Preheat the oven to 190°C. Line a large baking tray with parchment paper.
Melt the butter/ spread, let it cool.
Whiz the walnuts in a small blender until you get coarse breadcrumbs.
Mix the dry ingredients in a large bowl, then add the butter, honey and 1-2 spoonful of water. Knead it into a dough. If you have time, let it rest in the refrigerator for 15-30 minutes.
On a lightly floured chopping board roll out the dough to 3 mm thickness, then using a glass or cookie cutter, cut circles out. Roll out any leftover dough and stamp out more cookies.
Place the cookies on the tray and bake for about 10 minutes until golden brown.
Keep them in an airtight jar.
