To blanch and peel almonds: bring 2 cups water to a boil and add almonds. Boil for 1 minute then drain. After a couple minutes, when the almonds have cooled, squeeze them out of their skins and discard the skins. Chop the almonds and set aside.
Mix the liqueurs and ¼ cup milk. Spread the lady fingers out in a flat pan or dish and drizzle the liqueur/milk mixture over the top. Turn the lady fingers over to coat both sides. The goal is to just infuse the liqueur into the lady fingers enough to soften them a bit, but not for them to get soggy.
Line a round glass or metal bowl with parchment paper. You can use any round bowl, and try to use one that is as dome shaped as possible.
Now line the parchment-lined bowl with the infused lady fingers. Lay them very close to each other and break one or two in half as needed to fill any empty spots. Gently press the lady fingers into the shape of the bowl. Leave about 4-5 lady fingers aside for the bottom layer.
In a metal bowl, beat the heavy cream and powdered sugar until stiff peaks have formed.
Divide the whipped cream in two. In one half, add the cocoa powder and mix will. Using a soft spatula or frosting knife, spread the whipped cream/cocoa powder mixture inside the layer of lady fingers, smoothing the mixture all around to create an even coat over the lady fingers.
With the other half of the whipped cream, add the chocolate chunks, almonds and vanilla extract. Mix well and spoon into the center of the cake, next to the cocoa powder layer. The cavity should now be filled. Now place a final layer of lady fingers along the bottom to form the bottom layer. Cover and chill for at least 3 hours. This is a dish best served chilled. To serve: Turn the cake over onto a pretty serving dish and remove parchment paper. Sprinkle the entire surface of the cake with cocoa powder. Slice with a serrated knife into wedges to show off the various layers. The cake will last for 3 days in the refrigerator. When storing any leftover cake in the fridge, keep it in its round bowl so it will retain its shape until the next serving. Do not freeze because the whipped cream does not hold up well in the freezer. I hope you enjoy this fabulous cake! Please let me know if you try any variations!
