Combine coffee, sugar, and liqueur and stir until combined and sugar is dissolved. Let mixture cool.
Using electric mixer, beat whipping cream until it just thickens, gradually adding powdered sugar as it thickens. Remove from mixer and with rubber spatula, gently fold in mascarpone cheese and flavorings.
Place cake layers on plate or tray, and using pastry brush, liberally brush one side of cake with coffee mixture, then turn slices over and brush the other side, as well.
Place 4 slices of the layers of coffee-soaked cake into a clear glass dish, cutting layers to fit into dish, if necessary. Then spread on half of the mascarpone mixture, edge to edge.
Place the remaining 4 slices of the cake layers on top of that. Then spread the remaining mascarpone mixture on top.
Dust top with cocoa, edge to edge. Cover with plastic wrap and let sit in refrigerator overnight, or at least 8 hours before slicing and serving. Slice and serve cold…. Enjoy with fresh strawberries! ~
