Preheat the oven to 400 degrees F (200 degrees C). Line a sheet pan with parchment paper.

Combine cream cheese and Cheddar cheese in the bowl of an electric mixer. Mix on medium speed until blended, about 1 minute. Add sausage in golf ball-size pieces while mixer is running and continue to mix until combined with the cheeses, about 1 minute. Add cranberries, 2 tablespoons parsley, onion powder, garlic powder, and red pepper flakes; continue to mix until well blended, about 2 minutes.

Stop the mixer and stir in baking mix with a wooden spoon until it is distributed throughout.

Form 27 golf ball-size sausage balls with your hands or a meatball scoop. Place on the prepared baking sheet, spacing evenly.

Bake in the preheated oven until nicely browned and no longer pink in the centers, about 30 minutes. Drain on paper towels if necessary. Serve warm garnished with remaining parsley.
