I'm not sure if this is the right place to post, but it didn't seem to fit anywhere. Has anyone tried to make the Gingerbread Salted Caramel Buttercream Cookie Sandwich from Karamell-Küche with any level of success? We had a few while we were down there, and I'm dying to make some here for my staff at work, but I have no idea where to start. A quick google search didn't turn up anything really helpful. Thanks!
