How to Make Kiwi Mousse Cake
-
Preheat the Oven: Set your oven to 350°F (175°C) and prepare an 8-inch springform pan by lining the bottom with parchment paper. This ensures your cake releases easily after baking.
-
Beat Eggs and Sugar: In a mixing bowl, beat the room temperature eggs and granulated sugar together until the mixture becomes pale, thick, and fluffy, which should take about 4–5 minutes. Add in the vanilla extract for a fragrant touch.
-
Fold in Dry Ingredients: Gently fold the all-purpose flour, baking powder, and a pinch of salt into the egg mixture until just combined. Be careful not to overmix to preserve that light texture.
-
Bake the Sponge: Pour the batter into the prepared pan and smooth the top. Bake for 12–15 minutes or until it’s lightly golden and springs back when touched. Allow it to cool completely in the pan.
-
Prepare the Kiwi Mousse: Blend the chopped kiwis with the sugar and lemon juice until smooth for a delicious fruit base. If you prefer a silkier texture, strain the mixture.
-
Bloom the Gelatin: In a small bowl, sprinkle the unflavored gelatin over the cold water and let it bloom for 5 minutes. Then, gently heat it until fully dissolved, avoiding boiling.
-
Incorporate Gelatin: Stir the dissolved gelatin into the kiwi purée and let it cool until it’s just barely warm. In another bowl, whip the cold heavy cream to soft peaks.
-
Combine and Chill: Fold the whipped cream into the kiwi mixture gently, ensuring a light, airy mousse. Pour this over the cooled sponge and smooth the top. Cover and refrigerate for at least 3 hours until fully set.
-
Make the Kiwi Topping: Blend the remaining 2 kiwis with sugar and lemon juice. Bloom the gelatin in cold water, heat until dissolved, then stir into the kiwi mixture. Allow to cool slightly before pouring over the set mousse.
-
Final Chill: Chill the entire cake in the refrigerator for another 1–2 hours until the topping is glossy and firm.
Optional: Garnish with extra kiwi slices for an eye-catching finish.

Expert Tips for Kiwi Mousse Cake

Kiwi Mousse Cake Recipe FAQs
What type of kiwis should I use for the Kiwi Mousse Cake?
Absolutely! For this recipe, you want ripe kiwis that are slightly soft to the touch. Firm kiwis can lack the sweetness and easy blending required for a smooth mousse, while overripe kiwis may have dark spots. Aim for bright green skin with a little give when pressed.
How should I store my Kiwi Mousse Cake?
Very good question! You can store your Kiwi Mousse Cake in the refrigerator, tightly covered with plastic wrap or placed in an airtight container. It’ll stay fresh for up to 3 days. Just be sure to keep it cold as the mousse is delicate!
Can I freeze the Kiwi Mousse Cake?
Of course! To freeze, wrap individual slices in plastic wrap, then place them in a freezer-safe container. They can last for up to 2 months. When you’re ready to enjoy it, thaw the slices in the refrigerator overnight for the best texture—no reheating needed!
What can I do if my mousse doesn’t set correctly?
No worries! If your mousse isn’t setting, it might be due to the gelatin not being completely dissolved or not blooming properly. Make sure to sprinkle the gelatin over cold water and let it bloom for 5 minutes before heating gently until dissolved. If needed, revisit the steps and try incorporating it when it’s just barely warm.
Is this dessert suitable for those with allergies or dietary restrictions?
Great observation! This Kiwi Mousse Cake contains eggs and dairy, so it’s not suitable for those with egg or milk allergies. For a dairy-free version, you can try using a dairy substitute for the heavy whipping cream. Just ensure that the substitute also has a good fat content for whipping. Plus, always check the ingredients on gelatin packaging for any animal by-products if you follow a vegetarian or vegan diet.
How long does the mousse need to set before serving?
For the best results, let the mousse set in the refrigerator for at least 3 hours; however, if you can, give it a full 5 hours or overnight. This guarantees a beautifully firm, airy mousse that’s easy to slice and serves beautifully!
