Spooky Sweet Treat That’s Fun & Easy
Get ready to spook your tastebuds this Halloween with Marshmallow Rice Bubbles Halloween Brains! These creepy, chewy, crispy little brain-shaped treats are perfect for parties, kids, or anyone who loves fun seasonal desserts. With just 5 ingredients and under 20 minutes from start to finish, they’re one of the easiest Halloween no-bake recipes you’ll make. The marshmallow gives sweetness and chew, Rice Bubbles (or Rice Krispies) add crisp texture, and with a little red food coloring, they look eerily like little brains. Creepy, cute, and totally delicious.
Ingredients
- 85 g unsalted butter
- 6 cups regular marshmallows
- 4 cups Rice Bubbles (Rice Krispies)
- ½ teaspoon salt
- red food coloring
Equipment Needed
- Small pot plus a heat‑proof bowl (for a bain‑marie / double‑boiler)
- Whisk
- Butter knife
- Toothpick
- Oil for hands
Instructions
- Bring ½ cup water to a boil in a small pot. Place a large heatproof bowl over the pot (bain‑marie).
- Add the butter and marshmallows to the bowl. Whisk continuously until the marshmallows melt and the mixture becomes a smooth paste (about 2–4 minutes).
- Remove the bowl from the heat (use oven mitts or a cloth). Stir in the salt and one (or more) drops of red food coloring, whisking well so the color distributes evenly.
- In a separate large bowl, pour in the Rice Bubbles. Pour the marshmallow mixture over them. Mix quickly but thoroughly so that each Rice Bubble is coated before the marshmallow firms up.
- Once mixed, lightly oil your hands. Scoop portions of the mixture and shape into oval brain‑like forms. Use a butter knife to make a dent in the middle of each to mimic the sulcus (brain fold). Dip a toothpick into red food coloring to draw veins for extra gruesome effect.
- Store in an airtight container. They stay good for up to a week.
