1. Crush the otap cookies in a bowl. Slice the mango into small chunks.
2. In another small bowl, mix the cream and milk until combined.
3. To prepare the float, start with a layer of crushed otap in a glass. Drizzle with the milk mixture before adding a mango later. Add a scoop of Selecta Super Thick Classic Vanilla ice cream. Repeat the layers until the glass is filled, and top the last ice cream scoop with crushed otap.
4. Feel free to add other toppings or mix up the layers as you wish! Best served chilled.
