These classic oatmeal cookies with old fashioned oats are right up there as one of my favorite cookie recipes and they don’t even have chocolate in them. Imagine that!

I’ve tested and retested plenty of cookies in my day and I happened to have found the best old fashioned oats cookies. My husband says they’re even better than his previous favorite, Archway oatmeal cookies!

They’re buttery and brown sugary with a hint of cinnamon and have a delicate sweet and salty balance. The center is chewy with slightly crispy edges and all the nooks and crannies are perfect for soaking up the milk you’ll be dunking them in!

Sometimes we like to do it up a little with iced oatmeal cookies but this time we’re sticking with the tried and true classic.

Equipment you’ll need

  • My favorite measuring spoons – I love that they’re magnetic so they stay together & aren’t a mess all over my supply drawer.
  • Good baking mats  – you can use parchment paper, and I often do, but silicone baking mats help with even cooking and make clean up a breeze. Plus, it’s less wasteful.
  • My favorite baking sheets – my dad got me a similar set YEARS ago for Christmas and they’ve been my go-to set ever since.


Below is a list of the ingredients you’ll need to gather to make this recipe, why you need them, and possible substitutions. Scroll all the way down for the full recipe card with measurements.

  • Old Fashioned Oats – Don’t try and swap for Instant or quick-cooking oats for these cookies as they absorb liquids faster than old-fashioned oats and won’t deliver the same results.
  • All-Purpose Flour – Gives the cookies structure so it’s very important to measure the flour accurately so you don’t end up with dense cookies.
  • Baking Powder & Baking Soda – Both are leavening agents that prevent the cookies from falling flat.
  • Cinnamon & Nutmeg – The infusion of these warm spices give us a bit of extra soul-warming flavors, perfect for the fall!
  • Salt – We’re adding just a bit of salt to bring out the flavors and to balance out the sweetness from the sugars. Since we’re using unsalted butter, we can then control the amount we add to the dough.
  • Unsalted Butter – Melted and cooled before adding it in so that it doesn’t cook the eggs.
  • White Sugar & Brown Sugar – Both give the necessary sweetness but light brown sugar gives it a little extra molasses flavor. The darker the brown sugar, the deeper that flavor will be.
  • Large Eggs – For binding all of the ingredients together so the cookies to fall apart as you go to take a bite! Since everything else is at room temperature, it’s a good idea to bring your eggs to room temperature too. Do this about 30 minutes before baking.

This section shows you how to make this recipe, with process photos showing the steps to help you visualize it. For full instructions, including amounts and temperatures, see the recipe card below.

  1. Step One: Pulse the oats in a food processor until they’re partially ground. Not into a powder, you still want texture! Transfer them to a large mixing bowl and add the flour, baking powder, baking soda, cinnamon, nutmeg, and salt. Mix and set the dry ingredients aside.

Tips and Suggestions for making Old Fashioned Oats Cookies

  • You can use a larger cookie scoop for bigger cookies. You’ll just end up with fewer than 50 cookies. Using a medium cookie scoop for this recipe should make about 3 dozen (36-40) cookies.
  • Feel free to add in whatever mix-ins you like – raisins, chocolate chips, peanut butter chips, dried cranberries, chopped nuts, white chocolate chips, you name it.
  • Remember to line your baking sheet to help prevent too much spreading. You can also chill the dough for about 1 hour if you have the extra time.
  • If you have salted butter on hand, go ahead and use it. Just skip adding any extra salt.

How to store Old Fashioned Oats Cookies

How to store leftovers

Keep old fashioned oats cookies stored in an airtight container at room temperature. No need to refrigerate them, they’ll stay fresh for up to 5 days.

Can I freeze them?

Certainly! Since this recipe makes so many, freezing half for later is a great idea!

Store them in a freezer bag or freezer-safe container and store them in the freezer for up to 3 months. Thaw on the counter before serving.

What is the difference between old fashioned oats and quick cooking oats?

Old fashioned oats are less processed than quick-cooking oats. Quick cooking or instant oats are made to absorb water faster, therefore cooking them faster. The difference this makes in these oatmeal cookies is that the old fashioned rolled oats will give you a heartier, chewier texture. Quick oats will have less texture, but they will taste the same.

I know which I prefer, but it really is a personal preference!

Can I freeze the dough?

This oatmeal cookie dough freezes beautifully. Scoop the dough onto a parchment paper-lined cookie sheet, cover with plastic wrap, and freeze for a couple of hours. Once they’re frozen, drop the frozen balls into a freezer bag and store them in the freezer for up to 3 months.

When you’re ready to bake them, just add an extra minute of bake time straight from the freezer for a batch of cookies on demand!

Should I chill the dough?

I don’t find this to be a necessary step for making these old fashioned oats cookies, but it won’t hurt either. If you aren’t ready to bake them yet, or you want to make double sure they won’t spread too much, then go ahead and chill the dough for up to 1 hour before baking.

How to keep my cookies from drying out?

Once you’ve had your fair share of sampling and are ready to put them away for the week, make sure to keep them covered at all times so that they don’t dry out. If you find they’re getting a bit dry, place a piece of bread in the container (not directly on the cookies) to help contain the moisture.

  1. Your cookie looks awesome! I’d like to make them, but I have a person in my family that’s is allergic to butter. Do you think I could use Coconut oil? or is there something else you’d recommend that is a non-animal product?

    1. Hi Wendy =) Coconut oil can typically be swapped in for butter on a 1:1 ratio. I haven’t tried it in these cookies but I have in chocolate chip & it works out beautifully so I don’t see why it wouldn’t. Let me know how they turn out!

  2. Hi there!
    How long can we keep or store them at room temperature? Can we freeze or refrigerate? It would be great to know just in case I make loads of them! 😀

    1. Hey Kimmy,
      You can scoop the dough into balls then freeze on a cookie sheet. Once they’re frozen, drop them into a zip lock freezer bag for storage. When you’re ready to bake them, just add an extra minute to the listed bake time. I do that often when I make a lot of dough, then just make 1-2 when I get a craving 😉 As far as ones you’ve already baked, I’d say they’d stay good at room temp, in an airtight container, for about a week. Mine never last that long. =)

    I made these for Christmas and they are by far the best oatmeal cookies I have ever eaten. Thank you for sharing this fantastic recipe. I am craving them already.

  4. 5 stars
    Great recipe however I used half butter and half shortening.
    What I added to bring out that umami flavour was 1/3 cup of small shredded coconut.
