Creating Apple Pie à la Mode Ice Cream Sandwiches can be made simple by following these steps:

1. Preheat Oven: Preheat your oven to 350°F (175°C) and line your baking sheets with parchment paper.

2. Make the Cookie Dough:
– In a bowl, whisk together flour, baking soda, cinnamon, and salt.
– In a separate large bowl, cream the softened butter with brown sugar and granulated sugar until light and fluffy.
– Add the eggs one at a time, then the vanilla extract; mix until fully combined.
– Gradually add the flour mixture to the wet ingredients, mixing until a dough forms.

3. Prepare the Apple Filling:
– In a large mixing bowl, combine the diced apples, granulated sugar, cinnamon, lemon juice, and cornstarch.
– Stir until the apples are well coated and the mixture is evenly blended.

4. Bake the Cookies:
– Scoop tablespoon-sized portions of dough onto the prepared baking sheets, leaving space for spreading.
– Use your thumb or the back of a spoon to create a small indentation in the center of each cookie.
– Fill each indentation with the apple filling mixture.
– Bake for 12-15 minutes until golden brown. Remove from the oven and allow to cool on a wire rack for about 10 minutes.

5. Assemble the Ice Cream Sandwiches:
– Once the cookies have cooled slightly, take a cookie and place a generous scoop of vanilla ice cream on the apple-filled side.
– Top it with another cookie, apple side down, to form a sandwich.
– If desired, drizzle with caramel sauce before serving.
