This no-bake Filipino dessert layers sweet mangoes, cream, and graham crackers into a dreamy frozen treat that tastes like summer in every bite. Incredibly simple to assemble with no fancy equipment or special techniques required, mango float is the ultimate make-ahead crowd-pleaser that delivers maximum wow factor with minimal effort.
Peel and slice mango flesh away from the pit into thin slices about 1/4 inch thick. Set aside the nicest-looking slices for the top layer and dice any remaining pieces to fill gaps.
Using an electric mixer on medium-high speed, whip the cold heavy cream until soft peaks form, about 3–4 minutes. Reduce speed, gradually add condensed milk and vanilla, then beat until stiff peaks form.
Arrange a single layer of graham crackers on the bottom of a 9x13 inch baking dish, breaking crackers as needed to cover the entire surface snugly.
Spread about one-third of the cream mixture evenly over the crackers, then arrange a layer of mango slices over the cream, filling gaps with smaller pieces and gently pressing them in.
Add another layer of graham crackers, one-third of the cream, and another layer of mango slices; repeat once more until all ingredients are used.
Spread the remaining cream mixture smoothly across the top all the way to the edges, then arrange your prettiest mango slices in an attractive pattern on top.
Cover the dish tightly with plastic wrap pressed directly against the surface and freeze on a flat surface for at least 4 hours, or overnight for best texture.
Let the mango float sit at room temperature for 5–10 minutes before slicing; use a sharp knife dipped in warm water for clean cuts, wiping between slices.
Notes
Choose ripe mangoes: Look for mangoes that yield slightly to gentle pressure and have a sweet fragrance near the stem end for the best flavor.
Chill your bowl: Place the mixing bowl in the freezer for 15 minutes before whipping cream to achieve better volume and stability.
Don't overwhip: Stop mixing as soon as stiff peaks form to avoid turning the cream into butter.
Work quickly: Have all ingredients prepped before you start assembling, as the cream can begin to soften at room temperature.
Frozen mangoes: If using frozen mango slices, thaw completely and pat thoroughly dry before using to prevent a watery dessert.
Lighter version: Substitute heavy cream with Cool Whip (thawed); fold condensed milk in gently instead of beating.
Storage: Cover tightly and store in the freezer for up to 2 weeks, or refrigerate for a softer texture for up to 3 days.
Prevent freezer burn: Press plastic wrap directly onto the surface of the dessert before covering the dish.
Make-ahead tip: This dessert is best prepared the night before serving, allowing the graham crackers to soften and flavors to meld.
Variations: Try chocolate graham crackers, coconut cream in place of half the heavy cream, or mix in other fruits like strawberries, peaches, or kiwi.
