Chill your tools: Place a mixing bowl and beaters in the freezer for 10 minutes. Cold equipment helps the cream whip faster and fluffier.
Whip the cream: Add the cold heavy cream to the chilled bowl.
Beat on medium-high until soft peaks form. Do not overbeat. Set aside in the fridge.
Blend the base: In a separate bowl, beat the softened cream cheese until smooth and creamy, about 1–2 minutes.
This step prevents lumps later.
Add flavor: Beat in the cocoa powder, powdered sweetener, vanilla, and a pinch of salt. Mix until fully incorporated and silky. Taste and adjust sweetness or cocoa as needed.
Fold together: Gently fold the whipped cream into the chocolate mixture in two additions.
Use a spatula and light strokes to keep it airy.
Chill: Spoon the mixture into 4 small ramekins or glasses. Refrigerate for at least 30–60 minutes to set. Longer chilling makes it thicker and more mousse-like.
Finish and serve: Top with your favorites—berries, nuts, or a little shaved sugar-free chocolate.
Serve cold.
