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  

  • ½ cup (8 tablespoons/ 113g) unsalted butter at room temperature, not melted
  • ½ cup (110g) dark brown sugar packed
  • ½ cup (100g) white sugar
  • 1 large egg
  • 2 teaspoons vanilla extract
  • ½ cup + 3 tablespoons (86g) white flour (when you measure, make sure to spoon and level)
  • ½ tablespoon cornstarch
  • ¼ cup (25g) oat flour (See Note 1)
  • ½ teaspoon baking soda
  • ½ teaspoon fine sea salt
  • teaspoon nutmeg
  • ½ teaspoon ground cinnamon
  • 1 ½ cup (147g) old-fashioned oats (not quick oats)
  • 1 cup (180g) milk chocolate chips plus more for adding to the tops of the cookies
  • 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 ¼ 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. 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. Scoop out balls of dough (if you have a food scale, make cookie balls about 1.8 ounces in size or about 2½ 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.

    Omg so I came across your recipe and I had to try it. I had bariatric surgery this last may and wanted to try and make a “healthier” cookie…. so I substituted some things and made a protein cookie with basically everything you did… an WOW!! Delicious thanks for sharing!!!

    1. Chelsea Lords says:

      What a great idea to make it into a protein cookie! Thanks for the comment Emily!

    Best cookies I’ve ever made! Family and friends lOVE them! Thank you for the recipe

    1. Chelsea Lords says:

      Yay!! Love hearing that! Thank you Mayda 🙂

  6. Sue says:

    These sound so good. I don’t have a blender/processor to make oat flour. Will the recipe work without the oat flour? Should I just use extra AP flour in place of the oat flour? Thanks

  7. Kat says:

    Hello
    Can the cornstarch be omitted from the recipe? Thanks.

  8. jane says:

    I want to freeze these, should I roll them into balls then freeze? also when its time to bake do I just put them straight in the oven while frozen?

    1. Chelsea Lords says:

      Yes that’s what I would do! 🙂 And bake then a couple minutes extra from frozen

  9. Seg says:

    Hi,

    I’m planning on freezing the dough so I can bake these at a later date. How would you recommend cooking them after? Should I defrost them before baking?

    1. Chelsea Lords says:

      Hey! I love freezing these cookies! I just pull them straight out of the freezer and put them in the oven, they typically just bake for 2-3 more minutes than the not frozen ones and the flavor is just as good! 🙂

  10. Hannah Wilding says:

    Hi Chelsea! Would these cookies still work as well if I chilled them in the fridge overnight and baked them the next day? Does it affect the baking time? And should I take the dough out a couple of hours before baking them? Thanks!

    1. Chelsea Lords says:

      Hey Hannah! They typically end up much puffier/thicker with an overnight chill (they don’t spread much). I think if they were taken out a few hours before, it could also mess up with consistency a bit. I’d just set them out for 10-15 minutes and flatten the dough as much as possible before baking.
