Coconut macaroon drizzled with chocolate from the Blue Ribbon Bakery.
I do have to admit, I had one of those and it was really good.
OP, is it all sugars, or just cane sugar, or have you noticed that it's corn based sugars (dextrose, or the syrups, or even high fructose corn syrups)? DH and DS cannot have corn once it's made into a syrup...though they can have dextrose and cane sugars just fine. Give DH an old fashioned soda made with cane sugar and his blood sugar goes up a bit, but he's fine. Give him a Coke with HFCS, and his blood sugar spikes high, he picks a fight, and passes out. It's a HUGE difference. DS gets violent and mean when he has those ingredients. So most of what poeple have mentioned are completely out, doesn't matter how good the things might be, for DH and DS...can't even have Uncrustables (HFCS and corn syrup) or a Dole Whip (mainly chemical ingredients, and sweetened/thickened with corn syrup solids). And many of the ice creams at Disney have corn syrup in them (or even HFCS), including the ice cream in the Mickey Bar! AUGH. (we go to DTD for Haagen Dasz for ice cream, as HD is safer than the brand Disney uses)
So if you've noticed that different types of sugars cause lesser reactions, you might peruse the ingredient lists (bakeries all have 'em!) and choose things that won't cause a huge reaction.
Anyway, their chocolate chip cookies, so far, have been safe for DH and DS, so that's their goodie of choice. I like those, but that macaroon (I do not know the ingredients, as I don't have the freaky reactions to those things, and I wasn't sharing it) was really really good!
