Ingredients You’ll Need
What makes a great cookie? It starts with great ingredients, and this recipe is no exception. Every element has a special part to play, from the oats that bring a hearty chew to the peanut butter that gives these cookies their rich, nutty goodness.
- Old-fashioned whole rolled oats (1 cup / 85g): These oats provide texture and a wholesome base without any flour.
- Baking soda (1 teaspoon): The leavening agent that helps the cookies rise perfectly and become soft inside.
- Ground cinnamon (1/4 teaspoon): A subtle warm spice that complements the peanut butter beautifully.
- Salt (1/8 teaspoon): Just enough to enhance the flavors and balance the sweetness.
- Large eggs (2, room temperature): They bind everything together and add a lovely tenderness.
- Natural peanut butter (1 cup / 250g, room temperature): The star ingredient, delivering creamy peanut flavor and moisture.
- Light or dark brown sugar (2/3 cup / 133g): Adds sweetness and a bit of chewiness to the cookies.
- Pure vanilla extract (2 teaspoons): Adds depth and warmth to the overall flavor.
- Semi-sweet chocolate chips (2/3 cup / 120g): The irresistible pockets of melty chocolate that make these cookies unforgettable.
How to Make Flourless Peanut Butter Oatmeal Cookies Recipe
Step 1: Combine Your Dry Ingredients
Start by whisking together the oats, baking soda, cinnamon, and salt in a medium bowl. This blend is the foundation that will give your cookies their characteristic texture and subtle spicy note.
Step 2: Mix the Wet Ingredients
In another bowl, whisk the eggs until smooth. Add in the peanut butter, brown sugar, and vanilla extract, then stir them together until the mixture is fully combined and luscious. This creamy wet base holds the cookies together once mixed with the dry ingredients.
Step 3: Blend Everything Into Cookie Dough
Pour the oat mixture into the wet peanut butter blend and stir until just combined—don’t be shy, it does take some arm muscle! Then fold in the chocolate chips, those delicious bursts of sweetness that will melt in your mouth.
Step 4: Chill for Perfect Texture
Cover your dough and place it in the fridge for at least 30 minutes, or up to 3 days. Chilling helps the flavors meld and gives the cookies the perfect soft but firm texture after baking.
Step 5: Get Ready to Bake
Preheat your oven to 350°F (177°C) and line your baking sheets with silicone mats or parchment paper for easy cleanup and even baking.
Step 6: Shape and Bake the Cookies
Once chilled, scoop out about 1.5 tablespoons of dough per cookie onto your lined baking sheets. Press down gently with a spoon to slightly flatten them—this helps the cookies spread and bake evenly. If your dough has been in the fridge for longer than an hour, let it warm up at room temperature for 20 minutes first so your cookies don’t stay too puffy.
Step 7: Bake and Cool
Bake for 12 to 14 minutes, or until the cookie edges are set and the centers still look soft. This ensures a chewy center that’s absolutely divine. Let them cool on the baking sheet for about 10 minutes before moving to a wire rack. Feel free to press a few extra chocolate chips on top while they’re warm for that extra eye-catching touch!
How to Serve Flourless Peanut Butter Oatmeal Cookies Recipe
Garnishes
A simple sprinkle of flaky sea salt or a few extra chocolate chips on each cookie right after baking elevates their flavor and makes these cookies look even more tempting. You could also drizzle a bit of melted peanut butter or even some dark chocolate for indulgence.
Side Dishes
Serve these cookies alongside a cold glass of milk, a cup of hot coffee, or your favorite herbal tea. The nutty, sweet flavors pair beautifully with a comforting beverage, making your snack an irresistible mini-treat.
Creative Ways to Present
Stack your cookies on a pretty plate with some fresh berries or sliced bananas for a colorful twist. Or sandwich peanut butter and jelly right between two cookies for a nostalgic spin on a classic flavor combo. They also make delightful gifts wrapped in parchment paper with a cute ribbon!
Make Ahead and Storage
Storing Leftovers
Once cooled, store any leftover cookies in an airtight container at room temperature. This keeps them fresh and chewy for up to one week, ready when sweet cravings strike again.
Freezing
If you want to keep these favorites for longer, freeze them in a single layer on a baking sheet first, then transfer to a freezer bag. They freeze beautifully for up to three months and thaw quickly at room temperature when you’re ready to enjoy.
Reheating
Warm your cookies gently in the microwave for about 10 seconds or toss them in a low oven for a few minutes. This revives their soft, melty texture and makes the chocolate chips perfectly gooey again.
FAQs
Are these cookies truly flourless?
Yes! Instead of traditional flour, this recipe uses rolled oats, which provide structure and texture without any wheat flour, making it suitable for those avoiding gluten.
Can I use crunchy peanut butter?
Absolutely! Using crunchy peanut butter will add even more texture and nutty flavor to your cookies. Just be aware it might slightly change the chewiness.
What if I don’t have chocolate chips?
No problem! You can substitute with chopped nuts, dried fruit, or skip the add-ins altogether. Each variation still offers a delicious cookie experience.
How do I make these cookies vegan?
To make a vegan version, you can try substituting the eggs with flax eggs or another egg replacer, and ensure your peanut butter and chocolate chips are dairy-free.
Why do I need to chill the dough?
Chilling the dough helps the fats solidify and flavors meld. It ensures your cookies don’t spread too much and bake up with a perfect soft but firm texture.

These Flourless Peanut Butter Oatmeal Cookies are a deliciously chewy and naturally gluten-free treat, combining wholesome oats with rich peanut butter and sweet chocolate chips. Perfect for those looking for a simple, flour-free cookie recipe that’s easy to make and full of comforting flavors.
- Total Time: 1 hour (including chilling time)
- Yield: 14 cookies
Ingredients
Dry Ingredients
- 1 cup (85g) old-fashioned whole rolled oats
- 1 teaspoon baking soda
- 1/4 teaspoon ground cinnamon
- 1/8 teaspoon salt
Wet Ingredients
- 2 large eggs, at room temperature
- 1 cup (250g) natural peanut butter, at room temperature
- 2/3 cup (133g) packed light or dark brown sugar
- 2 teaspoons pure vanilla extract
Add-ins
- 2/3 cup (120g) semi-sweet chocolate chips
Instructions
- Mix Dry Ingredients: In a medium bowl, whisk together the oats, baking soda, cinnamon, and salt until well combined. Set this mixture aside to incorporate later.
- Combine Wet Ingredients: In another medium bowl, whisk the eggs until smooth. Using a silicone spatula, blend in the peanut butter, brown sugar, and vanilla extract until the mixture is fully combined and creamy.
- Combine Wet and Dry: Gradually pour the dry oat mixture into the peanut butter mixture. Stir thoroughly until all ingredients are evenly combined, which may require some elbow grease. Gently fold in the chocolate chips to distribute them throughout the dough.
- Chill the Dough: Cover the dough and place it in the refrigerator to chill for at least 30 minutes, or up to 3 days. This helps the dough firm up for easier shaping and better cookie texture.
- Prepare to Bake: Preheat your oven to 350°F (177°C). Line large baking sheets with silicone mats or parchment paper to prevent sticking.
- Shape the Cookies: Remove the dough from the refrigerator. If it has chilled for more than an hour, let it rest at room temperature for about 20 minutes to soften, allowing the cookies to spread properly. Scoop portion sizes of about 1.5 tablespoons (30g) each onto the prepared baking sheets. Using the back of a spoon, gently press down each dough ball to slightly flatten.
- Bake: Place the baking sheets in the oven and bake the cookies for 12–14 minutes, or until the edges are set but the centers remain soft. This ensures a chewy texture once cooled.
- Cool and Finish: Allow the cookies to cool on the baking sheet for 10 minutes. Optionally, press a few extra chocolate chips on top of the warm cookies for an attractive finish. Then transfer the cookies to a wire rack to cool completely, during which time they will slightly deflate.
- Store: Store any leftover cookies tightly covered at room temperature for up to 1 week to maintain freshness and flavor.
Notes
- Using natural peanut butter enhances the flavor and texture of the cookies.
- Letting the dough rest before baking is crucial to allow cookies to spread and bake evenly.
- Chilling the dough for longer improves flavor and texture but adjust the softening time if chilled more than an hour.
- These cookies are naturally gluten-free due to the lack of flour, but always ensure oats are certified gluten-free if needed.
- Pressing extra chocolate chips on top is optional but adds a nice aesthetic touch.
