Ingredients You’ll Need

1/2 cup unsalted butter, cut into tablespoon pieces: This will be browned to give the cookies a nutty flavor. Unsalted is best for better control over the sweetness.

1 teaspoon ground cinnamon: Adds warmth and depth to the cookies. A must for a comforting taste!
3/4 teaspoon baking soda: Helps the cookies rise slightly, giving them that nice chewy texture.
1/2 teaspoon salt: Balances the sweetness and enhances the overall flavor.
1/8 teaspoon ground nutmeg, optional: For a hint of spiciness if you’re feeling adventurous.
1/2 cup dark brown sugar: This sugar provides moisture and depth. You can replace it with light brown sugar if needed.
1/4 cup granulated sugar: For added sweetness, combining with brown sugar for a perfect balance.
1 large egg: Binds the ingredients together, contributing to the cookie’s structure.
2 teaspoons vanilla extract: Elevates the flavor profile and rounds out the sweetness.
1 cup shredded zucchini, squeezed to remove excess liquid: Keeps the cookies moist without overpowering them. Use fresh zucchini for the best flavor and texture.
2 cups old-fashioned oats: Provides chewiness and heartiness to the cookies. Avoid instant oats for the best texture.
1 cup semisweet chocolate chips: Definitely the crowd-pleaser—who can resist chocolate?
Flaky sea salt, for sprinkling: A finishing touch that enhances sweetness and adds a gourmet element.

How to Make Brown Butter Zucchini Oatmeal Cookies

Brown the Butter: In a medium saucepan over medium heat, melt the 1/2 cup of unsalted butter. Continue to cook it, swirling the pan occasionally, until the butter turns golden brown and has a nutty aroma. This usually takes about 5-7 minutes. Remove it from heat and let it cool slightly.
Mix Dry Ingredients: In a large mixing bowl, whisk together 1 cup of all-purpose flour, 2 tablespoons of flour, 1 teaspoon of ground cinnamon, 3/4 teaspoon of baking soda, 1/2 teaspoon of salt, and 1/8 teaspoon of ground nutmeg, if using. Set this bowl aside.
Combine Sugars and Egg: In another large bowl, combine 1/2 cup of dark brown sugar and 1/4 cup of granulated sugar. Pour in the browned butter and mix until well combined. Add in 1 large egg and 2 teaspoons of vanilla extract, and beat until light and fluffy.
Incorporate Zucchini: Stir in 1 cup of shredded zucchini, squeezing out any extra moisture before adding. Mix until combined.
Combine Wet and Dry Mixtures: Gradually add the dry ingredient mixture to the wet, stirring until just combined. Then fold in 2 cups of old-fashioned oats and 1 cup of semisweet chocolate chips.
Chill the Dough: For best results, chill the cookie dough for about 30 minutes in the fridge. This helps the cookies maintain their shape while baking.
Preheat Oven: Preheat your oven to 350°F (175°C). Line two baking sheets with parchment paper.
Scoop and Bake: Drop spoonfuls of the chilled dough onto prepared baking sheets, spacing them about 2 inches apart. Sprinkle a little flaky sea salt on top of each cookie.
Bake: Bake for about 12-14 minutes, or until the edges are golden brown, but the centers are still soft. They will firm up as they cool.
Cool Down: Allow the cookies to cool on the baking sheets for a few minutes before transferring them to a wire rack to cool completely. Enjoy the fantastic aroma filling your kitchen!

Storing & Reheating

To keep your cookies fresh, store them at room temperature in an airtight container for up to 3 days. If you want to extend their life, simply refrigerate them, where they’ll last up to a week. Alternatively, you can freeze these cookies for up to 3 months—just place them in a freezer-safe bag or container. When you’re ready to enjoy, warm them in the microwave for about 10-15 seconds or until heated through. Don’t be surprised if the texture changes slightly; a quick warm-up will refresh them nicely!

Chef’s Helpful Tips

Avoid overbaking: Keep an eye on your cookies; they should be golden around the edges and soft in the center for that chewy texture.
Room temperature ingredients help the dough mix better, so try to have the egg and butter at room temp for smoother blending.
If you want a more pronounced chocolate flavor, consider adding another 1/2 cup of chocolate chips!
Slice zucchini thinly and pat it dry with a paper towel first to ensure your cookies don’t end up too soggy.
These cookies are great for freezing as dough as well. Just scoop into balls, freeze until solid, then store in a bag—bake from frozen for 1-2 extra minutes.

The rich, nutty taste of browned butter, paired with the sweetness of zucchini and chocolate chips, creates a cookie worthy of any occasion. Feel free to customize the recipe by adding nuts or swapping chocolate chips for your favorite mix-ins. Baking is all about creativity, and these Brown Butter Zucchini Oatmeal Cookies are no exception. I can’t wait for you to share these with your family and friends. Trust me; they will keep coming back for more!

Recipe FAQs

Can I use shredded zucchini with the skin on?

Absolutely! The skin adds a lovely color and texture to your cookies. Just make sure to wash it well before shredding.

How can I make these cookies gluten-free?

You can easily substitute the all-purpose flour with a 1:1 gluten-free flour blend. Just ensure it contains xanthan gum for the best results.

What’s the best way to measure my ingredients accurately?

Using a kitchen scale is ideal for the most accuracy. If you’re using measuring cups, make sure to spoon the flour into the cup and level it off instead of packing it down.

How do I adjust the sweetness?

If you prefer a less sweet cookie, reduce the granulated sugar to 2 tablespoons and keep the brown sugar the same, as it’s essential for moisture. Enjoy your baking adventure!
