In a large mixing bowl, mix together flour, sugar, salt and baking powder. In a smaller bowl, whisk together buttermilk and egg.
Add egg mix to flour mix and thoroughly combine. Then add in grated butter and combine.
In a frying pan over medium high heat, cook sausages for about 8 minutes, turning for even cooking. Remove from heat and then cut into ½ inch pieces.
Add cut sausage, apples, cheese and remaining seasonings to a bowl and toss to coat. Then fold mixture into biscuit dough.
Use a ⅔ cup scoop (#6) to form dough into 12 biscuits and line them out on a parchment paper covered baking sheet. Bake for 18-20 minutes. Let rest for at least 5 minutes before serving. Drizzle with maple syrup, if desired.
