In a platter or bowl, mix grated Edam cheese and cheddar cheese.
In molds or parchment paper lined shaped pan, spread combined cheeses. (You can also just sprinkle in free form rounds on the pan) Top with almond shavings and sprinkle hazelnuts.
Bake in a preheated oven at 400°F for 5 to 8 minutes. Avoid burning the sides. Remove from oven and allow to cool for a few minutes then slowly remove cheese from parchment paper and transfer to a platter.
In another pan or oven safe bowl, pour heavy cream and add chocolate bar. Heat in the oven just before removing cheese pans. Allow for chocolate bar to melt, about 2 to 4 minutes. Opt to use a microwave, double broiler or chocolate melter for melting chocolates.
Transfer melted chocolates into a disposable plastic or icing dispenser. Cut a small hole on the plastic or use a small tip for the icing dispenser.
Drizzle melted chocolates on the nutty cheese crisps.
