Ingredients
Dry Ingredients
- 1 ½ cups old-fashioned rolled oats
- 1 ¼ cups all-purpose flour
- ½ teaspoon baking soda
- ½ teaspoon baking powder
- ½ teaspoon salt
- 1 teaspoon ground cinnamon (optional but recommended)
Wet Ingredients
- ¾ cup unsalted butter, softened
- ¾ cup brown sugar, packed
- ½ cup granulated sugar
- 2 large eggs
- 2 teaspoons vanilla extract
Mix-Ins
- 1 ½ cups semi-sweet chocolate chips
- ½ cup chopped walnuts or pecans (optional)
Kitchen Tools You’ll Need
- Large mixing bowl
- Medium bowl
- Electric mixer or whisk
- Measuring cups and spoons
- Baking sheet
- Parchment paper
- Cookie scoop or spoon
- Cooling rack
Step-by-Step Instructions
Step 1: Prepare the Oven
Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper to prevent sticking and ensure even baking.
Step 2: Mix the Dry Ingredients
In a medium bowl, combine:
- Flour
- Oats
- Baking soda
- Baking powder
- Salt
- Cinnamon
Whisk everything together until evenly mixed. Set aside.
This step helps distribute the leavening agents evenly throughout the dough, ensuring your cookies bake uniformly.
Step 3: Cream Butter and Sugars
In a large bowl, beat the softened butter, brown sugar, and granulated sugar together until light and fluffy. This usually takes about 2–3 minutes using an electric mixer.
The brown sugar adds moisture and chewiness, while the white sugar helps create lightly crisp edges.
Step 4: Add Eggs and Vanilla
Add the eggs one at a time, mixing well after each addition. Stir in the vanilla extract.
The mixture should look smooth, creamy, and slightly fluffy.
Step 5: Combine Wet and Dry Mixtures
Gradually add the dry ingredients into the wet mixture. Stir gently until just combined.
Avoid overmixing the dough because it can make the cookies dense instead of soft and chewy.
Step 6: Fold in Chocolate Chips
Add the chocolate chips and optional nuts. Fold them evenly into the dough using a spatula or wooden spoon.
At this point, the dough will be thick and hearty thanks to the oats.
Step 7: Scoop the Dough
Using a cookie scoop or tablespoon, place rounded balls of dough onto the prepared baking sheet. Leave about 2 inches of space between each cookie.
For thicker cookies, chill the dough for 20 minutes before baking.
Step 8: Bake
Bake the cookies for 10–12 minutes, or until the edges are golden brown and the centers still look slightly soft.
Do not overbake. The cookies will continue cooking slightly as they cool on the baking sheet.
Step 9: Cool and Serve
Allow the cookies to cool on the baking tray for 5 minutes before transferring them to a wire rack.
Serve warm for gooey melted chocolate perfection, or store them for later.
Tips for the Best Oatmeal Chocolate Chip Cookies
Use Old-Fashioned Rolled Oats
Rolled oats provide the best chewy texture. Quick oats can make the cookies softer and less textured.
Don’t Overbake
Slightly underbaked centers create perfectly chewy cookies once cooled.
Chill the Dough
If your kitchen is warm or your dough feels sticky, chilling the dough helps prevent spreading.
Add Extra Flavor
Try mixing in:
- Shredded coconut
- Raisins
- Peanut butter chips
- Dark chocolate chunks
- Sea salt flakes
Storage Instructions
Room Temperature
Store cookies in an airtight container for up to 5 days.
Refrigerator
Keep refrigerated for up to 1 week for extra freshness.
Freezer
Freeze baked cookies for up to 3 months. You can also freeze cookie dough balls and bake directly from frozen by adding 1–2 extra minutes to the baking time.
Serving Suggestions

- A cold glass of milk
