| Strawberry Shake | 74g |
The strawberry milkshake has the most sugar, with about 74 grams per shake.

In-N-Out Milkshake Ingredients: What Are They Made Of?
In-N-Out says its shakes are made with real ice cream.
The company does not publish a long detailed public ingredient list for every shake component in the same way some packaged foods do, but the core information is clear:
- In-N-Out shakes are dairy-based.
- They are made with real ice cream.
- The official flavors are vanilla, chocolate, and strawberry.
- They contain milk and are not dairy-free.
In-N-Out Milkshakes Allergens
The main allergen in all In-N-Out milkshakes is:
- Milk
Because the shakes are made with real ice cream, they are not dairy-free and not suitable for people avoiding milk.
Do In-N-Out shakes contain eggs?
In-N-Out’s standard allergen information identifies milk as the key allergen for shakes. If you have an egg allergy or a severe allergy, confirm with the restaurant directly before ordering, as ingredient sourcing and handling can change.
Do In-N-Out shakes contain nuts?
In-N-Out does not offer nut-based shake flavors like peanut butter or almond. However, customers with severe allergies should always confirm current allergen and cross-contact information with the restaurant.
Are In-N-Out Milkshakes Gluten Free?
In-N-Out milkshakes do not typically contain wheat-based ingredients, and the standard shake flavors are generally considered gluten-free by ingredient.
However, they are not certified gluten-free, and cross-contact can never be completely ruled out in a restaurant environment.
If you have celiac disease or a serious gluten sensitivity, ask the location for the most current allergen handling information before ordering.
