  • 1 cup creamy peanut butter
  • 1 large egg
  • ½ cup firmly packed brown sugar **see notes below


  • Preheat the oven to 350 degrees.
  • Combine all of the ingredients in a large mixing bowl and whisk to combine.
  • Take tablespoon sized scoops of dough and roll them into balls.
  • Place on a parchment lined baking sheet about 2″ apart.
  • Use the back of a fork in a cross pattern and press into the cookies to flatten them.
  • Bake for 8 minutes.
  • Allow to cool on a wire rack before storing in an airtight container.


***If your dough is still too soft, this can be caused by not packing the brown sugar firmly enough or that some peanut butter brands can be oilier than others (making them softer/creamier), which might keep things from coagulating. In rare cases, this can also happen if you use a medium egg instead of a large egg.
Try using 1 cup of granulated sugar instead of the 1/2 cup of brown sugar or increasing your brown sugar to 3/4 cup or 1 cup depending on how much moisture you need to absorb. This should give you a  thicker dough.
You could also try chilling the peanut butter to make it a bit thicker before working with it.
