I have no idea what a Spanish Bar Cake is. My early memories of the A&P were their brand name “Ann Page” and that they sold encyclopedias as the end of the checkout! They still have the 8 o’clock coffee with the grinder at checkout.
We used to miss Ebinger cakes. They brought it back in its traditional mint-green box but didn’t sell well, unfortunately.
I have never heard of Ebinger cakes. Where are they located?
