For the punch balls, crumble the cake, mix with the rum. Crumble the chocolate and melt in a water bath.
Mix the melted chocolate with the cake crumbs until you can’t see any more of the cake. Form balls from the mixture and roll in chocolate sprinkles.
For the Krampus, put two balls together with an almond stick, put almond sticks as horns on the head, cut triangles from the voucher cherries for the tongue and press in sugar pearls for the eyes.
