Beat the filling: Whip cream cheese and butter until fluffy. Blend in sweetener, salt, and vanilla. In a separate bowl, whisk cold cream to soft peaks; fold into cream-cheese mixture.
Freeze fat-bomb centers: Scoop 1-tablespoon mounds onto parchment, about 10. Freeze 45 min–1 hour until firm.
Prep the “crumbs”: Mix crushed pork rinds and cinnamon in a shallow dish.
Coat & shape: Roll each frozen mound into a ball, then coat thoroughly in crumbs, pressing gently so they stick. Return to freezer 15 min.
Flash-fry: Preheat air fryer to 400°F. Spray basket lightly with avocado oil. Air-fry bombs 35–45 seconds, just until crumb exterior is sizzling and golden.
Serve immediately for hot-cold contrast, or freeze again for later snacking.
