Flourless Oatmeal Cookies

Carolyn
These flourless oatmeal cookies are chewy, gluten free, and delicious! They're easy to make and even easier to eat (so be careful!). No flour oatmeal cookies are one of my favorites!

Ingredients
  

  • ½ cup unsalted butter, room temp (1 stick)
  • ¾ cup brown sugar
  • ¼ cup white sugar
  • 1 egg
  • 2 ½ cups quick cooking oats* Make sure they're labeled gluten free for gluten free cookies
  • ½ teaspoon baking soda
  • ½ teaspoon kosher salt

Instructions
 

  • Preheat oven to 350 degrees Fahrenheit.
  • Cream butter and both sugars in a stand mixer on medium speed for four minutes. The mixture should look lighter and fluffier.
  • Add the egg and beat on medium speed until combined. Scrape the bowl with a spatula if necessary.
  • Add quick cooking oats, baking soda, and kosher salt to the bowl. Beat on medium speed until thoroughly combined.
  • Use a small portion scoop to scoop 5 cookies onto a silpat or parchment lined sheet pan. The cookies spread so be sure to give them space!
  • Bake for 11 minutes, until the outsides are brown but the center still looks underdone. The cookies will set up more as they cool. If the entire cookie looks done or golden brown when you pull them out of the oven, they will be overbaked.
  • Repeat until all the cookie dough is gone.
  • Let them cool on the sheet pan, then enjoy!

Notes

*Old fashioned oats will not work in this recipe! For a thicker cookie, increase the quick-cooking oats from 2 ½ cups to 2 ¾ cups. 
Do not overbake the cookies! They won't look done when you pull them out of the oven. Let them cool and set up on the pan. As they cool, they will harden and turn into a cookie!
