Ingredients

Instructions

  • In a medium bowl, whisk together the gluten-free flour, baking soda and salt until evenly combined. Set aside.
  • Melt butter in a saucepan over medium heat. Once the butter is melted start to whisk constantly. First the butter will begin to foam, then after a couple of minutes it will begin to brown on the bottom of the saucepan. Turn off the heat as soon as the solids turn brown and the butter gives off a nutty aroma. Pour into a glass mixing bowl to prevent burning.
  • Add the brown sugar and granulated sugar. Whisk to combine. Add the egg, egg yolk and vanilla and whisk until smooth and creamy.
  • Using a rubber spatula, mix in the dry ingredients until well combined.
  • Drop spoonfuls of peanut butter and fluff into the dough and stir once or twice to incorporate only slightly. You should still have separate pockets of peanut butter and fluff within your cookie dough. Do not over mix.
  • Cover the bowl and refrigerate for at least 1 hour.
  • Preheat the oven to 350°F. Scoop the cookie dough (about 2 Tablespoons of dough per cookie) and place a few inches apart on the baking sheets. Bake for 10-12 minutes, until golden and the center is set.
  • Let cool for 5 minutes then transfer to a wire rack to continue cooling. Sprinkle with flaky salt before serving. Enjoy!

Notes

Gluten-Free: Use a high-quality gluten-free flour that contains xanthan gum. I use King Arthur Gluten-Free Measure-for-Measure Flour for best results. 
Dairy-Free: Skip steps 2-3 and simply use melted dairy-free butter. (Dairy-free butter will not brown.) 
Nut-Free: Use sunflower seed butter in place of the peanut butter. 
To Make-Ahead: The dough can be stored in an airtight container in the fridge for up to 3 days in advance. If too firm to scoop, let it sit out at room temperature for 10-15 minutes. Dough balls can also be frozen for up to 3 months, just add 1-2 extra minutes to the baking time.
To Store: Let cookies cool completely, then store in an airtight container for up to 4 days. 
To Freeze: Store in an airtight container or freezer bag and freeze for up to 3 months. Thaw at room temperature for 1-2 hours.
