Petit Gâteau Mango

Learn step-by-step how to create Petit Gâteau Mango with perfect molten centers, smooth mango mousse, and vibrant tropical flavor. A French-style molten lava cake infused with the sweetness of ripe mango for a refreshing tropical dessert. This cake literally looks like a real mango. I show you how!

Petit Gâteau Mango is a mango-flavored version of the classic French molten lava cake (often called petit gâteau au chocolat). The name “petit gâteau” literally means “small cake” in French — it refers to individual-sized cakes that are soft and moist on the outside, but have a gooey, molten center inside.

What is Petit Gâteau Mango?

Petit gâteau literally means “small cake” in French, and traditionally, it refers to a mini molten chocolate cake with a rich, flowing center. The Petit Gâteau Mango reimagines that concept using fresh mango purée instead of chocolate, giving the dessert a fruity, tropical flair.

The golden sponge encases a molten mango core that oozes out once you slice it open — warm, silky, and irresistibly aromatic. It’s a perfect harmony of flavors: the sweetness of mango balanced by a buttery cake shell. Paired with a scoop of vanilla ice cream or a dollop of whipped cream, this dessert feels like summer in every spoonful.

In a Petit Gâteau Mango, the traditional chocolate is replaced or complemented by mango purée or mango coulis, giving it a tropical, fruity twist. The result is a warm, soft cake with a runny mango filling that flows out when you cut into it — like a lava cake, but with bright, tangy-sweet mango flavor instead of chocolate.

Here’s what typically makes it special:

Outer layer: A light, buttery sponge or cake made with eggs, sugar, butter, and a touch of flour.

Center filling: A molten mango core, usually made from fresh mango purée, sugar, and sometimes white chocolate or cream to create a rich texture.

It’s a fusion dessert that combines French pastry technique with tropical fruit flavor — popular in modern patisseries and fine dining restaurants, especially in Asia and tropical regions.

 Why You’ll Love This Dessert

• A tropical upgrade to a French classic – Replaces the traditional chocolate with vibrant, fresh mango.
• Perfect for special occasions – Impressive yet simple enough for home baking.
• Heavenly texture contrast – Soft cake exterior and luscious molten mango center.
• Pairs beautifully with ice cream – Especially vanilla, coconut, or passion fruit flavors.

When Is Mango Season?

The best time to make Petit Gâteau Mango is during mango season, when fresh mangoes are at their sweetest and most aromatic. In Indonesia and most parts of Southeast Asia, mango season typically runs from October to March. During these months, the markets are overflowing with golden varieties like Harumanis, Manalagi, and Gedong Gincu — all perfect for creating a rich, fruity molten center.

During mango season, fruits are not only more flavorful but also more affordable. Fresh, ripe mangoes are ideal for desserts like Petit Gâteau Mango, mango float, mango sticky rice, or even blended into refreshing drinks.

If you’re craving this dessert outside the mango season, don’t worry! You can easily use frozen mango chunks or store-bought mango purée to achieve the same bright, tropical flavor all year round. The key is to choose a mango that tastes naturally sweet and vibrant, so your Petit Gâteau captures the essence of summer in every spoonful.

Ingredients of Petit Gâteau Mango

Mango Puree

• Fresh Mango Chunks – The base of your purée; choose ripe, sweet mangoes for the best flavor and natural color. They give the dessert its signature tropical taste.
• Sugar – Balances the tanginess of the mango and enhances its natural sweetness. You can adjust the amount based on how ripe your mangoes are.

Mango Filling

• Mango Purée – Provides a smooth, fruity foundation for the filling with a rich mango aroma.
• Passion Fruit Purée – Adds a hint of tartness and brightness to balance the sweetness of mango, creating a more complex flavor.
• Mango Chunks – Adds texture to the filling for a fresh, juicy bite in contrast to the smooth mousse.
• Gelatin Powder – Helps the filling set while still keeping it soft and slightly wobbly.
• Water – Used to bloom (hydrate) the gelatin before mixing it into the fruit purée.

Mousse

• Mango Purée – Brings the same tropical flavor into the mousse, tying the layers together harmoniously.
• White Chocolate Couverture – Adds creaminess, mild sweetness, and helps stabilize the mousse structure.
• Heavy Cream – Whipped into the base to create a light, airy texture that melts in your mouth.
• Gelatin Powder – Ensures the mousse holds its shape while remaining silky and smooth.
• Water – Used to bloom the gelatin so it dissolves evenly when combined with the warm ingredients.

Coating

• Cocoa Butter – Provides shine and a smooth texture for the outer shell; it helps the coating set evenly.
• White Chocolate Couverture – Creates a sweet, glossy coating that pairs beautifully with mango.
• Yellow Food Coloring (Oil-Based) – Forms the main vibrant mango hue.
• Orange Food Coloring (Oil-Based) – Adds depth and dimension to the yellow, giving a realistic mango gradient.
• Red Food Coloring (Water-Based) – Used sparingly to tint areas for a sun-ripened blush effect.
• Green Food Coloring (Water-Based) – Mimics the natural green tones near the mango stem for a lifelike finish.
• Lemon Extract – Enhances the aroma with a fresh citrus note that brightens the entire dessert.

How to Make Petit Gâteau Mango

Puree

Start by preparing the base flavor that ties the whole dessert together.
Place fresh mango chunks and sugar in a small pot. Heat the mixture over medium heat until it begins to boil, then reduce the heat and let it simmer for about 10 minutes to intensify the flavor.

Once done, turn off the heat and blend the mixture with a hand blender until smooth. This purée will be used in several parts of the recipe, so set it aside to cool completely.

Mango Filling

Next, let’s make the fruity molten center.

First, bloom the gelatin by combining it with water and letting it sit for a few minutes. In a separate bowl, combine the rest of the mango filling ingredients and stir to mix evenly.

Once the gelatin has bloomed, melt it gently over boiling water and pour it into the mango filling mixture. Stir until everything is well combined and slightly thickened.

Pour about 35 g of the filling into each mold and freeze for at least 4 hours, or until solid. These frozen mango centers will form the gooey surprise inside your petit gâteau.

The Mango Mousse

While waiting for the filling to set, prepare the mousse layer.
Bloom the gelatin again by mixing it with water and setting it aside. Then, melt the white chocolate and let it cool slightly.

In a medium mixing bowl, whisk the heavy cream using an electric mixer until it reaches almost stiff peaks. Add the mango purée and the melted white chocolate, whisking again until fully combined.

Finally, melt the bloomed gelatin over boiling water, pour it into the mousse mixture, and whisk until smooth. Transfer the mousse into a piping bag for easy assembly.

Assemble

Now comes the fun part — bringing everything together.
Remove the frozen mango filling from the mold. Pipe the mango mousse into a clean mold until it’s about ¼ full, then gently place the frozen filling in the center.

Continue piping the mousse until the mold is completely filled. Tap or slam the mold lightly on the counter to release any trapped air bubbles, then add more mousse if needed.

Once done, freeze for at least 8 hours or overnight until fully set.

Coating

To give your petit gâteau its glossy, professional finish, prepare the coating.
Start by melting the cocoa butter over low heat until completely liquid. Pour it over the white chocolate and mix until the chocolate melts and blends smoothly. Strain the mixture into a glass, then add the yellow and orange oil-based food coloring to create a bright mango hue. Stir until evenly colored and set aside.

Next, mix the red and green water-based food colorings with a little lemon extract in separate bowls — these will be used for airbrushing and shading.

Remove the frozen mousse cakes from the mold and insert a skewer into each for easy dipping. Once the chocolate coating reaches 36°C, dip each mousse cake quickly and evenly.

Place the coated cakes on a tray, then use an airbrush to spray red coloring near the stem end and green coloring on the tip, creating a lifelike mango appearance.

Finally, let the petit gâteaux chill in the refrigerator for at least 2 hours before serving to set the coating and ensure the perfect texture.
