These might be the problem. They are cooling on the counter.
I was seven or eight when I tried my first rugelach. We lived in Atlanta at the time, and a store called Harry's Farmers Market (looks like Whole Foods owns it now!) was in the regular grocery rotation. In my memory it was part warehouse, part gourmet food shop, with a labyrinth of aisles holding special local and imported items. Mom did a lot of baking when we were kids, but one of the few things she bought were their housemade chocolate rugelach cookies.
Rugelach are my very favorite cookie, for eating and for baking. They are the poster child for easy to make with huge wow factor baked goods. I make them often, and never the same filling twice.
