Growing up in India, mango season was always something special. We would wait for the sweetest, juiciest mangoes and use them in everything from lassis to ice cream to elegant desserts for family gatherings. This mango mousse cake with a jello insert is inspired by that love for mangoes but takes it to a new level—pairing the fresh, tropical flavor of mango with delicate textures that make every slice feel like a celebration.

I created this mango entremet as a way to bring a touch of elegance to mango season. It’s the kind of dessert I love sharing on the blog because while it looks like something you’d buy from a pastry shop, you can absolutely make it at home with the right steps. And trust me, seeing those layers of creamy mango mousse and the jewel-like jello insert come together is just as satisfying as that first luxurious bite.

Ingredients and substitutes

• Mango – I am using fresh mangoes as they are in season, but you can also use frozen or canned mangoes. If you use canned mangoes, make sure to adjust the sweetness in case the mangoes are sweetened.
• Whipping cream – When making mousse, use full-fat whipping cream with at least 38% fat. Otherwise, the mousse will not set
• Sugar – The mangoes I am using are sweet, so the sugar can be adjusted by a tablespoon more or less.
• Agar-agar – Today, we are using agar-agar instead of gelatin. It’s plant-based and works great to make any fruit jello.

Step-by-step: Mango Mousse Cake with Jello Insert

• Mango Jello: In a saucepan, combine water and agar-agar. Let it sit for 3 minutes. Then, add the mango puree and sugar. Cook over medium heat until the mixture comes to a boil. Strain through a sieve to remove any undissolved agar-agar. Set aside to cool slightly – 2 minutes

• Insert: Pour half the jello into a 6-inch silicone cake pan or 6-inch metal cake pan lined with plastic wrap (see video). Refrigerate the pan for 20 minutes. Save the other half for the top – keep warm or warm it up just before using it again.

• Cookie base: Combine cookie crumbs in a bowl with sugar and melted butter. Pour into an 8-inch springform pan or 8-inch dessert ring lined with dessert sleeves (or run a hot knife around the cake later before unmolding). Spread evenly, then use the back of a glass to press it down firmly. Place it in the fridge to chill for 10 minutes.

• Mango mousse: Place the water, mango puree, and agar-agar in a saucepan. Cook over medium heat until it comes to a boil. Then, cook for 2 minutes to concentrate the mango flavor and evaporate excess moisture. Remove from the heat and strain through a sieve. Let cool for a few minutes until cool but not set (2 to 3 mins). In the meantime, whip the whipping cream with powdered sugar until it peaks. Add the cooled mango puree mixture and gently fold it until well combined.

Assemble

• Remove the chilled cookie crust from the fridge. Pour half the mousse in and spread it evenly. Then, place the chilled set of jello inserts from the 6-inch pan.
• Top with the remaining mousse – use a spoon and offset spatula to smooth it evenly. Then, pour the remaining Jell-O. (the half we saved previously)
  Pro tip – I like to pour over a spoon so it doesn’t disturb the mousse (see video).
• Carefully place the pan in the fridge for at least 4 hours to chill, preferably overnight. Garnish with some fresh mango slices.

Tips for success

• Use full-fat heavy cream to make the mousse; otherwise, the mousse will be too soft and not set. 
• I’ve used agar-agar, a plant-based, vegetarian alternative to gelatin, to keep this eggless and vegetarian, but you can also use regular gelatin. But regular gelatin will take longer to freeze, so adjust the timeline accordingly.  
• I’ve used fresh mango, but you can also use frozen mango for this cake. 
• The jello insert and the top are made at the same time. If the mixture solidifies, just warm it in the microwave for a few seconds to bring it back to a pouring consistency. 
• The mousse is made with fresh cream, which will start to lose volume in about 48 hours. It might get softer and lose its shape, but the insert will still stay firm.
