Line the bottom of your springform pan with baking paper, close it, and line the sides with a strip of plastic for easy removal. Cut the ladyfingers with a bread knife to the same height as your cake pan. Set aside the leftovers, which you will use for the base.
Dip the fingers in the coffee and place them upright against the edge of the springform pan. Now fill the bottom as much as possible with the leftovers. You can cut them to fit if necessary. Spoon some coffee over them as well.
Separate the eggs; you can use the egg whites in another recipe. Whisk three egg yolks with the sugar and vanilla in a large bowl until frothy. In another bowl, combine the mascarpone and liquid cream and whip until thick and fluffy. Mix both mixtures together. Spread half of the mixture in the pan and completely cover with ladyfingers dipped in coffee. Smooth the top with the mascarpone mixture, and pipe thick dollops of the remaining mixture around the edges.
Let it cool and set for 4 hours. Sprinkle with cocoa powder just before serving.
