Preheat your oven to 375°F (190°C) and line a baking sheet with parchment paper or lightly grease it.
In a small bowl, mix the granulated sugar and cinnamon until well combined.
Separate the biscuit dough into individual biscuits and cut each into quarters to create bite-sized pieces.
Dip each biscuit piece into the melted butter to coat lightly, then roll in the cinnamon sugar mixture until fully covered.
Place the coated biscuit bites evenly spaced on the prepared baking sheet.
Bake in the preheated oven for 8-10 minutes, or until golden brown and puffed.
If a glaze is desired, mix powdered sugar, milk, and vanilla extract in a small bowl until smooth, adjusting consistency as needed. Drizzle over the biscuit bites once they have cooled slightly.
Serve warm and enjoy the sweet, cinnamon-filled treat!
Notes
For a richer flavor, try adding a pinch of nutmeg to the cinnamon sugar mixture.
