20 Worst Restaurant Milkshakes—Ranked!

You're going to want to avoid these popular frozen treats at all costs.

Milkshakes appear to be an innocuous treat—one that's reserved for special occasions and celebrations. But when you think about what a milkshake is, you might realize just how absurdly indulgent they are: You take a pint or so of ice cream, add some milk to it—maybe some candy—and blend it all together so you can sip it through a straw. Not so innocent now, huh?

And it seems like restaurant milkshakes have taken a turn for the worst, as these frosty treats can easily pack over an entire day's worth of calories, fat, and sugar. Because some monster shakes out there feature scary amounts of the sweet stuff, so we're here to help you make a smarter choice when treating yourself.

That's why we ranked the most popular restaurant shakes from bad to the worst of the worst, based on the calories and sugar content. Avoid these at all costs if you're watching your sugar intake, or reserve them for a time when you hit the drive-thru with a friend.

From the Least Worst to the Absolute Worst


Wendy's Large Chocolate Frosty

Per shake: 590 calories, 15 g fat (10 g saturated fat, 0.5 g trans fat), 260 mg sodium, 99 g carbs (0 g fiber, 81 g sugar), 17 g protein

"When it comes to dessert, portion size can make all the difference," explains Megan Usher, RD, CDN. "For one-third of the calories, fat, and sugar, the junior size Frosty would make for a more appropriate treat. "Wendy's skews on the lower end of the shake spectrum, especially when it comes to saturated fat. However, 81 grams of sugar in their Frosty, as they call it, is still quite an unhealthy helping of the sweetener.

Chick-fil-A Cookies & Cream Milkshake

Per shake: 630 calories, 25 g fat (15 g saturated fat, 1 g trans fat), 410 mg sodium, 90 g carbs (0 g fiber, 76 g sugar), 13 g protein

Adding on a milkshake to enjoy along with the rest of your meal from Chick-fil-A seems harmless, but the cookies & cream flavor has more calories than the Spicy Deluxe Sandwich.


Burger King Chocolate Oreo Shake

Per shake: 684 calories, 17 g fat (13 g saturated fat, 0.5 g trans fat), 680 mg sodium, 117.6 g carbs (1.7 g fiber, 92.5 g sugar), 13.1 g protein

At Burger King, the chocolate Oreo shake has more calories than BK's Original Chicken Sandwich. Let that sink in. And that's not even factoring in the over 90 grams of sugar. Keep in mind The American Heart Association recommends women have no more than 100 calories (or about 6 teaspoons) per day of added sugars and for men, it's 150 calories or about 9 teaspoons daily.


Checkers Banana Milkshake

Per large shake (32 oz): 700 calories, 20 g fat (14 g saturated fat, 0 g trans fat), 390 mg sodium, 117 g carbs (3 g fiber, 95 g sugar), 14 g protein

Think going with a fruit-based option is better? Well, not so fast. See a Checkers' banana milkshake may be slightly lower in calories than other shakes offered at the fast-food chain, the largest size still packs 95 grams of sugar. That's more sugar than you'll get in nine Original Glazed Krispy Kreme donuts. So nope, it's not so innocent after all.


Carl's Jr. Hand-Scooped Oreo Cookie Shake

Per shake: 710 calories, 39 g fat (25 g saturated fat, 1.5 g trans fat), 340 mg sodium, 79 g carbs (1 g fiber, 53 g sugar), 13 g protein

As you're already aware, milkshakes can be a truly dangerous option, and when you add Oreo cookies to the mix, that just means things are only going to get worse. And that's exactly what happens at Carl's Jr. If you're looking for more help figuring out foods are the best and worst options out there, here is your ultimate restaurant and supermarket survival guide!


Hardee's Hand-Scooped Ice Cream Vanilla Shake

Per shake: 700 calories, 35 g fat (24 g saturated fat, 1.5 g trans fat), 240 mg sodium, 86 g carbs (0 g fiber, 65 g sugar), 12 g protein

Hardee's prides itself on the fact that each of their shakes is hand-scooped and made with real ice cream. It's blended with milk and a choice of chocolate, strawberry, or vanilla peach syrup. But don't think the plan ole vanilla flavor is the innocent one—it boasts 10 more calories than the other two flavors.


IHOP Oreo Cookie Milkshake

Per shake: 760 calories, 40 g fat (23 g saturated fat, 0.5 g trans fat), 340 mg sodium, 89 g carbs (1 g fiber, 65 g sugar), 13 g protein

At IHOP, the Oreo Cookie milkshake is packing more than 700 calories and 65 grams of sugar. That's a ton of the sweet stuff when it's no secret plenty of their breakfast options are already loaded with sugar!


Five Guys Bacon Milkshake with Whipped Cream

Per regular size: 770 calories, 40.5 g fat (25 g saturated fat, 1 g trans fat), 620 mg sodium, 85 g carbs (0 g fiber, 83 g sugar), 17 g protein

Five Guys is known for its scrumptious burgers and, yes, the extremely tasty shakes. If you're feeling creative, you can even mix and match a variety of flavor combinations, and you could end up sipping a Bacon milkshake. But don't think just because there is bacon that somehow makes it a better option. There's still 83 grams of sugar and 620 grams of sodium. That's a salty and sweet combination simply damaging to your health.

McDonald's Large Chocolate Shake

Per large shake: 830 calories, 21 g fat (13 g saturated fat, 1 g trans fat), 410 mg sodium, 139 g carbs (1 g fiber, 110 g sugars), 19 g protein

When McDonald's says that 'you deserve a break today,' they are right. Give your body a break from this fat-ladened chocolate beverage that has 830 calories and 13 grams of saturated fat. You can ask for your shake without whipped cream, which will reduce the total number of calories by 60 to 770 and bring down saturated fats to 11 grams and sugars to 106 grams. Hey, it's a start. The worse news, however, is that McDonald's uses one gram of trans-fat in their shakes, which raise your bad (LDL) cholesterol levels and lower good (HDL) cholesterol levels, increases your risk of developing heart disease, stroke, and type 2 diabetes.


Steak 'n Shake Reese's Peanut Butter Cup Regular Shake

Per shake: 840 calories, 43 g fat (18 g saturated fat, 0 g trans fat), 470 mg sodium, 98 g carbs (4 g fiber, 82 g sugar), 27 g protein

There are plenty of health benefits that come with eating peanut butter, but at Steak 'n Shake, all of that gets tossed out the window when it comes to its Reese's Peanut Butter Cup shake. Here, chunks of Reese's Peanut Butter Cups are blended into the homemade milkshake, making for a creamy dessert.


Shake Shack Cookies & Cream Shake

Per shake: 850 calories, 44 g fat (24 g saturated fat), 580 mg sodium, 98 g carbs (0 g fiber, 86 g sugar), 19 g protein

The burger joint is often known more for its rich and creamy shakes than its patties, but you might want to have a filling, less fattening meal instead of a dessert here. If you do decide to indulge in their one-size only shakes just know it will cost you more calories than most items on the menu! The cookies and cream shake is the perfect example, as it has the most calories, fat, and sugar.


BurgerFi Vanilla Shake

Per shake: 880 calories, 37 g fat (24 g saturated fat, 0 g trans fat), 240 mg sodium, 125 g carbs (0 g fiber, 109 g sugar), 12 g protein

It's obvious that BurgerFi is a place to get a good patty, but you should probably leave it at that and push yourself away from the table without dessert. Why? The vanilla shake comes with 24 grams of saturated fat and 109 grams of sugar. Yikes.


Friendly's Large Chocolate Fribble

Per shake: 988 calories, 32 g fat (21 g saturated fat, 0 g trans fat), 341 mg sodium, 149 g carbs (3 g fiber, 115 g sugar), 19 g protein

The large Hunka Chunka Fribble at Friendly's takes the idea of enjoying a sweet treat to the extreme. Here, peanut butter fudge ice cream is topped with hot fudge and a peanut butter topping. It's decadent and has 122 grams of sugar. No thanks!

Per shake: 990 calories, 39 g fat (25 g saturated fat, 1 g trans fat), 680 mg sodium, 145 g carbs (1 g fiber, 113 g sugar), 19 g protein

Their motto is 'we don't make it till you order it,' so leave off the shake when you place your order at Jack in the Box. This Oreo Cookie Shake with whipped topping and cherry is more than 1,000 calories, packs a hefty 39 grams of saturated fat, 1 gram of trans fat, and more 100 grams of sugar. There is nothing redeeming here!


Arby's Large Jamocha Shake

Per shake: 1,060 calories, 31 g fat (20 g saturated fat, 0.5 g trans fat), 650 mg sodium, 172 g carbs (1 g fiber, 147 g sugar), 24 g protein

At Arby's, chocolate and coffee come together for the famous Jamocha Shake. Yes, it's a magical combination, but it's best if you just take a few sips and leave the shake alone. Coming in at more than 1,000 calories and packing nearly 150 grams of sugar, this shake is nothing but trouble.


Denny's Cake Batter Shake

Per shake: 1,090 calories, 52 g fat (37 g saturated fat, 0 g trans fat), 890 mg sodium, 147 g carbs (0 g fiber, 122 g sugar), 13 g protein

Typically if you're dining at Denny's, it's for some breakfast, but there are plenty of other menu options for the rest of the day, and that includes over-the-top sweet treats like their milkshakes. The worst offender is the cake batter shake, as it has more than 1,000 calories and contains 122 grams of sugar.


Red Robin Chocolate Malt

Per Moster-size shake: 1,100 calories, 38 g fat (24 g saturated fat, 1.5 g trans fat), 390 mg sodium, 173 g carbs (1 g fiber, 156 g sugar), 20 g protein

At a towering 1,100 calories, 156 grams of sugar, and 1.5 grams of trans fat you would do yourself a service to forget about the ice cream chain's 1,700 flavors. In particular, "trans fats are linked with an increased risk of heart disease because of their negative effects on cholesterol levels," says Usher.

Johnny Rockets skyrockets you to the top of the calorie, saturated fat, and sugar mountain with this shake that is made up of a strawberry and Oreo combination and a malt powder from Johnny Rockets. Just say no!

Per large shake: 1,250 calories, 72 g fat (26 g saturated fat, 1.5 g trans fat), 830 mg sodium, 119 g carbs (4 g fiber, 89 g of sugar), 30 g protein

The home of the Blizzard seems to boast one of the more caloric shakes on the planet! The large peanut butter shake tops the calorie charts with a massive 1,250 calories and a whopping 89 grams of sugar. Not to mention, "this shake contains almost 40% of the recommended daily total sodium intake," Usher tells us. "When paired with other processed foods throughout the day, sodium can add up quickly. Consuming more than 2,300 mg per day increases the risk of high blood pressure, and subsequently, heart disease."

If you find yourself at Dairy Queen on a hot day, you may want to choose a mini-Blizzard instead, which will satisfy your craving for a refreshing shake with only a portion of the calories and fat content.

Per large shake: 1,720 calories, 106 g fat (48 g saturated fat, 2 g trans fat), 1,130 mg sodium, 168 g carbs (5 g fiber, 107 g sugar), 30 g protein

If your motto is 'go big or go home,' this shake is definitely one that fits the mold. "For the average person, this shake contains half of your daily sodium allowance, and enough calories for the whole day, fat for two days, and saturated fat for three days," Usher explains. This is Sonic's most indulgent shake on the menu and let's face it—it's hard to stop at half a shake! Resist the temptation and, instead, just don't order it.
