The crackers are completely covered in toffee and look like flaky pie crust when bitten into. If you are making a smaller pan, definitely reduce the amount of butter and sugar. The recipe says about 40 crackers and that was my largest cookie sheet so adjust according to the number of crackers you use. No need for more toffee. It is very rich. Truly a butter toffee similar but better than Werther's hard caramels.
