These low fat Rice Krispie Treats taste just like the good old Rice Krispie Treats you make on the stove top. The real “treat” is that there’s a lot less mess!
And these crispy rice treats don’t need your undivided attention to prevent scorching, either – since they are made in a crock pot!

This will be my go-to way to make Rice Krispie treats from now on.
One of my Nana’s favorite things to make, she would have loved how easy these Crock Pot Rice Krispie Treats are to make too.

Okay, so now I remember – I was looking up Rice Krispy treat WW PP. ha, this is where it took me. Thanks!
Ah, this is great! Thank you. I hate stove top cooking and went to the store to buy the ingredients to make Rice Krispy nests for Easter. I haven’t a clue why I even happened upon your post but am so thankful! Going to start everything now in my crockpot! Thank you!!! Who knew?
I’m a little confused. After you cook the mixture in a crock pot, stir it, then add it to the pan, isn’t it done? It says at the end there to “Let cook and cut into 12 bars.” after it says to put it in the pan. Is there more cooking to be done after the crock pot…? Thanks!
Hi Lacee,
Sorry for the confusion. It was a typo that should have set “let COOL and cut into 12 bars.” I’ve fixed the post. Thanks for letting me know.
When transferring the mixture to the prepared pan, using a sheet of wax paper to pat it into place is easy.
What would be your thoughts on adding chocolate chips into these rice krispie treats? Would they be able to withstand melting the slow cooker? Thanks!
Hi Julie, I’m afraid the chocolate would not stand all the time in the slow cooker. You might be able to add them right at the end.
