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.

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.
