Classic Vanilla Milkshake
A thick, creamy diner-style vanilla milkshake made with just three ingredients and a blender. The right ice cream-to-milk ratio gives you a shake you can sip through a straw but still eat with a spoon.

Steps
Before you start
- Put two tall glasses in the freezer 10 minutes ahead so the shakes stay cold and thick longer.
- Keep the ice cream frozen solid until the moment you blend. Soft or melted ice cream makes a thin shake.
- Use the milk straight from the refrigerator. Cold milk keeps the shake thick.
- Measure everything before you start, because the blending takes less than a minute.
Chill the glasses
- Place two tall glasses (12–14 oz / 355–400 ml) in the freezer for at least 10 minutes while you gather and measure the other ingredients.

Ready when: Glasses feel cold and slightly frosty to the touch
Tip: Do this first, since it is the only step that needs waiting time.
Measure the milk and vanilla
- Measure ¾ cup (180 ml) cold whole milk and 1 teaspoon (5 ml) vanilla extract.
- Pour both into the blender jar first.
- Liquid at the bottom helps the blades catch the ice cream.

Tip: Adding the liquid first prevents air pockets around the blades.
Scoop the ice cream
- Scoop about 3 cups (420 g, roughly 6 large scoops) of frozen-solid vanilla ice cream straight from the freezer into the blender, on top of the milk.

Ready when: Ice cream sits in the jar in large, firm scoops
Tip: If the ice cream is rock hard, dip the scoop in hot water first. Don't let the ice cream soften on the counter.
Blend until smooth
- Secure the lid.
- Blend on low for 5 seconds to break up the scoops, then increase to medium-high and blend for 15–25 seconds.
- Stop as soon as the mixture is smooth.

Ready when: No lumps remain and a thick vortex forms in the center of the jar. The shake should slowly fall off a spoon in a ribbon.
Tip: Over-blending warms and thins the shake. If the blades spin without pulling in the mixture, stop and push it down with a spatula, then blend 5 seconds more.
Adjust the thickness
- If the shake is too thick to blend or sip, add 1 tablespoon (15 ml) cold milk and pulse 2–3 times.
- If it is too thin, add 1 large scoop of ice cream and pulse until just combined.

Ready when: Shake is thick but can be pulled up a wide straw
Tip: Make adjustments in small amounts, because a little milk changes the texture a lot.
Pour and serve
- Take the glasses from the freezer and divide the shake evenly between them.
- Top each with whipped cream if you like, add a wide straw and a long spoon, and serve immediately.

Ready when: Glasses are filled with a thick shake that holds a soft peak at the top
Tip: Serve right away. The shake starts to thin within about 5 minutes.
Good to know
Tips
- The ratio is about 4 parts ice cream to 1 part milk by volume. For a thicker shake, start with 2 tablespoons (30 ml) less milk.
- Choose a vanilla ice cream with a short ingredient list and real vanilla. It is the main flavor, so quality shows.
- Use a blender jar that is not warm from earlier use. A cold jar helps the shake stay thick.
- For a malted version, add 2 tablespoons (about 15 g) malted milk powder before blending.
Make ahead
Milkshakes are best made fresh. For a head start, scoop the ice cream into the blender jar, cover, and freeze up to 1 hour. Add the cold milk and vanilla right before blending.
Storage & reheating
Best served immediately. Room temperature: do not hold more than 5 minutes. Fridge: not recommended. Freezer: pour leftovers into a lidded freezer-safe jar and freeze up to 1 week. To reuse, let it sit 5 minutes, then re-blend with 2 tablespoons (30 ml) cold milk until smooth.
Substitutions
- whole milk → 2% milk, oat milk, or half-and-half. 2% or oat milk gives a slightly lighter shake. Half-and-half gives a richer one, so use 2 tablespoons (30 ml) less.
- good-quality vanilla ice cream → dairy-free vanilla frozen dessert. Use a creamy oat or coconut-based one and pair it with oat milk. The shake may be a little softer, so use 2 tablespoons (30 ml) less milk.
- pure vanilla extract → 1 teaspoon (5 ml) vanilla bean paste. Gives visible vanilla specks and a stronger flavor.
- whipped cream → a drizzle of chocolate syrup or a maraschino cherry. Optional garnishes for a classic soda-fountain look.
