Beat together the butter and sugars until light and fluffy. Beat in the caramel sauce, eggs and vanilla extract. In a separate bowl, whisk together the flour, salt and baking soda. Slowly add to wet ingredients. Stir in the white chocolate pieces.
Refrigerate dough for at least 2 hours. Scoop out cookies and place on a parchment lined baking sheet. Press down slightly and sprinkle with a pinch or two of salt. Bake for 12-15 minutes or until just slightly golden.
