Break one bar of chocolate in half and put the rest to one side.
Chop the 1/2 bar of choc into chunks - not too small!
Gently stir in the conserve, just enough to make a marbled effect.
Spoon the mixture into the paper cases dividing it equally and bake for approximately 12-15 minutes (check using toothpick test), until well risen and pale golden in colour.
Leave to stand for a few minutes then cool on a wire rack.
Once cooled, cover the cupcakes with the remaining chocolate.
Break choc into pieces and melt gently in microwave or in a bowl over pan of simmering water.
Coat each cupcake in a generous layer of chocolate and finish with a pink icing swirl or heart design.
