Drain the cherries well. Beat the eggs and icing sugar with the whisk of the hand mixer until creamy. Slowly add oil and mineral water, stir in. Add flour, baking powder and hazelnuts, stir in. Mix cherries and 2 tablespoons of flour.
Carefully fold into the dough. Pour into a greased Bundt pan (2 litres capacity) sprinkled with breadcrumbs. Bake in a preheated oven (electric cooker: 175 °C/ convection oven: 150 °C/ gas: level 2) for 60-70 minutes. Leave the cake to rest in the mould for 10 minutes and turn it over onto a grid. Sprinkle with nut syrup and allow to cool completely. Let the cake glaze become liquid in a hot water bath. Cover the cake with it. Allow to dry slightly and sprinkle with brittle. Allow to set completely.
