Step 1: In a blender, combine the mango puree, heavy cream, sweetened condensed milk, and vanilla extract. Blend until the mixture is completely smooth and creamy.
Step 2: Pour the blended mango cream mixture evenly into individual serving glasses or a large dessert dish. Ensure there's enough space for toppings.
Step 3: Place the glasses or dish in the freezer for at least 4 hours, or until the float is firm and set. For best results, chill overnight.
Step 4: Once the float is set, garnish generously with chopped nuts, granola, fresh mango slices, whipped cream (if using), mint leaves, and fresh berries (if desired).
Step 5: Serve immediately and enjoy your refreshing Creamy Mango Float!
