The name alone is reason enough to give this one a go. It tastes like a grown-up banana shake with an added hint of coffee. Serves 1
For the banana syrup: Heat the sugar and water until the sugar is fully dissolved. Add mashed banana and stir. Leave to cool. Strain liquid, discard solids. Leftover banana syrup will keep for a day in the fridge.
For the cocktail: Place all ingredients except the garnish into a blender and blitz. Pour into a milkshake glass and garnish with whipped cream and a slice of banana, if desired.
