For the milkshake
- 50ml spiced rum
- 4 Oreo cookies, broken into pieces
- 75g vanilla ice cream
- 50ml double cream
- 2 tbsp Guinness
- 1 Oreo cookie
- Place the rum, cookies, ice cream and cream into a blender and whizz until smooth, or add the ingredients to a large jug and use a stick blender.
- Pour into a glass, spoon over the Guinness and top with an Oreo cookie.
For a non-alcoholic milkshake, swap the spiced rum for 50ml double cream and ½ tsp mixed spice. Leave out the Guinness and top with an Oreo cookie.
