When Is National Vanilla Milkshake Day Celebrated?
National Vanilla Milkshake Day is celebrated every year on June 20. The date does not shift or rotate, it is a fixed annual observance. [4] [9]
In 2026, June 20 falls on a Saturday, making it an ideal day to visit a local diner, fire up the blender at home, or take the family out for a cold treat. The timing is well-placed: June 20 often coincides with the summer solstice, the longest day of the year in the Northern Hemisphere, so the holiday pairs naturally with warm-weather celebrations.
Why Is June 20 National Vanilla Milkshake Day?
The specific reason June 20 was chosen as National Vanilla Milkshake Day is not documented in any single official founding record. Like many food holidays in the United States, it appears to have grown organically through food bloggers, social media communities, and national day tracking organizations rather than through a formal government or industry proclamation. [3] [4]
What makes the date fitting is its placement at the edge of summer. June 20 sits right at or near the summer solstice, a time when cold, creamy drinks are in high demand. The holiday’s timing reinforces the association between milkshakes and warm-weather enjoyment.
The National Day Calendar confirms June 20 as the recognized date for this observance. [6]
Vanilla Milkshake History and Origin
The milkshake has a longer history than most people expect. The term “milkshake” appeared in print as early as 1885, though those early versions were closer to an eggnog-style drink that sometimes included whiskey. By the early 1900s, the word had shifted to describe a sweet, frothy drink made with milk and flavored syrups.
The modern blended milkshake, the thick, ice-cream-based version most people recognize today, became widespread after the invention of the electric blender in the 1920s. Diners and soda fountains across the United States quickly adopted the blended milkshake as a menu staple, and vanilla became one of the defining flavors alongside chocolate and strawberry.
Vanilla’s popularity in milkshakes tracks directly with its status as a top-selling ice cream flavor. The combination of a neutral, creamy base with the floral warmth of vanilla extract or vanilla bean creates a flavor that pairs easily with other foods, which is part of why vanilla milkshakes became a diner classic served alongside burgers and fries.

How to Make the Best Vanilla Milkshake at Home
A great vanilla milkshake at home requires just three core ingredients and about five minutes. The key is using quality vanilla ice cream and the right milk-to-ice-cream ratio.
Classic Vanilla Milkshake Recipe with Ice Cream
Ingredients:
- 3 large scoops (about 1.5 cups) of premium vanilla ice cream
- 1/2 cup whole milk (adjust for desired thickness)
- 1/2 teaspoon pure vanilla extract (optional, enhances flavor)
- Whipped cream and a cherry for topping (optional)
Steps:
- Let the ice cream sit at room temperature for 2 to 3 minutes to soften slightly.
- Add milk to the blender first, then add ice cream scoops.
- Add vanilla extract if using.
- Blend on medium speed for 20 to 30 seconds until smooth and thick.
- Pour into a chilled glass and top with whipped cream if desired.
- Serve immediately.
Pro tips:
- Chilling the glass in the freezer for 10 minutes before pouring keeps the shake cold longer.
- Use a 3:1 ratio of ice cream to milk for a thick shake; increase milk for a thinner consistency.
- Vanilla bean paste delivers a more intense flavor than standard extract and adds visible bean specks.
Can You Make a Vanilla Milkshake Without Ice Cream?
Yes, a vanilla milkshake without ice cream is achievable and can still be rich and satisfying. The most effective method uses frozen banana as a base, which mimics the thick, creamy texture of ice cream when blended.
No-ice-cream method:
- 2 frozen bananas, sliced
- 1 cup cold whole milk or oat milk
- 1 teaspoon vanilla extract
- 2 tablespoons honey or maple syrup (to taste)
- Pinch of salt
Blend until completely smooth. The result is thicker than a standard milkshake and slightly sweeter, with a naturally creamy texture.
Another option: blend 1 cup of frozen vanilla yogurt with 1/2 cup milk for a lower-fat alternative that still delivers a milkshake-like result.
What Milk Is Best for Vanilla Milkshakes?
Whole milk is the best choice for a classic vanilla milkshake because its higher fat content (3.25%) creates a richer, creamier texture and helps the shake hold together without becoming watery. Lower-fat milks can work but often produce a thinner, less satisfying result.
| Milk Type | Fat Content | Result in Milkshake |
|---|---|---|
| Whole milk | 3.25% | Richest, creamiest, classic texture |
| 2% milk | 2% | Slightly thinner, still good |
| Skim milk | 0% | Watery, not recommended |
| Oat milk | Varies | Creamy, mild flavor, good dairy-free option |
| Coconut milk (canned) | High | Very rich, adds coconut note |
| Almond milk | Low | Thinner, mild nutty flavor |
Choose oat milk if you want a dairy-free shake with a neutral flavor that does not compete with vanilla. Choose canned coconut milk if you want extra richness and don’t mind a subtle coconut undertone.
Vegan Vanilla Milkshake Recipe
A vegan vanilla milkshake skips dairy entirely without sacrificing creaminess. The best results come from using coconut-milk-based vanilla ice cream, which is widely available in most grocery stores.
Vegan vanilla milkshake:
- 3 scoops coconut milk vanilla ice cream (or cashew milk vanilla ice cream)
- 1/2 cup oat milk or full-fat coconut milk
- 1 teaspoon pure vanilla extract
- Optional: 1 tablespoon maple syrup for extra sweetness
Blend until smooth. Coconut milk ice cream tends to freeze harder than dairy ice cream, so let it soften for 3 to 4 minutes before blending.
For those with nut sensitivities, oat milk ice cream brands are a safe alternative and blend well with oat milk for a fully oat-based shake.
Vanilla Milkshake vs. Chocolate Milkshake: Key Differences
Vanilla and chocolate milkshakes are the two most ordered milkshake flavors in the United States, and they differ in more than just taste.
Vanilla milkshake characteristics:
- Lighter, floral flavor profile
- Pairs well with savory foods like burgers and fries
- Easier to customize with mix-ins (fruit, caramel, cookie pieces)
- Generally slightly lower in calories than chocolate versions
Chocolate milkshake characteristics:
- Richer, more intense flavor
- Higher sugar content when cocoa syrup or chocolate sauce is added
- Stronger standalone flavor that can overpower food pairings
- More filling due to cocoa’s slight bitterness cutting sweetness
Choose a vanilla milkshake if you want a versatile base that works well with toppings and food pairings. Choose chocolate if you want a bold, standalone dessert drink.

How Many Calories Are in a Vanilla Milkshake?
Calorie counts in vanilla milkshakes vary significantly based on size, ingredients, and whether whipped cream or toppings are added.
General estimates (not brand-specific):
- Small homemade shake (8 oz, whole milk + 2 scoops ice cream): approximately 350 to 400 calories
- Standard restaurant shake (16 oz): approximately 500 to 700 calories
- Large fast-food shake (20 to 24 oz): approximately 700 to 900 calories
- Vegan coconut milk shake (12 oz): approximately 300 to 450 calories
The biggest calorie drivers are ice cream fat content, added sugar (syrups, whipped cream), and portion size. Using reduced-fat ice cream and 2% milk can bring a homemade shake down to roughly 250 to 300 calories for a 10 oz serving.

FAQ
Q: Is National Vanilla Milkshake Day an official U.S. holiday? No. It is an informal food observance, not a federal or state holiday. It is not recognized by the U.S. government but is widely observed through social media, restaurant promotions, and food community calendars.
Q: Does National Vanilla Milkshake Day change dates each year? No. It is always June 20, every year. The date does not shift based on the day of the week.
Q: What is the difference between a milkshake and a malt? A malt (or malted milkshake) includes malted milk powder in addition to ice cream and milk. This adds a slightly nutty, toasty flavor. A standard milkshake does not contain malt powder.
Q: Can lactose-intolerant people celebrate National Vanilla Milkshake Day? Yes. Lactose-free ice cream and plant-based milks (oat, coconut, almond) make it easy to prepare a dairy-free vanilla milkshake without sacrificing much flavor or texture.
Q: What is the best vanilla ice cream brand for milkshakes? Premium brands with higher butterfat content (such as Haagen-Dazs or Tillamook) produce the creamiest results. Store-brand ice creams with added air (higher overrun) tend to produce thinner shakes.
Q: How long does a homemade vanilla milkshake last? Milkshakes are best consumed immediately. If stored in the freezer, they can last up to 2 hours before the texture degrades, but they will need re-blending. Refrigerating a shake causes it to separate and become watery.
Q: Are there savory vanilla milkshake variations? Some culinary experiments combine vanilla with unexpected ingredients like black pepper, lavender, or sea salt for a sweet-savory profile. These are niche variations and not traditional, but they are popular in artisan dessert shops.
Q: What is the origin of the word “milkshake”? The word appeared in American print as early as 1885. Early uses referred to a whiskey-based drink. By the early 1900s, the term had shifted to describe a non-alcoholic sweet milk drink, and by the 1920s it referred to the blended ice cream version known today.
