Do Arby’s Jamocha Shakes Have Caffeine? – Barista HQ

As soon as I took my first sip of a Jamocha Shake from Arby’s, I was hooked.

While I’ve never considered myself a frequent customer at this fast food restaurant, that all changed with Arby’s Jamocha Shake.[1]

The combination of coffee and chocolate flavors in this frosty beverage makes it a refreshing choice, especially on hot summer days.

Like most things at Arby's, the Jamocha Shake isn't a health-oriented option.

I knew immediately that it was packed with calories and sugar content. As I was sipping, I wondered, do Jamocha Shakes have caffeine?

In this guide, I’ll cover everything there is to know about Arby’s Jamocha Shake, including ingredients, copycat recipes, and caffeine content.

Both coffee and chocolate contain caffeine, so it’s easy to assume that the Jamocha Shake, which contains both, would be highly caffeinated, but there is very little caffeine in Arby’s Jamocha Shake.

Unlike many frozen coffee beverages that use espresso, concentrated brewed coffee, or coffee concentrate, this one is made with instant coffee powder, which has a much lower caffeine content.

After a bit of research, I found out that Arby’s Jamocha Shake contains just 0.72mg of caffeine per ounce. Here’s the serving size caffeine breakdown based on the size you order:

  • 8.7 mg of caffeine in the small Jamocha Shake (12oz)
  • 11.6 mg of caffeine in the medium Jamocha Shake (16oz)
  • 16 mg of caffeine in the large Jamocha Shake (22oz)

Compared to a Starbucks Frappucino, that's a minimal amount of caffeine. A grande Frapp at Starbucks has 100 mg of caffeine, and it's even more with an espresso Frappuccino.

It's no wonder I'm so jittery after drinking one of those!

All About Arby's Jamocha Shake (Nutritional Breakdown)

Now that you know how much caffeine is in Arby’s Jamocha Shake, it’s time to focus on its other nutritional aspects.[2]


There’s a long list of ingredients that help to create the creamy texture, including:

  • Vanilla Shake Mix (whole milk, sugar, high fructose corn syrup, nonfat milk, grade A sweet whey, cream, natural vanilla flavor, mono and diglycerides, cellulose gum, guar gum, carrageenan, dipotassium phosphate, sodium citrate, sodium chloride, sodium carbonate, annatto, caramel color)
  • Jamocha Syrup (high fructose corn syrup, water, corn syrup, instant coffee powder, cocoa, caramel color, salt, potassium sorbate, citric acid, xanthan gum, polyglycerol esters of fatty acids, artificial flavor)
  • Ghirardelli Chocolate Drizzle (sugar, water, fructose, cocoa, natural flavor, unsweetened chocolate, potassium sorbate, salt, soy lecithin)
  • Whipped Topping (grade A cream, sucrose, corn syrup, nonfat milk solids, monoglycerides, natural and artificial flavors, salt, nitrous oxide gas)


Because most of the ingredients aren't natural or even wholesome, don't expect much in terms of nutritional value.

While this popular shake has a very low caffeine content, it has a very high sugar and calorie content.

A 16 fl oz cup of Arby’s Jamocha Shake contains 810 calories, 23 grams of fat, 119 grams of sugar, and 132 grams of carbohydrates.


The majority of people who have ordered this bev agree that it’s absolutely delicious.

Although you should be slightly concerned with how much sugar it contains, it’s a great cheat-day item if you want a tasty treat.

How To Make Arby's Jamocha Shake At Home

There are tons of copycat recipes for making Arby’s Jamocha Shake at home.

I can’t say that I’ve tried them all, but after testing several recipes, I found out what worked best for easily creating a delicious Jamocha Shake from home.

All you need is 4 ingredients:

  • Vanilla Ice Cream
  • Coffee
  • Chocolate Syrup
  • Whole Milk

In terms of equipment, you’ll need some type of blender. I have a Vitamix at home, which works wonders, but any blender will do. Simply add all of the ingredients together, blend, and enjoy!

Feel free to use natural ice cream for a natural vanilla flavor, or even non-dairy ice cream and a non-dairy milk alternative if you're sticking to a vegan diet.[3]

You have a few options for adding the coffee flavors. You can use brewed coffee, instant coffee, dark roasted coffee, or even espresso for an extra kick of caffeine.

I topped my Jamocha Shake with whipped cream and delicious chocolate syrup. And if you’re anything like me and hate runny shakes, add some ice to thicken it up.

Just have fun with your homemade concoction, and don’t be afraid to experiment to make it your own!
