Make the cookie dough. Beat butter, add the brown sugar, cream, vanilla. Beat until combined, fluffy and light in color. Beat in the flour and salt until combined. Stir in the chocolate chips. Spread the cookie dough over the caramel layer gently with an offset spatula and yes, back into the freezer!
