*Saltine alternative: Five sheets of matzo squares offer a worthy alternative to the saltines. You will have to break one of the sheets to make your rectangle.
*For a gluten-free cookie: Look for a GF alternative to the classic saltines or opt for 5 sheets of gluten-free matzo bark. I’ve tested the latter with good results.
**Nestle semi-sweet morsels work well. I find the minis don’t tend to melt as smoothly. Dark or milk chocolate chips may be substituted, as can chopped baking chocolate. Hershey Bars offer yet another option.
Storage: Keep in an airtight container in the fridge for up to a week. The bark also freezes very well.
