Line a baking sheet with a silicone mat or parchment paper
Preheat the oven to 180°C (160°C fan)
Mix the butter and powdered (icing) sugar for about 2 minutes until light and creamy
Mix in the vanilla extract
Add the flour, unsweetened coconut baking powder and salt
Beat until just combined to form a soft dough
Roll out the dough (6mm) and cut out cookies (I usually use 6cm round cookie cutter)
Bake until golden brown for 15 minutes on the middle shelf of your oven
Remove from the oven but leave the cookies on the baking sheet for 5 minutes before transferring to a cooling rack . The cookies will be soft when removed from the oven, but will crisp as they cool
Store at room temperature in an airtight container for up to 7 days
