3 tablespoons coco powder
1 bar (8 ounces) reduced-fat cream cheese
3/4 cup heavy cream
1/3 cup sugar
2 packages (3 ounces each) soft ladyfingers
In a medium bowl, mix coco powder with 3 tablespoons boiling water until dissolved. Add 1 1/2 cups cold water; set aside.
With an electric mixer, beat cream cheese with heavy cream and sugar until light and fluffy.
Spread a few tablespoons of cream-cheese mixture in the bottom of a 2-quart serving dish. Separate ladyfingers. One by one, dip a third of ladyfingers in coco, then arrange in bottom of dish. Spread with a third of cream-cheese mixture. Repeat twice with remaining ladyfingers, coco, and cream-cheese mixture (can be refrigerated, covered, up to 1 day).
Dust with cocoa just before serving.
