1) Put the mascarpone, vanilla, Kahla and a little less than 1/2 of coffee in a medium mixing bowl, blend until everything is smoothly mixed together.

2) In another medium bowl, beat the cream with the icing sugar until smooth, then fold in the mascarpone mix.

3) Place the remaining coffee into large deep plate, quickly dip the biscuits flipping sides, one by one, enough to make one layer in a 11x7 casserole dish.

4) Spread evenly half of the mascarpone mix on top.

5) Repeat with another layer of biscuits and the rest of the mascarpone mix. Refrigerate.

6) Before serving, fill a small sieve with cocoa powder and lightly dust the top.

7) If you are fancy, grate some of bittersweet chocolate or make chocolate curls and scatter them all over
