There’s a very specific kind of cookie I picture when I think about oatmeal cookies, and it’s not the thick, overstuffed bakery version with everything but the kitchen sink in it.

It’s old-fashioned oatmeal cookies that get me. You know the ones, slightly crisp around the edges, soft in the middle, a little chewy, and just sitting there on a plate like it’s been around all afternoon. The kind you grab one of while you’re walking through the kitchen…and then somehow you’re back a few minutes later for another.

I didn’t grow up thinking oatmeal cookies were anything special. And If I’m being totally honest, I didn’t even really like them. They were always just the boring unwanted cookie. The one you picked when you when absolutely everything else was gone.

But somewhere along the way, I realized a really good old-fashioned oatmeal cookie doesn’t need to compete with anything, it’s great on its own. It’s not overly sweet, it doesn’t need frosting, and it definitely doesn’t need a long list of add-ins to prove a point (that basic is good).

This version leans way into that. It’s simple. Brown sugar for depth, enough butter to keep them soft, oats that actually taste like something, and just a little cinnamon to round it out without turning it into a spice cookie. They’re easy, reliable, just plain good.

Ingredient Notes

• Old-fashioned oats give the cookies the best texture. They hold their shape and give that classic chew. Quick oats will work, but the cookies will be softer and a little less textured. If you can find the, Bob’s Red Mill makes an extra thick oat, which is the bomb in oatmeal cookies.
• I usually use dark brown sugar. It gives a deeper, almost caramel-like flavor that makes these feel a little more like the cookies you remember.
• Unsalted, room temperature butter is the best option. If you use salted butter, you may want to pull back just slightly on the added salt.
• You can use up to 1 teaspoon of ground cinnamon (if you’re a big cinnamon fan) in these cookies, but leep it light. This isn’t a spice cookie, just a little something in the background.

Step-By-Step Instructions

1. Preheat your oven to 350°F and line a few baking sheets with parchment paper.
2. In a large bowl, cream the butter, brown sugar, and granulated sugar together for 1–2 minutes until smooth and slightly fluffy.
3. Add the egg and vanilla extract and mix for another minute, just until combined.
4. In a separate bowl, whisk together the flour, baking soda, salt, and cinnamon. Add the dry ingredients to the wet ingredients and mix until just combined.
5. Stir in the oats and mix until they’re evenly incorporated.
6. Scoop the dough into about 2 tablespoon portions and place on your prepared baking sheets, leaving a little space between each (these cookies do spread a tad).
7. Bake for 9–11 minutes, until the edges are lightly golden and the centers still look soft.
8. Let them sit on the baking sheet for a few minutes before moving them to cool completely.

Recipe Tips & Notes

• The dough will be soft, that’s normal and what we’re going for. The oats will absorb some moisture as it sits.
• Use a cookie scoop to scoop the dough. This keeps the cookies uniform in size, so they bake evenly and hold a nice, round shape.
• If you like a softer cookie, pull them out when the centers still look slightly underdone. They’ll finish setting as they cool.
• The cookies will be very soft and fragile when they first come out of the oven (this is totally normal and what we’re going for). After reshaping them, let them sit on the baking sheet for 5-10 minutes to set up before moving them to cool completely.
• For flatter cookies, gently press the dough balls down before baking. It will help them spread even more.

Storage & Reheating

Store leftover cookies in an airtight container at room temperature for 3-4 days. You can also freeze the dough or baked cookies for up to 3 months. If freezing the dough, scoop it first so it’s ready to bake straight from the freezer. Then just add a minute or two to the bake time.
