Step‑by‑Step Instructions for Marshmallow Rice Bubbles Halloween Brains
Step 1: Prepare a Bain-Marie
Begin by filling a small pot with 1/2 cup of water and bringing it to a boil over medium heat. Place a large heatproof bowl on top of the pot to create a Bain-Marie. This gentle heating method prevents your ingredients from burning while melting the butter and marshmallows for your Marshmallow Rice Bubbles Halloween Brains.
Step 2: Melt Butter and Marshmallows
Add the unsalted butter and regular marshmallows to the bowl above the boiling water. Whisk the mixture continuously for about 2-4 minutes until it transforms into a smooth, gooey paste with no lumps visible. The mixture will become sticky and glossy, indicating it’s perfectly melted and ready for the next step.
Step 3: Mix in Salt and Color
Carefully remove the bowl from the heat and stir in the salt, followed by a few drops of red food coloring. Mix thoroughly until the color is evenly distributed, turning your marshmallow mixture a spooky shade of red. This vibrant hue will enhance the eerie appearance of your Marshmallow Rice Bubbles Halloween Brains.
Step 4: Combine with Rice Bubbles
In a separate large mixing bowl, add the Rice Bubbles. Pour the warm marshmallow mixture directly over the cereal. Quickly and thoroughly stir the two together while the mixture is still hot, ensuring each Rice Bubble is completely coated in the sticky goodness. This step is crucial for achieving the right consistency in your treats.
Step 5: Shape into Brains
Lightly oil your hands to prevent sticking, then scoop portions of the mixture and shape them into oval forms resembling brains. Focus on creating a bumpy texture and use your thumb to press in a dent on one side to mimic brain folds. This step will ensure your Marshmallow Rice Bubbles Halloween Brains not only taste fantastic but also look delightfully spooky.
Step 6: Draw Veins for Detail
Once your brain shapes are formed, use a toothpick dipped in red food coloring to draw thin lines resembling veins on the surface of each treat. Be creative with the vein patterns to enhance their frightful appearance. This attention to detail will make your Halloween treats irresistible and visually striking at any festive gathering.
Step 7: Store Properly
After decorating, allow the Marshmallow Rice Bubbles Halloween Brains to cool completely on a baking sheet. Once set, store them in an airtight container for up to one week. This will keep them fresh and enjoyable, ready for any Halloween festivities or surprise treats that come your way!

Make Ahead Options
These Marshmallow Rice Bubbles Halloween Brains are perfect for meal prep and can save you time during the spooky season! You can prepare the marshmallow mixture and shape the brains up to 24 hours in advance. Simply follow steps 1-5 of the recipe, then store the shaped brains in an airtight container in the refrigerator. To maintain their quality, ensure they are completely cooled before sealing to prevent moisture buildup. When you’re ready to serve, simply let them sit at room temperature for a few minutes and then decorate with red food coloring in a scary vein pattern. This way, you’ll have delightful Halloween treats ready to impress with minimal last-minute effort!
