Ingredients needed

As mentioned earlier, this recipe calls for pantry staple ingredients that you’ll likely already have on hand. Here is what you’ll need: 

Rolled Oats (Old fashioned oats). Instead of using flour, we use oats that add fiber, protein and give these cookies a chewy texture. Quick oats will also work, but the cookies will be a little softer.  Peanut Butter or alternative. Adds a healthy fat element that adds flavor and gives the cookies more staying power. If you can’t tolerate peanut butter, try almond butter or tahini.  Banana. Mashed banana keeps the cookies soft while also adding sweetness. The riper the banana, the sweeter the cookies will be.  Shredded Zucchini. Finely grated zucchini with the moisture removed.  Mix-ins. Chopped nuts, candy, dried fruit, etc.

Tips to make the best zucchini chocolate chip cookies

Ensure you squeeze out all the moisture from the zucchini before adding it to the cookie batter. This ensures the cookies will be moist and chewy, without spreading and sinking once baked. Do not overbake the cookies; they will continue to firm up once cooling. These cookies can be made 100% nut free. Simply replace the peanut butter with one of the following- Sunflower seed butter, wow butter, or tahini. A mashed, overripe banana is preferred, but you can replace it with unsweetened applesauce. Start with 1 1/4 cups and adjust accordingly. These oatmeal zucchini cookies are naturally sweetened. Add a dash of maple syrup or some agave nectar for sweeter cookies.  Add a drizzle of melted white chocolate or spread some cream cheese frosting on top for an extra layer of decadence.

Storage instructions

To store: Zucchini cookies are best kept refrigerated, as they will keep for at least a week this way. Store leftover cookies in the fridge in a sealed container for up to a week.  To freeze: Wrap portions (aim for 3-4 in a portion) in parchment paper before either placing a sealed container or plastic wrap. This will ensure the cookies remain fresh and void of freezer burns.
