Working quickly, dip each lady finger, one at a time into the espresso, on both sides. Don't let the ladyfingers sit in the espresso, as they will absorb way too much liquid. A quick dip.
Place each ladyfinger side by side, to fill in the space of the pan.
Once your bottom layer has been filled with ladyfingers, put half of your custard on top and spread smooth.
Repeat with another layer of ladyfingers.
Finish with the remainder of your custard.
Dust generously with cocoa to finish.
Enjoy!!!
