Cut the apple into small pieces.
Add the apple to a small pan with cinnamon and a small splash of water.
Cook over medium heat for a few minutes until the apple becomes soft and slightly saucy. Add a little more water if needed.
Add 2 tablespoons of the cinnamon apples to the bottom of a serving glass.
Spoon 2 tablespoons of low fat Greek yogurt on top.
Crumble 1 Biscoff cookie over the yogurt.
For the optional Biscoff layer, mix 1 tablespoon Greek yogurt, 1 tablespoon cinnamon apples, 1 teaspoon Biscoff spread, and 1 crumbled Biscoff cookie.
Spoon the mixture into the glass.
Top with another Biscoff cookie, a little cinnamon, and a few pieces of the cooked apples.
Serve immediately for the crunchiest texture.
