Search for “cherry streusel bar” recipes. Lots of good options and one of the reasons we keep frozen cherries stocked!
A Cook’s Country one we prefer calls for cherry preserves too. Lidl’s version is an excellent value. The one at “Butter & Baggage” happens to be exact (without the attribution

which I sincerely believe to be CC). Some recipes call for cherry pie filling (don’t do it!) or are for 8/9” square pan (not enough for our household!).
