- 1 ¾ cups all-purpose flour
- 1 teaspoon baking soda
- ½ teaspoon baking powder
- ½ teaspoon salt
- 1 teaspoon ground cinnamon
Wet Ingredients
- 1 cup unsalted butter, softened
- 1 cup brown sugar
- ½ cup granulated sugar
- 2 large eggs
- 2 teaspoons vanilla extract
Mix-Ins
- 1 ½ cups chopped walnuts
- ½ cup white chocolate chips (optional)
- ½ cup raisins (optional)
Equipment Needed
- Large mixing bowl
- Medium bowl
- Electric mixer
- Cookie scoop
- Baking sheets
- Parchment paper
- Cooling rack
Preparing Your Oven
Preheat your oven to:
350°F (175°C)
Line baking sheets with parchment paper.
This prevents sticking and helps the cookies bake evenly.
Mixing the Dry Ingredients
In a medium bowl combine:
- Flour
- Oats
- Baking soda
- Baking powder
- Salt
- Cinnamon
Whisk thoroughly.
Mixing the dry ingredients first ensures even distribution throughout the cookie dough.
Set aside.
Creaming Butter and Sugars
In a large mixing bowl beat together:
- Softened butter
- Brown sugar
- Granulated sugar
Mix for approximately 3–4 minutes.
The mixture should become light and fluffy.
This step is important because it creates air pockets that help produce soft cookies.
Adding Eggs and Vanilla
Add the eggs one at a time.
Mix well after each addition.
Add vanilla extract.
Continue beating until smooth.
The batter should appear creamy and well blended.
Combining Wet and Dry Ingredients
Gradually add the dry mixture to the wet ingredients.
Mix on low speed.
Do not overmix.
Once the flour disappears, stop mixing.
Overmixing can create dense cookies.
Adding the Walnuts
Fold in the chopped walnuts using a spatula.
If desired, also add:
- White chocolate chips
- Raisins
- Dried cranberries
The walnuts provide a wonderful crunch that perfectly complements the chewy oats.
Chilling the Dough
Cover the dough and refrigerate for:
30 minutes
This step prevents excessive spreading and helps develop flavor.
If you’re short on time, you can bake immediately, but chilling produces better results.
Shaping the Cookies
Using a cookie scoop or spoon, place portions of dough onto prepared baking sheets.
Leave approximately 2 inches between each cookie.
The cookies will spread slightly during baking.
For bakery-style cookies, make the dough portions slightly larger.
Baking
Bake for:
10–12 minutes
The edges should be lightly golden.
The centers may appear slightly soft.
Do not overbake.
The cookies will continue cooking while cooling.
Cooling
Allow cookies to rest on the baking sheet for 5 minutes.
Transfer to a cooling rack.
Cooling helps the cookies set properly while maintaining a chewy center.
The Secret to Soft Cookies
Many bakers accidentally overbake oatmeal cookies.
Remember:
The cookies should look slightly underdone when removed from the oven.
As they cool, they firm up while staying wonderfully soft.
This simple trick creates bakery-quality cookies every time.
Why Oats Make These Cookies Special

They add:
- Texture
- Fiber

Old-fashioned oats are ideal because they provide a heartier bite than quick oats.
Their natural chewiness makes oatmeal cookies uniquely satisfying.

Walnuts are one of the healthiest nuts available.
They contain:
