In a large mixing bowl, beat the milk, water and extract until blended. Add pudding mix; whisk for 2 minutes. Let stand for 2 minutes or until soft-set. Cover and chill until mixture is partially set. Fold in the whipped cream.
Place half of the cake cubes in a 2 quart glass trifle bowl. Top with half of the cream mixture. Carefully spread with jam. Sprinkle with 1 cup raspberries. Layer with remaining cake cubes, cream mixture and raspberries. Garnish with chocolate curls and mint.
