Prepare the Bain-Marie by filling a small pot with ½ cup of water and bringing it to a gentle boil over medium heat. Place a heatproof bowl over the pot without touching the water to melt the marshmallows and butter.

Add 85 grams of unsalted butter and 6 cups of regular marshmallows into the bowl. Whisk continuously for 2-4 minutes until velvety smooth.

Remove the bowl from heat. Stir in ½ teaspoon of salt and a drop of red food coloring until evenly mixed.

In a separate bowl, pour 4 cups of Rice Bubbles. Pour the marshmallow mixture over the Rice Bubbles, ensuring thorough coating.

Shape the mixture into oval brains, using a butter knife to create crevices as you sculpt.

Use a toothpick dipped in red food coloring to draw veins on the brains, enhancing the spooky appearance.

Store completed treats in an airtight container. They remain fresh for up to a week.
