Step‑by‑Step Instructions for Marshmallow Rice Bubbles Halloween Brains
Step 1: Prepare Bain-Marie
Begin by filling a small pot with ½ cup of water and set it over medium heat to bring it to a gentle boil. Once the water is simmering, place a large heatproof bowl over the pot, ensuring the bottom of the bowl does not touch the water. This creates a double boiler effect, perfect for melting the ingredients for your Marshmallow Rice Bubbles Halloween Brains.
Step 2: Melt Ingredients
Add 4 tablespoons of unsalted butter and 16 ounces of regular marshmallows into the bowl above the simmering water. Whisk continuously for about 2-4 minutes until the mixture is completely smooth and glossy, resembling a creamy sauce. Keep a close eye on it, as you want the marshmallows to melt fully without burning.
Step 3: Add Seasoning
Carefully remove the bowl from the heat, taking care not to burn yourself. Sprinkle in ½ teaspoon of salt to enhance the flavor and mix well. Then add a few drops of red food coloring, stirring until the color is evenly distributed throughout the marshmallow mixture, giving it a brain-like appearance.
Step 4: Combine with Rice Bubbles
In a large mixing bowl, measure out 6 cups of Rice Bubbles and pour the melted marshmallow mixture over them. Use a spatula to gently fold the mixture until all the Rice Bubbles are thoroughly coated. This step is crucial for ensuring your Marshmallow Rice Bubbles Halloween Brains have the right texture and flavor.
Step 5: Shape Brains
Once fully combined, it’s time to shape your treats. Lightly oil your hands to prevent sticking, then grab handfuls of the mixture and mold them into oval shapes that resemble brains. Use the flat side of a butter knife to create a dent in the center of each brain for added detail.
Step 6: Decorate
For a truly spooky effect, take a toothpick and dip it into some more red food coloring. Use it to draw vein-like designs on the surface of each shaped brain, adding an extra touch of eeriness to your Marshmallow Rice Bubbles Halloween Brains that will impress your friends and family.
Step 7: Store
Let your treats cool completely at room temperature for about 10-15 minutes before transferring them to an airtight container. These fun snacks can be stored at room temperature for up to a week, making them a perfect Halloween treat for any occasion!

You can melt the butter and marshmallows, and mix in the salt and food coloring up to 24 hours in advance, refrigerating the mixture in an airtight container until you’re ready to combine it with the Rice Bubbles. This keeps everything fresh while saving you time on busy Halloween days. When you’re ready to prepare your spooky treats, simply reheat the mixture gently in the microwave until it becomes pourable, then mix with the Rice Bubbles as instructed.

Storage Tips for Marshmallow Rice Bubbles Halloween Brains
Room Temperature: Store the treats in an airtight container at room temperature to maintain their crispness for up to 7 days. Avoid exposure to humidity, which can make them sticky.
