Funfetti Marshmallow Cereal Bars for a Sweet Snack

How to Make Funfetti Marshmallow Cereal Bars

Step 1: Prepare Your Pan

Line an 8×8-inch square pan with parchment paper or lightly grease it to prevent the bars from sticking when they set.

Step 2: Melt Butter and Marshmallows

In a large saucepan over low heat, melt the butter completely. Add the mini marshmallows and stir continuously until fully melted and smooth, creating a creamy mixture perfect for binding the cereal together.

Step 3: Add Vanilla and Sprinkles

Remove the marshmallow mixture from heat and stir in the vanilla extract along with half of the rainbow sprinkles. This ensures the sprinkles stay colorful and don’t melt into the marshmallow.

Step 4: Mix in Cereal

Gently fold the crispy rice cereal into the marshmallow mixture until all pieces are evenly coated and the cereal is thoroughly combined.

Step 5: Press into Pan and Add Remaining Sprinkles

Transfer the mixture to your prepared pan and press down firmly and evenly using a spatula or your hands to compact the bars. Sprinkle the remaining rainbow sprinkles on top for an extra pop of color and gently press them in.

Step 6: Let Set and Slice

Allow the bars to cool and firm up at room temperature for about 30-45 minutes. Once set, lift the bars from the pan using the parchment paper edges and cut into squares or rectangles to serve.

Pro Tips for Making Funfetti Marshmallow Cereal Bars

Don’t Overheat Marshmallows: Melt gently on low heat to avoid burning and keep the mixture smooth.
Use Fresh Sprinkles: Old sprinkles may dull in color, so use bright, fresh ones for maximum visual impact.
Pack the Bars Firmly: Pressing the mixture well into the pan helps bars hold their shape and prevents crumbling.
Cut with a Warm Knife: Dip the knife in hot water and wipe dry before slicing for clean cuts without tearing the bars.
Store Properly: Keep bars in an airtight container to maintain freshness and chewiness.

How to Serve Funfetti Marshmallow Cereal Bars

Garnishes

Try topping each bar with a small dollop of whipped cream or a drizzle of white or colored chocolate to make them extra special. Fresh fruit like sliced strawberries or a sprinkle of edible glitter can add a festive look for celebrations.

Side Dishes

Pair Funfetti Marshmallow Cereal Bars with a cold glass of milk, hot chocolate, or your favorite fruit smoothie for a balanced snack that complements the sweetness and texture perfectly.

Creative Ways to Present

Serve these bars on colorful plates or wrap them individually in clear cellophane tied with ribbons for parties, gift bags, or lunchbox treats. They also work great as interactive snacks where kids can add their own sprinkles or toppings.

Make Ahead and Storage

Storing Leftovers

Store leftover Funfetti Marshmallow Cereal Bars in an airtight container at room temperature for up to 3 days to keep them chewy and fresh.

Freezing

Wrap bars individually in plastic wrap and place in a freezer-safe bag or container. They freeze well for up to 1 month, making this recipe convenient for meal prep or unexpected guests.

Reheating

Thaw frozen bars at room temperature for about 30 minutes. For a warm treat, microwave them for 10-15 seconds, but be careful not to overheat or they may become too soft.

FAQs

Can I use a different type of cereal?

Yes! While crispy rice cereal works best for that classic chewy crunch, you can substitute with other cereals like cornflakes or Cheerios depending on your taste preference.

Are Funfetti Marshmallow Cereal Bars suitable for vegan diets?

The traditional recipe uses butter and marshmallows containing gelatin, so it’s not vegan, but you can swap in vegan butter and vegan marshmallows to make a plant-based version.

How do I prevent sprinkles from fading color?

Add sprinkles after removing the marshmallow mixture from heat and fold in gently to preserve their vibrant colors without melting.

Can I store these bars in the refrigerator?

It’s best to store them at room temperature because refrigeration can make them hard and less chewy, but if your kitchen is warm, the fridge can help preserve them without melting.

What’s the best way to cut the bars neatly?

Use a sharp knife dipped in hot water and wiped dry before each cut to prevent sticking and achieve clean, neat slices.
