1. Heat oven to 400 degrees. Cream together butter (at room temp) and sugars, then add eggs one at a time.
2. Combine flour, cream of tartar, baking soda and 1/4 teaspoon salt, then add this to the butter mixture. Using a small cookie scoop or a table spoon scoop out dough into a ball, flatten slightly then add a caramel (cut in half if they are really big). Sprinkle the caramel with sea salt, top with more dough, roll the dough around the caramel into a ball.
3. Combine the 2 tablespoons sugar and 2 teaspoons cinnamon with 1/4 teaspoon sea salt then roll the balls into the sugar/ cinnamon mixture.
4. Place balls 2 inches apart on a baking sheet and bake for 8-10 minutes.
