Gluten Free Zucchini Muffins

These gluten free zucchini muffins are incredibly moist, spiced with warm cinnamon, and perfectly domed without any of the gritty texture often found in gluten-free baking.

Why This Recipe Works:

• Salting and squeezing the zucchini removes excess water, preventing a gummy, collapsed center.
• A precise ratio of xanthan gum in the flour blend mimics the gluten structure to trap rising gases.
• Baking at a high initial temperature activates the leavening agents rapidly for high, bakery-style muffin tops.

I still remember the humid July morning I stood over my kitchen sink, squeezing shredded green zucchini in a thin dish towel until my forearms literally shook and my knuckles turned white.

I was determined to make a muffin that didn't taste like wet cardboard.

Gluten-free baking is notoriously tricky because without the gluten protein matrix to trap steam, the heavy moisture from summer squash usually turns the crumb into a gummy, sad puddle. Bear with me here: I tested this with four different flour blends, and most of them failed because the starch gelatinization went completely haywire under the weight of the water.

The simple fix is a two-step moisture extraction process combined with Bob's Red Mill 1-to-1 Baking Flour.

By salting the grated zucchini with Diamond Crystal kosher salt and squeezing it dry, we control the hydration perfectly, yielding a bakery-style dome that holds its shape for days.

Ingredients

• 2 cups Bob's Red Mill 1-to-1 Gluten-Free Baking Flour
• 1 tsp baking soda
• 1/2 tsp baking powder
• 1 1/2 tsp ground cinnamon
• 1/2 tsp Diamond Crystal kosher salt (plus extra for sweating zucchini)
• 1 1/2 cups grated zucchini (about 1 medium zucchini)
• 1/2 cup granulated sugar
• 1/2 cup packed light brown sugar
• 1/2 cup neutral oil (like avocado or canola oil)
• 2 large eggs, room temperature
• 1 tsp pure vanilla extract
• 1/2 cup chopped walnuts or chocolate chips (optional)

Directions

1. Preheat oven to 425°F (218°C) and line a 12-cup muffin tin with paper liners.
2. Grate the zucchini and place it in a colander. Toss with a pinch of salt and let sit for 10 minutes, then wrap in a clean kitchen towel and squeeze out as much liquid as humanly possible.
3. In a large bowl, whisk together the gluten-free flour, baking soda, baking powder, cinnamon, and salt.
4. In a separate bowl, whisk the granulated sugar, brown sugar, oil, eggs, and vanilla extract until smooth.
5. Pour the wet ingredients into the dry ingredients and fold gently with a spatula until just combined. Fold in the squeezed zucchini and optional walnuts.
6. Divide the batter evenly among the 12 muffin cups.
7. Bake at 425°F for 5 minutes, then lower the oven temperature to 350°F (177°C) without opening the oven door, and bake for an additional 13-15 minutes until a toothpick inserted in the center comes out clean.
8. Let the muffins cool in the pan for 5 minutes, then transfer to a wire rack to cool completely.

Notes

• I highly recommend Bob's Red Mill 1-to-1 Gluten-Free Baking Flour (the blue bag). If using another brand, ensure it contains xanthan gum, or add 1/4 teaspoon of xanthan gum separately.
• Squeezing the zucchini is non-negotiable. Zucchini is roughly 95% water; if you skip this, the excess moisture will dissolve the starch structure during baking, leaving you with dense, sunken centers.
• Do not open the oven door when lowering the temperature from 425°F to 350°F. That initial blast of high heat vaporizes the moisture and expands the air pockets for a high rise, and dropping the oven's thermal mass too quickly will cause them to deflate.
• Gluten-free baked goods tend to dry out faster than wheat-based ones. Keep these in an airtight container with a paper towel to absorb any residual moisture that migrates to the surface over 48 hours.

Serving Suggestions

These muffins are spectacular warm, but you can easily turn them into a full breakfast spread or a cozy afternoon snack with these pairing ideas.

• Slathered with salted grass-fed butter or a smear of cream cheese.
• Alongside a warm, frothy Cherry Vanilla Latte for a perfect morning ritual.
• Drizzled with a touch of warm honey or maple syrup.
• Served as a sweet contrast next to savory Baked Mushroom Egg Cups.
• Paired with a fresh, vibrant Fresh Fruit Bowl to balance the warm cinnamon spices.

Storage and Reheating

Let them cool completely first.

If you pack them up while they are even slightly warm, the trapped steam will turn the crusts incredibly soggy by tomorrow morning. Store them in an airtight container at room temperature for up to three days, lining the bottom with a paper towel to catch any escaping moisture.

For longer storage, these muffins freeze beautifully. Wrap each muffin tightly in plastic wrap, place them in a freezer bag, and freeze for up to three months.

When you're ready to eat, skip the microwave if you want to preserve that delicate crumb. Instead, pop them into a 350°F oven or toaster oven for about five minutes to restore that fresh-baked warmth and crisp up the edges.

Ingredient Substitutes

If you need to swap things around based on what's in your pantry, here are the most reliable substitutions I've tested.

1. The Flour: If you aren't gluten-free, you can swap the 1-to-1 flour for standard all-purpose flour cup-for-cup.
2. The Oil: Melted coconut oil or unsalted butter can replace the neutral oil, though butter will make the crumb slightly denser.
3. The Sugar: You can use all coconut sugar instead of the white and brown sugar mix, which gives a deeper, caramel-like flavor.
4. The Mix-ins: Swap the walnuts for dark chocolate chips if you want a sweeter treat, similar to our Chocolate Zucchini Muffins Gluten Free.

There is something incredibly satisfying about watching these rise in the oven, knowing you successfully tamed the wild moisture of summer squash. Let me know if you try them, and happy baking!
