Here is my version of this dessert:
What you need:
1/2 cup hot water
¼ cup hot chocolate powder
Hershey's chocolate syrup
2 whole eggs
2 tablespoon granulated sugar
2 cups mascarpone cheese at room temperature (You could probably use regular cream cheese if you can't find mascarpone)
extra hot chocolate mix
What you do:
1. Mix the hot water and the hot chocolate powder. I actually ended up putting in a squirt of hershey's syrup to give it a more rich chocolatey flavor.
2. Divide the egg whites into a medium sized mixing bowl and the yolks into a heat proof mixing bowl. Place a small pot with just an inch or so of water in the bottom on your stove and start it simmering. Put the bowl with the egg yolks in it on top of the pot of water and add 1 TBS sugar to the yolks. You don't want the water to touch the bottom of the bowl. You could also use a double boiler for this if you're lucky enough to have one. Whisk the egg yolks and sugar over the hot water(don't let the water boil) for about five minutes, whisking the entire time. It will get really fluffy. If they start to look like scrambled eggs you've over cooked them and need to start over. Try a lower heat and faster stirring.
With a clean whisk or, preferably, an electric mixer, beat the egg whites until they start to look a little bubbly and fluffy. Add in 1 TBS sugar and continue to mix until they form stiff peaks. That means that when you stop your mixer and pull it out of the egg whites the foam stays in a peak shape instead of falling back into the bowl.
3. Now fold the mascarpone cheese into the egg yolk mixture, only folding in half the cheese at a time. Then fold the mascarpone/yolk mixture into the egg whites, again only folding in one half at a time. Adjust sugar level to suit your taste, just remember you're also going to be layering this with lots of sweet chocolate, so it's better if it's not too sweet.
4. Place 3 ladyfingers in the bottom of your serving dish. Brush generously with hot cocoa mixture. Now spoon some of the mascarpone mixture on top of that. Next you sprinkle some of the hot cocoa powder on top of the cheese. (I wanted mine to be really chocolatey so I put a drizzle of hershey's syrup on top of the powder) Repeat these layers 1-2 times, ending with a layer of ladyfingers. Top with whipped topping, a sprinkle of hot cocoa powder, and a drizzle of Hershey's syrup. Garnish with a wafer straw cookie and enjoy.
