Mango float is a Filipino icebox cake: layers of graham crackers, sweetened whipped cream, and thin slices of ripe mango, chilled until the crackers turn soft and cake-like. It takes about 20 minutes to assemble in an 8×8 inch dish, needs at least 6 hours in the fridge, and serves 9 to 12.
The one step that decides whether it slices cleanly is the cream. Whip it to soft peaks first. Only then does the condensed milk go in.

You need 3 large ripe mangoes, 2 cups of cold heavy whipping cream, one 300 ml can of sweetened condensed milk, about 200g of plain graham crackers, a pinch of salt, and vanilla if you like it. Another ⅓ cup of crushed grahams goes on top, also optional.
That is roughly 480 ml of cream to 300 ml of condensed milk, so the cream is the larger part. It holds the air; the condensed milk sweetens it and gives the filling its dense, almost custard-like taste. Pick plain grahams rather than cinnamon or honey flavored ones, so the mango stays the main flavor.
Choosing Mangoes That Slice Into Clean Strips
Carabao (Manila) mangoes are what most Filipino cooks use. Ataulfo, sold as honey mangoes in many stores, are the closest match: sweet, with very little fiber, so they slice into smooth strips. A ready mango gives slightly when you press near the stem and smells sweet there. Rock hard fruit tastes sour, and very soft fruit falls apart and leaks juice into the cream.
Slice the cheeks about 3 to 4 mm thick so the strips bend without tearing. Keep the neatest ones for the top. Lay the slices on paper towels for a few minutes before layering. Wet mango is the main reason a mango float weeps a puddle in the bottom of the dish. Taste a slice too: if your mangoes are on the tart side, a slightly thinner layer keeps the float balanced.
No ripe mangoes? Canned mango slices in syrup work. Drain them well, pat them dry, and expect a sweeter float with less of the fresh tang.
Whipping the Cream Before the Condensed Milk Goes In
Cold matters here. Chill the bowl and beaters for 10 minutes and use cream straight from the fridge. Beat it on high for 3 to 4 minutes, until it forms soft peaks that fold over at the tip. Then turn the mixer to low and pour in the condensed milk in a thin stream, with the vanilla and salt.
The condensed milk loosens the cream at first, so keep beating until the mixture is smooth and thick enough to hold soft folds on the spatula. Stop there. Beaten until stiff, the cream turns grainy and starts heading toward butter. If the filling stays thin and pourable, the cream was too warm or under whipped before the milk went in.
Layering a Mango Float in an 8×8 Dish
Use a glass or ceramic 8×8 inch dish. Glass shows the layers. Build it in this order:
- Grahams: one layer of whole crackers on the bottom, broken by hand to fill the corners and gaps.
- Cream: a generous layer of the filling, spread right to the edges so it soaks the crackers evenly.
- Mango: one even layer of slices laid close together, with little overlap.
- Cream again: the rest of the filling, smoothed over the fruit so none of it shows.
- Top: the reserved mango slices, and a scattering of crushed grahams if you want them.
The first cracker layer always looks patchy. It disappears under the cream. For a taller float like the one in my photos, you can add a second layer of grahams after the mango, before the last of the cream; a 200g pack covers two layers in this dish.
For the crumb topping, crush a few crackers in a zip bag with a rolling pin, leaving some small pieces for texture. Cover the dish tightly with plastic wrap and chill.
Is the Mango Float Set? Checking at 6 Hours
After 6 hours the top should feel firm under a light press, and a knife should go through to the bottom with the grahams cutting like soft cake. If they still crunch, give it a few more hours. Overnight is better. It is also the easiest way to make it a day ahead of a party, since the float only gets more cake-like as it sits.
Each square should show clean stripes of graham, cream, and mango. If the layers slide apart when you lift a piece, it needs more time, or the cream was not whipped enough. A long knife wiped clean between cuts gives the neatest edges.
Heavy Cream vs All Purpose Cream in Mango Float
This recipe uses heavy whipping cream, which whips to soft peaks and sets into a fluffy, sliceable filling. Many Filipino families make mango float with canned all purpose cream instead, because it is what the stores there sell. All purpose cream has less fat and will not whip into peaks. Chill it overnight and whisk it with the condensed milk until thick, and the float will be softer and more spoonable, more like a pudding than a cake.
How Long Mango Float Keeps, and Freezing It
Keep it tightly covered in the fridge for up to 3 days. After the second day the mango releases more juice and the layers soften further. It still tastes good. The stripes just blur.
For clean party squares, put the set float in the freezer for 1 to 2 hours before cutting. Leaving it frozen longer turns it into an ice cream cake: the mango gets icy and the cream loses its soft texture when it thaws, so I do not freeze it for storage. The whipped filling can be made a few hours ahead and kept cold until you assemble.
Mango Float Swaps Readers Ask About
Can I make Biscoff mango float?
Yes. Swap the grahams for Biscoff cookies in the same layers. They soften the same way and add a caramel spice that goes well with mango; if you like that flavor, my Biscoff cookies use it too.
What can I use instead of graham crackers?
Marie biscuits, Biscoff, or plain digestive biscuits all work. Ladyfingers soak up too much and go mushy, so keep them for tiramisu.
Can mango float be made vegan or dairy free?
Use chilled coconut cream whipped like my coconut whipped cream, sweetened condensed coconut milk, and grahams made without honey. It sets a little softer.
Is mango float the same as mango graham cake?
Yes. Mango float, mango graham cake, and mango refrigerator cake are all names for this same chilled layered dessert.

Mango Float Recipe
This mango float recipe is a Filipino no bake icebox cake made with ripe mangoes, chilled heavy cream, sweetened condensed milk, and graham crackers. It takes about 20 minutes to assemble in an 8x8 inch dish, chills for at least 6 hours or overnight, and serves 9 to 12. The cream is whipped to soft peaks before the condensed milk goes in, so the filling stays thick enough to hold clean layers while the crackers soften into a cake-like base. Make this Filipino mango float, also called mango graham cake, for potlucks, birthdays, Noche Buena, or summer parties, or build it in small jars. Biscoff cookies can replace the grahams. Keep it covered in the fridge for up to 3 days.
Ingredients
- 3 large ripe mangoes (Carabao or Ataulfo mangoes preferred)
- 2 cups heavy whipping cream, chilled
- 1 can (300 ml) sweetened condensed milk
- 1 tsp vanilla extract (optional)
- 1 pack graham crackers (around 200g)
- 1/3 cup crushed graham crackers (optional topping)
- Pinch of salt
Instructions
- SLICE THE MANGOES: Peel the mangoes and slice them into thin strips for layering. Set aside a handful of the most even, attractive slices for the top layer of the dessert.
- WHIP THE CREAM: In a chilled mixing bowl, beat the cold heavy cream using an electric mixer until soft peaks form. Slowly pour in the sweetened condensed milk, add vanilla extract if using, and a pinch of salt. Continue whipping until the mixture becomes smooth and fluffy but not stiff.
- CREATE GRAHAM BASE: Arrange whole graham crackers in a single layer at the bottom of an 8x8-inch glass or ceramic dish. Break crackers as needed to fill gaps evenly.
- ADD CREAM LAYER: Spoon and spread a generous layer of the whipped cream mixture over the graham cracker base, smoothing the surface with a spatula to cover all edges.
- ADD MANGO LAYER: Lay mango slices in a single, even layer over the cream. Use enough to mostly cover the surface, placing the strips close together without overlapping too much.
- ADD FINAL CREAM LAYER: Spread another layer of the whipped cream mixture over the mangoes, completely covering the fruit. Smooth out the top surface.
- ADD DECORATIVE MANGO TOPPING: Arrange the reserved mango slices neatly on top for presentation. If desired, sprinkle the surface with crushed graham crackers for added texture and visual appeal.
- CHILL: Cover the dish tightly with plastic wrap and refrigerate for at least 6 hours, or overnight, to allow the graham crackers to soften and the layers to set properly before serving.
Notes
Use ripe but firm mangoes, such as Carabao or Ataulfo, and pat the slices dry so the float does not weep. Whip the cold cream to soft peaks before adding the condensed milk, and stop as soon as the filling is smooth and holds soft folds. Chill at least 6 hours, ideally overnight, so the graham crackers turn soft and cake-like. For neat squares, freeze the set float for 1 to 2 hours before cutting. Store covered in the refrigerator for up to 3 days; longer freezing makes the mango icy.
