Crispy Peanut Thins - 15 Minute Cookies

These peanut thins are one of the first biscuits I learnt to make. They are super thin making the crispy and unlike a normal peanut cookie. But they are melt in the mouth delicious. I mean what is not to love, chopped peanuts, butter and brown sugar. Oh and don't forget the hint of cinnamon. Plus they are quick to make! You can have these mixed, baked and out of the oven in under 15 minutes.

  • Bake for peanut thins for 5 minutes until they are a deep golden colour and bubbling.
  • Remove them from oven and allow to them cool on the baking sheet.
  • Once cool and crisp you can store them in an airtight container.
  • If you are keeping them for more than 12 hours, layer them with a little baking paper to stop them sticking together.


  1. Use standard AP flour (plain flour) for these cookies. To make them GF just use a standard Gluten Free AP/plain flour.
  2. You can use salted or unsalted peanuts here.
    Or replace the peanuts with almonds, cashew nuts or macadamia nuts.
  3. Use a good quality parchment paper to line your trays or a silicone mat!
