Preheat the oven at 170 degrees celsius
Line two large baking pans with baking paper and set aside
Beat the room temperature butter and icing sugar in a stand mixer or a hand mixer, for approximately 10 minutes. The mixture should be light and fluffy
Add the egg yolk and mix. Add the vanilla essence and brandy
Roast the almonds on the stove top until slightly brown, crush it a little with your hands and add to the mixture
Add the flour, a little at a time, until a soft and pliable dough is formed. Dough should be soft but not sticky. You may not require all of the flour
Use a small ice-cream scoop to scoop the dough. Make round balls and flatten a little. Make a little indent in the center of each cookie
You can also make a round ball and roll the dough in the palms of your hand to form an elongated shape. Bend it a little to form a crescent shape
Place the cookies on a baking sheet and bake for 20 minutes or until the cookies are slightly golden brown on the edges
Remove from the oven and whilst still hot place the cookies in a bowl of icing sugar and coat the cookies with the sugar
Place in an airtight container and cover cookies with more icing sugar
