Preheat oven to 375℉ and lightly spray a mini muffin tin with non-stick cooking spray. Use two mini muffin pans if available.
02 -
Unfold the puff pastry sheets and cut each sheet into 9 equal-sized squares. Press each square into the mini muffin tin cups, molding them to the cups. Dock the bottoms of the pastry with a fork. Bake for 7 minutes.

While the puff pastry bakes, sauté the apples with butter, brown sugar, cinnamon, nutmeg, and salt in a large non-stick pan over medium heat. Stir frequently until the apples are fork-tender, about 5-8 minutes.
04 -
Whisk the cornstarch and cold water together in a small bowl to create a slurry.
05 -
Once the apples are tender, stir in half of the cornstarch slurry. Cook, stirring constantly, for 1-2 minutes to thicken. Add more slurry if needed for desired consistency. Remove from heat and let cool—filling will thicken further as it cools.
06 -
Remove the baked puff pastry from the oven. Gently press down the puffed pastry with a teaspoon to create a well for the filling.
07 -
Fill each puff pastry cup with 1 heaping teaspoon of the apple filling. Bake for an additional 10-12 minutes, or until golden brown.
08 -
Cool the tarts in the pan for 3-5 minutes before transferring to a cooling rack. Once cooled, garnish with chopped pecans, caramel sauce, and whipped cream as desired. Serve warm or at room temperature.
