-style topping. Even if your family is unsure about zucchini, this recipe may be the one that changes their minds.
