Lightly butter a 33 x 23cm baking dish and set aside.
On a floured work surface roll the dough into a rectangle, roughly 40 x 30cm.
With a spatula spread the almond filling over the dough. Make sure to cover all the dough by spreading the filling thinly.
Roll the dough tightly. Cut the dough with a serrated knife into 12 rolls. They should be about 2.5cm thick each.
Place the rolls in the baking dish, cover and let the rest for half an hour. In the meantime, preheat the oven to 180°C or 350°F.
Brush the rolls with the egg wash and bake them for about 20 minutes, until golden.
Let them cool slightly before drizzling the melted chocolate and sprinkling the almond flakes. Enjoy!
