What is in Tropical Smoothie peanut butter cup?

One of their most popular options is the Peanut Butter Cup smoothie, which perfectly blends peanut butter and chocolate flavors into a creamy, frosty beverage. Customers love this smoothie for its rich, indulgent taste and nutritional benefits.

But what exactly goes into making Tropical Smoothie’s famous Peanut Butter Cup smoothie? The primary ingredients are peanut butter, chocolate, milk, yogurt, and ice, but the proportions and specific items used are key to recreating that signature Tropical Smoothie taste.

Read on to learn everything that is in a Tropical Smoothie Peanut Butter Cup smoothie and why each ingredient is important.

Peanut Butter

The star ingredient in Tropical Smoothie’s Peanut Butter Cup smoothie is peanut butter, which provides its nutty flavor, creamy texture, and protein content.

Tropical Smoothie uses conventional peanut butter containing just peanuts and salt in their Peanut Butter Cup smoothie. They likely use a commercial-grade peanut butter to ensure consistency across all stores. Many peanut butter brands contain extra ingredients like sugar, palm oil, and emulsifiers, but Tropical Smoothie opts for the simple stuff to let the peanuts shine.

Each 24-ounce Peanut Butter Cup smoothie contains around 3-4 tablespoons of peanut butter. This provides a good peanut flavor without overpowering the other ingredients. The natural oils in peanut butter also deliver creaminess and richness to balance out the frozen yogurt and ice.

Nutritional Benefits of Peanut Butter

In addition to its great taste, peanut butter packs a nutritional punch that makes it a smart addition to smoothies. Here are some of the top nutrients found in peanut butter:

– Protein – 2 tablespoons of peanut butter contains 7 grams of plant-based protein to help you feel full.

– Healthy Fats – Peanut butter provides heart-healthy monounsaturated and polyunsaturated fats.

– Fiber – A serving of peanut butter has 2 grams of dietary fiber for digestive health.

– Vitamin E – Peanut butter is high in antioxidant vitamin E.

– Magnesium – Peanut butter contains 86 mg magnesium per serving to support bone, muscle, and nerve function.

– Potassium – With 208 mg potassium per serving, peanut butter may help lower blood pressure.

So peanut butter adds great nutrition as well as flavor to the Peanut Butter Cup smoothie. The protein, fiber, vitamins, and minerals make this smoothie a satisfying mini meal.

Chocolate Syrup

What pairs better with peanut butter than chocolate? Tropical Smoothie uses chocolate syrup in their Peanut Butter Cup smoothie to provide a rich, cocoa taste and creamy texture.

The chocolate syrup contains cocoa powder and cocoa butter along with sugar and preservatives. It likely has a higher sugar content than most homemade chocolate sauces. But a small amount of chocolate syrup gives the Peanut Butter Cup smoothie a delicious chocolate flavor without overloading it with sweetness.

Each 24-ounce smoothie gets around 1-2 tablespoons of chocolate syrup. This strikes the right balance between peanut butter and chocolate. Too much chocolate would overpower the peanut butter, but the right amount adds perfect complementary flavor.

The chocolate syrup also incorporates smoothly into the drink thanks to its liquid form. Chocolate powder or shavings might give uneven chocolate distribution, but syrup blends seamlessly into the liquid ingredients.

Nutrition Benefits of Cocoa

Cocoa is the key ingredient in chocolate that lends its various health benefits. Here is an overview of the nutrients found in the cocoa used to make chocolate syrup:

– Antioxidants – Cocoa is loaded with polyphenols and flavanols that act as antioxidants in the body.

– Fiber – Cocoa powder provides dietary fiber, with about 1 gram per tablespoon.

– Iron – Cocoa contains high levels of iron to support healthy blood and oxygen supply.

– Magnesium – With 64 mg per ounce, cocoa is one of the best food sources of magnesium.

– Zinc – Important for immune function, cocoa provides zinc.

So while chocolate syrup does contain sugar, the cocoa it is made from still imparts some great nutritional value. The antioxidants and minerals make the Peanut Butter Cup smoothie not just a treat, but a healthy choice.


Milk is the primary liquid ingredient in Tropical Smoothie’s Peanut Butter Cup smoothie. Milk provides hydration, creaminess, calcium, and protein.

Tropical Smoothie likely uses 2% reduced-fat dairy milk in their smoothies. Whole milk would provide greater creaminess, but 2% milk has significant fat and calories reduced. Skim milk is too watery, but 2% hits a nice balance.

The milk not only supplies moisture but also gives a creamy, frothy texture. The natural sugars and proteins in milk help thicken up the drink. This balances against the crunchy ice for a smooth, even consistency.

About 16-20 ounces of milk go into a 24-ounce Tropical Smoothie smoothie. This ensures the beverage is not too thick but still packs nutrition. The milk provides a good amount of:

– Calcium – for strong bones and nerve function

– Vitamin D – for calcium absorption and immunity

– Protein – to help satisfy hunger

– Potassium – to control blood pressure

Overall, milk makes for a nutritious liquid base that complements the flavors of peanut butter and chocolate wonderfully.

Vanilla Yogurt

Tropical Smoothie adds a dollop of vanilla yogurt to their Peanut Butter Cup smoothie too. The yogurt provides creaminess, protein, and a tangy flavor.

The yogurt is likely a low-fat or non-fat Greek yogurt. Greek yogurt is thicker than regular yogurt, making it ideal for smoothies. Non-fat yogurt keeps the thickness while avoiding excess saturated fat.

About 4-6 ounces of yogurt go into a 24-ounce Peanut Butter Cup smoothie. This gives a good protein boost without excessive tanginess. Too much yogurt could make the drink sour.

The live active cultures in yogurt provide probiotics for digestive and immune health. And yogurt made from milk supplies extra calcium and protein. Just a few ounces of yogurt can make a big nutritional difference and add creaminess.

Vanilla yogurt also has a milder flavor than other fruit-flavored yogurts. This allows the rich peanut butter and chocolate to remain the star flavors rather than competing against strawberry or blueberry yogurt. But vanilla yogurt still adds depth and a pleasant dairy taste.


What turns all the ingredients above into a frosty smoothie? Shaved ice of course! Crushed ice is essential for achieving Tropical Smoothie’s signature thick, cold texture.

Tropical Smoothie likely uses a special machine to finely shave ice for their smoothies. Normal ice cubes don’t blend up as smoothly. The tiny ice crystals incorporate easily into the drink.

About 2-3 cups of ice go into a 24-ounce Peanut Butter Cup smoothie. Too much would dilute the flavor, but this amount makes it frosty and refreshing. The ice also instantly chills the drink for that icy cold feeling.

While ice may seem like just a filler ingredient, it significantly impacts the mouthfeel of the smoothie. Finely shaved ice makes it light and almost fluffy compared to a dense, icy beverage with larger chunks.

So ice is just as important as the other components when it comes to nailing the ideal smoothie consistency. It ties everything together into a chilled treat.

Possible Other Ingredients

In addition to the core ingredients above, Tropical Smoothie’s Peanut Butter Cup smoothie likely contains some other supplemental items to finish the recipe:

– Cocoa powder – for extra chocolate flavor

– Vanilla extract – to enhance vanilla notes

– Salt – a pinch to balance sweetness

– Stabilizing gum – prevents separation and thickness

– Sugar – if needed to sweeten

Tropical Smoothie aims for a proprietary blend of flavors in all their smoothies. So their exact recipe for peanut butter cup remains a secret. But minor amounts of the above ingredients help lend that signature taste customers love.

Ingredients to Avoid

Just as important as knowing what’s in Tropical Smoothie’s Peanut Butter Cup smoothie is knowing what isn’t. Here are some ingredients you won’t find:

– Artificial sweeteners

– Artificial flavors or colors

– Preservatives

– High fructose corn syrup

Tropical Smoothie uses no artificial additives or extra sweeteners. Their smoothies feature all natural, high quality ingredients. This allows the true flavors to shine through.

The peanut butter cup is sweetened primarily with sugar contained in the chocolate syrup, milk, and yogurt. By avoiding artificial sweeteners, they create an end product that tastes homemade.

Allergy Information

Since a Tropical Smoothie peanut butter cup contains dairy, peanuts, and cocoa, those with allergies need to be aware. Here are the allergen details:

– Contains milk – Those with dairy/lactose allergy or sensitivity should avoid

– Contains peanuts – Not safe for those with peanut/tree nut allergies

– Contains chocolate/cocoa – The chocolate syrup presents risk to those with chocolate allergy

Tropical Smoothie likely processes peanuts and chocolate in their facilities. So there is a risk of cross-contamination even in their non-peanut, chocolate-free smoothies.

If food allergies are a concern, check Tropical Smoothie’s allergen information online or request details from a staff member before ordering. Customers with severe food allergies may want to avoid Tropical Smoothie due to potential cross-contamination.
