Yes
They do have custard cakes premade in the freezer. If you are looking for a specific one I would call ahead and see when they can have one available
It's been a while. I don't know if they sell them.
I'm not sure, l think they just sell the sundaes, floats, and cones. They may take orders for advanced sales of cakes. Try calling and asking for details on how to get a cake.
