Ingredients for Marshmallow Rice Bubbles Halloween Brains

Gather these simple ingredients to create your own wonderfully spooky Halloween Rice Krispie treats:

85 g unsalted butter – This adds richness and helps bind everything together. If you only have salted butter, you can omit the extra salt.
6 cups regular marshmallows – These are the key to that classic gooey, chewy texture that makes these treats so beloved. Mini marshmallows work too, just measure them by volume!
4 cups Rice Bubbles (Rice Krispies) – The crispy base that gives these treats their delightful crunch.
½ teaspoon salt – A little salt balances the sweetness and enhances the marshmallow flavor.
Red food coloring – For that perfectly gruesome, brain-like appearance. A few drops are all you need to achieve a frightfully realistic look.

How to Make Marshmallow Rice Bubbles Halloween Brains

These spooky desserts are surprisingly simple, and I’ll walk you through every step to create these gruesome, delicious treats. You won’t even need to turn on the oven for these Halloween Rice Krispie treats!

Step 1: Melt MarshmallowsFirst, bring ½ cup of water to a boil in a small pot. Place a large heatproof bowl over the pot, creating a makeshift double boiler. Add the 85 g unsalted butter and 6 cups regular marshmallows to the bowl. Whisk them continuously until the marshmallows are completely melted and form a smooth, glossy paste. This usually takes about 2 to 4 minutes, and the aroma is wonderfully sweet!
Step 2: Mix with Rice BubblesRemove the bowl from the heat. Stir in the ½ teaspoon salt and a few drops of red food coloring. Whisk it all together until the color is evenly distributed, giving you that perfect gruesome hue. Pour the 4 cups Rice Bubbles into a separate large bowl. Immediately pour the warm marshmallow mixture over the Rice Bubbles. Work quickly to coat every single bubble before the marshmallow starts to set.

Step 3: Shape the BrainsLightly oil your hands or wear gloves to prevent sticking. Scoop out portions of the mixture and shape them into oval, brain-like forms. Use a butter knife to gently press a line down the middle of each ‘brain’ to mimic the sulcus, or brain fold. For an extra touch of horror in these spooky desserts, dip a toothpick into a bit more red food coloring and draw thin veins for a truly gruesome effect.

How to Store and Reheat Marshmallow Rice Bubbles Halloween Brains

Proper storage is key to keeping these easy Halloween treats fresh and spooky! Once your gruesome Marshmallow Rice Bubbles Halloween brains have cooled completely, you’ll want to store them in an airtight container. I like to layer them with parchment paper or wax paper between each layer to prevent them from sticking together. They’ll stay perfectly delicious at room temperature for about 3 to 4 days, making them great for prepping ahead of your Halloween party. If you need to store them for longer, you can freeze them for up to 3 months! Just wrap them well in plastic wrap and then foil. To reheat, simply let them thaw at room temperature for an hour or two. They’ll be just as delightfully chewy and spooky! For any questions about our storage practices, please see our terms of use.

Frequently Asked Questions About Marshmallow Rice Bubbles Halloween Brains

Can I make Marshmallow Rice Bubbles Halloween Brains with gluten-free cereal?

Yes, absolutely! You can easily substitute regular Rice Bubbles with a gluten-free puffed rice cereal. This makes them a fantastic option for guests with gluten sensitivities, ensuring everyone can enjoy these fun Halloween Rice Krispie treats.

What’s the best way to get a really vibrant red for the brain effect?

For a more intense and gruesome red color, I recommend using a gel food coloring instead of liquid. Gel colors are more concentrated, so you’ll need fewer drops to achieve a deep, alarming hue for your Marshmallow Rice Bubbles Halloween creations. Start with a small amount and add more until you get the desired spooky shade. You can learn more about food coloring from our contact page.

Can I make these Marshmallow Rice Bubbles Halloween treats dairy-free?

You sure can! To make these dairy-free, simply swap the unsalted butter for a dairy-free butter substitute or coconut oil. Ensure your marshmallows are also dairy-free, as some varieties contain gelatin or other non-vegan ingredients. This adaptation still results in wonderfully gooey and spooky Halloween Rice Krispie treats.

My brains are falling apart, what am I doing wrong?

If your brains are falling apart, it’s likely because the marshmallow mixture wasn’t quite sticky enough or you didn’t use enough of it to bind the cereal. Ensure your marshmallows are fully melted and smooth. Also, try using slightly more marshmallow mixture per treat, and don’t be afraid to press them together firmly when shaping to create a more cohesive Marshmallow Rice Bubbles Halloween treat.

Variations of Marshmallow Rice Bubbles Halloween Brains You Can Try

Feeling creative? You can easily adapt this basic recipe to make even more unique and spooky desserts for your Halloween party! Here are a few ideas to get your imagination flowing:

White Chocolate Drizzle: Melt some white chocolate or candy melts and drizzle them over the finished brains. You can even add a touch of black food coloring to the white chocolate for a contrasting vein effect on your spooky desserts.
Pumpkin Spice Twist: For a fall-inspired flavor, add a teaspoon of pumpkin pie spice to the melted marshmallow mixture. This gives a warm, cozy flavor to these creepy treats.
Dark Chocolate Coating: Dip the entire shaped brain into melted dark chocolate for a richer flavor and a different look. You can still draw red veins on top of the chocolate once it sets.
Mini Brain Bites: Instead of making larger brains, shape smaller, bite-sized versions. These are perfect for little hands or for offering a variety of treats on a dessert platter.
