Pop the Hazelnut Chocolate Spread jar - minus the metal lid - in a microwave and warm through for 10-15 seconds. Put a large tablespoonful in the bottom of two tall glass tumblers and swirl the spread around to make a marbled effect.
Put the remaining spread and milk in a blender and whizz until smooth. Add about half the ice-cream and whizz again until smooth.
Pour into the glasses and top with scoops of the remaining ice-cream, swirls of whipped cream and chocolate decorations.
For Easter, buy mini chocolate mousse-filled chocolate bunnies and push onto wooden skewers to serve with the thick-shakes.
