Begin by filling a small pot with about 1/2 cup of water and bring it to a gentle boil over medium heat. Place a large heatproof bowl over the pot, ensuring it doesn’t touch the water.

Add the unsalted butter and regular marshmallows to the bowl above the simmering water. Stir constantly with a whisk for about 2–4 minutes, until the mixture is completely smooth and glossy.

Remove the bowl from the heat. Mix in the salt and red food coloring, stirring until evenly distributed.

In a separate large bowl, pour in your Rice Bubbles. While the marshmallow mixture is still hot, pour it over the Rice Bubbles and quickly mix.

Lightly oil your hands to prevent sticking and shape the mixture into an oval resembling a brain. Use a butter knife to create a dent in the center.

Once cooled and set, place the treats in an airtight container to keep fresh for up to a week.
