Preheat your oven to 350°F (175°C).
In a medium bowl, whisk together the flour, baking soda, salt, and cinnamon.
In a separate large bowl, cream together the softened butter, brown sugar, and granulated sugar until light and fluffy.
Add the egg and vanilla extract to the butter mixture, mixing until well combined.
Gradually mix in the dry ingredients until just combined.
Fold in the diced apples and caramel bits gently.
Scoop tablespoon-sized portions of dough onto a parchment-lined baking sheet.
Bake for 10-12 minutes or until the edges are golden brown.
Remove from the oven and let the cookies cool on the pan for 5 minutes before transferring to a wire rack.
