Nestle Toffee Cookies not working?

Hello! I tried to make cookies with caramel chip Nestle Toll House recipe chocolate cookies … Replacing just butterscotch chips for chocolate chips. Cookies Bake Just Will not right! They become too thin during the cooking and get too dark on the bottom while the tops are still doughy. What am I doing wrong? Thank you in advance for the help!

Sure that baking soda is fresh, try using parchment paper to line your cookie sheet (I use a baking pan silicone liner It is reusable and they keep the cookies from burning or sticking) Put your oven rack above the oven does not bake cookies on the lower rack (less hotter). I use this recipe all the time and I used to cook them longer than the time he said, because they would feel soft and then when they cooled they would be too hard. cookies will be soft when they are warm and strengthen as it cools. that's all I could think, but the type of chips you use does not matter
