Preheat your oven to 375.
Combine the sugar and cinnamon in a small bowl. Place the cut biscuits in a larger bowl and toss most of the cinnamon sugar mix over them until completely covered. Save a little bit of the mix for dusting at the end.
Layer the biscuits in a small casserole dish. (Mine was 8x8) Bake for 20 minutes, until the biscuits have puffed and are cooked through.
In the meantime, whisk the butter and powdered sugar in a small bowl. It will look crumbly and pasty. Then add the milk and vanilla and keep whisking. Voila - icing! Taste that. UGH. I know.
Using a spatula or knife, spread the icing over the warm biscuits. Sprinkle the remaining cinnamon sugar mix on if you want!
Serve immediately, for crying out loud.
Serves 4!
