Milkshake Guide – How to Get the Perfect Consistency

The perfect milkshake should be thick and creamy but still easy to drink through a straw. The ratio of ice cream, milk, flavouring and blend time controls the result.

A simple base formula

Start with around 2–3 scoops of vanilla ice cream and 100–150 ml cold milk per large serve. Begin with less milk and add more gradually until the texture is right.

Milkshake vs frappé

A classic milkshake is based on ice cream and milk, while café frappé more often uses ice cubes and a frappé base. Milkshake is therefore usually richer and more dessert-like. Read our frappé guide.

Why is my milkshake too thin?

• Too much milk.
• Too little ice cream.
• Ingredients too warm.
• Over-blending.
• Too much liquid syrup or purée.

Why is it too thick?

If the blender struggles or the shake will not pass through a wide straw, it usually needs a little more liquid. Add milk gradually.

Vanilla, chocolate and caramel

Vanilla is a good neutral base. Use Monin Chocolate Sauce or Monin Caramel Syrup for variations. Dose carefully because the ice cream already contributes plenty of sweetness.

Fruit milkshakes

Strawberry, mango and banana are classics. Fruit or purée adds liquid, so reduce milk slightly. The principles in our syrup vs purée guide are useful here too.

Which blender?

An efficient blender gives consistent texture. In professional service, cleaning, durability and speed matter. Browse our blenders.

Do you need crushed ice?

Usually not. A classic milkshake gets its cold temperature and structure from ice cream. Extra ice can make it thinner and less creamy.

Can you use frappé mix?

Yes as an alternative café method, though the result moves closer to a frappé. Monin Vanilla Frappé Mix is practical when speed and repeatability matter.

Glassware and service

A tall glass gives room for foam and garnish. A Caffè Latte glass or highball works well depending on serving size.

For professional cafés

• Portion ice cream consistently.
• Measure milk.
• Standardise syrup and sauce.
• Use a fixed blend time.
• Keep the same glass size.
