The Homebakery's Cakeish Corner is a cute little supplement shop that you can use to add a bit of flair to a campaign. It's basically a shop with lots of consumable (ha!) magic item baked goods for your campaign.
The shop itself is a great opportunity for your players to engage in a bit of RP, and includes notes on how to RP the shopkeep and a d6 table of random shop events. There's also a floorplan of the shop, and statblocks for the shop's proprietor and pets (but if you fight them, you're a monster.)
There's a variety of 25 different magical baked goods. My favorites were the Roc Cake and the Falling Angel Cake!
Shops like these can be really useful to have on hand for when your players go shopping unexpectedly.
