Special Marshmallow Treats

This may not be the most exciting recipe, but it’s what I made today and I was pretty happy with the results. In an effort to use up what was left of a giant box of Special K and a bag of marshmallows I’d bought for no particular reason, I substituted Special K for the Rice Krispies in Rice Krispies Treats.

As mentioned, it’s not the most innovative thing in the world, but in the past the only Special K Bars I’d made were the ones with peanut butter and corn syrup.  Finding out that Special K works well in regular marshmallow type bars was kind of a revelation. I’d thought about it for a while, but had never actually tried it.

For those of you wondering what the measurements are, here’s the recipe.    I like them kind of stiff so I used about 6 cups of Special K, but for those of you who like a gooey bar, use a little less. My only complaint about these are that they don’t cut quite as neatly as Rice Krispies Treats.

Rice Krispies Treats made with Special K
Recipe type: Dessert
Cuisine: America
Serves: 12
  • 4 tablespoons unsalted butter
  • 1/8 teaspoon salt
  • 10.5 ounce bag of mini marshmallows
  • 1/2 teaspoon vanilla extract
  • 5 1/2 to 6 cups Special K
  1. Line a 9 inch square pan with nonstick foil. Alternatively, line with regular foil and spray with cooking spray.
  2. In a large (3 quart), preferably non-stick saucepan or a slightly larger pot, melt the butter over medium heat. When it's about halfway melted, add the salt and swirl it around.
  3. Add the marshmallows and stir over medium heat until they're about halfway melted, then reduce heat slightly and continue stirring until they are fully melted.
  4. Remove from heat and stir in the vanilla extract.
  5. Add the cereal (it will seem like a lot) and stir until fully mixed, then press into the pan and let cool completely.
  6. Lift from pan and cut into squares.
If you use salted butter, omit the salt. If you like a gooey and less stiff bar, use 5 cups of cereal instead of 6.

    I love the way you find uses for ingredients that are sitting around. I do the same thing – very little waste here. Speaking of Special K, today a co-worker shared some Special K Popcorn chips that taste like kettle corn. They’re really good & the calorie count is pretty reasonable – 120 calories for 28 chips. She said they’re in the cracker section.

    Martha, I got stuck in a long line at the grocery store and the lady next to me was buying those Special K chips. I asked her how they were and she said they were really, really, good and that she wanted to try all the flavors. I almost bought some today, then realized I didn’t need any chips.

    I have part of a box of Special K, but it’s the kind with chocolate chunks added. I’m sure that would still work! 🙂 I also just recently bought some of the mallows with Halloween shapes, like ghosts, bats, pumpkins. That would make a nice gray colored crispy treat. I need to just go through my baking cupboards and make a crazy crispy treat because there seems to be lots of things to get rid of. Like part of a bag of the Birthday Cake Oreos that the kids don’t really like the taste of.

    Oh, I have been trying to figure out something to make for the developmentally disabled adults I work with for Halloween. I have chocolate coco puff cereal and candy corn, so I think I’ll do Chocolate “rice krispy” treats for them. Thanks for the idea! LOL

    Perfect! I staring down the remains of 2 (why can’t they finish one before opening the other?) boxes of Special K. And just in time for sleepover round two. Thanks!

    I used chocolate krispy cereal to make a Halloween treat. Then I added candy corn on top of each bar. I tred to make it look like a Jack-o-lantern face but the pieces weren’t big enough to use enough of the candy corn’s to really be effective. Never-the-less, the color contrasts were quite Halloweeny.
    I don’t think it needed the vanilla since this was chocolate cereal but I added it anyway. I added about a tablespoon more of butter and then about a half cup more of marshmallows since I really like the creamy version of bars best. It turned out great. I do have to admit though, my older adult tastes have gotten away from this kind of bar!
