- Can I use frozen raspberries?
- For the batter, yes. For the filling/decoration, fresh is best as frozen berries release too much water and can make the cream runny.
- The marshmallows hardened too fast.
- Pop them back over the steam or in the microwave for a few seconds to loosen before mixing with the cream.
Raspberry Marshmallow Mousse Cake
Tart raspberries and sweet marshmallows find perfect balance in this cake. The marshmallow isn't just a sweetener; when melted, it creates a silky, elastic base for the mousse that holds up beautifully between the cake layers, hugging the fresh fruit.

Instructions
1
✓
Preheat oven to 350°F (180°C). Beat eggs and sugar until pale. Whisk in butter, milk, and vanilla.
Tip: Dissolving the sugar into the eggs creates a stable foam.
2
✓
Fold in flour, salt, and baking powder. Bake for 25-30 minutes. Cool completely.
Tip: Salt balances the sweetness of the upcoming marshmallow filling.
3
✓
Melt the marshmallows in a double boiler. Whip the cream with confectioners' sugar. Fold the lukewarm marshmallow into the cream.
Tip: Ensure the marshmallows cool to body temperature so they don't deflate the cream.
4
✓
Halve the cake. Spread filling, dot with raspberries, and top with the second layer. Frost the outside.
Tip: The tartness of the berries cuts through the rich cream.
5
✓
Decorate with remaining berries. Chill for 2 hours to set.
Tip: The gelatin in the marshmallows needs time to firm up.
