What dessert "Makes your eyes light up, your tummy say 'Howdy'"?

I'd love to meet the people that think up these slogans. And the poor so-and-sos that pay them for them....

In 1946 Dinah Shore did a cover version of the song "Shoo-Fly Pie and Apple Pan Dowdy" reaching the top-ten for the first time!

This is a line from a song, not an advertising slogan. The song says they're from New England, but I associate them with Mennonites, since the people I know who make them are Mennonites and the recipes are in a Mennonite cookbook we have. (Some would say Amish or Pennsylvania Dutch; I'm not getting into distinguishing among the three!) Some sites say the recipes date from "colonial times," which could be construed to mean New England, but I take to mean Pennsylvania.

This article is about the "plain people" and mentions both dishes.

"Shoofly pie has a supporting crust under a moist base (cookbooks and menus sometimes call it a 'wet bottom') of molasses, brown sugar and spices that is topped with a crumbly mixture of brown sugar, flour and shortening; shoofly can be moister or dryer, depending upon the proportion of moist base to crumbly top. ....and apple pandowdy is apple cobbler."

Cynical Bear assumed that it must be a slogan...
In the UK, the 'pie' would be classed as a 'tart'. Our pies tend to have roofs. Sounds nice - but we have another communication problem. The 'pie' sounds a bit like our treacle tart https://en.wikipedia.org/wiki/Treacle_tart which is made with golden syrup not treacle (we know what it is....) - but I'm not sure what your molasses are. Ours is even thicker than treacle - when a very large tank of it split and covered a nearby road, it took hours and hours to free the stuck cars. (I hate to think what it did to the drains.)
