wonder if it was butter rolls. Biscuit dough spread in the pan or rolled up and sliced like cinnamon rolls, then baked in a sauce of milk and sugar. The sauce gets thick almost like a pouring custard. I will look for the recipe, my grandmother used to make it when I was young and I may have her recipe. You could try searching online for old fashioned butter rolls.
I think thats a version of it.
The butterbread desert I’ve had isn’t rolled like cinnamon rolls tho.
