Delicious and flavorful Oatmeal Pecan Cookies — crisp on the edges and chewy in the center!

Oatmeal Pecan Cookies are a classic that everyone loves! If you aren’t sure about nuts in your cookies, this is the perfect recipe to start with! Or click if you’d like to stick with Oatmeal Chocolate Chip Cookies (no nuts) or these Coconut Oatmeal Cookies.

Oatmeal Pecan Cookies

My favorite cookie ever is an oatmeal chocolate chip (does that make me boring?!). I have so many different oatmeal cookie variations on this site — some with caramel, some with coconut, some plain, and some with lots of chocolate. So, it was definitely necessary to add some nuts to an oatmeal cookie and share that recipe as well!

These cookies have crispy and crunchy sugary edges, a soft slightly underbaked center, plenty of melted chocolate throughout, and overall, plenty of chewiness. We’re totally obsessed with them!

Beating the butter and sugars until creamy, adding egg and vanilla and mixing again, combining dry ingredients with wet ingredients, and adding chopped nuts and chocolate.

How to make oat flour

To add an extra oat-y flavor to these cookies, we use oat flour. No need to run out and buy a special flour for these cookies, though — if you have oats, you can have oat flour in minutes.

  1. Add old-fashioned oats to a food processor or small blender jar.
  2. Pulse the oats until they are ground into a powder-like consistency that resembles flour.
  3. Stir the oats around to be sure that all the oats have been finely ground and there aren’t any whole oats left (this will affect the texture and liquid absorption of these oatmeal pecan cookies). 

Quick Tip

Make sure to fill the ¼-cup measurement of oat flour to the very top. Then level off the top by scraping the backside of a table knife across the top.

Dough ready to chill and dough rolled into large round balls.

Using the right ingredients

It’s important to use the right ingredients in this recipe to yield the best results.

  • Margarine doesn’t substitute for real unsalted butter, a large egg is essential, and don’t use any other kinds of oats besides old-fashioned oats!
  • The oats are particularly important because old-fashioned oats are what give these cookies such a great texture. When you use quick oats, they act like flour, making the cookies much drier and cake-like. 
  • Good-quality chocolate chips, or even chopping a high-quality chocolate bar, really heighten the flavor and give these cookies something special! I prefer Ghirardelli® or Guittard® chocolate chips for these cookies. For us, there’s nothing better than milk chocolate chips in an oatmeal cookie, but you can use semi-sweet or dark chocolate if you prefer.

Oatmeal chocolate chip pecan cookies split in half to reveal the gooey chocolate center.

  • It’s important to have room-temperature butter for this recipe. Allow the butter to come to room temperature on its own for the best results. Do not melt the butter or these cookies will spread way too much!
  • Thoroughly cream the butter and brown sugar. This helps with the cookie’s structure.
  • When measuring dry ingredients, spoon and level the measurements or weigh them for accurate measurements. If you scoop a measuring cup into a bag of flour you will pack in too much flour which will create cake-like cookies that don’t spread.
  • Chill the cookies. Chilling matters because the fats need to re-solidify and the oats need time to absorb the liquid in this recipe. If you bake the dough immediately, the cookies will spread and become thin, hard, and crispy. The longer the fat stays solid, the less the cookies will spread.
  • And then chill again. The dough is chilled again after forming the dough balls because the heat from the hands warms up that dough. We want the dough balls as cold as possible when going into the oven. 
  • Watch the bake time! Oatmeal Pecan Cookies go from soft, chewy, and delicious to overall crispy and blah in the blink of an eye. I pull them out of the oven even when they look a little gooey in the center because they firm up more when they set up. That makes them super soft and chewy. As soon as the edges are browned, these cookies are most likely finished baking!
The finished dessert, full of delicious and complementary flavors, ready to be enjoyed right out of the oven.

Oatmeal Pecan Cookies

Delicious and flavorful Oatmeal Pecan Cookies -- crisp on the edges and chewy in the center!
Prep Time: 15 minutes
Cook Time: 10 minutes
Total Time: 25 minutes
Servings: 20 cookies

Ingredients  

  • ยฝ cup (8 tablespoons/ 113g) unsalted butter at room temperature, not melted
  • ยฝ cup (110g) dark brown sugar packed
  • ยฝ cup (100g) white sugar
  • 1 large egg
  • 2 teaspoons vanilla extract
  • ยฝ cup + 3 tablespoons (86g) white flour (when you measure, make sure to spoon and level)
  • ยฝ tablespoon cornstarch
  • ยผ cup (25g) oat flour (See Note 1)
  • ยฝ teaspoon baking soda
  • ยฝ teaspoon fine sea salt
  • โ…› teaspoon nutmeg
  • ยฝ teaspoon ground cinnamon
  • 1 ยฝ cup (147g) old-fashioned oats (not quick oats)
  • 1 cup (180g) milk chocolate chips plus more for adding to the tops of the cookies
  • โ…“ cup (40g) chopped pecans

Instructions 

  • BUTTER PREP: Make sure the butter is at room temperature and not melted. Line a large sheet pan with parchment paper or a silicone liner (without one, the bottoms tend to burn).
  • WET INGREDIENTS: Cream together the butter, brown and white sugar until light and creamy, at least 3 minutes. Beat in the egg and vanilla.
  • DRY INGREDIENTS: In another bowl, add the flour and cornstarch. To make oat flour, blend regular oats in a blender or food processor until they resemble flour. Measure to get ยผ cup and add that in. Add in the baking soda, fine sea salt, nutmeg, cinnamon, and old-fashioned oats.
  • COMBINE WET AND DRY: Add the dry to the wet and mix until just combined. Stir in the chocolate chips.ย Coarsely chop the pecans and add them in.
  • CHILL DOUGH: Stir all the ingredients together, cover tightly and chill for at least an hour. These cookies don't bake well without being chilled.
  • PREHEAT OVEN: Preheat the oven to 350 degrees F.ย Scoop out balls of dough (if you have a food scale, make cookie balls about 1.8 ounces in size or about 2ยฝ tablespoons in size). Roll into even-sized balls.
  • CHILL AGAIN: Place balls of dough (no more than 8 cookies at a time; these cookies spread a lot) on the cookie sheet. Return the tray of cookies to the fridge for 10 minutes.
  • BAKE: Bake for 10-15 minutes or until lightly browned at the edges (even if the center looks a little underdone -- cookies continue to bake after being pulled out of the oven). These cookies set up and become extremely delicious and chewy if they're slightly underbaked; they firm up more as they cool. (Err on the side of slightly underbaking for soft, chewy, and tender cookies!)
  • MAKE 'EM PRETTY: Press some extra chocolate chips onto the tops of the cookies if desired. If desired, add a sprinkle of sea salt to the cookies. Cookies are best enjoyed within 2-3 days.

    Chelsea – can I just tell you how happy I am right now? I just took a bite of these spectacular cookies. I have to say I am absolutely blown away. The texture is fantastic and the rich buttery flavor mixed with the carmel-y taste of brown sugar is absolutely to die for!! I sprinkled mine with some fleur del sel and my taste buds are doing a happy dance. Thank you for creating such a delicious cookie recipe for all of us!!!

    1. chelseamessyapron says:

      Oh my gosh you made my day!! I’m sooo happy you enjoyed these!! They are some of my faves too! Thanks Carol! ๐Ÿ™‚

  2. Rita Stafford says:

    These sound delicious!! You talked about sending these cookies in a mailing cookie exchange – what would be the best way to package and ship these cookies so that they arrive fresh and unbroken?

    1. chelseamessyapron says:

      Yes!! Cookie exchanges are the best! If you line the postage box with bubble wrap before placing the container in it that should be enough to keep them in great shape! ๐Ÿ™‚

  3. Destiny says:

    Regarding that oat flour, when you say “regular oats”, are you referring to quick oats, or can old fashioned oats be used here as well?

    1. chelseamessyapron says:

      Either one works ๐Ÿ™‚

  4. Kim says:

    Anything special for high altitude adjustments

    1. chelseamessyapron says:

      I’m sorry Kim, I don’t have any experience with high altitude baking so I’m not sure on these. Wish I could be of more help.

  5. Isabelle says:

    Do you use an electric whisk to mix the dry into the wet? Or do you just use a spatula? Planning to make these!

    1. chelseamessyapron says:

      Just a wooden spoon ๐Ÿ™‚ Spatula would work as well!

  6. judy says:

    why unsalted butter, can’t I just cut back on the salt?j

    1. chelseamessyapron says:

      Sure! ๐Ÿ™‚ I just like to control the amount of salt more precisely so I generally use unsalted butter and add additional salt to my preference, but salted would work great, just leave out the additional salt or add in less.

  7. Janet says:

    Just checking – is that a total of 1 stick of butter OR 1 stick of butter + 1/2 cup? Thanks!

    1. chelseamessyapron says:

      Yes just 1 stick of butter (or 1/2 cup TOTAL!) Thanks for asking!!

    I can tell right now, the hard part for me is going to be waiting for the dough to chill! I also love Oatmeal Chocolate Chip cookies and I am excited to try yours with the cornstarch and oat flour. Love the little shape of the dough you make too! Can hardly wait to try these.

  9. Ashley says:

    Oh yum! I loveee pecans in cookies! These look fantastic!

  10. Roxana says:

    Mmmm I love pecans and chocolate together, I will definitely be incorporating this recipe into my holiday cookie baking!

    1. Wade says:

      I made these with Butterscotch chips instead of Chocolate. They went so fast I had to make another batch!
