Krispie Treat Milkshake


Mind officially blown.

I can barely even type right now.

Because yes, that’s a Rice Krispie Treat Milkshake rawt thurrr.



I came across this recipe while working at my kiddo’s school book fair.  There was this whole book dedicated to “Copy Cat Desserts” from restaurants.

I mean, if I can make a Cinnabon at home, then I may never have to leave the house again!


So, while plotting my future of sweatpants and Cinnabon Frosting mustaches, I came across a recipe for this milkshake.

Apparently it was once served at Jack in the Box.

Who? What? When?


I haven’t been to a JITB in possibly 12 years, so it made sense how this little nugget of genius might have slipped through my brain cracks.

Anyway, it wasn’t even an option not to make it.



So yeah.  It’s simple and perfect.

This is so crazy!! I literally just said to myself the other day, “I wonder what would happen if you put rice krispie treats in a milkshake”. Now I know! What a cool idea to add marshmallow fluff!!

I’m not a big fast food eater but if I had know that this was at Jack in the Box and had any idea of one within driving distance I would have been there. This looks amazing!

Melissa @ Treats With a Twist

I’d go nuts over this…and then I’d start messing with it…
Toasting the topping mallows maybe? Chocolate sprinkles? Peanut butter chips? Ut oh, stop me now!

I’ve never had marshmallow fluff – and I do everything that I can to avoid JIB…so I can see how this escaped me. 🙂
However, this sounds like the perfect STAAR is finally over – GO HAVE FUN and then come home and go into a sugar yummy coma kind of treat 🙂

My kids will love you for this 😉 🙂 <3

For realsies? This is just INSANE. I’ve never had the pleasure of visiting a J in the B, but that’s probably a good thing since I’d never ever leave.
