Not a ‘bakery’ cake; but the old A&P grocery used to have something called a ‘Spanish Bar Cake’.
It was WONDERFUL. You can’t buy anything like it anymore in a store; but there are lots of ‘copycat’ recipes on the Internet:

My grandmother always had one of those from the A&P, which she called the tea store, in her kitchen.
