Looking For Recipe For Swiss Tart?

Does anyone know of a recipe for a little cake called a Swiss Tart? I had it years ago in a big cook book (now long gone). I've Googled, but the only ones I can find are for things called Swiss Chard tart. Not the same thing.

These were baked in paper patty pans. They were very crisp and 'short' tasting, and consisted of few ingredients, confectioners sugar, I think, custard powder and butter-melted. There may have been something else. You put them in the patty pans in a swirly design, and when they were baked you add a little red jam, or half a preserved cherry to the top of each one. Anyone have this recipe? Thank you!
