Super creamy chocolate marshmallow swirl ice cream is a decadent, cooling treat. Break out the toasted marshmallows, hot fudge, and graham crackers for an over-the-top s’mores sundae bar!
Continue whisking until the dry ingredients are dissolved. Pour the mixture into an airtight container and chill in the refrigerator for at least 4 hours or overnight.
Spread half of the marshmallow cream over the ice cream and swirl through with a knife. Repeat with remaining ice cream and marshmallow topping and swirl with a knife.
