Method
Chocolate Base
Prepare chocolate ice cream base
Place the slightly softened vanilla ice cream in a mixing bowl. Add the chocolate syrup and unsweetened cocoa powder. Fold gently with a rubber spatula or briefly pulse (1–2 quick bursts) in a food processor or blender until streaks of chocolate are evenly distributed but the mixture remains slightly marbled for a black-&-white effect. Do not overmix; you want visible contrast. Keep chilled while preparing toppings.
Marshmallow Topping
Warm marshmallows
Combine the mini marshmallows, marshmallow fluff, and whole milk in a small saucepan over low heat. Stir constantly until the mini marshmallows melt and the mixture is smooth and slightly glossy, about 2–3 minutes. Do not boil. Alternatively, microwave in 20-second intervals, stirring between intervals, until smooth. Remove from heat and let cool for 1–2 minutes; it should be pourable but not piping hot.
Assembly & Garnish
Top each sundae with about 1/2 cup whipped cream, sprinkle chocolate shavings or chips and crushed chocolate cookie if using. Place a maraschino cherry on top.
Serve immediately so the contrast between cold ice cream and warm marshmallow topping remains. Provide spoons and enjoy.
