Find the full printable recipe instructions with measurements below.

  • Old-Fashioned Oats (or “Rolled Oats”): I like to use old-fashioned oats in this recipe. When using them in baking, the oats remain whole in size, making the finished texture a little more chewy.
  • Butter: The creamy fat is an important element needed to achieve the perfect cookie.
  • Sugar: Granulated sugar gives sweetness but the brown sugar really makes the flavor shine in these cookies.
  • Baking staples: All-purpose flour, egg, vanilla, baking powder, baking soda, and salt.
  • Mix-Ins: Add a cup of chocolate chips, butterscotch chips, or raisins if desired.


While the classic version is most definitely delicious, it’s super easy to fold your favorite mix-ins into the dough. Chocolate chips, raisins, M&M’s, butterscotch chips, nuts, or white chocolate chips are just a few ideas.

My kids especially love it when we make oatmeal chocolate chip cookies or oatmeal M&M cookies because you guessed it…chocolate! However, my personal favorite is these chewy oatmeal butterscotch cookies. So delicious!

How to Make Simple Oatmeal Cookies

Made in just one bowl in 20 minutes, this will be the most easy oatmeal cookie recipe you will ever make! Oatmeal cookies are a type of cookie that includes oats as a primary ingredient. They are a popular and classic cookie choice known for their chewy texture and delicious flavor.

Showing how to make oatmeal cookies in a 4 step collage.
  1. Make dough. In a large mixing bowl, cream together butter and sugars. Use an electric mixer with a paddle attachment or a hand mixer. Then add eggs and vanilla. Stir until combined.
  2. Whisk dry ingredients. Add in the flour, salt, baking soda, baking powder, and cinnamon (if desired). Stir just until combined, then mix in the oats.
  3. Scoop. Scoop cookie dough balls onto the baking sheet or silicone baking mats using a medium cookie scoop.
  4. Bake. Bake at 350°F until edges are just light golden brown, about 8 minutes. Allow to rest for about 2 minutes on a baking sheet, then transfer to a cooling wire rack.

Baking Tip

When you take your oatmeal cookies out of the oven, the centers should look a little underdone. The cookies will continue baking on the sheet. For a softer cookie, take them out a little early. And for a crispier version, bake a little longer.

How to Avoid Flat Oatmeal Cookies

These do flatten out a little when baked, however, the texture and consistency are spot on. They are soft and chewy and the edges are perfectly crispy. If your oatmeal cookies have flattened out way too much, it could be one of the main mistakes below:

  • More flour. Your dough needs more flour. If the dough is too wet, you’ll end up with flat and greasy cookies that are too hard.
  • Butter tip! Too much butter was used, or the butter was too warm. Both create a flat and greasy cookie.
  • Missed baking soda. You forgot baking soda. This baking agent helps give the oatmeal cookies some height.

Chill Your Dough

If making multiple batches, chill the remaining dough in the fridge until ready to use. This helps ensure that the butter in the dough doesn’t get too warm, especially if left out near the hot oven. Also, be sure to use a separate baking sheet for your next batch. Allow the baking sheet to cool before using again.

Recipe FAQs

What kind of oats do you use for cookies?

Old-Fashioned Oats (or “Rolled Oats”): Old-fashioned oats are whole rolled oats that have been steamed and flattened. When using them in baking, the oats remain whole in size, making the finished texture a little more chewy.

That’s why I like to use old-fashioned oats when making chewy oatmeal cookies. Plus I love how you can still see the whole oatmeal pieces once the cookies are cooked.

Can you use quick oats in these cookies?

Yes, you can, although I prefer old-fashioned. Quick oats are essentially old-fashioned oats that have been roughly chopped. When baking with quick oats, your cookies will have a finer consistency and will often cook faster. Once baked, the texture will look a little less “bumpy”.

Can I use salted butter?

Yes you can, I just prefer to control the amount of salt I add. If you’re using salted butter, just take away 1/4 teaspoon.

Are oatmeal cookies healthy?

Yes and a no. While oatmeal cookies are on the healthier side using whole-grain oats and reducing the sugar content they are still a cookie with ingredients that contain fat in them. It is always a great alternative to cookies that are on the lighter side compared to other cookies like sugar cookies.

What can I add to oatmeal cookies for more flavor?

You can add a variety of ingredients to oatmeal cookies for extra flavor! Try these simple oatmeal cookies with raisins, chocolate chips, nuts, dried fruits, coconut flakes, and spices like cinnamon or nutmeg for all the great variations. The variations are endless!

5 star review

“A perfect, simple, easy oatmeal cookie! Made half with and half without raisins. I thank you, and my husband thanks you.”


Freezer Instructions

I prefer to freeze the dough versus the whole baked cookies so that the cookies taste more fresh. Simply scoop out the dough with a medium cookie scoop and place on a prepared baking sheet. You are going to flash-freeze the dough for about 30 minutes, or until the dough has hardened.

Then place the dough balls in a zip-top bag or airtight container and store them in the freezer for up to 3 months. When ready to enjoy, place on a baking sheet and let thaw while the oven warms up. The cookies may need to bake for a few minutes longer since the dough was hard and frozen.

Miss the frosting? Turn these cookies into oatmeal cream pies by adding marshmallow frosting in the middle. Or spread powdered sugar icing on top to make delicious iced oatmeal cookies.
