Put cream, vanilla bean pulp and crumbled chocolate in a pot. Slowly heat up while stirring constantly until a smooth mass is formed, bring to the boil briefly once and immediately remove from the heat.
Stir in the Baileys, pour into a bowl and chill overnight. Whisk the mixture with the whisks of the hand mixer first at the lowest setting, then whip briefly at the next higher setting. Pour into a piping bag with star-shaped spout and squirt into approx. 30 metal capsules.
Truffles are best kept cold.
