Easy Halloween Rice Krispie Treats

Okay, so Halloween, right? It’s basically an excuse to eat candy for dinner, and I am HERE for it. But sometimes, you need something a little… less cavity-inducing. Enter: Easy Halloween Rice Krispie Treats — the perfect way to get your spooky sweet fix without the sugar crash of doom. Plus, they are SO. FREAKING. EASY. Seriously, if you can melt butter, you can nail this.
My husband, bless his heart, is a total sucker for these. Last year, I made a batch for a Halloween party, and he snuck, like, half of them before anyone else even arrived. I caught him red-handed (or, marshmallow-handed?), and he just gave me this sheepish grin. Now, I swear, the second I even LOOK at a bag of marshmallows, he starts chanting, “Rice Krispie Treats! Rice Krispie Treats!” It’s adorable… and slightly terrifying. The kids love helping too, even if more sprinkles end up on the floor than on the treats.
Why You’ll Love This Easy Halloween Rice Krispie Treats
- It’s basically foolproof. I mean, I’ve messed up toast before, but never Rice Krispie Treats.
- Spooky, cute, and Instagrammable… if you’re into that. I just like eating them.
- Kids love ’em. Adults love ’em. Even your grumpy Uncle Gary will probably sneak one.
- You can throw in all sorts of weird Halloween candy bits to jazz them up. Seriously, get creative!
- Requires, like, zero baking skill. Total win in my book.
How to Make It
Okay, so first things first, grab a big ol’ pot and melt your butter. Don’t burn it! Unless you like the taste of burnt butter… which, hey, no judgment here. Once that’s all melty and delicious, dump in your marshmallows. Now, stir, stir, stir! Keep stirring until they’re all smooth and gooey. This is where you get your arm workout in for the day.
Next, take the pot off the heat! VERY IMPORTANT STEP or you’ll end up with cement squares. Pour in your Rice Krispies and stir like crazy again until everything is coated. This part can get a little sticky, so maybe grease your spatula or something. I usually just lick my fingers (don’t tell anyone).
Now, grab a baking pan (9×13 is my go-to) and grease it up. Seriously, grease it well, or you’ll be scraping Rice Krispie Treat shards for days. Pour the mixture into the pan and press it down. I use a spatula or sometimes just my hands (again, greased!).

Finally, the best part: SPRINKLES! Go wild. I mean, it’s Halloween. You can’t have too many sprinkles. Let them cool for a bit before cutting into squares. Or, you know, just dig in warm. No one’s judging. Seriously, Easy Halloween Rice Krispie Treats is the best!
Ingredient Notes
- Butter: Don’t skimp on the butter, people! It’s what makes these so rich and delicious. Salted or unsalted works, but I usually use salted because I’m a rebel.
- Marshmallows: Okay, so I usually go for the big, classic ones, but the mini ones melt faster. Just saying. And don’t even THINK about using stale marshmallows. Just…don’t.
- Rice Krispies Cereal: Obviously. But sometimes I throw in other cereals too! Cocoa Krispies for extra chocolatey goodness? Don’t mind if I do.
- Halloween Sprinkles: The more, the merrier! I usually grab a mix of shapes and colors. The ones with the little ghosts are my fave.
- Vanilla Extract: Okay, I usually forget this, but if you remember, it adds a nice little something-something. Like, makes it taste fancy.
Recipe Steps:
- Melt: Melt butter in a large pot over low heat.
- Incorporate: Add marshmallows and stir until completely melted and smooth.
- Remove: Take the pot off the heat.
- Combine: Stir in Rice Krispies until evenly coated.
- Press: Press the mixture into a greased 9×13 inch baking pan.
- Decorate: Sprinkle with Halloween sprinkles.
- Cool: Let cool completely before cutting into squares.
- Serve: Enjoy!
What to Serve It With
Honestly? These are great on their own. But if you’re feeling fancy, you could serve them with a glass of milk (chocolate milk, duh!). Or a scoop of ice cream. Or just another Rice Krispie Treat.
Tips & Mistakes
- Don’t overcook the marshmallows! They’ll get hard and your treats will be tough.
- Grease your pan! I cannot stress this enough. Unless you want to spend an hour scraping.
- Don’t pack the mixture too tightly! You want them to be soft and chewy, not dense and brick-like.
- Sprinkles are your friend! Don’t be shy. Go wild!
- Sometimes I microwave the butter and marshmallows. Don’t tell anyone, but it works in a pinch. Just keep an eye on it so it doesn’t explode.
Storage Tips
Store these bad boys in an airtight container at room temperature. They’ll stay good for a few days… if they last that long. Honestly, I’ve eaten them cold straight from the fridge for breakfast. Don’t judge me. They’re basically cereal, right?
Variations and Substitutions
- Different Cereals: Cocoa Krispies, Fruity Pebbles, even Corn Flakes (if you’re feeling…adventurous?).
- Nut Butter: Swirl in some peanut butter or almond butter with the marshmallows for extra flavor.
- Chocolate: Melt some chocolate chips and drizzle them over the top. Dark chocolate is my personal fave.
- Halloween Candy: Throw in some chopped-up candy bars, gummy worms, or candy corn. It’s Halloween, after all!
- Marshmallow Fluff: I tried to make this once and it didn’t go well. I think it’s a no from me, dawg.
