Chocolate Mousse
In a small bowl, add 1 tablespoon of cold water and sprinkle the gelatin powder over it. Let it sit for about 1 minute to bloom.
Add 2 tablespoons of boiling water and stir until the gelatin is completely dissolved. Set aside.
In a mixing bowl, combine the powdered sugar substitute, cocoa powder, heavy whipping cream, and vanilla.
Using a hand mixer, beat the mixture until it becomes thick and forms stiff peaks. Make sure to scrape the sides and bottom of the bowl to fully incorporate everything.
Slowly pour in the dissolved gelatin while mixing. Continue beating until everything is fully blended.
Pour the mixture into a 6-inch round pan or cake mold and refrigerate until fully set.
Whipped Cream Cheese Frosting
In a mixing bowl, beat the softened cream cheese until smooth and creamy. Make sure there are no lumps.
Add the sugar substitute and vanilla extract. Continue beating until fully combined and fluffy.
In a separate bowl, whip the heavy whipping cream until stiff peaks form.
Spread or pipe the frosting over the chilled chocolate mousse.
Add shaved sugar-free chocolate on top, or sprinkle with sugar-free chocolate chips for extra texture and flavor. This gives it that classic Red Ribbon–style look.
