Confetti Marshmallow Chocolate Squares are the sweet fix I reach for when I want something fun, fast, and impossible to mess up. Maybe you’ve been there too: you promised a treat for a school event or a last minute get together, but you’re short on time and energy. These squares save the day. They’re colorful, chewy, and chocolatey in all the right ways. No oven required, and the cleanup is painless. Let me show you how I make them so they turn out glossy, slice clean, and disappear fast.
How To Make The Chocolate Confetti Squares
I’ve made a lot of easy desserts, and this one is still the most requested. It hits that nostalgia button hard. Think rich chocolate, creamy peanut butter, and bouncy mini marshmallows with a pop of color from sprinkles or candy chips. The secret is gentle heat and patience while it sets. That’s it. If you’ve got 15 minutes to stir, you’re basically done.
Ingredients
- 3 cups mini marshmallows, plus a handful more for topping
- 1 cup semisweet chocolate chips
- 1 cup butterscotch chips or white chocolate chips
- 1/2 cup creamy peanut butter
- 3 tablespoons unsalted butter
- 1 teaspoon vanilla extract
- 1/4 teaspoon fine salt
- 1/3 cup rainbow sprinkles or colored candy chips
- Optional: 1/2 cup crushed graham crackers or crispy rice cereal for crunch
Step-by-step
- Line an 8 inch square pan with parchment, leaving a little overhang so you can lift the slab out later.
- Melt the chocolate chips, butterscotch chips, peanut butter, and butter in a saucepan over very low heat. Stir slowly until smooth. Take your time, don’t rush.
- Remove from heat. Stir in vanilla and salt. Let the mixture cool for 2 to 3 minutes so it is warm and pourable but not hot.
- Fold in mini marshmallows and sprinkles until coated. If you’re adding graham crumbs or crispy cereal, add them now.
- Scrape into the lined pan and smooth the top. Press on a few extra marshmallows and a pinch of sprinkles for looks.
- Chill until fully set, about 2 hours. Lift out by the parchment and slice into neat squares with a sharp knife.
Want perfect melt without scorching your chocolate? I’ve got a quick guide here: how to melt chocolate without seizing. It keeps everything silky. Two other keys: allow a short cooling pause before adding marshmallows so they don’t melt, and chill for at least 2 hours so slices are clean.
For friends who ask, yes, these are the same playful bites from my childhood church bake sale. Only difference is I measure and stir more gently now. If you’re new to easy treats, start here, then try other fun bars later.
Oh, and because SEO folks keep asking, here’s a quick structured reference for this recipe.
No-bake Chocolate and Peanut Butter Marshmallow Square
This section is for my peanut butter lovers. That creamy, salty sweetness is why these squares are so addictive. The chocolate gives depth, the butterscotch or white chocolate adds extra smoothness, and the peanut butter ties everything together. It’s a no-bake treat that still feels special.
Swaps and variations
Here’s how I tailor the batch depending on my crowd:
Peanut butter: Creamy gives the silkiest mixture. Natural peanut butter works if it’s well stirred and not too runny. If allergens are a concern, use sunflower seed butter or almond butter instead.
Chocolate: Semisweet is my default. Milk chocolate makes it sweeter and softer. Dark chocolate gives a grown up vibe. You can also split half semisweet and half milk.
Texture add-ins: Crushed pretzels are amazing for salty crunch. Toasted coconut flakes bring extra chew. Chopped peanuts or pecans taste great, just keep the total add-ins around 1 cup so the bars still hold together.
Color: If you want the rainbow effect, use colorful mini marshmallows or toss in pastel candy-coated chips. Those pops of color are what give Confetti Marshmallow Chocolate Squares their party energy.

Christmas Favorites
Holiday baking can be joyful and chaotic, which is exactly why these bars are on my December shortlist. They’re quick to make, happy to travel, and they look like little gifts all by themselves. For Christmas, I swap rainbow sprinkles for red and green jimmies, and sometimes drizzle white chocolate across the top for a snow look.
Make it festive
Try these easy tweaks for extra cheer:
Peppermint twist: Stir in crushed candy cane. The cool mint with chocolate is peak holiday flavor.
Gingerbread vibe: Add a pinch of cinnamon and ginger to the melted chocolate mixture and fold in crumbled ginger snaps instead of graham crackers.
Gift packaging: Slice into bite size squares, place in mini cupcake liners, and tuck 6 to 8 into small tins. Write a note and drop off for neighbors. The texture holds up well, and they look super cute.
These Confetti Marshmallow Chocolate Squares also stack perfectly in cookie boxes without sticking if you use parchment between layers. If you need inspiration for a bigger holiday lineup, peek at my running list of Christmas treats and edible gifts. I rotate a few every year but these squares never leave the roster.
School Lunch Ideas
I know lunchboxes can be a puzzle. On busy mornings, I slice a batch of squares, wrap each piece in parchment, and tuck one into the lunch bag as a surprise sweet. It’s a morale booster for kids and adults alike. Plus, they’re sturdy enough to survive the backpack adventure.
Pack and store
- Cut small. Think two inch squares for an easy portion.
- Wrap in parchment or wax paper, then slip into a reusable snack bag.
- Keep chilled for best texture, but they do fine at room temp for a few hours.
- For nut free schools, use seed butter and skip any nut add-ins.
I keep a stash in the freezer too. Freeze sliced pieces on a sheet pan, then transfer to a container. They thaw in about 20 minutes and taste fresh. If lunch needs more balance, pair a square with fruit and a little protein like cheese or yogurt. More ideas for easy packing are here: school lunchbox ideas. That page is where I save my favorite shortcuts and swaps.
Sharing is Caring
These bars are conversation starters. Put out a plate at book club or game night and watch people smile. They feel homemade in the best way, with soft edges and generous chocolate. If you’re bringing a dessert to a potluck, double the recipe and use a 9 by 13 inch pan. It still sets in the same amount of time if you chill it well.
“I brought a tray of these to our neighborhood cookout and they vanished before the burgers were off the grill. Three people asked for the recipe on the spot. My new potluck staple.”
When I’m sharing, I always include a little card with ingredient notes for allergy peace of mind. I also mark the batch as nut free if I used sunflower seed butter. If you want to build a whole dessert board, mix these squares with salty snacks and cut fruit so everyone gets a little sweet, a little crunch, and something fresh. And for crowd pleasing variety, I often pair with these make ahead favorites from my archives: snack tray and dessert board ideas. Confetti Marshmallow Chocolate Squares hold their own in any lineup yet play nicely with others.
Common Questions
How long do these keep?
They stay great in the fridge for up to 5 days in an airtight container. Freeze up to 2 months, well wrapped.
Can I skip peanut butter?
Yes. Use sunflower seed butter for a nut free version or increase chocolate and butter slightly to maintain texture.
Why did my marshmallows melt?
The chocolate mixture was too hot. Let it cool a couple minutes before folding in marshmallows and stir gently.
Do I have to use butterscotch chips?
No. White chocolate works, or just use all semisweet chocolate. Butterscotch adds that classic retro flavor.
How do I get clean slices?
Chill fully, use a sharp knife, and wipe the blade between cuts. Lightly spray the knife with oil for extra clean edges.
