Two-ingredient dessert ready in minutes

Hello friends! I made this mousse for my in-laws and they thought I bought it at the bakery! And it's made with only 2 ingredients, it's very easy!

Ingredients:
60 grams of dark chocolate
3 eggs

STEPS:

Separate 3 egg yolks from the white
Beat the egg whites until stiff
Melt 60 grams of dark chocolate in the microwave or in a bain-marie
Add the melted chocolate to the egg yolks and mix with a whisk
Add the beaten egg whites in 3 times
Mix well from bottom to top without disassembling the mixture
Fill goblets or glasses with the mixture, using a ladle
Level the mixture and let it rest in the fridge overnight
Serve with a sprinkling of cocoa and enjoy!
