Preheat the oven to 375°F and spray a 12-cup muffin pan with nonstick baking spray (I like the kind with flour in it.)
Remove the biscuits from their packaging and place them on a parchment-lined surface (or other nonstick surface). Roll them out to a 3-inch diameter.
Sprinkle 1 1/2 teaspoons of cinnamon over the biscuits (on both sides). You’re using one 1 1/2 teaspoons total for all of the biscuits (you can add more if preferred.)
Place the rounds in the prepared muffin pan, pressing the bottom and sides of the dough to fit the pan.
Bake in the oven for 6-8 minutes until golden brown and the base of the dough is cooked.
Working quickly and while the dough is still soft, use the bottom of a shot glass to shape the dough to create a cup shape. Set aside.
Place 3 medium Granny Smith apples, peeled and diced small in a large skillet. Add ¼ cup granulated sugar, ¼ cup packed light brown sugar and 4 teaspoons fresh lemon juice and cook the apples over medium heat, stirring until the sugars have dissolved.
Add the remaining 1 teaspoon cinnamon, ¼ teaspoon ground nutmeg and ¼ teaspoon salt, stirring to combine.
Sprinkle in 4 teaspoons all-purpose flour and cook for 1 to 2 minutes or until the mixture starts to thicken.
Spoon the apple mixture evenly among the 10 pie cups. Set aside.
Combine 1 cup powdered sugar and 2 Tablespoons milk in a small bowl, whisking to remove any clumps. Spoon the glaze over the cinnamon rolls.
Serve while still warm.
