Lamingtons?

Does anyone know where to get lamingtons in Chicago? TipsyCake apparently used to have them (I found my old comment related to buying a coupon via TwoBuckDuck, that was a blast from the past) but Tipsy is no longer. The Googles have not been helpful.

They're actually pretty easy to make. There are a million recipes online, and you can even use store-bought cake or cake mix. Then dip squares in chocolate and roll in coconut. Even in Australia, where they're sold everywhere, a lot of folks just make them at home.

Otherwise, there are places online that sell commercial lamington's from Australia (e.g., https://theaustralianfoodshop.com/)

But, alas, know of of no local stores that sell them.
