Follow these simple steps to create your Decadent Raspberry Cheesecake Mousse Cups:

1. Prepare Raspberries: In a small bowl, mash the fresh raspberries with granulated sugar. Set aside to allow the flavors to meld.
2. Whip Cream: In a separate bowl, whip the heavy cream until stiff peaks form. Be careful not to over-whip; it should be fluffy and light.
3. Mix Cream Cheese: In another bowl, beat the softened cream cheese, powdered sugar, vanilla extract, and lemon juice until smooth and creamy. If using gelatin, dissolve it in water and add to this mixture.
4. Combine Mixtures: Gently fold the whipped cream into the cream cheese mixture until fully incorporated. This will create a light and airy mousse.
5. Layer Cups: In serving cups, layer the cheesecake mousse, mashed raspberries, and crushed graham crackers (if using). Repeat the layers until the cups are filled. Top with extra raspberries for garnish.
