Ingredients You’ll Need

Getting the ingredients right is half the fun, and thankfully, this recipe calls for simple yet vibrant components that each add a special touch. From the tropical zing of lime to the creamy richness of whipped cream, every element plays a key role in creating this unforgettable dessert.
- White granulated sugar: Sweetens the cake and mousse perfectly without overpowering the natural mango flavor.
- Large eggs: Provide structure and moisture to the base for a tender crumb.
- Neutral flavoured vegetable oil: Keeps the cake moist while letting the tropical flavors shine.
- Milk: Adds a little softness to the cake batter and helps balance the texture.
- Plain flour (all purpose flour): Forms the foundation of the cake’s light, soft crumb.
- Desiccated coconut: Infuses a lovely texture and aromatic depth to the cake base.
- Baking powder: Ensures the cake rises nicely and stays fluffy.
- Salt: Just a pinch enhances all the flavors beautifully.
- Zest of one large lime: Adds a fresh, citrusy brightness that complements the mango exquisitely.
- Thickened cream (or whipping/heavy cream), cold: Whipped into stiff peaks to create that luscious, airy mousse topping.
- Ripe mangoes: The star of the show—pureed to make the vibrant mango mousse absolutely irresistible.
- Icing sugar (powdered sugar): Sweetens the mousse subtly without weighing it down.
- Cold water: Used to gently dissolve the gelatin for a perfectly set mousse.
- Powdered gelatin: Gives the mousse its light, yet stable texture.
- Mango slices and shaved coconut: For the delightful finishing touches and extra tropical flair.
How to Make Mango Mousse Cake Recipe
Step 1: Prepare the Lime Coconut Cake Base
Start by preheating your oven to 160C (140C fan) or 325F. Line and grease an 8-inch springform pan to ensure a smooth release later. The combination of coconut and lime zest in the cake base really sets the tropical tone for the mousse to come. Whisk the eggs and sugar together until smooth, then add oil and milk for moisture. Folding in the flour, desiccated coconut, baking powder, salt, and lime zest will give you a batter bursting with flavor and texture. Pour this into your pan and bake for about 30-35 minutes—a toothpick test will tell you it’s done. Once out, press the top gently with a glass to flatten the slight dome. This little trick makes the mousse settle beautifully on top.
Step 2: Cool the Cake
Keep the outer ring of the springform pan on and let the cake cool to room temperature, or pop it in the fridge for a bit after it’s cooled slightly. This step is crucial because you don’t want warm cake under your mousse layer, or it might melt or become watery. Patience here really pays off.
Step 3: Whip the Cream for the Mango Mousse
Pour the cold cream into a chilled bowl and use an electric beater to whip it into stiff peaks. This step is the foundation for the mousse’s light, airy texture, so be careful not to overbeat or you’ll risk it becoming grainy. Set the whipped cream aside chilled until you’re ready to fold the mango mixture in.
Step 4: Prepare the Mango Puree and Gelatin Mixture
Peel and chop two large ripe mangoes, then blend them into a silky smooth puree. Measure out 2 ¼ cups of this luscious mango goodness. In a small saucepan, sprinkle gelatin over cold water and let it soften for a few minutes (this is called blooming). Gently heat on low just until the gelatin dissolves fully—no boiling allowed—to avoid any lumps. Combine the gelatin mixture with the mango puree, sugar, and lime zest for that perfect balance of sweet and zesty.
Step 5: Fold Mango Puree into Whipped Cream
Adding the mango puree in small portions to the whipped cream and folding gently with a spatula is key to keeping the mousse light and airy. Work carefully to mix them together without deflating the cream—this step makes the magic happen for your mousse consistency.
Step 6: Assemble and Chill
Remove the lining paper from inside the springform pan, replacing it with acetate strips if you have them for a neat look. Pour the mango mousse over your cooled cake base and gently shake or tap the pan to level the surface. This dreamy Mango Mousse Cake Recipe needs at least 4 hours in the fridge (overnight is even better) to set perfectly before serving.
Step 7: Decorate and Serve
Once set, carefully remove the springform ring and peel away the acetate strips or lined baking paper. Adorn the top with fresh mango slices and a sprinkle of shaved coconut for a finishing flourish that screams tropical indulgence.
How to Serve Mango Mousse Cake Recipe

Garnishes
Adding freshly sliced mango and a light dusting of shaved coconut not only boosts the visual appeal but enhances the tropical flavor. You can also sprinkle a tiny bit of lime zest on top to brighten the overall taste and add a touch of elegance.
Side Dishes
This mango mousse cake pairs wonderfully with a chilled glass of sparkling wine or a tropical cocktail for an indulgent treat. For a non-alcoholic option, try a fresh lime soda or iced green tea to balance the sweetness.
Creative Ways to Present
If you want to impress guests, serve this cake on a beautiful glass cake stand and surround it with edible flowers or fresh mint leaves. For smaller gatherings, slice into elegant individual portions and place each on a decorative plate with a drizzle of passionfruit sauce for extra tropical flair.
Make Ahead and Storage
Storing Leftovers
Keep your leftover mango mousse cake covered in the fridge, ideally in a cake keeper or with plastic wrap to prevent it from absorbing fridge odors. It should stay fresh and delicious for up to 3 days. Beyond that, the mousse might start to lose its velvety texture.
Freezing
You can freeze the cake for up to 1 month if necessary. Wrap it tightly in plastic wrap and then foil to protect the delicate mousse. When ready to enjoy, thaw overnight in the fridge to preserve the best texture.
Reheating
This Mango Mousse Cake Recipe is best served chilled and is not suitable for reheating. Keep it beautifully cool for that refreshing tropical bite every time.
FAQs
Can I use canned mango instead of fresh mango for the mousse?
Fresh mangoes provide the best natural flavor and texture for this mousse, but if fresh mango isn’t available, canned mango in juice (not syrup) can work. Drain it well and taste for sweetness before proceeding, adjusting sugar as needed.
What if I don’t have gelatin? Can I substitute it?
Gelatin is essential for setting the mousse firm but delicate. You can try agar-agar as a vegetarian substitute, but the texture will differ slightly. Follow the conversion instructions on the agar-agar package carefully.
Can I make the cake base gluten-free?
Yes! Substitute the plain flour with a gluten-free all-purpose flour blend that includes xanthan gum for structure. The flavor will still shine, but the texture might be slightly different.
How ripe should the mangoes be?
The sweeter and riper your mangoes, the better the mousse. Look for mangoes that give slightly to gentle pressure and have a strong fruity aroma for maximum flavor.
Can I prepare this cake a day ahead?
Absolutely! In fact, preparing it the day before allows the mousse to set perfectly and the flavors to meld wonderfully, making your serving experience even better.

Ingredients
Lime Coconut Cake Base
- ¾ cup white granulated sugar (150g / 5.3oz)
- 2 large eggs, room temperature
- ⅓ cup neutral flavoured vegetable oil
- 1 tablespoon milk
- 165 g plain flour (all purpose flour) (1 ¼ cups / 5.8oz)
- ⅓ cup desiccated coconut (30g / 1oz)
- 1 teaspoon baking powder
- ¼ teaspoon salt
- Zest of one large lime
Mango Mousse
- 1 cup thickened cream (or whipping cream or heavy cream), cold (250ml)
- 2 large ripe mangoes (you’ll need 2 ¼ cups puree)
- ¼ cup icing sugar (powdered sugar) (33g / 1.2oz)
- 1 teaspoon lime zest
- ¼ cup cold water (60ml)
- 2 teaspoons powdered gelatine
- Mango slices and shaved coconut for topping
Instructions
- Preheat and Prepare Pan: Preheat your oven to 160°C (140°C fan) / 325°F. Line the base of an 8-inch springform pan with baking paper, grease the sides, and line those with baking paper as well to prevent sticking.
- Make Cake Batter: In a large bowl, whisk together the eggs and sugar until combined. Add the vegetable oil and milk, whisking again until smooth.
- Add Dry Ingredients: Add the plain flour, desiccated coconut, baking powder, and salt to the wet mixture. Whisk gently until just combined, then fold in the lime zest with a spatula.
- Bake Cake Base: Pour the batter into the prepared pan and bake for 30-35 minutes, or until a toothpick inserted comes out with a few moist crumbs attached.
- Flatten Cake Top: Once out of the oven, gently press the dome of the cake down with a glass to create a flat surface for the mousse topping.
- Cool Cake: Carefully release the spring clip but keep the outer ring on. Allow the cake to cool to room temperature, then chill in the fridge after 5-10 minutes room temp cooling to speed up the process.
- Whip Cream: Pour the cold thickened cream into a large mixing bowl and beat with an electric beater until stiff peaks form. Be careful not to overwhip to avoid graininess. Chill until needed.
- Prepare Mango Puree: Cut mango flesh from the skin and blend it in a food processor or blender until smooth. Measure out 2 ¼ cups of puree and set aside.
- Soften Gelatine: In a small saucepan, pour the cold water and sprinkle the gelatine powder evenly over the surface. Let it sit for 3-4 minutes to soften.
- Dissolve Gelatine: Heat the saucepan on low, stirring constantly until the gelatine has fully dissolved. Do not let it boil; remove from heat if bubbles form. Ensure no lumps remain.
- Mix Mango Gelatine: Add the icing sugar, lime zest, and dissolved gelatine mixture to the mango puree and whisk to combine thoroughly.
- Fold Mousse: Add about one-quarter of the mango mixture to the whipped cream. Using a spatula, gently fold it in without stirring to avoid deflating the cream. Repeat adding the mango mixture in portions until fully combined, scraping the bottom to incorporate all.
- Prepare Pan for Mousse: If using acetate strips, remove baking paper from the pan sides and place acetate strips along the inside circumference to prevent sticking and ease removal.
- Assemble Cake: Pour the mango mousse gently over the cooled cake base and gently shake the pan to level the mousse surface.
- Chill Cake: Refrigerate the cake for at least 4 hours, or preferably overnight, until the mousse is fully set.
- Serve: Run an offset spatula between the cake and pan edges to loosen if using baking paper. Unlock and remove the springform pan ring carefully, then peel off the baking paper or acetate strips. Decorate with mango slices and shaved coconut. Slice and serve.
Notes
- Use lime zest both in the cake base and mousse to add a refreshing citrus aroma.
- Room temperature eggs help create a better batter consistency.
- Gently folding the mousse is essential to maintain its light, airy texture.
- Do not overheat gelatine or let it boil to avoid lumps in the mousse.
- If acetate strips are unavailable, baking paper can be used to line the pan sides.
- Chilling the cake overnight improves mousse set and flavor melding.
