Place sieved flour and salt, together with the granulated and brown sugar in a large mixing bowl.
Add the hot water to the peanut butter and mix until smooth. This will loosen the peanut butter. Leave to cool.
Add egg to the flour and the cooled peanut butter mixture.
Mix together very well using hands until the ingredients form a dough. You should be able to have a ‘clean’ mixing bowl with no crumbs.
Fill the cookie press half full and use a template of your choice. Place cookies 3 finger widths apart on the baking tray.
Bake in preheated oven at 350F, 180C, Gas 4 for 12 minutes or until the edges just begin to slightly brown.
Remove from the oven, cool for 5 minutes on the baking tray then transfer to cooling rack
Once cooled, melt some chocolate (choose your favourite!) in a microwave. Do 15 second intervals until the chocolate has melted, and dip the cookies into the melted chocolate. Then dip the cookies in the chopped cashews and leave to set.
