Secret Recipe Chocolate Shakes for a Crowd
Secret Recipe Chocolate Shake for Hamburger Night
This secret recipe chocolate shake is designed for a crowd. Vanilla ice cream, milk, chocolate syrup, vanilla, and a little sugar combine into a smooth, old-fashioned shake that can be served with a ladle.
The large quantity makes this recipe useful for family gatherings, cookouts, birthday parties, or hamburger night. For a smaller group, divide every ingredient evenly to make a half or quarter batch.
Why This Chocolate Shake Works

Equipment You Will Need

Mistakenly Smart Note
How to Keep the Shake Creamy
Start with cold milk and only slightly softened ice cream. Ice cream that has fully melted will produce a thinner shake.
Stir the container occasionally while serving. The mixture may become thicker at the top and thinner near the bottom as it sits.
Serving Suggestions
Serve the chocolate shake with cheeseburgers, fries, onion rings, hot dogs, or grilled sandwiches. Whipped cream and chocolate drizzle can be added to individual servings.
Frequently Asked Questions
Can I make this shake in a regular blender?
Yes. Blend the ingredients in several smaller batches, then combine those batches in the large serving container.
Can I make the chocolate shake ahead of time?
It is best made close to serving time. When necessary, keep it covered in the refrigerator or surrounded by ice and stir it thoroughly before serving.
Why is my shake too thin?
The ice cream may have melted too much, or the mixture may contain too much milk. Blend in additional ice cream to thicken it.
How long can the shake sit out?
Keep this dairy-based shake properly chilled. Do not leave it at room temperature for more than two hours, or more than one hour in very hot conditions.
