2 tbsp
24-carat gold dust or metallic luster dust
(optional)
Method:
Sift
the flour, cocoa, and salt into a medium bowl.
Beat the butter, confectioners' sugar, and vanilla
in a large bowl with an electric mixer at high speed
until creamy.
Mix in the dry ingredients to form a
smooth dough. Press the dough into a disk, wrap in
plastic wrap, and refrigerate for 30 minutes.
Preheat the oven to 300°F/150°C/gas 2. Set out a
cookie sheet. Lightly dust a work surface with
confectioners' sugar and roll out the dough to a
thickness of 1/4 inch (5 mm).
Use a 3-inch (8-cm)
cookie cutter to cut out the cookies. Gather the
dough scraps, re-roll, and continue cutting out
cookies until all the dough is used.
Use a spatula
to transfer the cookies to the cookie sheet.
Lightly brush the tops with the gold dust.
Bake
for 12-15 minutes, or until firm to the touch. Transfer to racks to cool.
