These are the best oatmeal cookies, with rich buttery flavor, a hint of cinnamon, and lots of chewy oatmeal texture.

They’re not fancy. They’re not even very pretty. They’re just basic drop cookies filled with oats and a hint of cinnamon. Dessert possibly couldn’t get any less sophisticated.

BUT, sometimes simple is best. And these chewy oatmeal cookies really are the best. They’ve got a great chewy texture, delicious buttery-brown sugar flavor, and they’re so nostalgic. I dare you to stop at just one!

How to make these chewy oatmeal cookies

Like most drop cookies, these simple oatmeal cookies are made using the creaming method:

  1. “Cream” butter and sugars. Beat with an electric mixer and paddle attachment (if you have one), until mixture is light and fluffy. Scrape down bowl at least once.
  2. Add eggs and vanilla. Mix after each addition.
  3. Add dry ingredients. Add all at once and mix until almost combined.
  4. Add oats and mix-ins. Mix until just incorporated.
  5. Scoop. Use a medium or large cookie scoop to portion dough and arrange a few inches apart on sheet pans lined with parchment paper.
  6. Bake. Bake in an oven preheat to 350°F for 8-10 minutes for smaller cookies, 10-12 minutes for larger cookies.

Tips for baking the best cookies

  • Butter should be soft enough that a pressed finger will leave an indent, but not soft enough that your finger can press all the way through. If it’s shiny or melty at all, the butter is too warm and your cookies may spread.
  • You can use either salted or unsalted butter in these cookies, but I love the additional flavor that comes from using salted butter.
  • Be sure to measure flour correctly! All of my recipes are tested using the spoon and level method (more info through that link).
  • These pre-cut parchment sheets are perfect for cookie baking.
  • For show-stopping cookies like you see in this post, I like to make them big and use a large cookie scoop (3 tablespoon). More traditional sized cookies can be shaped with a medium cookie scoop (1½ tablespoon).
  • If cookies come out slightly misshapen, use a spatula to press them back into a circle right after they come out of the oven. See more of my tips for how to bake pretty cookies.
  • While completely optional, I love to sprinkle baked cookies with coarse or flaky salt for a bit of flair and additional sweet and salty flavor.
  • Cookie dough freezes really well. I like to keep a stash in the freezer for fresh-baked cookies on demand.
  • These cookies will keep at room temperature for about a week, but are best within a few days of baking.
