How to Make Marshmallow Rice Bubbles Halloween Brains
1. Melt the Marshmallows
In a large pot over low heat, melt the butter. Once melted, add the mini marshmallows and stir until completely gooey and smooth. Add in the food coloring and vanilla extract. Stir well until you get a fleshy pink color.
2. Stir in the Rice Bubbles
Remove the pot from the heat and quickly fold in the Rice Bubbles. Stir until they’re all coated in that sticky pink marshmallow mix.
3. Shape the Brains
Grease your hands well with cooking spray. While the mixture is still warm but cool enough to handle, scoop a handful and shape into ovals. Use a butter knife or skewer to gently create the classic brain-like grooves down the center and sides. Perfect Spooky Night Snacks fun!
4. Let Them Set
Place your brains on a lined tray and pop them in the fridge for about 30 minutes to firm up.
Pro Tips for Perfect Brains
- Don’t skimp on greasing your hands—it makes shaping so much easier.
- Work quickly; the mixture sets fast!
- Want even more creepy flair? Drizzle with red icing “blood” or use candy eyeballs.
Flavor Variations
- Swap vanilla for almond or strawberry extract.
- Add a handful of mini chocolate chips for “brain matter.”
- Use colored candy melts instead of food dye for a richer tint.
Serving Suggestions
- Serve on a Halloween-themed platter with spooky decorations.
- Pair with a witchy punch or monster milkshake from your Halloween Party Food And Drinks menu.
- Wrap individually for Halloween Party Foods For Kids or trick-or-treaters.
Make-Ahead and Storage
You can shape the brains a day ahead and store them in an airtight container at room temp. Just don’t refrigerate too long—they can get a bit hard.
Leftovers?
Store leftovers in a sealed container for up to 3 days. Refresh with a quick zap in the microwave if they firm up too much.
Freezing
Not recommended—these treats are best enjoyed fresh. Freezing alters the texture.
Reheating
If needed, microwave one brain for 5–8 seconds to soften slightly before eating.
FAQs
Can I use regular marshmallows instead of mini?
Yes! Just chop them up a bit first so they melt faster.
What if I don’t have food coloring?
No worries—they’ll still taste great, just won’t look as spooky.
Can I make these dairy-free?
Absolutely! Use a plant-based butter and check your marshmallows for gelatin-free versions.
How do I transport them to a party?
Lay them in a single layer in a lidded container or use cupcake liners to separate them. Great for Spooky Snacks For Kids!
