5ozroasted unsalted cashew nuts(140 gr), blended into powder
3cupsall purpose flour(380 gr)
In a bowl, add in butter, icing sugar and mix just until well combined. Add in powdered milk and mix. Add in egg yolk and mix again, just until combined.
Add in vanilla extract, baking powder, blended cashew and mix just until well combined. Add in the flour, ⅓ at a time, mixing to combine each time. Switch to spatula when the dough is heavy for the mixer. Form into a ball and cover with cling film to prevent it getting dry.
Roll out ⅓ of dough at a time to a more or less 1 cm thickness, in between cling film. Since the dough is a bit sticky using the cling film will make it easier to roll.
Dip a cookie cutter in the flour and cut out the dough. Place them on a baking tray with baking sheet. Gently brush the top with egg yolk. Place cashew halves on top, pressing a bit into the dough. Bake at 150ºC (300ºF) preheated oven for 10-15 minutes or until golden brown and fully cooked. Cool completely on a rack.
