Instructions
Mix Dry Ingredients: In a medium bowl, whisk together flour, baking soda, baking powder, salt, cinnamon, and nutmeg until well combined.
Cream Butter and Sugar: In a large bowl, use a hand or stand mixer to cream softened butter and brown sugar until light and fluffy, about 2 minutes. Add whole egg and vanilla extract, mixing until smooth.
Combine Wet and Dry: Gradually add the dry ingredients to the wet mixture, mixing until just combined. Fold in zucchini, quick-cooking oats, raisins, and up to ½ cup optional add-ins (sweetened coconut , nuts, or chocolate chips).
Chill: Using a 1 ½ tablespoon cookie scoop, portion out the dough onto a lined tray or baking sheet. Cover and refrigerate for at least 1 hour to firm up the dough and enhance texture.
Preheat and Prep: Preheat oven to 350°F (175°C). Line two baking sheets with parchment paper or use nonstick silicone baking sheets to prevent sticking.
Bake: Place chilled dough balls on prepared baking sheets, spacing 2 inches apart. Bake for 12-15 minutes, rotating sheets halfway through, until edges are golden and centers are set.
Cool: Let cookies cool on the baking sheet for 5 minutes before transferring to a wire rack to cool completely.
Notes
Zucchini vs. Yellow Squash: Only squeeze zucchini if it’s visibly wet to maintain the right dough consistency. Yellow summer squash needs squeezing to prevent excess moisture, as in some other recipes.
Chilling: Refrigerating the dough for at least 1 hour enhances flavor and reduces cakiness, creating a chewier texture.
Optional Add-Ins: Keep total add-ins to ½ cup to balance the dough.
Storage: Store cookies between parchment paper in an airtight container at room temperature for up to 3 days, in the fridge for a week, or freeze for up to 3 months.
