Pour the cream into a medium bowl. Using a whisk, a hand blender, or stand mixer with whisk attachment, whisk on low for approximately 3 minutes, or until soft peaks form.
Add the cocoa powder and allulose. Continue whisking (slowly at first, until the powdered ingredients are incorporated) until hard peaks form.
Notes
You can stop whisking at hard peaks stage, or continue to whisk just past the hard peaks form, to where the mousse is quite stiff.
You can store leftover mousse in the refrigerator for a few days.
Use more or less cocoa powder and sugar, depending on your own taste.
