The chocolatey oat clusters are also naturally gluten-free if you ensure your oats are certified gluten-free, making them accessible to many dietary preferences.

Ingredient List

• 1 cup rolled oats (not instant; provides the perfect chewy texture)
• 8 tablespoons golden monkfruit sweetener (see notes for alternatives)
• 4 tablespoons cocoa powder (unsweetened for rich chocolate flavor)
• Pinch of salt (balances sweetness and enhances flavor)
• 1 1/2 teaspoons vanilla extract (adds warmth and depth)
• 1/4 cup olive oil (use extra virgin for a subtle fruity note)
• 2 egg whites (helps bind ingredients and add lightness)

Prep & Cook Tools

• Mixing bowl: A medium bowl for combining ingredients easily.
• Whisk or fork: To blend the wet ingredients smoothly.
• Baking sheet: Lined with parchment paper or a silicone baking mat to prevent sticking.
• Spoon or cookie scoop: For portioning the cookie clusters evenly.
• Oven: Preheated to 325°F (163°C) for perfect baking.

Method: Sugar-Free Flourless Chocolate Oatmeal Cluster Cookies

Step 1: Preheat and Prepare

Preheat your oven to 325°F (163°C). Line a baking sheet with parchment paper or a silicone baking mat to keep your cookies from sticking and to make cleanup a breeze.

Step 2: Mix Dry Ingredients

In your mixing bowl, combine the rolled oats, cocoa powder, golden monkfruit sweetener, and a pinch of salt. Stir them together until they’re evenly distributed. This ensures every bite of your Sugar-Free Flourless Chocolate Oatmeal Cluster Cookies is balanced and flavorful.

Step 3: Whisk Wet Ingredients

In a separate bowl or directly in the dry ingredients bowl if you prefer, whisk the egg whites, olive oil, and vanilla extract together until smooth. The egg whites add structure without heaviness, and the olive oil keeps the cookies moist.

Step 4: Combine and Form Clusters

Pour the wet mixture into the dry ingredients and stir until just combined. The batter will be thick and sticky—perfect for creating those delightful clusters. Using a spoon or cookie scoop, drop spoonfuls onto your prepared baking sheet, spacing them about an inch apart because these cookies don’t spread much.

Step 5: Bake to Perfection

Bake for 15-18 minutes, or until the edges are set but the centers still look slightly soft. Avoid overbaking to retain that chewy cluster texture that makes these cookies so addictive.

Step 6: Cool and Enjoy

Let the cookies cool on the baking sheet for 5 minutes before transferring them to a wire rack. As they cool, they firm up perfectly. These clusters are delicious warm or at room temperature.

Spring–Summer–Fall–Winter Ideas

• Spring: Add a sprinkle of chopped fresh mint or a few crushed freeze-dried raspberries for a bright twist.
• Summer: Mix in some chopped nuts or seeds to add crunch and nutrition for a perfect picnic snack.
• Fall: Stir in cinnamon and a pinch of nutmeg to embrace cozy seasonal spices.
• Winter: Top clusters with a tiny drizzle of melted dark chocolate or sprinkle with shredded coconut for festive flair.

Mistakes Even Pros Make

• Using instant oats instead of rolled oats — Instant oats can make the texture mushy and less cluster-like.
• Overbaking — The cookies will dry out and lose their chewy texture if left in the oven too long.
• Skipping the pinch of salt — Salt is essential to balance the sweetness and deepen the chocolate flavor.
• Using regular sugar instead of monkfruit sweetener — This changes the sugar-free nature of the cookies and can affect the texture.

Storage Pro Tips

Store your Sugar-Free Flourless Chocolate Oatmeal Cluster Cookies in an airtight container at room temperature for up to 5 days. For longer storage, pop them in the refrigerator for up to 2 weeks or freeze them in a sealed container or bag for up to 3 months. When ready to enjoy, simply thaw at room temperature or warm slightly in the microwave for that freshly-baked feel.

Reader Q&A

Can I substitute the olive oil with another type of oil?

Absolutely! You can use avocado oil, melted coconut oil, or even a neutral oil like grapeseed. Just keep in mind that coconut oil will add a slight coconut flavor, while others will keep the taste neutral.

Are these cookies suitable for people with gluten intolerance?

Yes, as long as you use certified gluten-free rolled oats, these cookies are naturally gluten-free since they contain no flour.

Can I make these cookies vegan?

Since this recipe relies on egg whites for structure, you can try using aquafaba (the liquid from canned chickpeas) as a vegan substitute. Whip 3 tablespoons of aquafaba until frothy and use it in place of the egg whites, but note that texture may vary slightly.

What is the best way to measure rolled oats for this recipe?

Use a standard measuring cup and lightly spoon the oats into it without packing them down, then level off with the back of a knife. This ensures you get the correct 1 cup measurement for the perfect cookie texture.
