I go to Wanda's fairly frequently, and I've tried a few of their pies and baked treats.
Pies: pumpkin and blueberry are amazing.
Cookies: the gluten free chocolate crinkle cookies are usually outstanding, but make sure to ask for a nice and soft one. I've bought one or two that were bizarrely hard and tasteless. When I pointed this out to the staff, they were happy to replace my cookie with a fresher one. The dulce de leche coconut (also gluten free) cookie is very sweet and has a nice chewy texture.
Ice cream: ordered this once and it was bland, filled with ice crystals and just not worth the money. If you want ice cream or gelato, go to Manic Coffee or the Big Scoop on College.
Gluten-free cupcakes: avoid! They are tasteless and hard. The buttercream is bland and way too oily for my taste.
