Here is the recipe for a very creamy, delish mango float.
Condensed milk or sweetened creamer
Prepare the bowl. Mix the cream and condensed milk. Slice the mangoes into thin and small slices. Put a layer of graham crackers at the bottom. Spread a layer of the cream. Put a layer of mango slices. Repeat the last three steps up to the desired thickness. Add a final layer of cream.
Crush graham crackers and put them on the top. Put it in the freezer or refrigerator. Make sure it is cold when served.
