Preheat your oven to 375°F (190°C) and line a large baking sheet with parchment paper.
In a spacious mixing bowl, combine the breakfast sausage, Bisquick mix, shredded cheese, minced green onions, garlic powder, onion powder, black pepper, and cayenne pepper (if desired). Mix thoroughly until fully incorporated.
Gradually pour in the milk, mixing with your hands until the dough comes together. It should feel slightly moist but not excessively sticky.
Take small portions of the dough and roll them into balls approximately 1 inch in diameter. Arrange them on the prepared baking sheet with space between each ball.
Bake in the preheated oven for 18-20 minutes or until golden brown and cooked through, checking that the internal temperature reaches 160°F (71°C).
Allow the sausage balls to cool for a few minutes before serving.
Notes
Serve warm with spicy mustard or ranch dressing for dipping.
