this is very similar to what we call Chikki... a sweet treat in western india... readily available in Bombay / Mumbai... and also in indian stores here in the US... u can use
jaggery... other kinds of sugar... or even some honey to mix in the syrup... for the nuts u can use cashews, almonds, seasme seeds instead or in combination with peanuts... u could try experimenting with different layers of thickness... and even try a mould that would make it look
more like a hersheys bar... easier to break off without creating too many crumbles
