Ingredients:
- 1 cup (100g) instant oats
- ¾ cup (90g) whole wheat flour or gluten-free* flour
- 1 ½ tsp baking powder
- 1 ½ tsp ground cinnamon
- ¼ tsp ground nutmeg
- ¼ tsp salt
- 2 tbsp (28g) coconut oil or unsalted butter, melted and cooled slightly
- 1 large egg, room temperature
- 1 tsp vanilla extract
- ½ cup (120mL) pure maple syrup
- 1 cup (90g) freshly grated zucchini, patted dry ((see Notes!))
Instructions:
Preparation and Mixing Dry Ingredients
- Preheat your oven and prepare your baking sheets. Before you even start gathering your ingredients, it’s always a good idea to get your oven preheating. Set it to 350°F (175°C). Then, line two baking sheets with parchment paper. This step is crucial as it prevents the cookies from sticking and makes cleanup a breeze. Parchment paper also helps ensure the bottoms of your cookies bake evenly and don’t get too dark.
- Whisk together the dry ingredients. In a large mixing bowl, combine the instant oats, whole wheat flour (or your chosen gluten-free alternative), baking powder, ground cinnamon, ground nutmeg, and salt. Give everything a good whisk to ensure the leavening agent and spices are evenly distributed throughout the flour mixture. This ensures that every cookie rises properly and has a balanced flavor. If you’re using gluten-free flour, make sure it’s a blend that works well for baking, as some gluten-free flours can lead to a slightly different texture.
Combining Wet Ingredients and Adding Zucchini
- Mix the wet ingredients. In a separate medium-sized bowl, whisk together the melted and slightly cooled coconut oil or unsalted butter, the room temperature large egg, and the vanilla extract. Whisk until these ingredients are well combined and the egg is fully incorporated. It’s important that your egg is at room temperature for better emulsification with the fats, leading to a smoother batter.
- Incorporate the maple syrup and then the zucchini. Add the pure maple syrup to the wet ingredients and whisk again until everything is smooth and homogenous. Now comes the star ingredient: the freshly grated zucchini. Ensure your zucchini is patted dry to remove as much excess moisture as possible. This is a really important step to prevent soggy cookies. You can do this by wrapping the grated zucchini in a clean kitchen towel or paper towels and gently squeezing out the liquid. Add the prepared zucchini to the wet ingredients and stir it in gently until it’s evenly distributed. The zucchini might not look like it’s disappearing completely, and that’s perfectly fine; its moisture and tenderizing power will work its magic as the cookies bake.
Forming and Baking the Cookies
- Combine wet and dry mixtures and form cookies. Add the wet ingredients mixture to the bowl containing the dry ingredients. Stir everything together with a spatula or wooden spoon until just combined. Be careful not to overmix the batter, as this can lead to tough cookies. You should have a thick, slightly wet batter. Using a cookie scoop or two spoons, drop rounded tablespoons of the cookie dough onto the prepared baking sheets, leaving about 2 inches of space between each cookie to allow for spreading. You can gently flatten the tops of the cookies with the back of the spoon if you prefer a flatter cookie, but they will spread slightly on their own.
- Bake until golden brown. Place the baking sheets in the preheated oven and bake for 12-15 minutes, or until the edges are lightly golden brown and the centers are set. The exact baking time will depend on your oven and the size of your cookies. Keep an eye on them towards the end of the baking time. Once they’re done, remove the baking sheets from the oven and let the cookies cool on the sheets for about 5 minutes before transferring them to a wire rack to cool completely. This initial cooling on the baking sheet helps them firm up enough to be moved without breaking.
These healthy zucchini oatmeal cookies are best enjoyed warm or at room temperature. They store well in an airtight container at room temperature for up to 3 days, or you can refrigerate them for a slightly longer shelf life. You can also freeze the baked cookies for up to 2 months. Enjoy this guilt-free indulgence!

Frequently Asked Questions:
Can I use a different type of flour?
Absolutely! While whole wheat flour is fantastic, you can also use oat flour for an even more oat-centric cookie, or a gluten-free blend if needed. Just be mindful that different flours might absorb moisture slightly differently, so you may need to adjust the liquid content a tiny bit.
How should I store these cookies?
Store your cooled cookies in an airtight container at room temperature for up to 3 days, or in the refrigerator for up to a week. They also freeze beautifully! Simply place them in a freezer-safe bag or container, and they’ll stay fresh for up to 3 months. Just let them thaw at room temperature before enjoying.
Will the zucchini make the cookies taste like vegetables?
Not at all! The zucchini is finely shredded and its flavor is very mild, especially when combined with the sweetness of the oats and any optional add-ins like cinnamon or vanilla. Its primary role is to add moisture and a healthy boost, resulting in wonderfully soft and chewy cookies.
