Creating Easy Double Raspberry Mousse Cups is straightforward if you follow these steps:

1. Prepare the Gelatin: In a small bowl, sprinkle the gelatin over the cold water. Let it sit for about 5 minutes until it blooms.
2. Melt the Gelatin: After blooming, microwave the gelatin mixture for about 10 seconds until completely dissolved. Set aside to cool slightly.
3. Blend Raspberries: In a blender, puree the fresh raspberries until smooth. Strain the puree through a fine-mesh sieve to remove the seeds, if desired.
4. Mix Cream Cheese: In a separate bowl, beat the softened cream cheese with the granulated sugar and lemon juice until smooth and creamy.
5. Combine Raspberry and Cream Cheese: Add the raspberry puree and vanilla extract to the cream cheese mixture. Mix until well combined.
6. Whip the Cream: In another bowl, whip the heavy cream until soft peaks form. Gently fold the whipped cream into the raspberry-cream cheese mixture until fully blended.
7. Incorporate Gelatin: Finally, fold the dissolved gelatin into the mousse mixture. Be careful not to overmix, as you want to keep the airy texture.

Once completed, transfer the mousse into serving cups and refrigerate for at least 15 minutes before serving.
