Moist Gluten-Free Zucchini Cookies

You know what’s amazing about these zucchini cookies? They’re proof that gluten-free baking doesn’t have to be complicated or taste like cardboard. I started making these when my neighbor shared some extra garden zucchini with me last summer, and now they’re a regular in my cookie rotation.

They’re perfect for those times when you want something sweet but don’t want to feel guilty about having seconds. Plus, they’re a sneaky way to get some veggies into picky eaters – my kids don’t even notice the zucchini! I like to make a big batch on Sunday afternoons while I’m meal prepping for the week.

Whether you’re gluten-free by choice or necessity, or just looking for a new cookie recipe to try, these soft, chewy treats might become your new go-to. They’re simple enough for beginner bakers but tasty enough to share at your next potluck or family gathering.

What Kind of Zucchini Should I Use?

For these cookies, medium-sized zucchini are your best bet since they tend to have fewer seeds and more flesh than larger ones. Look for zucchini that are firm to the touch and about 6-8 inches long – the really big ones can be watery and less flavorful. After grating, it’s super important to pat the zucchini dry with paper towels or a clean kitchen towel to remove excess moisture, which could make your cookies too wet. If you’re shopping out of season, you can actually use frozen shredded zucchini – just thaw it completely and squeeze out all the liquid before measuring.

Options for Substitutions

Here’s what you need to know about swapping ingredients in these cookies:

• Gluten-free flour blend: While Cup4Cup works great, you can use other gluten-free flour blends like Bob’s Red Mill 1-to-1 or King Arthur Measure for Measure. Just make sure your blend contains xanthan gum – if it doesn’t, add 1/4 teaspoon to the recipe.
• Butter: For dairy-free cookies, swap butter with softened coconut oil or dairy-free butter sticks. The texture might be slightly different, but they’ll still be yummy!
• Maple syrup: You can use honey or agave nectar instead. The flavor will change slightly, but both options work well as natural sweeteners.
• Chocolate chips: Feel free to use all regular-sized or all mini chips if that’s what you have. You can also try dairy-free chocolate chips, white chocolate, or even chopped nuts for a different twist.
• Zucchini: This is a key ingredient that adds moisture and can’t really be substituted. Just make sure to squeeze out excess moisture really well before using.
• Quick oats: While quick oats give the best texture, you can use old-fashioned oats – just pulse them in a food processor a few times to break them down slightly. Remember to check for gluten-free certification!

Watch Out for These Mistakes While Baking

The biggest challenge when making zucchini cookies is dealing with excess moisture – be sure to thoroughly pat dry your grated zucchini with paper towels or even squeeze it in a clean kitchen towel, as too much moisture will make your cookies spread too thin and become cake-like. The second common mistake is using cold ingredients, so make sure your butter and eggs are at room temperature for at least 30 minutes before starting, which helps create a better cookie texture. When working with gluten-free flour, avoid overmixing the dough as this can make your cookies tough – mix just until the ingredients are combined, and remember that gluten-free dough often benefits from a 15-30 minute rest in the refrigerator before baking. For the best texture, take the cookies out when they still look slightly underdone in the center (around 12-14 minutes at 350°F), as they’ll continue to set while cooling on the baking sheet.

What to Serve With Zucchini Cookies?

These soft and sweet zucchini cookies are perfect for an afternoon snack or dessert, and they pair wonderfully with a cold glass of milk (regular, almond, or oat milk all work great!). If you’re serving these for dessert, try them slightly warm with a scoop of vanilla ice cream on top – the contrast between warm cookie and cold ice cream is so good. For a cozy afternoon treat, serve them alongside your favorite hot beverage like coffee, tea, or even hot chocolate. Since these cookies already pack some nutrition from the zucchini and oats, they make a satisfying standalone snack too!

Storage Instructions

Keep Fresh: Once your zucchini cookies have cooled completely, place them in an airtight container. They’ll stay fresh at room temperature for up to 3 days. Because they contain fresh zucchini, you might want to pop them in the fridge after day 2, where they’ll last for up to a week.

Freeze: These cookies are perfect for freezing! Place them in a freezer-safe container with parchment paper between layers to prevent sticking. They’ll keep well for up to 3 months. I like to make a double batch and freeze half for when those cookie cravings hit!

Thaw: When you’re ready to enjoy your frozen cookies, just take out what you need and let them thaw at room temperature for about 30 minutes. If you like them slightly warm, give them a quick 10-second zap in the microwave – the chocolate chips get all melty and nice!

Ingredients

• 1/2 tsp baking soda
• 1/2 cup brown sugar
• 1 1/2 tsp vanilla essence (I use Nielsen-Massey Vanilla Extract)
• 1/2 tsp cinnamon
• 1/2 cup white sugar
• 1 cup semi-sweet chocolate chips (good quality for melting)
• 2 tbsp maple syrup (grade A pure maple syrup)
• 1 large egg (at room temperature)
• 1 cup grated zucchini (excess moisture squeezed out)
• 2 cups gluten-free quick oats
• 1 cup gluten-free all-purpose flour (I use Bob’s Red Mill 1-to-1 Baking Flour)
• 1/2 cup unsalted butter (softened to room temperature)
• 1/2 tsp salt

Step 1: Prepare Ingredients and Equipment

Preheat your oven to 350°F (175°C).

Line your baking sheets with parchment paper or use silicone baking mats to ensure the cookies don’t stick.

Begin by grating the zucchini.

Transfer the grated zucchini to a paper towel or clean dish towel and gently blot to remove excess moisture.

Set it aside for later use.

Step 2: Cream Butter and Sugars

In a large mixing bowl, beat together the softened butter, brown sugar, and granulated sugar.

Continue to beat for about 3 minutes, until the mixture becomes light and creamy.

This step ensures the structure of your cookies by incorporating air into the dough.

Step 3: Incorporate Wet Ingredients

Add the egg, vanilla extract, and maple syrup to the creamed butter and sugar mixture.

Beat until everything is well combined and smooth.

This step ensures that all wet ingredients are evenly distributed within the dough.

Step 4: Add Dry Ingredients

Mix in the oatmeal, flour, baking soda, cinnamon, and salt.

Stir everything until just mixed, ensuring there are no flour streaks left.

Then, gently fold in the grated zucchini and chocolate chips, making sure they are evenly distributed throughout the dough.

Step 5: Shape and Bake the Cookies

Use a medium cookie scoop or measure out heaping 1 1/2 tablespoons of dough.

Place the scoops about 2 inches apart on the prepared baking sheets.

Bake the cookies in the preheated oven for 13-15 minutes, rotating the sheets halfway through the baking time.

The cookies are done when the edges are set and the centers just start to set.

Step 6: Cool and Enjoy

Allow the cookies to cool on the baking sheets for about 15 minutes.

This initial cooling time helps the cookies set and makes them easier to transfer.

Afterward, move the cookies to a wire rack to cool completely.
