Simple No-Bake Pumpkin Spice Marshmallow Cereal Treats

by | Oct 21, 2021 | Recipes

Pumpkin Spice Marshmallow Cereal Treats are a super simple riff on the classic Kellogg’s Rice Krispies Treat. This recipe uses new seasonal and limited edition items Pumpkin Spice Cheerios and Jet-Puffed Pumpkin Spice Marshmallows. The marshmallows are melted with butter and a generous addition of pumpkin pie spice to amplify the bold combination of warming spices that we all know and love!

So, I recently bought a box of limited edition Pumpkin Spice Cheerios while at the grocery store to try out and review. I’m a sucker for all things pumpkin spice. So it wasn’t any surprise that out of an entire display of seasonally flavored items, I chose the pumpkin spice one.

I’m not big on cereal, even though these Cheerios were tasty. I knew that I wouldn’t get through the whole box before they went stale. So, I decided to take them for a spin with the ageless favorited recipe for Rice Krispies treats. Let me tell you—using a cereal that isn’t a flake or krispies with the original rice krispies recipe turns out a less desirable marshmallow cereal treat result.

BUT, with some tweaks here and there, I was able to make pumpkin spice marshmallow cereal treats that are brimming with the bold, warming spices that we know and love in all of our pumpkin spice favorites. And it’s just as quick and easy as the original!

Pumpkin Spice Marshmallow Cereal Treats

I knew that I wanted to turn the Pumpkin Spice Cheerios into marshmallow cereal treats that amplify the pumpkin spice flavor. I first figured that I could just add some pumpkin pie spice to the already called for marshmallows. The first batch was tasty. But, it was quickly apparent that when using a cereal other than rice krispies or, say, corn flakes, the amount of marshmallows the traditional recipe calls for doesn’t produce the same signature gooey, sticky result.

So it was time to do a little experimenting. As I was playing around with this pumpkin spice marshmallow cereal treats recipe, I came across Jet-Puffed’s Pumpkin Spice marshmallows. At the time, I wasn’t thinking about using them in these marshmallow cereal bars; I just have someone in my circle who loves eating marshmallows as a snack, so I happened to see these.

But, as luck would have it, the marshmallows themselves were tasty. But, just like the Pumpkin Spice Cheerios, they didn’t deliver the full-on pumpkin spice effect expected. So it only made sense to use them in this recipe for marshmallow cereal treats. If anything, them already being of the pumpkin spice variety would only lend more pumpkin spice flavor. And would ensure that I didn’t have to solely rely on pumpkin pie spice.

Melting Pumpkin Pie Spice in with the Butter is Key

Warming spices like the ones in pumpkin pie spice (cinnamon, clove, nutmeg, and ginger) are the kind that do best when given a chance to “bloom”. To help a spice bloom, heat is used to bring out the natural oils that carry its flavor. Blooming is done through two primary methods. The first is when you toast the spices in a dry skillet over low heat until they’re aromatic. The second method is to heat the spices through in a fat like butter or olive oil.

Both of these methods help to release and extract the flavor from the spices. With this pumpkin spice marshmallow cereal treats recipe, I bloomed the pumpkin pie spice in the butter as it melted. So as the marshmallows melted and incorporated with the spiced butter, the pumpkin pie spice was blended throughout the marshmallow creme that would be added to the cereal.

What resulted was an intense, but balanced, pumpkin spice flavor that is sweet and spicy. It’s bold and fully infused throughout these ooey, gooey, satisfyingly sticky marshmallow cereal treats. If you love Rice Krispies treats and pumpkin spice, you’re going to totally dig these super simple no-bake pumpkin spice marshmallow cereal treats!

Ingredients For Pumpkin Spice Marshmallow Cereal Treats

overhead shot of ingredients to make the pumpkin spice marshmallow cereal bars
  • Pumpkin Spice Cheerios – These limited edition little o’s make up the body of these pumpkin spice marshmallow cereal bars. They also subtly add a traditional pumpkin flavor.
  • Jet-Puffed Pumpkin Spice Marshmallows – The pumpkin shaped seasonal flavored marshmallows get melted down into a thick, sweet creme. That creme envelops the Cheerios and binds them together. Their flavor has a hint of pumpkin spice that gets intensified with the addition of some pumpkin pie spice blend.
  • Pumpkin Pie Spice – When used sparingly, this spice blend adds some coziness to a recipe. But for this recipe, we’re pumping up the volume on flavor and add in an entire tablespoon of this magic! We’re looking for in-your-face pumpkin spice, not some milquetoast version, and that’s what we get with this ample-sized addition.
  • Butter – Melted butter helps to bloom the pumpkin pie spice. It infuses the warm, spicy pumpkin spice flavor throughout the marshmallows as they melt.

Ingredient Swaps & Variations

  • Make Them Decadent! – Want to put these pumpkin spice marshmallow cereal treats over the top? Melt down your favorite kind of chocolate and drizzle it over the top for a rich, sweet treat that delights the appetite and the eyes.
  • Dial Back the Flavor! – If you like pumpkin spice, but aren’t into the slap-your-mama boldness of the pumpkin spice level in this recipe, no worries. There’s two ways you can dial back the boldness. First, try reducing the pumpkin pie spice to half of what is called for in the recipe card (see bottom of post). If it’s still too much kick for your taste, then swap out the pumpkin spice marshmallows for regular marshmallows and that should do the trick.

Recipe Tips & Tricks

What to Remember – Keep stirring! When making the marshmallow creme from scratch, it always seems to take forever. But these Jet-Puffed Pumpkin Spice Marshmallows do seem to take a little longer to fully melt down than your typical marshmallows. Just keep stirring and eventually they will melt down into a thick, velvety smooth creme.

What to Avoid – Work quickly once your marshmallow creme is ready to ensure that the cereal treat mixture doesn’t set up before you’ve fully incorporated the marshmallow creme. I find that a sturdy wooden spoon, a silicon blade spatula, or a metal spoon work best for mixing the creme into the cereal. Also, when pressing the marshmallow cereal treat mixture into your baking dish or pan, use a piece of parchment paper to help press the mixture into the dish; this will help ensure the mixture doesn’t stick to your hands. If you don’t have parchment paper, you can just put a drop or two of oil on your hands and spread it around to coat them before pressing the cereal down.

Frequently Asked Questions

I don’t have pumpkin pie spice on hand. Can I make my own at home?

Sure! There are lots of recipes online for making a pumpkin pie spice blend at home. Most include cinnamon, nutmeg, clove, and ginger.

I like pumpkin spice, but this looks a bit intense. Could I just use regular marshmallows instead?

Absolutely! This recipe calls for one bag of the pumpkin spice kind and the bag is 8 oz. You can easily swap it out for one 10 oz bag of regular mini marshmallows and come out with a very similar result.

I can’t find the pumpkin spice Cheerios. Can I use a different cereal instead?

You totally can! You can sub in whatever cereal your heart and tastebuds desire. If the cereal is shaped similar to Cheerios, you’ll end up with a similar ratio of cereal to marshmallow if you use the amount of cereal called for in the recipe card (see bottom of post). If the cereal you choose is smaller or bigger, you’ll come out with different ratios. Smaller cereal will mean more marshmallow; bigger cereal will mean less marshmallow. So just keep that in mind when you choose your alternate cereal to use.
