Preheat the oven to 180 degrees. Grease and line a 9-inch cake tim with baking paper.
In a large bowl cream together the butter, caster sugar and vanilla extract with an electric mixer. Add the eggs, one at a time and mix continuously.
Sift in the flour and cocoa powder into the mixture and mix. Add the milk, bit by bit and continue mixing.
Spoon the cake mixture into the prepared tin and bake in the oven for 20 minutes until a skewer comes out clean.
Allow to cool for a few minutes and place on a cooling rack to cool. Once the cake is completely cooled cut it into 8 triangles.
Turn the cake triangles upside down for flatter surface, if needed. Decorate with smarties, strawberry laces, jelly tots, sprinkles or your sweets of choice! Dust with icing sugar to look like snow.
Snap off the curved part of the candy cane and insert the straight part into the flat bottom of the cake triangle.
