Marshmallow Rice Krispies Halloween Brains Recipe
Introduction
This Marshmallow Rice Krispies Halloween Brains recipe transforms a classic treat into a spooky delight perfect for Halloween parties. With a glossy marshmallow coating tinted red, these brain-shaped snacks are both fun to make and delicious to eat.

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.
- Step 2: Add the butter and marshmallows to the bowl and melt them slowly, whisking continuously until the mixture is smooth and glossy.
- Step 3: Remove the bowl from the heat. Whisk in the salt and 2–3 drops of red food coloring to create a brain-like color.
- Step 4: Pour the marshmallow mixture over the Rice Krispies cereal. Stir quickly and thoroughly to coat the cereal evenly.
- Step 5: Oil your hands lightly to prevent sticking. Shape portions of the mixture into oval brain forms.
- Step 6: Using a butter knife, carve a groove down the center of each shape to mimic the brain’s folds.
- Step 7: Dip a toothpick in red food coloring and draw vein patterns on the brains to add a spooky, realistic effect.
Tips & Variations
- For extra realism, add a small amount of blue or purple food coloring along with red to create more vein color variation.
- If you prefer a less sweet treat, reduce the amount of marshmallows slightly and add mini pretzel sticks for a salty crunch.
- You can also shape these treats using silicone brain molds for a more uniform appearance.
Storage
Store the brain-shaped Rice Krispies treats in an airtight container at room temperature for up to 3 days. Avoid refrigeration, as it can make them hard and less enjoyable. If needed, warm them slightly in the microwave for a few seconds to soften before serving.

FAQs
Can I use a microwave instead of a bain-marie for melting the marshmallows?
Yes, you can melt the butter and marshmallows in a microwave-safe bowl in 30-second increments, stirring in between, until smooth. However, melting over a bain-marie allows for gentler heating and reduces the risk of burning.
How do I prevent the marshmallow mixture from sticking to my hands?
Oiling your hands lightly with butter or cooking spray before shaping the treats will help prevent sticking and make shaping much easier.

Ingredients
Main Ingredients
- 6 tbsp Unsalted butter – creates a smooth base
- 6 cups Regular marshmallows – primary binding agent
- 4 cups Rice Krispies cereal – texture foundation
- ½ tsp Salt – enhances sweetness
- As needed Red food coloring – creates brain effect
Instructions
- Prepare bain-marie: Fill a medium saucepan with ½ cup of water and bring it to a gentle boil. Place a heatproof bowl over the saucepan to create a bain-marie setup, ensuring the bowl does not touch the water.
- Melt butter and marshmallows: Add butter and marshmallows to the heatproof bowl. Slowly melt while whisking continuously until the mixture becomes smooth and glossy, ensuring even melting without scorching.
- Add salt and coloring: Remove the bowl from heat and whisk in ½ teaspoon of salt along with 2-3 drops of red food coloring to give the mixture a subtle pinkish hue resembling brain tissue.
- Combine with cereal: Pour the marshmallow mixture over the Rice Krispies cereal in a large bowl. Stir quickly and thoroughly to coat all the cereal evenly before the mixture sets.
- Shape the brains: Lightly oil your hands to prevent sticking, then take portions of the coated cereal and shape them into oval, brain-like forms. Using a butter knife, carve a groove down the center to mimic the brain’s hemispheres.
- Add vein details: Dip a toothpick into red food coloring and draw vein-like patterns across the surface of the shaped brains to create a spooky, realistic effect perfect for Halloween treats.
Notes
- Use oil on your hands generously to prevent sticking when shaping the brains.
- Adjust the amount of red food coloring to get the desired intensity of the brain color.
- Work quickly when mixing marshmallow and cereal as the mixture sets fast.
- Store finished brains in an airtight container to keep them fresh and chewy.
- For extra flavor, you can add a teaspoon of vanilla extract to the melted marshmallow mixture before combining with the cereal.
