I used to go to Velvet Sky multiple times a week when I lived in the area. The staff is friendly, very understanding of celiac and my gluten free needs. Their cake is also the best I have ever had, gluten free or gluten full (pre diagnosis). My one complaint is they don't deliver, but I have made more than one trip to Jenkintown just for cupcakes. You will not be disappointed.
They take orders for gluten free desserts but it is no longer open for just stopping in
