Add the flour with the eggs and Nutella, then pour the preparation into a removable cake tin, and bake at 180°C for 15 minutes.
Melt 200g of white chocolate and add green powdered food colouring. Melt the other 100g of white chocolate and add the red powdered food coloring.
Coat the cones in the green chocolate and sprinkle sugar decorations onto them. Make lines with the red chocolate on the remaining cones.
Fill the cones with whipped. Place them on the cake and sprinkle everything with icing sugar. Serve slices and enjoy!
