I love oatmeal cookies – they’re my favorite! I was craving some, so I decided to make a batch and add some festive decorating. These are super easy to whip up, and the texture is chewy and soft and mmmmmm.
This recipe is straightforward – no chilling the dough, no complicated steps. Just mix, scoop, bake, and decorate if you’re feeling fancy. I made a batch of these in under an hour, and they almost disappeared before I could even finish filming and taking photos.

Why This Recipe Works
I’ve tried a lot of oatmeal cookie recipes over the years, and there’s something about a classic, versatile recipe that just works. This one is delicious on its own, but the real beauty is that you can customize it however you want, chocolate chips, dried fruit, spices, you name it.
This recipe hits the basics right – the mix of brown and granulated sugar gives you that chewy texture without being cakey. The cinnamon and nutmeg add just enough warmth without turning them into spice cookies. And I used quick oats because I like a smoother texture – rolled oats work too if you want more texture and chew.
The trick is not overbaking them. Pull them out when the edges look golden but the centers still seem a little soft or puffy. They’ll finish cooking on the pan while they cool, and you’ll get soft, chewy cookies instead of hard little discs.
Ingredients You’ll Need
You’ll need basic baking staples for these – nothing fancy or hard to find. The base is butter, sugars (both brown and granulated for the right texture), flour, and quick oats. I add warm spices like cinnamon and nutmeg to give them that cozy holiday flavor.
A few notes on ingredients:
Quick oats vs. rolled oats: I use quick oats for a smoother, more uniform texture. If you prefer a chewier cookie with more visible oat pieces, you can swap in old-fashioned rolled oats using the same measurement (1½ cups).
Sea salt: This is my preference because you get these nice little salty bites that balance the sweetness. Regular table salt works fine too.
Butter: Make sure it’s softened to room temperature – not melted, not cold. It should be soft enough to press your finger into easily. This helps it cream properly with the sugars.
Decorating: The white chocolate drizzle and sprinkles are completely optional, but they make these look festive. I used candy melts because they set up quickly and don’t require tempering.

How to Make Oatmeal Cookies
Step 1: Prep your oven and baking sheet
Preheat your oven to 375°F and line a baking sheet with parchment paper. Don’t skip the parchment – it makes cleanup easier and helps prevent the bottoms from browning too quickly.
Step 2: Cream the butter and sugars
In a large bowl, cream together the softened butter, granulated sugar, and brown sugar until the mixture is light and fluffy. This usually takes 2-3 minutes with a hand mixer or stand mixer. Make sure your butter is actually softened – not melted, not cold, but room temperature and soft to the touch.
Step 3: Add the wet ingredients
Add your egg and vanilla extract, mixing until everything is well combined. I’m not super precise with vanilla – in the video you’ll see me just fill a tablespoon about halfway (roughly 1.5 teaspoons). Use 1-2 teaspoons depending on how much you like vanilla flavor. More is better in my opinion.
Step 4: Mix in the dry ingredients
In a separate bowl, whisk together the flour, baking powder, salt, cinnamon, and nutmeg. Add this to your butter mixture and mix until just combined. Don’t overmix – you just want the flour incorporated without any dry streaks.
Step 5: Stir in the oats
Stir in the quick oats until they’re evenly distributed throughout the dough. I actually use the hand mixer for the first bit to get them started, then finish folding in the last of the oats by hand with a spatula. The dough will be thick and slightly sticky.
Step 6: Scoop and bake
Scoop the dough onto your prepared baking sheet, spacing cookies about 2 inches apart. For more uniform shapes, roll each scoop into a ball with your hands, then gently flatten with your palm or the bottom of a glass. The cookies will spread slightly as they bake, but flattening them first gives you more control over the final shape.
Bake for 8-10 minutes. Watch them carefully – you want the edges and bottom to be lightly golden, but the centers should still look slightly underdone. They might even look a little puffy or soft in the middle. That’s exactly what you want.
Step 7: Cool properly
Let the cookies cool on the baking sheet for 5 minutes before transferring them to a wire rack. This cooling time is important – it lets them finish setting without overbaking.
Decorating Your Cookies
Once your cookies are completely cooled, you can dress them up for the holidays. I melted white candy melts and drizzled them over the cookies using a piping bag, then added Christmas sprinkles while the chocolate was still wet.
Tips and Substitutions
About the salt: I use sea salt because it creates these little bursts of salty flavor throughout the cookie that balance out the sweetness. If you only have table salt, that works too. Some recipes call for salted butter – if that’s what you’re using, reduce the added salt to ¼ teaspoon.
Leavening agents: You can use ½ teaspoon baking powder + ¼ teaspoon baking soda if you have both on hand. I only had baking powder available when I made these, so I used 1 teaspoon total and they turned out perfectly soft and chewy.
Make them your own: These cookies are easy to customize. Add ½ cup of chocolate chips, dried cranberries, or chopped nuts to the dough if you want. You can also swap the cinnamon and nutmeg for other warm spices like cardamom or ginger. Really, whatever you have on hand!
Storage: Keep these in an airtight container at room temperature for up to 5 days. If you decorated them with candy melts, make sure they’re completely set before stacking them, or layer parchment paper between them.
