In a food processor add the Savoiardi Cookies and the sugar and pulse until completely crushed, then add the mascarpone and the cream, combine. Then add the coffee a little at a time and combine (start with 1 tablespoon if the dough sticks then leave at that). The dough will be thick.
Place the dough in a glass bowl, cover with plastic and refrigerate 3-4 hours.
Remove from the fridge and roll the dough into golf ball size balls (or slightly smaller if desired). Freeze for approximately 15-20 minutes.
While they are in the freezer, melt the chocolate, place half the chocolate in a bowl over a pot of boiling water, stir until melted, remove from heat then add the remaining chocolate stirring until smooth, let cool slightly.
Remove from the freezer, place a toothpick in every ball and dip into the melted chocolate, place on a parchment paper lined cookie sheet with the toothpick still attached.
While the chocolate is still wet, add chocolate curls. Let harden. Then dust with cocoa. Enjoy!
**my house is quite cool so they became firm without the need of refrigeration.
