Combine the Irish cream liqueur, vodka, coffee liqueur, Gingerbread Syrup and ice cream in a cocktail shaker. Add ice and shake well. Pour into four chilled martini glasses. Top each with a generous dollop of whipped cream and a sprinkling of gingerbread cookie crumbs.
Add the sugar, water, cloves, cinnamon and ginger to a small saucepan. Bring to a boil over medium-high heat, stirring until the sugar has dissolved. Lower the heat and simmer for 5 minutes. Remove from the heat and let cool to room temperature before using, about 20 minutes. Cover and refrigerate for up to 2 weeks.
