Preheat the oven to 350 F or 180 C. Line two baking trays with parchment paper (or just one, and then bake the cookies in two intervals).
In a bowl, combine the flour, spices, baking soda and salt- then set aside.
In another bowl, cream together the butter and sugar (or sugars).
When light and fluffy, add in the egg, vanilla and molasses until incorporated.
Fold in the flour in three batches. The dough should be quite thick.
Cover the bowl tightly with cling wrap and refrigerate for an hour.
Roll 2 tbsp sized balls in your fingers, then coat in 1/3 cup of sugar.
Bake cookies (2 inches apart) for exactly 8 minutes.
After 8 minutes, take the cookies out of the oven and gently press down with the back of a spoon or fork.
Put the cookies back into the oven for one more minute.
Cool completely, then transfer to a wire rack.
Place the caramel sauce in a piping bag and drizzle over the cookies. Enjoy!
