  • Preheat oven to 180 Celsius / 350 Fahrenheit.
  • Put all ingredients in a bowl and mix with a fork.
  • Roll small balls of dough (ca 15g each) with your hands (or use a small cookie scoop) and flatten them on a baking sheet.
  • Wet a fork and press on cookies to create a criss cross pattern.
  • Bake 8 -10 minutes, until the edges are firm. (8 minutes = soft centre, 10 minutes = overall crunchy)
  • Let cool completely before eating. They are very soft when just out of the oven, but will become crunchy once cooled.
  • Store in an airtight container.



Try getting hold of a peanut butter that contains 100% peanuts and nothing else. If you have a food processor, you can even make your own. I mixed a bit of sea salt into the dough and sprinkled a bit more on top. It's the salted caramel effect - sweet and salty together are just crazy good.
