These buttery cherry crumble bars are little slices of heaven, that's what they are. The shortbread base is everything shortbread should be - rich, not too sweet, and so tender it melts in your mouth.
Cool the bars for at least an hour before cutting into squares, or scoop them out with a spoon while they are warm. The bars will keep in an airtight container in the refrigerator for up to 3 days.
