Overmixing the cream: When folding the whipped cream into the peanut butter mixture, be gentle. Overmixing can deflate the airiness and lead to a dense mousse.
-
Ignoring ingredient measurements: Precision is key in recipes. Make sure to measure your powdered sweetener and peanut butter accurately for the best flavor balance.
-
Skipping the sea salt: If using unsalted peanut butter, donβt forget to add a pinch of sea salt. This enhances the flavors and balances sweetness.

Not chilling before serving: For optimal taste and texture, refrigerate the mousse for at least an hour before serving. Chilling allows flavors to meld beautifully.
