How many thicknesses of unleavened cakes are mentioned?

Answer From The Annual Reading Schedule - Week 23 Notes For Leviticus: At least Two – the regular unleavened cakes but also the unleavened wafers/thin cakes (Leviticus 2:4). It is possible there were more, but we at least see these two thicknesses. We researched online before and found that it may have been the normal unleavened bread was an inch or more in thickness. The store-bought matzah crackers are probably not at all like the unleavened bread back then.
