Preheat the oven to 350℉/177℃.
Prepare baking or cookie sheets by lining them with parchment or foil paper and spray with cooking spray. Set aside.
Combine your dry ingredients in a medium mixing bowl: flour, baking powder, onion powder, garlic powder, Italian seasoning, and salt. Mix well.
Add crumbled sausage, cream cheese, and flour mixture in another large bowl. Using your hands, thoroughly mix all ingredients until fully combined.
Next, add milk and melted butter. Continue mixing with your hand until fully incorporated.
Finally, add grated cheddar cheese and mix well.
Scoop about a tablespoon of the sausage mixture and shape it into a 1-inch ball using your palms. Then place it on a prepared baking sheet. Repeat until the mixture is all used up.
Space them out evenly across your prepared baking sheet and bake for 18-20 minutes or until lightly browned and completely cooked.
Sprinkle with parsley and serve.
