Preheat the oven to 400 degrees F while you are preparing your other ingredients.
In a baking pan, line the sheet and add saltine crackers. It should be just one layer.
While you are doing that, you can add butter and sugar to a saucepan and heat it for 3 minutes. Now pour this amazing caramel on the top of the crackers.
Make sure that it is covered completely. Bake it for 5-7 minutes and then add a layer of chocolate chips on the top. Let it be at room temperature and soon the chocolate will melt. Spread the chocolate with the help of a spatula and then add the pecans to the top as this recipe topping. Put it in the fridge for 30-40 minutes and then you can cut it into your required size of toffee.
