Roughly chop the chocolate and melt in a warm water bath. Melt butter in a small saucepan. Crumble the base very finely. Mix espresso and 2 tablespoons of boiling water. Place melted chocolate, butter, base, vanilla sugar, espresso, almonds and liqueur in a bowl and mix well.
Put the mixture in a cool place for about 1 1/2 hours. Then form about 40 small balls with cool hands. Turn into chocolate flakes or cocoa as desired and dust with icing sugar. Tastes very good when cooled
waiting time approx. 1 1/2 hours
