Banana, pear and chocolate crumble

It was ages I wanted to try this recipe from the wonderful book Crumbles by Camille Le Foll. And then one merry day I had all the ingredients in the house and some friend to dine with, so I though it was the right moment!

3 pears
2 bananas
3 pieces of candied ginger

For the crumbles:
100 g of butter
100 g of flour
100 g of sugar
60 g of grained hazelnut
2 tablespoon of cocoa
Ginger powder

Crumble all the ingredients for the crumble in a food processor.
Peel pears and bananas and cut them in thick slices. Dice the candied ginger.
In a oven dish layer pears, banana and candied ginger. Cover with the crumbles and cook in a preheated oven for 15-20 minutes.
Serve warm.
