Step‑by‑Step Instructions for Easy 5-Ingredient Flourless Peanut Butter Oatmeal Cookies
Step 1: Preheat Your Oven
Begin by preheating your oven to 350°F (175°C), ensuring it reaches the right temperature for perfectly baked cookies. While the oven warms up, line a baking sheet with parchment paper to prevent sticking and make cleanup a breeze later. This simple preparation sets the stage for your delicious Easy 5-Ingredient Flourless Peanut Butter Oatmeal Cookies.
Step 2: Combine The Base Ingredients
In a large mixing bowl, combine the creamy peanut butter, oats, and your choice of honey or maple syrup. Use a sturdy spatula to blend these ingredients until well combined and smooth, creating a thick, sticky mixture. This is where the magic starts, forming the foundation of your cookies with that satisfying peanut butter flavor.
Step 3: Add Binding Agents
If you’re opting for the traditional version, beat an egg in a separate bowl until frothy, then fold it into the peanut butter mixture until fully incorporated. For a vegan twist, prepare your flax egg by mixing 1 tablespoon of ground flaxseed with 2.5 tablespoons of water and letting it sit for about 5 minutes until it thickens. Then, mix this into your batter for binding and moisture.
Step 4: Incorporate Baking Soda
Next, sprinkle the baking soda into your cookie mixture. Stir well to ensure that the baking soda is evenly distributed throughout the batter, which helps your cookies rise while baking. At this point, you may also add any optional mix-ins like dark chocolate chips or dried fruit, elevating the flavor profile of your Easy 5-Ingredient Flourless Peanut Butter Oatmeal Cookies.
Step 5: Scoop The Dough
Using a tablespoon or a cookie scoop, scoop generous portions of dough and place them onto the prepared baking sheet. Ensure they are spaced about 2 inches apart to allow for spreading during baking. The dough should look thick and slightly sticky; this ensures a chewy texture in your finished cookies.
Step 6: Bake To Perfection
Pop the baking sheet into your preheated oven and bake the cookies for 10-12 minutes. Keep an eye on them; they should have golden edges while the centers appear set but soft. Trust your instincts—your Easy 5-Ingredient Flourless Peanut Butter Oatmeal Cookies will firm up as they cool outside the oven.
Step 7: Cool Before Serving
Once baked, remove the cookies from the oven and allow them to cool on the baking sheet for about 5 minutes. This cooling time is crucial as it helps them firm up further. After that, gently transfer them to a wire rack to cool completely before indulging in the chewy delight of your homemade cookies.

Peanut Butter Oatmeal Cookies Recipe FAQs
What type of peanut butter should I use for these cookies?
Absolutely! For the best results, I recommend using natural, creamy peanut butter without added sugars or oils. This ensures a smooth and well-blended batter that holds its structure while baking.
How should I store my peanut butter oatmeal cookies?
You can store your cookies in an airtight container at room temperature for up to 7 days to maintain their chewiness. If you prefer them chilled, they can be refrigerated for up to 10 days, though make sure to let them come back to room temperature for the best flavor.
Can I freeze these cookies?
Yes, you can! To freeze, place the cookies in a single layer on a baking sheet and freeze until solid. Then, transfer them to an airtight container or zip-lock bag, where they can be stored for up to 3 months. When you’re ready to enjoy them, simply thaw in the fridge overnight or at room temperature.
What if my cookies come out too dry or crumbly?
No worries! If your cookies turn out dry, it might be due to overbaking or using too much flour. For a chewy texture, make sure to bake them just until the edges are golden and the centers look set but soft. If you find your dough crumbly before baking, try adding a splash of milk or a bit more peanut butter to adjust the consistency.
Is this recipe suitable for those with nut allergies?
While this recipe contains peanut butter, you can easily make it nut-free by substituting with sunflower seed butter or tahini instead. Both options work wonderfully while maintaining the chewy texture of these delicious cookies!
