How to Make Marshmallow Rice Bubbles Halloween Brains
Step 1: Prepare the Bain-Marie
Start by putting 1/2 cup of water into a small pot and let it come to a boil. Place a large heatproof bowl over the pot of boiling water.
Step 2: Melt Butter and Marshmallows
In the large heatproof bowl, combine the unsalted butter and regular marshmallows. Continually whisk until you form a smooth paste; this should take about 2-4 minutes.
Step 3: Add Salt and Color
Carefully remove the heatproof bowl from the pot using oven mitts or a tea towel. Stir in the salt, along with a drop or more of red food colouring, whisking until evenly mixed.

Oil your hands lightly and shape the coated mixture into ovals. Using a butter knife, create a dent in each oval to resemble brain halves. Dip a toothpick into red food coloring and draw veins on each brain shape.

Common Mistakes to Avoid
It’s easy to make mistakes while creating Marshmallow Rice Bubbles Halloween Brains. Here are some common pitfalls and how to steer clear of them.
- Ignoring the Bain-Marie Technique: Many skip this step, which helps melt butter and marshmallows evenly. Always use a heatproof bowl over simmering water for smooth results.
- Overmixing the Rice Bubbles: Mixing too aggressively can break the Rice Bubbles apart, resulting in a less appealing texture. Gently fold the marshmallow mixture in until all pieces are coated.
- Using Too Much Food Coloring: Overdoing it can lead to an unnatural color. Add food coloring gradually and mix until you reach your desired hue for a more realistic effect.
- Not Oiling Your Hands: Failing to oil your hands makes shaping the brains messy and sticky. Always oil them before handling the mixture to keep it manageable.
- Skipping Airtight Storage: Leaving your treats exposed can make them stale quickly. Store them in an airtight container to maintain their freshness for up to a week.
