I love sharing this recipe because it proves that truly great desserts don’t need an oven or fancy techniques. I simply stir, gently cook, and let time do the rest. This milk mousse cake sets beautifully on its own and turns out incredibly smooth, creamy, and melt-in-your-mouth every single time.
This is the kind of dessert I make when I want something comforting, light, and foolproof. It’s mildly sweet, full of natural milk flavor, and soft enough for all ages. Finished with a sprinkle of coconut, it’s perfect for afternoon tea, family desserts, or even baby-friendly treats.

- Ultra-silky texture that melts instantly
- Mildly sweet and easy to adjust
- Simple ingredients you likely already have
Ingredients (6–8 servings, 6-inch mold)
Main ingredients
- 450ml milk (full-fat recommended for best texture)
- 2 egg yolks (room temperature)
- 45g cornstarch
Optional & flavoring
- 35g sugar (adjust to taste, reduce or omit for babies)
- 5g unsalted butter (optional, for extra richness)
- Coconut flakes, as needed (for topping)
Instructions
Mix the base
In a large bowl, add the egg yolks and sugar. Stir until smooth and slightly lighter in color. Add the cornstarch and mix thoroughly until no lumps remain. Gradually pour in the milk while stirring, forming a smooth, lump-free batter.
Cook gently
Pour the mixture into a saucepan. If using butter, add it now. Cook over low heat, stirring constantly and steadily to prevent sticking or curdling. After a few minutes, the mixture will thicken noticeably.
Note: The mousse is ready when it coats the spoon and holds visible lines from a spatula. Do not overcook, or the texture will become too firm.
Set the mousse
Pour the thickened mixture into a container or lightly greased 6-inch mold. Gently tap to release air bubbles. Let it cool at room temperature for 2–3 hours until fully set. No refrigeration is required.
Serve
Once set, unmold or slice directly. Sprinkle coconut flakes on top or decorate with fruit. Serve and enjoy the soft, melt-in-your-mouth texture.
Frequently Asked Questions
Do I need gelatin for this recipe?
No. Cornstarch and egg yolks are enough to set the mousse naturally.
Can I reduce or skip the sugar?
Yes. The recipe works well with less sugar or none at all, especially for baby-friendly versions.
Why must I cook on low heat?
High heat can cause the egg yolks to curdle and ruin the smooth texture. Low and steady heat is key.
Can I refrigerate it to set faster?
It’s best to let it set at room temperature. Refrigeration is optional after setting but not necessary.
How long does it keep?
It’s best enjoyed the same day. If needed, store covered in the refrigerator and consume within 24 hours.
Can I change the topping?
Absolutely. Cocoa powder, matcha, crushed cookies, nuts, or fresh fruit all work beautifully.
