How to Make Oatmeal Raisin & Walnut Cookies

Preheat Preheat your oven to 350°F (175°C), placing racks in the center. Line two baking sheets with parchment paper to ensure even heat and easy cookie removal.
Cream In a large bowl, beat softened unsalted butter with granulated and brown sugars on medium speed until light, fluffy, and pale in color, about 3 minutes.
Add Add eggs one at a time, beating after each until combined, then stir in vanilla extract until the mixture is smooth and homogenous, about 15–20 seconds.
Whisk In a separate bowl, whisk together all-purpose flour, baking soda, salt, and ground cinnamon until evenly blended and no clumps remain.
Combine Gradually add the dry mixture to the butter mixture on low speed, mixing until a soft, slightly sticky dough forms and no streaks of flour remain.

For the Mix-ins:

Stir Fold in chopped walnuts and plump raisins with a sturdy spatula until evenly distributed throughout the dough, ensuring each cookie will have a balanced crunch and chew.
Scoop Using a cookie scoop or tablespoon, portion dough balls onto prepared sheets, spacing them 2 inches apart for proper spreading.
Bake Bake cookies in the preheated 350°F oven for 10–12 minutes, or until edges are golden brown and centers still look slightly soft.
Cool Let cookies rest on the baking sheet for 5 minutes, then transfer to a wire rack to cool completely and set their shape.

Optional: Sprinkle flaky sea salt on warm cookies for a sweet-savory finish.

Make Ahead Options

These Oatmeal Raisin & Walnut Cookies are perfect for meal prep enthusiasts! You can prepare the cookie dough up to 24 hours in advance by following these simple steps: After mixing the dough, scoop it into balls and place them on a parchment-lined tray. Cover tightly and refrigerate. This not only helps the flavors meld but also prevents the dough from spreading too much during baking. When you’re ready to enjoy these delicious cookies, simply take the dough balls out of the refrigerator, let them sit at room temperature for about 10 minutes, then bake as directed. They’ll bake up just as delicious and fresh, saving you time on busy weeknights!

Expert Tips for Oatmeal Raisin & Walnut Cookies

Use old-fashioned oats: They provide the perfect chewy texture; avoid quick oats as they can make cookies too soft or mushy.
Toast the walnuts: Lightly toasting walnuts before mixing enhances their crunch and brings out a deeper, nuttier flavor.
Don’t overmix the dough: Stir just until ingredients combine to keep cookies tender, preventing a tough or dense texture.
Chill dough if needed: If your kitchen is warm, refrigerate dough 15–30 minutes to control spreading and maintain shape.
Watch baking time closely: Remove cookies when edges turn golden but centers remain soft for that ideal chewy-crisp balance.
Use parchment paper: It ensures even baking and makes cleanup easier, preserving your cookies’ perfect bottoms.

How to Store and Freeze Oatmeal Raisin & Walnut Cookies

Room Temperature: Store baked cookies in an airtight container at room temperature for up to 5 days to keep them fresh and chewy.

Fridge: For longer freshness, refrigeration is possible; however, this may alter the texture slightly. Cookies can last up to 10 days when stored in the fridge.

Freezer: Freeze unbaked cookie dough balls for up to 3 months. Place them on a baking sheet to freeze individually, then transfer to a resealable bag.

Reheating: When ready to enjoy, bake frozen dough straight from the freezer at 350°F (175°C) for an additional minute or two, bringing those delightful oatmeal raisin & walnut cookies back to life!

Oatmeal Raisin & Walnut Cookies Recipe FAQs

How do I know if my oats and walnuts are fresh enough to use?
Choose rolled oats that look dry and fluffy with no clumping or off smell. Walnuts should be firm, fragrant, and free of dark spots or a bitter taste, which indicates rancidity.

Can I store these cookies overnight and still have them taste fresh?
Absolutely! Store baked cookies in an airtight container at room temperature for up to 5 days. For a little extra longevity, pop them in the fridge—just be aware this may slightly change their chewy texture but keeps them good up to 10 days.

Is it possible to freeze the cookie dough or baked cookies?
Yes, and I recommend it! To freeze dough, scoop balls onto a parchment-lined tray, freeze until solid (about 1–2 hours), then transfer to a zip-top freezer bag for up to 3 months. When baking, add 1–2 minutes to the original baking time straight from the freezer. Baked cookies freeze well too—wrap tightly and thaw at room temperature for a soft, homemade taste.

What if my cookies spread too much or come out too flat?
This can happen if the dough is too warm or overmixed. To fix it, chill the dough for 15–30 minutes before baking. Also, measure flour carefully—not too little! Using old-fashioned oats instead of quick oats helps maintain structure without turning flat.

Are these cookies safe for pets or good for people with allergies?
While these homemade cookies are made with wholesome ingredients, walnuts can be a common allergen, and raisins are toxic to dogs and some pets. Always keep these treats away from your furry friends and be cautious if serving to anyone with nut allergies. I often suggest swapping walnuts for pumpkin seeds or sunflower seeds for a nut-free alternative.
