Rice Krispie Treat Milkshake

This Rice Krispie Treat Milkshake couldn’t be easier to make with only 4 ingredients. It’s a delicious marshmallow milkshake with a Krispie Treat crunch!

Rice 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.

DOYOUKNOWWHOIAM? So yeah.  It’s simple and perfect.

How to Make The Best Milkshake Ever

Literally just blend your Fluff, ice cream and milk together.

Then lastly pulse in some Krispie Cereal.

Pour it in your favorite glass and feel like a mad genius-scientist-smart person.

Oh yeah, and top it off with some whipped cream, marshmallows and more krispies.
Because duh.

    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.

  2. Maria Costadini

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

  3. Kate | Food Babbles

    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!!

    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.

    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!

  6. Rachel - A Southern Fairytale

    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
