Ingredients

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

Wet Ingredients

How to Make Healthy Zucchini Oatmeal Cookies

Step 1: Prepare the Dough

In a medium bowl, whisk together the oats, flour, baking powder, cinnamon, nutmeg, and salt. In another bowl, whisk together the coconut oil or butter, egg, and vanilla until fully combined. Stir in the maple syrup. Gradually add the oat mixture into this bowl while stirring until just incorporated. Finally, fold in the grated zucchini. Chill the cookie dough for 30 minutes.

Step 2: Preheat the Oven

Preheat your oven to 325°F (163°C). Line a baking sheet with a silicone baking mat or parchment paper to prevent sticking.

Step 3: Shape the Cookies

Using a spoon and spatula, drop rounded scoops of cookie dough onto the prepared baking sheet—aim for about 15 scoops. Flatten each scoop to approximately ⅜”-thick using your spatula.

Step 4: Bake Your Cookies

Bake at 325°F (163°C) for 11-14 minutes until they’re golden brown around the edges. Once baked, allow them to cool on the pan for about 10 minutes before transferring them onto a wire rack to cool completely.
