Preheat the oven to 400° and spray the muffin tin with non-stick spray.

Fry the sausage to a light brown to cook off most of the fat. Break up the meat as it cooks. While this is cooking, you can start prepping the other ingredients--just keep an eye on it!

Into a large mixing bowl, add: the baking mix, milk, shredded cheddar cheese, and egg. Mix well, ensuring you break up any clumps of the baking mix.

Drain the excess grease off the lightly browned sausage and give it a quick stir in with the other ingredients.

Spoon 24 equally sized portions of the sausage biscuit mixture into the wells of the muffin tin. Set the oven timer for 25 minutes. They will be nicely browned with delicious melted cheese at the end of 25 minutes. Remove them from the tin immediately.
