Scoop ice cream into balls and hold in freezer. Slice banana and cut washed strawberries into halves. Gently warm waffles and Nutella in a microwave for 10 secs. Build tower by placing a waffle onto the plate, squeeze a generous amount of Nutella over the top then add sliced bananas, add another waffle. Place ice cream ball into cone and place upside down on top of the waffle stack, drizzle with more Nutella and garnish with bananas, strawberries and mixed nuts.
Top tip: To prevent Nutella from becoming less pliable hold it in a bath of warm water with the nozzle facing upwards.
