Preheat the oven
to 180C/350F/Gas 4. Line a 12-cup bun tray with
paper cases. Sift together the flour, bicarbonate of
soda, salt and cocoa powder. In another bowl, beat
the butter and sugar until light and creamy. Add the
eggs, one at a time, beating well after each
addition; beat in the peppermint. On low speed, beat
in the flour mixture alternately with the milk,
until just blended. Spoon into the paper cases.
Bake for 12-15
minutes, until a skewer inserted in the centre of a
cake comes out clean. Transfer to a wire rack to
cool. When cool, remove the paper cases.
For the filling,
whip the cream and peppermint until stiff. Spoon
into a piping bag fitted with a small plain nozzle.
Pipe about 15ml/1 tbsp into each cake through the
base.
For the glaze,
melt the chocolate and butter, stirring until
smooth. Remove from the heat and stir in the
peppermint essence. Cool, then spread on top of each
cake.
