Preheat your oven to 400°F (200°C) and line a large rimmed baking sheet with parchment paper.

In a large bowl (or stand mixer fitted with the paddle attachment), beat the uncooked breakfast sausage and softened cream cheese together until well combined.

Add the biscuit baking mix, freshly grated sharp cheddar cheese, garlic powder, and chopped parsley. Mix on low speed or knead with clean hands until a cohesive, slightly sticky dough forms.

Use a 1.5-tablespoon cookie scoop to portion the mixture, rolling each portion between your palms into a smooth 1-inch ball. Arrange 1.5 inches apart on the prepared baking sheet.

Bake at 400°F for 15-18 minutes until the bottoms are deeply golden brown and the internal temperature reaches 165°F (74°C).

Let the sausage balls rest on the warm pan for 5 minutes so the melted cheddar sets slightly, then transfer to a platter and serve warm.
