Preheat the oven to 375°F (190°C) and line a baking sheet with parchment paper.
In a large bowl, whisk together flour, salt, pepper, onion powder, and baking powder.
Add grated cheddar cheese, ground sausage, and melted butter, then mix until well combined.
Pour in milk and mix until the dough comes together (it should be slightly sticky).
Roll the mixture into 1-inch balls and place them on the baking sheet.
Bake for 18-20 minutes, or until golden brown and fully cooked.
Let them cool for a few minutes before serving.
Enjoy warm with your favorite dips or sauces!
