A rice krispie ice cream sandwich is my weakness. Ever been stuck craving ice cream and something crunchy at the same exact second? I mean, sugary cereal bars and cold creamy scoops combined is just genius. My freezer was supposed to make me feel like an adult, but lately it’s packed with these messy, sweet inventions. Even picky eaters stop grumbling for a second when these show up after dinner. Hands down, it’s the treat I make when just regular old ice cream seems, I dunno, too ordinary. 
What You’ll Need for Rice Krispie Ice Cream Sandwiches
Seriously, don’t overthink the ingredients list. The beauty here is in the simplicity. You need:
Marshmallows. Any kind, just not stale ones from the back of your pantry.
Rice Krispies cereal. Honestly, the store brand works fine, so don’t sweat it.
Butter (I use salted, but do what makes you happy).
Ice cream (pick your favorite, or go wild and mix flavors).
That’s it! Oh, and parchment paper will save you a world of grief later. I don’t care what anyone says—parchment is a hero. Melt your butter, dump in the marshmallows, and keep your patience while they turn into goo. Then stir in your cereal, and boom. Now the real fun starts with squishing everything into place. Trust me, sticky hands just mean you’re making memories… or at least a mess. 
How to Make Rice Krispie Ice Cream Sandwiches
Alright, let’s keep it real: there’s a messy part, but it’s so worth it. First, spread half your melty rice krispie mixture in a pan lined with parchment. Don’t press it down super hard or it’ll turn into a brick—I learned that the hard way. Now, freeze that layer for 15 minutes. While you wait, let your ice cream soften a little on the counter.
Pull your pan out, scoop ice cream on top, and quickly spread it before it gets melty. Add the rest of the cereal mixture on top, then pop it all back in the freezer. Wait at least two hours (I know, torture). Chop into squares or whatever shapes your wild brain wants. They’ll probably look a bit wonky—not Instagram perfect, but honestly, who cares? That’s real life. 
Variations Worth Trying
The universe of rice krispie ice cream sandwiches? Much bigger than you think. I’ve tried swapping in chocolate cereal (don’t let the purists tell you not to). You can also dunk the finished sandwiches in melted chocolate or sprinkle on rainbow sprinkles for serious party vibes.
Try nut butter mixed into the marshmallow goo for a salty-sweet effect. I once crumbled some peanut butter cups in—probably illegal, it was so good. Or take the “fancy pants” route and add sea salt flakes on top. Didn’t think cereal could feel five-star, did you?
Storing Your Sandwiches
These dudes keep best if you wrap each one in plastic wrap (yes, all that effort is worth it later). I stack them in a big container with parchment between layers because otherwise they glue themselves into one giant block. They should last a week, maybe more, if your family doesn’t mysteriously make them disappear at midnight.
If you’re prepping for a party, make ’em a day ahead—saves last-second panic.
“Made these for my kid’s birthday and they vanished before I even sat down. Melted a little quick on the porch, but honestly, that’s just extra finger-licking fun.” – Jean from Boston
Serving Suggestions
- Slice ‘em into mini squares for snack time, or go big for a showoff dessert.
- Roll the edges in mini chocolate chips for bonus crunch.
- Drizzle caramel or chocolate sauce all over (messy but hey, YOLO).
- Serve with fresh berries on the side for a fake-out healthy twist.
Common Questions
Q: Can I use store-bought marshmallow fluff instead of melting marshmallows?
A: Yeah, it works in a pinch, but the classic marshmallows give a better texture.
Q: My cereal bars came out rock hard! What went wrong?
A: Probably pressed them down too much or cooked the marshmallows a bit too long. Be gentle and don’t stress.
Q: Do these need to be stored in the freezer, or will the fridge do?
A: Freezer is your best bet—otherwise, they’ll get way too sticky and sad.
Q: Are they gluten-free?
A: The original cereal usually isn’t, but there are gluten-free versions. Just double-check your labels.
Q: What’s the best ice cream flavor for these?
A: Vanilla is classic but honestly, go wild. Anything from strawberry to pistachio is delicious if you’re brave.
