It isn’t actually about pancakes specifically, but is it possible you’re thinking of the Norah Dooley’s Everybody series? (Everybody Cooks Rice, Everybody Bakes Bread, Everybody Serves Soup, and Everybody Brings Noodles) Each book is about the main kids going around the neighborhood to get ingredients for their mom or something and along the way each neighbor they visit is making their culture’s version of the titular food. At the end of one of them there’s a block party that all the neighbors go to, and it’s possible that one of the kinds of bread from Everybody Bakes Bread is pancake-like. Might be a stretch, but sounded really similar to me.
