Prep: In a shallow glass bowl, melt the butter in the microwave on reduced power to prevent splattering. In another shallow bowl, mix the sugar and cinnamon.
Cut: Using a pair of kitchen shears, cut each biscuit into thirds and set pieces on a plate, separating them so they don’t stick together.
Coat: Spray the bottom and the sides of an 8×8 baking dish well with cooking spray and preheat the oven to 375°F. Using an assembly line method, dip one biscuit piece in the butter, then coat it with the cinnamon-sugar mixture, and place it in the prepared dish. Continue the process until all pieces are coated and arranged in the pan.
Bake: Bake biscuit bites for about 15-18 minutes or until deep golden brown on top. Allow them to cool for a few minutes before serving.
For the Icing: Stir together confectioners’ sugar, milk, and vanilla extract. Drizzle over baked biscuit bites.
