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.

I’m going nuts right now! My kids are going to think I’m the coolest mom in the world when I make this for them.

May 2, 2013 10:10 am

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!!

May 2, 2013 10:47 am

I need this in my life. Now. Amazing!!

May 2, 2013 10:56 am

Oh my goodness!This is crazy, I’ve just sent this to my cousin to make as she loves marshmallow fluff and milkshakes – yum!

Wow! That looks decadent and amazing!

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!

May 2, 2013 1:07 pm

This is GENIUS. Definitely my type of milkshake!


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!

Sorry I can’t type because Im picking up the pieces of my blown mind!

May 2, 2013 7:45 pm

You’re kidding, right?!
I love how you break the rules.
Why shouldn’t a milk shake be crunchy & fun??

May 2, 2013 8:42 pm

Yum! Wish we had books like this at the book fair!

May 2, 2013 10:39 pm

That is so very brilliant!!

May 2, 2013 11:29 pm

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

This is quite possibly the sexiest milkshake I’ve ever seen!


JITB has the best oreo cookie shakes so I can only imagine how absolutely amazing this one is!! I mean marshmallow fluff in a milk shake?! Amaze Balls!


Thanks. Now my brain is leaking out my ear because this totally blows my mind. I may never be the same. Thank you for bringing this awesomeness into my life.

This looks RIDICULOUSLY good!!! WOW! I need this in my life ASAP. And I’m feeling pretty happy at the moment that I have Rice Krispies left over from the bake sale, ice cream AND the Fluff!!

May 4, 2013 8:23 pm

Shelly, this sounds heavenly! We have been into Rice Krispie treats lately, will have to try out the milkshake.

May 5, 2013 11:52 pm

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.


wow, I can totally have two for breakfast

May 14, 2013 7:04 am

Wow that looks like tasty. Usually I like drinking to smoothies very much. Because I have to interest for making it.
