In a medium bowl, combine two packages of mascarpone cheese and 1 can of condensed milk.
Add 1/4 cup of boiling water to a small bowl with 1 tablespoon instant coffee. Allow to cool 5 minutes, then dip sugar coated biscuits in the coffee one by one until moistened.
Put 1 layer of the biscuits into a larger ovenproof dish, then spread the cream on top, reserving a portion. Make another layer of the coffee biscuits, then spread another layer of cream.
Finally, put some chocolate powder in a sieve and sprinkle on top of the dish. Place in refrigerator for 45 minutes, then serve.
