I make these easy caramel squares all the time for school cake sales and Christmas food gifts. You can adjust each section to make each layer as thick as you like.
Reduced butter in caramel to 4 tablespoons after reading other reviews. - 15 Sep 2015 (Review from Allrecipes AU | NZ)
I will make it with double the caremel next time, but think that is a preference thing. Worked out great and easier than I thought. - 15 Jan 2014 (Review from Allrecipes AU | NZ)
