Ingredients You’ll Need
Here’s what you need to whip up these Halloween brain treats:
- 85 g unsalted butter
- 6 cups regular marshmallows
- 4 cups Rice Bubbles (or Rice Krispies)
- ½ teaspoon salt
- Red food colouring
Step-by-Step Instructions
Follow these steps carefully to get the best results for your Halloween brains:
- Prepare a Bain-Marie: Add ½ cup of water to a small pot and bring it to a boil. Place a large heatproof bowl over the pot of boiling water.
- Melt the Base: Place the butter and marshmallows into the heatproof bowl. Whisk continually until a smooth paste forms (about 2–4 minutes).
- Add Salt & Colour: Carefully remove the bowl from the heat. Stir in the salt and a drop (or more) of red food colouring, whisking until combined.
- Mix with Rice Bubbles: In a large mixing bowl, add the Rice Bubbles. Pour the marshmallow mixture over them and stir until fully coated.
- Shape the Brains: Oil your hands to prevent sticking. Shape the mixture into oval “brain” shapes. Use a butter knife to create a dent in the middle for brain texture.
- Draw the Veins: Dip a toothpick into red food colouring and draw vein-like lines across the brains to enhance the spooky effect.
- Store & Serve: Keep the brains in an airtight container for up to one week. Serve at parties or package individually for trick-or-treating.

Storage & Make-Ahead Tips
To keep your Halloween brains fresh:

- Make them a day or two before the party to save time – they’ll stay perfectly fresh.

Yes, but reduce or omit the added salt to balance the flavor.
How can I make these gluten-free?
Use a certified gluten-free puffed rice cereal to make this recipe gluten-friendly.
Can I freeze these Halloween brains?
