Cook's noteKeep only the cream cold — soften the cream cheese and bring the peanut butter to room temperature so everything folds together smoothly.

This is an already low-carb, no-bake mousse where nearly all the calories come from the cream, cream cheese and peanut butter fat. To lighten it you have to trim some of that fat and richness — the result will be a bit less dense and less luxuriously creamy, but still pleasant.
125 ml heavy whipping cream → 75 ml heavy whipping cream whipped, folded with 60 g plain Greek yoghurt (0-2% fat)
Cuts a big chunk of fat while keeping some whipped body. The mousse will be looser and slightly tangy rather than richly creamy, and holds its shape less well.
120 g cream cheese → 120 g light/reduced-fat cream cheese
Keeps the same structure and cheesecake flavour but lowers fat. Texture is marginally softer and less rich.
60 g natural peanut butter → 45 g natural peanut butter plus 1 tbsp powdered peanut flour (PB2-style) mixed with a…
Keeps strong peanut flavour with less fat and calories. Slightly less smooth and a touch drier on the tongue.
60 g powdered Swerve sweetener → 40 g powdered Swerve sweetener
Reduces cloying sweetness with no calorie change (it's a sugar alcohol) but the mousse will taste noticeably less sweet, which pairs well with the tangy yoghurt.
