Remove lining paper from sponge cake layers. Put 1 layer on serving plate (flat side up) & frost top surface only w/chilled filling. Gently place 2nd layer atop filling (flat side down). Refrigerate till ready to serve.

To Serve: Generously dust top of cake w/icing sugar & scatter fresh mint leaves over dusted surface. (This was inconsistent w/the pic which showed the mint leaves mounded in the center of the top of the cake, so choose the look you prefer).

NOTE RE PREP STEP 2: My pref would be to use a simple coffee filter to strain the coffee & remove the grounds. I'd just squeeze it to get all the coffee for the cake or press the filter w/the round side of a tbsp to manage that step easily. :-).
