Hazelnut DrinkDISCOVER MORE
Mix the Hazelnut Drink with the sugar, pour it into a baking dish, forming a not too thick layer (1-2 cm). Put in the freezer for a few hours or until it has solidified.
Meanwhile, prepare the crumble: turn on the oven at 170°. Mix the two flours with cocoa and sugar, add the yolk, vegetable margarine, hazelnuts and a pinch of salt. Knead with your fingertips until you get a homogeneous mixture. Spread the dough on a baking sheet covered with parchment paper, spread it out with a fork in an irregular way. Bake in the oven for 10-12′.
Remove from the oven and break it into large crumbs, let cool.
Break up the hazelnut drink, put it in a blender with the coffee. Blend until the mixture is smooth and creamy enough.
Pour into iced glasses and serve accompanied by the hazelnut crumble.
