Does Smoothie King Have a Secret Menu?

Yes, absolutely! While you won’t find it printed on a sub-menu hidden behind the counter, the Smoothie King secret menu is fairly well-known among fans and even staff. It’s made up of viral combinations and the most popular customer hacks.

These items are shared on online forums and social media, with each Smoothie King secret menu drink made by creatively tweaking the chain’s wide range of ingredients to make a new and unique flavor. 

With over 75 ingredients to choose from (plus rotating seasonal specials like pumpkin spice and blossom flowers), the official Smoothie King menu is packed with flavors to create one-of-a-kind orders. 

You can customize your drink however you like, but the charm of the Smoothie King secret menu is that these items have been tried and tested by countless fans first. In other words, think of the secret menu at Smoothie King as a shortcut to the best customer-approved combos without the trial and error.

How We Created This Smoothie King Secret Menu Guide

We don’t take shortcuts at Cozymeal when we’re researching secret menus. Creating this Smoothie King secret menu guide wasn’t just a matter of throwing together a few flavors and hoping for the best. 

We dug through fan forums, food community boards and viral videos to see where smoothie lovers were sharing their most reliable creations. From there, we compared the most popular ideas against Smoothie King’s current ingredient list to make sure every recipe was still possible to order today. 

Above all, we set out to create a guide to the Smoothie King secret menu that showcases a good balance of decadent treats and healthier drinks. We also highlight those that require only small tweaks to regular menu items, as well as full-blown custom orders. 

By filtering out the impossible requests and spotlighting the most beloved combinations, we’ve built a resource you can actually use the next time you join the queue. 

The 10 Best Smoothie King Secret Menu Items

1. Peanut Butter & Jelly 

If you’ve had a long day and you need a little pick-me-up to make everything better or are looking for treat-style breakfast food ideas, there are few joys on Earth like the nostalgic duo of peanut butter and jelly.

In this Smoothie King secret menu drink, creamy peanut butter is blended with diced strawberries and banana to make a rich and fruity sip that tastes like childhood lunches in drink form. 

Thanks to the all-natural fruits, you don’t need any additional sweetness in this Smoothie King secret menu order, and the texture is thick while still sippable. Choose almond milk or oat milk for the base, then, if you really like it sweet, add honey or turbinado depending on your preference. 

This drink is proof that the secret menu at Smoothie King isn’t just new ideas and flavors — it also takes old-school classics and makes them into something portable, refreshing and surprisingly satisfying after a workout. 

How To Order

• Peanut Butter
• Diced Strawberries
• Bananas 
• Almond Milk or Oat Milk
• Honey or Turbinado (optional)

2. Chocolate Covered Strawberry

Looking for decadent Smoothie King secret menu drinks that are basically dessert in a cup? Well, there’s no better choice than this chocolate-covered strawberry smoothie. 

Diced strawberries give this drink a bright and fruity base, while the Gladiator Protein Chocolate (or Lean1 Chocolate) brings rich, chocolatey depth. While it sounds a little decadent, we found that it wasn’t cloying at all. Instead, it’s the kind of smoothie that feels like a treat without completely food-comatosing you. 

What sets this Smoothie King secret menu option apart from the others on this list is how easy it is to adapt to your favorite flavors. Substitute the chocolate powders for a spoonful of 100% cocoa to make it darker and more luxurious, or add some honey to soften the bitterness. 

The Smoothie King secret menu thrives on taking familiar pairings and giving them a functional spin, and this is one of the best examples. 

How To Order 

• Diced Strawberries
• Gladiator Protein Chocolate or Lean1 Chocolate Protein
• Greek Non-Fat Yogurt
• Cocoa (optional)
• Honey (optional)

3. Strawberry Shortcake

The Smoothie King secret menu doesn’t shy away from popular dessert flavors, and this shortcake-inspired blend is one of the best at mimicking its namesake. 

We love how the inclusion of granola resembles the classic shortcake crumb. Alongside this,  fresh strawberries provide the fruitiness, and vanilla frozen yogurt, combined with a splash of almond milk, creates a creamy taste. 

This smoothie is light yet indulgent, capturing all the best parts of strawberry shortcake without needing a fork. If you don’t like granola, turbinado gives this drink a similar crumbly note, and it comes with the added bonus of making it a little sweeter, too. 

Plus, you can always ask for protein powder or fiber blend to make this Smoothie King secret menu drink feel more like a complete meal than just a cheeky dessert before noon.

How To Order

• Strawberries
• Vanilla Frozen Yogurt
• Almond Milk or Almond Vanilla Blend
• Purely Elizabeth Granola or Turbinado

4. Banana Split

While Smoothie King definitely ranks as one of the healthiest fast food chains out there, sometimes you need something a little more… extravagant. While looking into the Smoothie King secret menu, we found that some of the most highly ranked orders were those that reimagined retro desserts, and this banana split-inspired concoction fit the bill perfectly. 

Bananas and diced strawberries provide the fruity foundation, while Gladiator Protein Chocolate (or 100% cocoa) layers in richness. Vanilla frozen yogurt ties it all together. The result is a creamy, classic sundae that is so good you won’t even need hot fudge or a cherry on top.

If you’re looking for decadence over nutrition, we recommend swapping the froyo for butter pecan ice cream. Either way, this is one of the most fun Smoothie King secret menu creations out there. But be careful: once you’ve tried it, it’ll be hard to find a better flavor ever again! 

How To Order

• Bananas
• Diced Strawberries
• Gladiator Protein Chocolate or 100% Cocoa
• Vanilla Frozen Yogurt or Butter Pecan Ice Cream

5. Piña Colada

Reminiscing about your summer holidays and need a tropical smoothie that transports you to slow days and sandy beaches? Then you’ll love the piña colada smoothie straight from the Smoothie King secret menu! 

Pineapple gives it brightness, coconut sorbet and shredded coconut add a creamy body, and coconut water lends a silky smooth texture that turns this drink into a breezy refresher. This smoothie is not overly sweet and coconut water also adds some electrolytes like potassium and magnesium. 

Tart and creamy, this piña colada smoothie is an instant pick-me-up, even without the rum. If you want an even fruitier flavor, the pineapple mango refresher base is an excellent addition. Few Smoothie King secret menu drinks can encapsulate that classic tropical flavor without tipping into candy-sweet, and that balance is exactly what makes this smoothie one of our absolute favorites. 

How To Order

• Pineapple
• Coconut Sorbet
• Shredded Coconut 
• Coconut Water
• Pineapple Mango Refresher (optional) 

6. Blueberry Cheesecake

Can you see a theme with these Smoothie King off-menu items yet? SK fans are especially hooked on the dessert-to-smoothie crossovers, and the Blueberry Cheesecake Smoothie might just be the crown jewel of the Smoothie King secret menu. 

Blueberries form the fruity backbone of this smoothie, while vanilla froyo and Greek non-fat yogurt give it that cheesecake tang and creaminess. Honey ties it all together with its natural sweetness and if you want a crunchy texture like the graham cracker crumb of a cheesecake, you can always add granola. 

Gladiator Protein Vanilla or whey protein is also a great addition to this Smoothie King secret menu order, making it higher in protein, which will help keep you feeling full for longer. 

The richness of the smoothie is balanced by the tartness of the blueberries, creating a drink that tastes indulgent while not being too heavy. Cheesecake lovers will find this Smoothie King secret menu trick dangerously addictive and we’re already looking forward to the next time we get to order it.

How To Order 

• Blueberries
• Vanilla Frozen Yogurt
• Greek Non-Fat Yogurt 
• Honey
• Gladiator Protein Vanilla or Whey Protein (optional)

7. Almond Joy

If you’re not feeling a full-on dessert vibe and you’d prefer to order some healthy drinks that still taste like a treat (like one of the best chocolate bars, in this case), we recommend getting an Almond Joy from the Smoothie King secret menu. It channels candy-bar energy but with a healthy twist. 

Shredded coconut provides the tropical sweetness, while almonds (or almond butter) add a nutty richness. 100% cocoa and whey protein (or Gladiator Protein Chocolate if you prefer) give the drink a chocolatey base. The result is a surprisingly balanced smoothie that isn’t too sweet or candy-flavored but still mimics the flavor profile of the namesake chocolate bar. 

How To Order

• Shredded Coconut or Coconut Sorbet
• Almonds or Almond Butter
• 100% Cocoa 
• Whey Protein or Gladiator Protein Chocolate
• Sweetened Cacao Nibs 
• Vanilla Frozen Yogurt

8. Apple Pie

Feeling fall flavors all year long? Or perhaps you’re craving a nostalgic apple pie but want to try it in drink form? Either way, this beverage from the Smoothie King secret menu is a fantastic option. 

Apple juice blend gives this drink that classic fruit-forward sweetness with no extra sugar needed, while cinnamon (or spice blend) and vanilla frozen yogurt bring that warmth and hint of spice you’ll find in fresh-out-the-oven apple pies. 

The result? The perfect apple pie filling flavor, but in a refreshing Smoothie King secret menu drink. And if you don’t want to stop at just apple pie filling, you can also add Purely Elizabeth granola for that crust-like crunch. 

How To Order

• Apple Juice Blend or Apple Blueberry
• Cinnamon or Spice Blend
• Vanilla Frozen Yogurt 
• Oat Milk or Almond Milk
• Purely Elizabeth Granola 

9. Strawberry Lemonade Smoothie

While it’s true that the Smoothie King secret menu leans heavily on reimaged dessert ideas, it also has some great, refreshing options. The Strawberry Lemonade Smoothie is bright and fruity, offering a welcome hit of refreshment on a hot day or after an intense gym session.

Strawberries provide sweetness, while the white grape lemon juice blend gives it a citrusy kick that tastes sharp and refreshing. You can also opt to add electrolytes to it, resulting in a drink that seriously has some pep in its step. Coconut water or regular water keeps it light and drinkable. 

Some might not think this drink is sweet enough, so fans also recommend adding stevia or turbinado to dial up the sweetness. However you choose to customize this Smoothie King secret menu order, you'll get a cup of fresh deliciousness. 

Unlike some of the heavier options on this list of the Smoothie King secret menu drinks, this one is all about refreshment. Bright, balanced and absolutely well worth repeating.

How To Order

• Diced Strawberries
• White Grape Lemon Juice Blend
• Water or Coconut Water 
• Stevia or Turbinado (if desired)

10. Chocolate Cacao Nib Crunch Smoothie

For those who like a little texture — or in this case, a lot of texture — the entry on our list of the best Smoothie King secret menu offerings is sure to be your favorite.

The chocolate Cacao Nib Crunch Smoothie is made from Gladiator Protein Chocolate for a chocolatey base, while Greek non-fat yogurt and almond milk give the drink a silky body. 

Sweetened cacao nibs lend it that satisfying chip-like crunch, and this balance of bitterness with sweetness reminds us of double chocolate chip cookies in all the right ways. While it sounds quite sweet, this order is indulgent without tipping into over-the-top, sickly sweet.

Interestingly, we found it leans more on the bitter side, which is perfect for those who want a drink from the Smoothie King secret menu that’s not too sweet. If you're craving chocolate with a bit of bite, this is the one.

How To Order

• Gladiator Protein Chocolate or 100% Cocoa and Protein Blend
• Greek Non-Fat Yogurt
• Almond Milk 
• Sweetened Cacao Nibs

How To Order From the Secret Menu at Smoothie King

Ordering from the Smoothie King secret menu isn’t like ordering from the regular offerings — it takes a little more patience and some prep ahead of time, so you know exactly what you want when you get to the counter.

The benefit of ordering from the secret menu at Smoothie King is that the chain already offers customizations and add-ons, so it’s much easier to request custom creations than at many other places. 

To order from the Smoothie King secret menu, you’ll need to build your drink by choosing a base flavor, adding mix-ins like fruit, yogurt or nut butters, and then deciding on optional supplements. Protein powders, probiotics, antioxidants, extra fiber, energizers or electrolytes are all fair game, depending on what you want from your smoothie.

It’s worth bearing in mind that the Smoothie King secret menu is unofficial, so not every staff member may recognize your request right away if you call it by its name, like Blueberry Cheesecake or Almond Joy. 

It’s best to arrive with the exact ingredients that make up the smoothie, which we’ve provided with each beverage listed above. If ordering online, just make a custom order and add the ingredients we’ve listed in the How To Order section, adding or removing things to match your preferences.

Don’t forget to also be polite to staff and show gratitude for them taking the time to make your custom order. For the best experience, try visiting during non-peak hours when staff have more time to customize your blend and have a few back-up ideas ready if certain ingredients are out of stock. By approaching the Smoothie King secret menu with a little flexibility, you’ll increase your chances of walking away with exactly what you want.

How To Get a Free Smoothie at Smoothie King

The Smoothie King secret menu may be unofficial, but getting a free smoothie is very much real. All you need to do is join the Healthy Rewards program by downloading the Smoothie King app. New members often get a sign-up bonus like a free smoothie, plus you’ll earn points on every purchase that can be redeemed later. On Fridays, you can even upgrade your smoothie size for free.

The best part? Every year, you can get free birthday food (or drink!) as members of the rewards program get a complimentary smoothie on their special day.

Between these perks and all the ongoing promotions, the Healthy Rewards program pairs perfectly with the Smoothie King secret menu — you can try creative blends every time you order, all while scoring deals along the way.

From nostalgic PB&J blends to tropical piña coladas and candy-bar-inspired customizations, the Smoothie King secret menu is a great example of how there’s so much more to try at these fast food joints than what’s shown on the menu boards. 

With the right insider knowledge, you actually never have to order from the main menu ever again — just try a few combos, note down your favorites and order from the Smoothie King secret menu every time you’re there.
