Food & Candy in a Pseudo-Medieval-Inspired World

[Silverscale]

You mention coffee, cacao, and Vanilla. If you take a look at Arm's and Equipment guide you will find a whole list of various food stuffs from meats to spices to beverages and appropriate prices for each in a medieval setting.

As for ice cream... how about

Create Frozen Confection:
Conjuration (?)
Level: Scor/Wis 1
Components: V,S,M
Casting Time: Standard Action
Duration: Instantaneous
Target: Ingredients

With a wave of your hands and a few simple words, the ingredients before you swirl together and after a few moments, you are holding an ice-cream cone with your favorite flavor ice-cream on top.

This spell can be used to create any sort of frozen desert you desire as long as you have most of the ingredients available.
(read there are actually quite a few ingredients in ice-cream and it would be silly to make sure your player has every last one of them)

Material Component: The ingredients for the desired confection.
