Oat Flour Cookies

Oatmeal cookies

We all seem to be comfort baking—still. And I don’t think there’s anything better to comfort bake than cookies! I came up with this recipe because I wanted to extend the precious flour that I have—so these cookies are half homemade oat flour, half good ‘ole all purpose flour! (You could also use wheat flour for half, or all of the flour!)

But back to these cookies—you really need to make these cookies because they are so easy and so delicious. And they passed the ultimate test: I shared these cookies with tons of folks, and people called me the next day hungry for more! Don’t worry—these aren’t your typical, boring “oatmeal cookies.” Yes—these cookies use oats, and lots of them. But they are chock full of other delicious stuff: chocolate chips, dried cranberries and pecans. PLUS, we made oat flour from the oats! Yes, we milled our own oat flour. It’s easier than ya think: just put rolled oats in a food processor and whizz away!

And because these cookies are easy, yummy (and wholesome!), I knew they’d be perfect for my first live Instagram bake-along, AND the first episode of my new IGTV and YouTube series: In the Kitchen with Vallery! And if you haven’t subscribed on YouTube yet, go on and click HERE to subscribe!

So, here’s the recipe. The dough will need to chill at least an hour, but it’s even better if you can chill it overnight. The cookies will spread a little, but have crispy browned edges and chewy centers.

Oat Flour Cookies Recipe

Makes 2 dozen (24)

Oat Flour Cookies Ingredients

1 cup rolled oats
1 cup all purpose flour (can sub with wheat flour)
1 tablespoon corn starch
1 teaspoon baking powder
1 teaspoon baking soda
1 teaspoon ground cinnamon (optional)
1/4 teaspoon salt
1 and 1/2 sticks (3/4 cup) unsalted or salted butter (if using salted butter, eliminate salt in recipe)
3/4 cup packed brown sugar (you can use either light or dark)
1/4 cup granulated sugar
1 large egg
1 teaspoon vanilla (optional)
3/4 cup white, milk or semi-sweet chocolate chips or chunks (use whatever chocolate you’d like!)
3/4 cup dried cranberries (optional, can also sub with golden raisins, raisins, dried cherries)
1/2 cup chopped pecans (optional, can sub with walnuts, pistachios, macadamia nuts)

Oat Flour Cookies Method

  1. Make oat flour! Add the rolled oats to a food processor and process until finely ground. Do not use instant oatmeal or steel cut oats—only rolled oats. If you don’t have a food processor, you can skip this part and just use the rolled oats.

  2. Plump the dried cranberries. This will make the dried cranberries nice and soft. Place the dried cranberries (or raisins, etc) in a small bowl. Pour boiling water on top. Set aside while prepare the rest of the cookie dough.

  3. Place the oat flour, all purpose flour, corn starch, baking powder, baking soda, cinnamon, and salt in a medium bowl. Use a fork or whisk to stir until combined.

  4. Place the butter, brown sugar and granulated sugar in a large bowl. Cream on medium until light and fluffy, about two minutes. Add the egg and vanilla and cream until combined.

  5. Add the flour mixture and mix until just combined. It’s important not to over mix here.

  6. Drain the cranberries. Add to the cookie dough. Add the chocolate and nuts to the cookie dough and stir until combined.

  7. Cover the dough and refrigerate for at least an hour—and up to two days. (I like resting this dough overnight.)

  8. When ready to bake, preheat the oven to 350 F. Line a baking sheet with parchment paper or a silplat. Scoop the cookie dough into equal sized balls and place on the cookie sheet two inches apart. Freeze for at least 20 minutes. (This is crucial to getting the right texture for the cookies.)

  9. Remove from freezer and transfer straight to the oven. Bake until browned around the edges and set in the middle, 10-14 minutes.

  10. Remove the cookies from the oven and allow to cool on the pan on a cooling rack. You can enjoy these warm, or allow to cool to room temperature and then transfer to a closed container at room temperature for up to four days.

    Great. Thanks.
    Question: step 5: must hand mix, or electric mixer is okay? Thanks!

    • Vallery Lomas SAYS | June 7, 2020

      You can use whatever mixer you like! Just be sure you use it on low during that step.

  • Aimee U. SAYS | June 5, 2020

    Just wondering if you’ve tried this with all Oat Flour? I cannot eat any wheat due to an allergy…

  • Carolie SAYS | June 5, 2020

    How many cookies should this make?

    • Vallery Lomas SAYS | June 7, 2020

      Yield has been updated to 24. 🙂

  • Jane SAYS | June 5, 2020

    I hate to use all that butter. I’ve been subbing yogurt and getting good results. Any thoughts?

    • Vallery Lomas SAYS | June 7, 2020

      OH interesting! I’m not sure. I haven’t tried subbing butter for yogurt in cookies.

  • Maureen SAYS | June 5, 2020

    They look great. Can they be made with just the oat flour? I have Celiac disease and cannot have wheat.

    • Vallery Lomas SAYS | June 7, 2020

      I’m not sure. I’m sure they’ll come together but oat flour always makes stuff less risen.

  • Lindsay Grimes Freedman SAYS | June 5, 2020

    I am currently eating these and they are HEAVENLY!! So what if it’s 8:30 in the morning 😂 Highly recommend making these!! Thanks so much for such a delicious recipe Vallary!

    • Vallery Lomas SAYS | June 7, 2020

      Yay!! 🙂 And I agree that it’s A-OK to eat oat cookies for breakfast because it’s practically oatmeal!!

  • Susan McLaughlin SAYS | June 5, 2020

    Want to make vegan with flaxseed egg. Vegan butter. I love using oat flour and cranberries!

    • Vallery Lomas SAYS | June 7, 2020

      I’m not familiar with flax eggs, but just substitute them how you would normally! I’m sure it will affect texture but that’s ok.

  • Eric SAYS | June 5, 2020

    Based on other oatmeal cookie recipes, I’m guessing this should make about 24 cookies. (Based on the weight of the dough vs. that of other recipes I regularly bake.) I guess I’ll find out soon enough.

    • Vallery Lomas SAYS | June 7, 2020

      Thanks for sharing this!! I will update to add yield 🙂

  • Eric SAYS | June 5, 2020

    Makes 2 dozen. 38g each one. No nuts.

  • Mary Beth Einerson SAYS | June 6, 2020

    Can I use quick cooking oats (not instant)? I bought some for a Cook’s Illustrated recipe and would love a way to use them as I don’t like them as oatmeal etc.

  • Mary Beth Einerson SAYS | June 7, 2020

    Thanks Peggy. I found additional information here.
    Additional information from the King Arthur site is that 1 cup of rolled oats = 99 g and 1 cup of quick cooking oats = 89 g. So I’m going to give the recipe a go with 99 g of my quick cooking oats ground to flour.

  • Emily SAYS | June 8, 2020

    We made oat flour from gluten free rolled oats in our vitamix. I think next time I would do half and half so that we get some of the oat flakes in the cookies. I found them a bit too sweet for us so would maybe remove the white sugar and reduce the chocolate (did I really say that?) and cranberries by 1/4 cup. 🙂

  • Carolyn SAYS | June 11, 2020

    I made it with whole wheat in place of white flour. The kids loved loved these cookies and never complained about whole grains, for once!

  • Patt SAYS | June 16, 2020

    Thanks so much; this was so enjoyable. I appreciated your commentary and humor. I, also, wear my baking & the oat flour idea was great. Keep up the good work & stay safe. Thanks, too, for supporting nurses.
