Prepare the Bain-Marie by filling a small pot with ½ cup of water and bringing it to a gentle boil. Place a large heatproof bowl over the pot.

Melt the butter and marshmallows in the heatproof bowl, whisking continuously for 2 to 4 minutes until smooth and glossy.

Add salt and red food coloring to the melted mixture, whisking until well incorporated.

Combine the Rice Bubbles with the marshmallow mixture, mixing gently until every bubble is coated.

Shape the mixture into oval forms to create the brains, pressing gently for definition.

Use a butter knife to draw a dent down the middle of each brain for a realistic look.

Dip a toothpick in red food coloring and draw veins on each brain treat for added spookiness.

Store the finished treats in an airtight container for up to a week.
