Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
In a bowl, whisk together the self-rising flour and cinnamon.
In the same bowl add in your melted butter, applesauce, and diced apple. Mix until just combined.
Using a spoon, cookie scoop, or your hands, drop spoonfuls of the dough onto the prepared baking sheet, shaping them into rounds.
Bake for 13-15 minutes, or until the biscuits are golden brown.
Allow to cool slightly before serving. Enjoy!
