The vending machines at work have been going through some product changes over the last few weeks, and I've found at least 4 different kinds of honey buns/cinnamon rolls. I always make sure to try any new product I find in the vending machines.
Big Texas Cinnamon Roll was the one we've generally had and the one I see most frequently. It's alright, but it's really lacking in icing and there isn't much cinnamon flavor. The icing is really solid, so it tends to fall off in chunks as you're eating it. I've got little bits of icing down between the keys on my keyboard because of that design flaw. It's really just a big lump of sweet bread. That said, it does have a pretty nice size.
This is one of the old go-tos that I used to eat in high school. I've only seen this one a handful of times lately (and it might be a different brand than this picture), but I really like it. You can't go wrong with an glazed honey bun. I always eat it at room temp, never microwave. Still, I prefer iced ones to glazed ones.
Speaking of iced honey buns, Mrs. Freshley KILLS it with this bad boy. This is one of my all-time favorite vending machine foods. Super moist and the icing coats the entire thing. Really messy to eat and my poor keyboard needs wiping down afterwards, but totally worth it.
Finally my absolute favorite vending machine pastry: Mrs. Freshley's Cinnamon Swirl Bun. This is the perfect combination of honey bun and cinnamon roll. It's got a great coating of glazed-style icing and it packs a cinnamon punch that is just delightful. A++ do recommend if you see it in a vending machine.
