Preheat the Oven: Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper for easy cleanup.
Combine the Ingredients: In a large mixing bowl, combine the ground sausage, shredded cheese, flour, baking powder, garlic powder, salt, and black pepper. Stir everything together until well mixed. Add milk and continue mixing until the dough holds together.
Form the Sausage Balls: Using your hands, form the mixture into small balls (about 1 inch in diameter). Place them on the prepared baking sheet, ensuring they are evenly spaced.
Bake the Sausage Balls: Bake in the preheated oven for 20-25 minutes, or until golden brown and cooked through. Check for doneness by cutting one open to ensure the center is no longer pink.
Serve and Enjoy: Once done, remove from the oven and let them cool for a few minutes. Serve hot with your favorite dipping sauce, or enjoy them on their own as a savory snack.
