• Vanilla Extract: A splash elevates all the flavors and adds a lovely aroma as the cookies bake.
• Large Eggs: The eggs bind everything together, giving the cookies a just-right pillowy bite.
• Rolled Oats (gluten-free if needed): These add incredible chew and heartiness while keeping the cookies flourless.
• Baking Soda: A little goes a long way in helping the cookies rise and brown beautifully.
• Chocolate Chips (dairy-free if preferred): A generous handful melts into decadent gooey pockets with every bite.
• Flaky Sea Salt: Sprinkled on top, it brings out all the sweet and nutty flavors with a sophisticated finish.

How to Make Flourless Peanut Butter Oatmeal Chocolate Chip Cookies

Step 1: Prep Your Baking Station

Start by preheating your oven to 350°F (175°C) and lining a baking sheet with parchment paper. This little step guarantees your cookies won’t stick and helps with even baking. Set yourself up for success here — it’s so worth it!

Step 2: Mix the Dry Ingredients

In a small bowl, combine the rolled oats and baking soda. This ensures the baking soda gets evenly distributed throughout the cookies, helping them puff up to chewy perfection.

Step 3: Make the Peanut Butter Base

In a larger bowl, stir together the peanut butter, dark brown sugar, eggs, and vanilla extract until smooth and glossy. Mixing until creamy at this stage promises a uniform, ultra-peanutty dough that forms the heart of these Flourless Peanut Butter Oatmeal Chocolate Chip Cookies.

Step 4: Combine & Add Chocolate Chips

Pour the oat mixture into the wet ingredients, stirring just until combined. Then, fold in the chocolate chips, being careful not to overmix. This step is where all that chewy, chocolatey goodness starts coming together!

Step 5: Scoop and Shape the Cookies

Use a scoop or your hands to form 2-inch balls of dough, spacing them about 2 inches apart on your prepared baking sheet. If the dough is sticky, a cookie scoop is your best friend. Gently flatten each mound with your hand — the cookies will spread a little, but a soft press helps create that classic cookie shape.

Step 6: Bake to Perfection

Bake for 9-12 minutes, watching closely for golden brown edges. Don’t worry if the centers look a tad underdone; they’ll finish setting up as they cool, guaranteeing that dreamy chewy middle everyone loves.

Step 7: Cool the Cookies

Let the cookies rest on the baking sheet for 5 minutes — they’re fragile right out of the oven! Then transfer to a wire rack to cool completely, where they’ll firm up but retain their signature chewiness.

Step 8: Sprinkle with Sea Salt

Once your cookies are cooled, sprinkle the tops with flaky sea salt. This is the magic finishing touch that makes all the flavors pop in your Flourless Peanut Butter Oatmeal Chocolate Chip Cookies.

Step 9: Repeat and Enjoy

Continue scooping, baking, and cooling with the remaining dough. This recipe yields about 16-20 glorious cookies — perfect for sharing, gifting, or stashing in your secret treat drawer.

How to Serve Flourless Peanut Butter Oatmeal Chocolate Chip Cookies

Garnishes

A little flaky sea salt sprinkled just before serving magnifies all those rich chocolate and peanut butter flavors. If you’re feeling playful, try pressing a few extra chocolate chips into the tops as soon as the cookies come out of the oven for an even more decadent look.

Side Dishes

Cookies and milk might be the classic pairing, but these chewy treats also shine alongside a freshly brewed cup of coffee, hot cocoa, or even a scoop of vanilla ice cream for an extra-luxe dessert. They’re also perfect on a brunch platter with fresh fruit for a sweet finish!

Creative Ways to Present

Stack these Flourless Peanut Butter Oatmeal Chocolate Chip Cookies in a glass cookie jar as an irresistible countertop centerpiece, or bundle them in cellophane tied with a ribbon for gift bags. For a dinner party twist, sandwich a scoop of vanilla or chocolate ice cream between two cookies for the ultimate ice cream sandwich.

Make Ahead and Storage

Storing Leftovers

Once completely cooled, keep your cookies in an airtight container at room temperature. They’ll stay soft and chewy for up to 5 days, perfect for impromptu sweet cravings or lunchbox treats throughout the week.

Freezing

For longer-term storage, you can freeze these cookies baked or unbaked. Store baked cookies in a freezer bag for up to 2 months. For unbaked dough, portion it into balls and freeze on a tray. Once solid, transfer them to a freezer bag and bake straight from the freezer — just add an extra minute or two to the baking time.

Reheating

To recapture that just-baked warmth, pop a cookie in the microwave for about 10 seconds or reheat in a low oven for a few minutes. This little pick-me-up brings back the gooey chocolate and all those fresh flavors.

FAQs

Can I use chunky peanut butter instead of creamy?

Absolutely! Chunky peanut butter adds an extra burst of crunch and peanutty texture. Just make sure it’s natural and made with only peanuts and salt for the best results.

Are these cookies gluten-free?

Yes, as long as you use certified gluten-free oats, these Flourless Peanut Butter Oatmeal Chocolate Chip Cookies are a wonderful gluten-free option for any cookie lover.

Can I replace the eggs with a vegan substitute?

For an egg-free or vegan version, you can swap each egg for a flaxseed egg (1 tablespoon ground flaxseed mixed with 2.5 tablespoons water, set until thickened). The cookies may be a bit softer but still delicious!

How do I know when the cookies are baked perfectly?

The cookies are ready when the edges turn golden brown but the centers still look soft. Don’t worry — they’ll continue to set as they cool, leaving you with the perfect chewy texture.

Can I add mix-ins besides chocolate chips?

Certainly! Chopped nuts, dried cranberries, or even a handful of coconut flakes are fantastic in these cookies. Just be mindful not to overload the dough so your cookies hold together nicely.
