Blancmange cake is a classic dessert that always surprises everyone with its smooth pudding texture and pretty layers. This version is brightened up with juicy tropical fruits and gets extra flavor from chocolate shavings on top. It is perfect for holidays or summer nights when you want a light yet elegant finish to a meal.
The first time I made this was for a spring brunch and people kept going back for seconds. Now it has become my go to when I want an impressive yet stress free dessert.
Ingredients
- Whole milk: Gives the blancmange its creamy texture Choose high quality whole milk for the best flavor
- Granulated sugar: Provides just enough sweetness to let the fruits shine
- Cornstarch: This helps thicken the dessert for a silky tender finish Look for a brand with a fine powder
- Vanilla extract: Adds warmth and extra aroma Use pure vanilla if you can find it
- Gelatin powder or agar agar: Turns the mixture into a sliceable set dessert Always check the expiration date for firmness
- Water: Needed for blooming the gelatin so it dissolves smoothly
- Diced mango peach pineapple: These bring freshness and pops of color Pick ripe but firm fruit for the prettiest layers
- Grated chocolate: For richness and a beautiful garnish A good quality bar will melt nicely on your tongue
- Fresh mint: The perfect green touch for a refreshing finish Snip just before serving
Step-by-Step Instructions
- Prepare the Gelatin or Agar Agar:
- Soak the gelatin powder in cold water for about five minutes until it looks spongy This softens the gelatin and ensures it will blend in smoothly If you choose agar agar skip the soaking and whisk it straight into the cold milk
- Make the Blancmange Base:
- In a medium saucepan whisk together the sugar and cornstarch This evenly blends the dry ingredients before you add any liquid Start pouring in the milk bit by bit whisking constantly so you prevent any lumps When fully mixed set the pan over medium heat and stir the whole time until you see it thicken and just begin bubbling at the edges
- Incorporate Vanilla and Gelatin:
- Take the pan off the heat as soon as you reach that gentle simmer Stir in the vanilla extract right away Drop in the bloomed gelatin and whisk briskly until every bit is dissolved This is important so your cake will set properly
- Layer the Fruit and Blancmange:
- Pour about a third of the hot blancmange into a silicone mold or cake pan Immediately scatter over a layer of your diced tropical fruits Gently spoon in another third of blancmange repeating with more fruit Then finish with the last third of the mixture Smoothing the top helps your cake look neat when unmolded
- Set the Dessert:
- Let everything cool down at room temperature for at least twenty minutes so you avoid condensation in the fridge Move the mold to your refrigerator and leave it there for four hours or overnight so it gets firm enough to slice
- Unmold and Decorate:
- Gently run a thin knife or small spatula around the edges before turning out onto a plate Sprinkle the set surface with grated chocolate so it starts to melt ever so slightly Top with fresh mint for a final flourish and pop of color
- Serve:
- Cut the blancmange into wedges using a sharp knife The jewel toned fruits will peek through the creamy layers Serve chilled straight from the fridge for the best texture

My favorite part is the first chill after layering The kitchen fills with a sweet vanilla scent and I always sneak a peek to see the fruit suspended inside Like my grandmother I love to let kids help with the fruit and decorations
Storage tips
Blancmange keeps for two to three days in the fridge Cover the mold or platter tightly with plastic wrap so it does not dry out If you have leftovers store them in an airtight container to keep the fruit and texture fresh
Ingredient substitutions
You can swop in any soft ripe fruit such as berries or kiwi if you do not have tropical fruit Do not use canned fruit packed in syrup as it can make the set too loose If you want a dairy free version try coconut milk for a richer flavor
Serving suggestions
Slice thick wedges next to lemon cookies or madeleines for a pretty afternoon tea It is also delicious with a squeeze of lime juice or a drizzle of passionfruit puree on each slice For extra flair dot with edible flowers or more fresh fruit
Cultural context
Blancmange has roots in medieval European and Middle Eastern cuisine It was once considered a banquet dish for royal tables because of its lavish look Over time it became a cherished nursery dessert in France and the Caribbean where cooks began layering in exotic fruit and chocolate
