Ingredients

(Tip: You can find the complete list of ingredients and their measurements in the recipe card below.)

• fresh or frozen raspberries

• granulated sugar

• unflavored gelatin powder or gelatin sheets

• heavy cream (cold)

• cream cheese or mascarpone (softened)

• vanilla extract

• lemon juice (optional, for brightness)

• digestive biscuits, graham crackers, or sponge cake for the base

• unsalted butter (melted, if using cookie base)

Directions

1. Prepare the base:
   Crush the cookies into fine crumbs. Mix with melted butter and press into the bottom of a springform pan. Chill in the refrigerator while preparing the mousse.
   (Alternatively, place a thin layer of sponge cake at the bottom of the pan.)

2. Make raspberry puree:
   In a saucepan, cook raspberries and sugar over medium heat until they release juices. Simmer for a few minutes, then strain through a sieve to remove seeds. Let the puree cool.

3. Bloom the gelatin:
   Dissolve gelatin in cold water and let it sit for a few minutes. Gently warm until fully melted (avoid boiling), then stir into the raspberry puree. Let cool to room temperature.

4. Whip cream and combine:
   Beat heavy cream to soft peaks. In a separate bowl, beat softened cream cheese with vanilla extract until smooth. Gently fold the raspberry-gelatin mixture into the cream cheese. Then fold in whipped cream until fully combined.

5. Assemble the cake:
   Pour the mousse mixture over the prepared base. Smooth the top with a spatula. Chill in the refrigerator for at least 4–6 hours, or until fully set.

6. Decorate and serve:
   Once set, remove from pan. Garnish with fresh raspberries, whipped cream, or mint leaves if desired. Slice and serve chilled.

FAQs

1. Can I use frozen raspberries?

Yes, frozen raspberries work well. Thaw them first and cook as directed for the puree.

2. What can I use instead of gelatin?

You can substitute with agar-agar for a vegetarian option. Adjust quantities as agar sets more firmly.

3. Can I make this cake ahead of time?

Absolutely. This dessert is perfect for making a day in advance since it needs several hours to chill and set.

4. Is it okay to skip the cookie base?

Yes, for a lighter version, you can pour the mousse directly into individual glasses or ramekins.

5. How do I ensure the mousse sets properly?

Allow enough chilling time (minimum 4 hours), and ensure the gelatin is fully dissolved and evenly mixed.

6. Can I make this in individual servings?

Yes, divide the mousse and base among glasses or jars for a beautiful, portioned dessert.

7. What type of cream should I use?

Use heavy cream or whipping cream with at least 35% fat for stable peaks and a creamy texture.

8. How can I prevent lumps in the gelatin?

Bloom gelatin in cold water first, then melt gently and mix thoroughly into the raspberry puree.

9. What should I do if my mousse doesn’t set?

If the mousse doesn’t firm up, it may be due to insufficient gelatin or under-chilling. Chill longer or recheck gelatin quantity next time.

10. Can I add a glaze or topping?

Yes, a thin layer of raspberry jelly or fruit glaze on top adds shine and a professional look.
