Preheat the oven to 180℃
Line 2 baking sheets with parchment
Beat together the margarine, sugar until light and fluffy.
Sift in the flours, vanilla and salt to form a very soft, but not sticky dough.
Make large marble sized balls and place on the baking sheet (try to make an even number). Flatten with the back of a fork.
Bake for 15-17 minutes
Dust with a fine coating of cocoa powder
Cool on the baking sheet for a couple of minutes before moving to a wire rack.
Make the filling: Whisk the margarine and cream cheese with the icing sugar, coffee until it is all incorporated. Place in the fridge to firm up before using.
Once completely cool, sandwich the cookies together with the cream.
