Can I make this Dark Chocolate Raspberry Mousse Cake without gelatin?

Yes, you can prepare this cake without gelatin by substituting agar-agar or using a stabilized whipped cream method. Agar sets more firmly than gelatin, so use a smaller amount and dissolve it fully for a smooth mousse texture.

What’s the best chocolate percentage for a dark chocolate mousse cake?

A dark chocolate between 60% and 70% cocoa works best. This range melts smoothly, gives a rich taste, and pairs perfectly with the raspberry layer.

Can I use frozen raspberries instead of fresh?

Yes. Frozen raspberries work well for compote or puree and offer consistent flavor year-round. Just cook off excess moisture so the raspberry layer sets properly.

How long does a mousse cake need to chill before serving?

A mousse cake should chill for at least 4–6 hours. However, overnight chilling provides the cleanest layers and the best mousse texture.

Can this cake be made ahead for parties or holidays?

Yes. This recipe is ideal for making ahead. You can prepare it 24 hours in advance or freeze it when planning several days ahead.
