Make the topping by mixing the sugar and cinnamon together. Set aside.
Cream the butter and sugar together until fluffy (1-2 minutes) with an electric mixer. Mix in the egg and vanilla and set aside.
In another bowl, whisk together the flour, cream of tartar, baking soda, cinnamon and salt. Slowly add the dry ingredients to the wet ingredients and mix together on low until well combined.
Stir in the apples until well combined.
Using a cookie scoop, scoop out the dough and flatten it a little bit with your fingers. Flatten one of the caramels a little and place on top of the dough. Then mold the dough around the caramel and roll into a ball.
Place each ball of dough into the topping mixture and roll around until well coated. Place the cookie dough balls onto a greased cookie sheet. Bake at 350 for about 10-11 minutes or until the cookies are very lightly browned. Cool for at least 15-20 minutes on the baking sheets before you try to move them to a wire rack so that the cookies don't fall apart! Or you can eat them warm with a spoon. And some vanilla ice cream. ;)
