If you gave me a choice of a treat – so we’re not talking about a dessert like pumpkin delight or pumpkin crunch cake – but more a cookie or a bar – I would choose a homemade rice krispy treat every single time. Homemade rice krispie treats are my weakness.
When they’re good – the ones that are soft and a little gooey – rice krispy cereal treats are so good. And we’ve made these shaped rice krispy treats (the base for this recipe) dozens of times this year – and they’re good!
This is a fun Halloween version of that classic treat without having to do as much decoration as say these witch rice krispy treats (cute but more time intensive) or any of my favorite Disneyland Halloween treats.
It’s more about what you’re adding to the mixture so the treats are as easy as the classic! It’s those mix-ins that make these really fun treats for the fall season or even a great Halloween party snack for school!

Ingredients
Ingredient notes
- Butter – the butter combined with the mini marshmallows are what helps everything melt together smoothly. I recommend using salted butter for this recipe. If you only have unsalted butter, I recommend adding 1/4 tsp of salt to the recipe similar to what I did in these chocolate dipped rice krispie treats.
- Mini marshmallows – you’ll need to use mini marshmallows in this recipe or cut up larger marshmallows into smaller pieces with the way this recipe is written!
- Rice Krispy Cereal – make sure your cereal is fresh and crisp. Just like stale rice krispies aren’t great to eat as a bowl of cereal, they aren’t good in these treats.
- Festive sprinkles – any sort of Halloween sprinkles will work, but I really liked doing black and orange!
- Candy corn – while not really something I thin of as only Halloween candy, the candy corn in these is the perfect addition!
How to make Halloween Rice Krispy Treats
Okay now let’s get to actually making these fun Halloween rice krispie treats! If you’ve ever made homemade rice krispies, these will be very similar!
Start by lining a 9×13 inch baking dish with parchment paper. As a note, I actually halved the recipe for this post (so you’ll notice the pictures are in a square baking dish) but the recipe card is written for a 9×13 baking dish!
Tip!
You can make these in a non-stick baking dish without the parchment paper, but you won’t be able to get the same clean squares you see in my pictures. If you use parchment paper, you can simply grab the edges of it and pull the entire thing out when the treats are ready to go. Then just cut into perfect squares! I do this with everything from homemade brownies to 7-layer bars!
Melt the butter in a large pot over low heat.
And when I say melt butter over low heat, I mean low. Melting the butter slow and low is the key to keeping the butter from browning – if the butter browns or heats too fast, you’ll often end up with hard, not chewy, rice krispie treats.
Once the butter has melted, add in 2 1/2 cups of the marshmallows to the butter mixture and stir continuously until completely melted.
Take the melted marshmallow mixture off the heat and stir in the vanilla first. Then add in half of the rice krispy cereal and stir until everything is combined well.
Once that’s all mixed in, you’re going to gently stir in the rest of the cereal and the other mini marshmallows! Adding them in here makes these so much gooier and delicious than your typical rice krispy treats!
Spread the cereal mixture out evenly in the prepared baking dish, gently pressing down with a silicone spatula or a piece of parchment paper to create an even layer (but don’t press too hard).
Top the rice krispie mixture with candy corn and colorful sprinkles, again trying to evenly distribute across the top so that each treat has some of the candy and sprinkles.
Next, take a second piece of parchment paper and place it over the the top of the rice krispie treats and press down firmly all over.
The mixture may be hot so be careful to press gently!
Remove top layer of parchment paper and let cool at room temperature for about an hour (if you can wait). Then pull the entire parchment paper out of the baking dish and cut your candy corn rice krispie treats into squares to serve!
Extra Tips and Storage Info
Store leftover rice krispie treats in an airtight container for up to five days before throwing away.
Double the recipe for these holiday treats and use a 9×13 pan to make a larger batch. The treats may be a little thicker but they’ll still be yummy!
Change things up and add your favorite Halloween treats like candy eyes, colored M&Ms, or really anything else! It’s a fun way to change up the recipe but still get a sweet treat out of it!
Recipe FAQs
Can you freeze rice krispie treats?
These rice krispie treats do not freeze well. Just make a new batch rather than trying to freeze and thaw later. The great thing about rice krispie treats is that they’re fast and easy to make! So just whip up a new batch for your Halloween parties!
