Notes
Type of Apples: Use firm and slightly tart apples, like Granny Smith or Honeycrisp, for a better balance of flavors and texture.
Preparing the Filling: If you prefer a softer filling, you can cook the apples for a few additional minutes. Just make sure they don't completely fall apart.
Handling the Dough: Keep the dough refrigerated until you're ready to use it. This makes it easier to handle and helps the cookies maintain their shape during baking.
Cutting the Strips for the Lattice: For a more uniform and attractive lattice, use a ruler to measure and cut the dough strips.
Alternative for Brushing: If you don't want to use egg, you can brush the cookies with milk or cream to achieve a similar golden finish.
Flavor Variety: Adding a pinch of ground cloves or ginger to the filling can give it a different and more complex flavor.
Storage: The cookies can be stored in an airtight container at room temperature for up to 3 days. To keep them fresh for longer, you can refrigerate them.
Reheating: If you want to enjoy the cookies warm, reheat them in the oven at 300°F (150°C) for a few minutes before serving.
Serving: Serve the Apple Pie Cookies with a scoop of vanilla ice cream or some whipped cream for an even more delicious dessert.
