Instructions
Bring apple cider to a boil in a medium sauce pot over medium-high heat. Lower the heat to medium and continue to cook the apple cider until it has reduced to 2 tablespoons, about 15 minutes.
Line an 8-inch baking pan with parchment paper and spray with cooking spray.
Combine the reduced apple cider with heavy cream, sugar, corn syrup, and butter in a medium saucepot. Bring to a boil over high heat, then reduce heat to medium and cook until a candy thermometer registers 248 degrees F. Remove from heat and stir in cinnamon, nutmeg, allspice, and ground ginger.
Carefully pour the caramel into the prepared baking pan and let cool completely. Once cooled, cut the caramel into ¾-inch squares.
Preheat oven to 375 degrees F.
Prepare the snickerdoodles. Cream together softened butter with sugar in a large mixing bowl until fluffy and pale in color, about 3-4 minutes. Add the eggs and beat until combined.
Combine the dry ingredients including flour, cream of tartar, baking soda, and salt. Add the dry ingredients to the butter mixture and stir until well-combined. Portion the dough into 24 balls. Make an indentation in the center and insert a caramel. Cover the caramel and shape cookie dough into a ball. Repeat with the remaining dough.
Make cinnamon sugar. Combine sugar with cinnamon in a medium bowl. Coat the cookie dough in the sugar cinnamon mixture and lay on a lined baking sheet. Chill the dough in the freezer for 15 minutes or in ther fridgerator for 30 minutes.
Arrange the cookies to fit about 6 on a baking sheet, leaving plenty of space in between the cookies. Bake for 8-10 minutes or until lightly golden brown. Let cool on the baking sheet for 1 minute. Transfer to wire rack and let cool completely.
Notes
You can make the caramels up to 5 days in advance.
