The Secret In-N-Out Milkshake You Should Know About

Picture this: You're out-and-about on your usual Saturday afternoon errands when all of a sudden your midday hunger starts to kick in. Sure, you could throw the flag in early and call it a day, or you could make a stop at your local In-N-Out to revive your spirits to finish off your productive day strong. The latter sounds like a better idea, especially knowing burgers, fries, and milkshakes will be involved.

Since opening its doors in 1948, In-N-Out has expanded to over 344 locations throughout six states, including California, Nevada, Arizona, Utah, Texas, and Oregon (via In-N-Out). If you don't reside in one of the above-mentioned states, we hate to rub it in your face, but you truly are missing out. From its delicious burgers, crispy fries, and old-fashioned milkshakes, In-N-Out is one of the most iconic fast-food burger joints in the United States.

If you're lucky enough to live close to one of its locations, you've probably nailed down your order by now. But what's the point of going out to eat if you don't take some chances and order something new? Maybe you're one to always order a vanilla milkshake with your order. That's great and all, but leaving chocolate and strawberry behind should be criminal. Thankfully, there's actually a secret In-N-Out milkshake that allows you to combine all three flavors.

Can't decide between getting a chocolate, vanilla, or strawberry milkshake? No problem. Like many other chain restaurants, In-N-Out actually has a "secret menu" that allows customers-in-the-know access to some pretty cool food creations. Among In-N-Out's secret menu is the "secret" milkshake that allows you to combine all three milkshake flavors into one. Sound familiar? Yeah, this is called Neapolitan.

According to Hack The Menu, the In-N-Out Neapolitan milkshake is actually a popular "secret menu" item that gets ordered quite frequently. For those of you just finding out about this amazing milkshake combination, at least now you know.

This can also be applied if you're wanting just two of the flavors: chocolate-vanilla, chocolate-strawberry, or vanilla-strawberry. With four new possible "secret" milkshakes, your next outing at In-N-Out is sure to be a good one. You might even influence other people in line behind you to try it out, making it not so secret.

If you were shocked to learn about the secret In-N-Out Neapolitan milkshake, hold onto your hats, folks. There's actually over a dozen different "unofficial" and "secret" menu items that you can order at your local In-N-Out to give you some new variety to your usual order (via Enjoy Orange County). If you enjoy some more meat with your burger, try ordering a 3x3 or 4x4, which of course implies the number of beef patties that comes between the burger buns. You can also order any burger and sandwich "protein style," which will make it come wrapped in lettuce instead of that gluten-based bun. Have your dog with you in the drive-thru? Order a Scooby Snack and you can treat your furry friend to a plain one-burger patty.

The same goes for more sweet drinks and treats at the burger joint. You can order "secret" floats at In-N-Out, the easiest being a root beer float. Love iced tea and In-N-Out's pink lemonade? There's an Arnold Palmer or "Tea Ade" that can get you both.
