Marshmallow Rice Krispies Halloween Brains Recipe
Introduction
These Marshmallow Rice Krispies Halloween Brains are a fun and spooky treat perfect for the spooky season. Soft, chewy, and delightfully creepy, they’re sure to impress at any Halloween party.

Ingredients
- 6 tbsp Unsalted butter
- 6 cups Regular marshmallows
- 4 cups Rice Krispies cereal
- ½ tsp Salt
- Red food coloring (as needed)
Instructions
- Step 1: Fill a medium saucepan with ½ cup water and bring it to a gentle boil. Place a heatproof bowl over the saucepan to create a bain-marie (double boiler).
- Step 2: Add the butter and marshmallows to the bowl. Melt them slowly while whisking continuously until the mixture is smooth and glossy.
- Step 3: Remove the bowl from heat, then whisk in the salt and 2–3 drops of red food coloring until evenly combined.
- Step 4: Pour the marshmallow mixture over the Rice Krispies cereal. Stir quickly to coat the cereal evenly before it sets.
- Step 5: Lightly oil your hands to prevent sticking. Shape portions of the mixture into oval forms resembling brains. Use a butter knife to carve a groove down the center of each shape.
- Step 6: Dip a toothpick in red food coloring and draw vein-like patterns on the shaped brains for a realistic, spooky effect.
Tips & Variations
- Use gel food coloring for a more vibrant red without adding extra liquid to the mix.
- For extra flavor, add a teaspoon of vanilla extract to the melted marshmallow mixture before combining with the cereal.
- Try different cereal bases like Cocoa Krispies to create a chocolatey brain variation.
Storage
Store the shaped brains in an airtight container at room temperature for up to 3 days. Keep them dry to maintain their chewy texture. If they become slightly hard, warm briefly in the microwave to soften before serving.
