Whatchamacallit Krispie Treats

Whatchamacallit Krispie Treats - by Glorious Treats

Rice Krispie Treats are one of those desserts I don’t think I’ll ever get tired of.  The original recipe is delicious on it’s own, but I really love how many amazingly delicious variations there are to think up!  I’ve made lots of yummy and fun Rice Krispie Treat variations before, but this chocolate, caramel and peanut butter version is going to be added to my list of favorites!

If you’re curious about the name, these Whatchamacallit Krispie Treats were inspired by the Whatchamacallit candy bar.  A Whatchamacallit candy bar is a “peanut flavored crisp with a layer of caramel, and covered in milk chocolate.”  These Whatchamacallit Krispie Treats have all the same flavors and textures of the delicious candy bar…. and you can make them at home anytime you want!   In fact, I like this Krispie Treat version even better than the candy bar!

Chocolate Caramel Peanut Butter Krispie Treats (a.k.a. Whatchamacallit Krispie Treats)

Yield: One 9"x13" pan (about 24 servings)

Rich and delicious Rice Krispie Treats inspired by the Whatchamacallit candy bar.


7 cups Rice Krispies cereal
8 cups mini marshmallows
4 Tablespoons Challenge butter
1/3 cup peanut butter

1 bag (11oz.) caramel bits
2 Tablespoons milk
1 1/4 cup semi-sweet chocolate chips


Prepare a 9"x13" baking pan by spraying lightly with non-stick cooking spray, and set aside.

Get two very large bowls. Into one bowl, add the rice cereal, and set aside.
Into the other bowl, add mini marshmallows and butter. Microwave for 2-4 minutes, or until the marshmallows are very soft and puffy.
While the marshmallows melt, measure out the 1/3 cup peanut butter and set aside.
Carefully remove the bowl of marshmallows from the microwave and stir until the (now melted) butter is incorporated.
Working quickly, add 1/3 cup peanut butter to melted marshmallows and stir.
Pour the peanut butter/marshmallow mixture over the bowl of rice cereal and use a rubber spatula (sprayed with non-stick spray) to quickly stir and combine the ingredients.
As soon as the cereal has been coated with the mixture, pour/scoop the rice krispies mixture into the prepared pan.
Use the spatula to press the mixture into the pan and flatten and even out as needed. Set aside to cool.

While the treats cool, in a small saucepan add caramel bits and milk.
Heat over medium heat until melted, stirring as needed.
Pour melted caramel over rice krispie treats, as evenly as possible.

In a small bowl, add chocolate chips and melt at 50% power in the microwave until almost melted (in 30 second intervals). Stir until melted and smooth.
Pour chocolate over caramel layer, using an offset spatula to spread, as needed.

Allow to cool about 30 minutes before cutting.

Store treats covered and in a cool place (on the counter) up to two days.

Notes- If you can not find the caramel bits (usually sold near chocolate chips), feel free to use individually wrapped caramels (such as Brachs).

For the peanut butter, I used natural peanut butter (with no added sugar).

  5. Funny story- I was a preteen. Proud to be finally babysitting “on my own.” There was a Whatchmacallit in the fridge for me but it was way to hard to chew so I put it in the microwave….foil wrapper and all. Yeah. Scared the BEJESUS out of me!

  17. Hi

    If I use regular old skippy peanut butter instead of natrual will be too sweet.

  18. I love your site. Great recipes. Could you change your font color though. I cannot read it to save my life. It’s so faint. It’s almost white, which makes it hard to read for most people, I’m sure. Thanks!

  19. Hi Glory – can you substitute the peanut butter with something else? I am thinking that these could be good for school treats when required. Many thanks Leanne

  20. And, you really think they will last 2 weeks on anyone’s counters!

  21. OMG… these look and sound amazing. I’m off to check the birthday calendar to see who I can use as an excuse to make some (and give most away or I’ll eat them all).


  22. Can these be frozen? If so, do they hold up?

  23. These were really good, but didn’t taste like the
    Whatchamacallit candy bar. There’s way too much Krispy treat compared to the caramel and chocolate. I could barely taste the peanut butter, the caramel layer was way too thin so it got lost in the huge amount of krispy treat and chocolate. The chocolate layer was super thick and not simply a chocolate covering like you’d find on a candy bar. I realize that this isn’t a true copycat Whatchamacallit recipe, but I still expected it to be similar to the candy bar simply because of the recipe title.

    This recipe needs to have more peanut butter, less crisp rice cereal, more caramel, and less chocolate. It should also be poured into a rimmed baking sheet or a dish that’s larger than a 9×13 so that the bars can be pressed down thinner and maybe with all these changes these bars would be much closer to a Whatchamacallit. Thanks for the recipe though, the treats were still delicious!

    • Yes, these are Krispy Treats that are inspired by the flavors of a Whatchamacallit, they are not intended to be a true replica of the candy bar itself. Sorry if you had different expectations than that. Feel free to adjust the recipe as you wish.
