Ingredients Equipment Method Notes

Ingredients
  

  • 300 grams flour or 2 cups
  • 1/2 teaspoon salt
  • 1 teaspoon baking powder
  • ½ teaspoon baking soda
  • 400 grams brown sugar or 2 cups packed
  • 2 eggs
  • 1 cup melted butter slightly cooled, browning butter is optional, but worth it (see notes)
  • 60 grams hot water or 1/4 cup
  • 400 grams rolled oats or 4 cups
  • Mix-ins nuts, chocolate chips, and/or raisins (optional!)
  • 1 sprinkle Flaky sea salt (to taste)

Equipment

  • Cookie sheet
  • Cooling rack
  • Slip mat or parchment paper

Method
 

  1. Preheat oven to 350ºF.
  2. Line a cookie sheet with a slip mat or parchment paper.
  3. Add flour, salt, baking powder, and baking soda to a large bowl. Whisk to combine.
  4. Add in brown sugar and eggs, then stir with rubber spatula until fully combined.
  5. Mix cooled, melted (browned or not!) butter into the batter.
  6. Fold in rolled oats and any mix-ins of your choice.
  7. Using a cookie scoop (or a big spoon), spoon the dough onto the sheet pan spaced 2-3 inches apart, then bake for a total of 15 minutes.
  8. At the 12 minute mark, pull the cookies out briefly to tap the pan onto the counter 2-3 times. This will spread the cookies out just slightly and add some chew. Then return to the oven for the final 3 minutes.
  9. After removing from the oven, top with your flaky sea salt. Then, let sit on the pan for 3-5 minutes before transferring to a cooling rack for another 5-10 minutes. Enjoy!

Notes

This recipe can easily be done by hand or with a stand or hand mixer. During my testing, I tried both the stand mixer and by hand, and the results were the same.
If you need instructions on how to brown butter, I am a big fan of this blog post from King Arthur Baking. It has lots of visuals to help for your first few go-arounds.
