Sometimes baking crushes my soul. There’s a very specific kind of disappointment that comes with baking cookies that spread into thin little pancakes. You mix them up thinking they’re going to be soft and hearty, and instead…they turn out thin and flat. Still edible, sure. But not at all what you had in mind (welcome to my life, haha).

These thick and chewy oatmeal cookies came out of me trying to fix that.

I wanted something that actually holds its shape, stays soft in the center, and still has those crispy edges. The kind of cookie that feels like you meant to make it that way, not like you were just hoping for the best. And these do exactly that.

Why You’ll Love These Thick and Chewy Cookies

These cookies are almost impossible to mess up. They turn out thick, chewy, and just structured enough without being dense or, as I like to say, “hockey puck style”. The oats give them that classic, hearty texture and chew, while the brown sugar keeps them soft and rich.

There’s no chilling required and the dough comes together with ingredients you already have (I promise). And most importantly, they bake up thick every time without you having to cross your fingers and hope.

Ingredient Notes

• Old-fashioned oats give the best texture here. They hold their shape and give the cookies that classic chew. Quick oats will work too, but the cookies will be softer and a little less textured.
• Light or dark brown sugar will both work for these cookies. I usually use dark brown sugar, since it’s doing most of the heavy lifting for moisture and chew. Plus it adds a slightly deeper flavor, which I love in an oatmeal cookie.
• Unsalted, room temperature butter is the best option for these guys. If you use salted butter, you may want to pull back just slightly on the added salt, so the cookies aren’t too salty.
• You can use up to 1 teaspoon of ground cinnamon (if you’re a big cinnamon fan) in these cookies, but I try to keep it light. This isn’t a spice cookie, we just want a little something in the background.

Step-By-Step Instructions

1. Preheat your oven to 350°F and line baking sheets with parchment paper.
2. In a large bowl, cream the butter, brown sugar, and granulated sugar together with an electric mixer on medium speed for 1–2 minutes, until smooth and slightly fluffy.
3. Add the egg and vanilla extract and mix until just combined.
4. In a separate bowl, whisk together the flour, baking soda, salt, and cinnamon.
5. Add the dry ingredients to the wet ingredients and mix until just combined.
6. Using a rubber spatula or wooden spoon, fold in the oats until evenly incorporated.
7. Using a 2 tablespoon cookie scoop, drop the dough onto the prepared baking sheets, spacing them a couple of inches apart.
8. Bake for 9–11 minutes, until the edges are lightly golden and the centers still look soft.
9. Let the cookies cool on the pan for about 5 minutes before transferring them to a wire rack to cool completely.

Recipe Tips & Notes

• The dough will be slightly firm, and that’s exactly what you want. The oats will absorb some moisture as it sits, which helps the cookies bake up even thicker.
• Use a (2 tablespoon) cookie scoop if you have one. It keeps everything uniform, which helps the cookies bake evenly and hold their shape.
• If you like a softer cookie, pull them out when the centers still look slightly underdone. They’ll finish setting as they cool.
• If you prefer a flatter cookie, lightly press the dough balls down before baking. It’ll help them spread out just a little bit more.

Storage Recommendations

Store the baked cookies in an airtight container at room temperature for 3–4 days. For longer storage, freeze the baked and cooled cookies for up to 3 months.

To freeze, scoop the dough into balls and freeze on a baking sheet until solid, then transfer to a freezer bag. Bake straight from frozen, adding 1–2 minutes to the baking time.
