Chewy Oatmeal Cookies

The BEST Chewy Oatmeal Cookies ever! This family recipe is a basic oatmeal cookie that can be customized with raisins, craisins, nuts, or chocolate chips.

Chewy Oatmeal Cookies

This is the 2nd Day of Christmas in my 12 Days of Christmas Series.

Two of the most ubiquitous Christmas cookies in my family – butter and oatmeal – come from my paternal grandmother, Maw Maw. For many years, these oatmeal cookies have always been my favorite (although it’s VERY close). These cookies are unlike any I’ve ever tasted – they are not your traditional chewy oatmeal cookie, although they can be made chewier by adding more oatmeal or raisins/nuts (or accidentally leaving out an ingredient – see below!) I just like them plain.  

Chewy Oatmeal Cookies

While an Oatmeal Cookie may sound boring and ordinary, there’s just something about these cookies that sets them apart. Maybe it’s the thinness, or the fact that the edges taste almost like toffee; it’s really just indescribable. It’s amazing how taste and smell can retrieve memories, perhaps even better than any of our senses, and to me, these cookies taste like Christmas.  

They are typically a crispier cookie, so sometimes I heat them for 2-5 seconds in the microwave and have them with a big glass of skim milk. This most recent time making Oatmeal Cookies, they ended up chewy and soft on their own because I forgot the powdered sugar. The cookies actually stayed chewy days later – I think this was a serendipitous discovery! I told my mom, and she said that Maw Maw always told her that the powdered sugar makes them crispy – she was right!

For some reason, we always decorate them using these colored sprinkles. Occasionally you’ll see them with red/green sprinkles, but that’s pretty rare. Who knows!

What Makes these Oatmeal Cookies Chewy?

It’s been many years since this post, and I continue to omit the powdered sugar in this recipe for a thin, chewy oatmeal cookie! Because these cookies don’t have a large amount of flour compared to the amount of butter, they are thinner which helps they stay chewy.

I’ve made these for Valentine Tea Parties using Valentine sprinkles. Shown below with Linzer Cookies (recipe coming soon!) and Dark Chocolate Covered Cherry Cookies.

Gluten Free Chewy Oatmeal Cookies

While I have not tried this myself yet, gluten free flour such as Bob’s Red Mill Gluten Free 1 to 1 Baking Flour could be substituted for the all purpose flour.

Prep Time 15 mins
Cook Time 10 mins
Total Time 25 mins
Course Dessert
Cuisine American
Servings 2 dozen or more depending on size


  • 1 cup butter (2 sticks)
  • 2 eggs
  • 1 cup dark brown sugar
  • 1 cup sugar
  • 1 teaspoon vanilla
  • 1/4 cup powdered sugar (omit for chewy cookies)
  • 1 teaspoon baking soda
  • 1/2 teaspoon salt
  • 1 teaspoon cinnamon
  • 1 1/4 cups flour
  • 3 or 4 cups old fashioned oatmeal (see note)

Optional Mix Ins and Toppings:

  • nuts, raisins, candied cherries, chocolate chips, sprinkles


  • Preheat oven to 350 degrees F.
  • Using a stand or hand-held mixer, cream the butter, eggs, and sugars until well combined. Omit powdered sugar for a chewier cookie. Add vanilla and mix until incorporated.
  • Sift together baking soda, salt, cinnamon, and flour. Add to butter mixture until completely incorporated.
  • Add 3 cups of oatmeal to the mixture. If it is too gooey to work with, add more until it can be rolled into balls. Add the nuts or raisins if using.
  • Place small balls of dough on a slightly greased cookie sheet and flatten slightly before baking. Sprinkle with decorations, if desired. Make sure to leave enough space between cookies as they spread quite a bit. If you omit the powdered sugar, leave even more space, perhaps only 6 cookies per cookie sheet.
  • Bake for 8-10 minutes. They will spread and be flat and chewy. If you use the powdered sugar, they will be flat and crispy. Adding more oatmeal and raisins/nuts will make them thicker and chewier.
  • Remove from cookie sheet to a cooling rack immediately or they will stick.


I prefer old fashioned oatmeal for this recipe.  You may use quick oats, but the cookies will be more homogenous.
