From shakes to a perfectly swirled soft serve, frozen fast food desserts tend to be friendly on the wallet—but the waistline? Not so much. While there are no illusions that frozen fast food desserts are healthy, they vary wildly when it comes to just how much of an indulgence they are. For example, a fresh banana shake from Sonic might seem harmless, but it isn’t actually healthy. At 57 grams of sugar, it has more of the white stuff than serving of Oreos.
Of course, if you want a treat without messing with your flat belly progress, there are some ways to help keep the calories and sugar in check. Choose the smallest option available—a mini or kid-size is often plenty, and will be half the fat as a large. Keeping toppings and mix-ins to a minimum will also help improve the nutritional profile of the treat, so skip the chocolate syrup, caramel, whipped cream, candied nuts, and cookie dough chunks. Keep in mind that the “healthier” options are also packed with artificial ingredients and additives like cellulose gum and carrageenan.

The Best Frozen Fast Food Desserts
Chick-Fil-A Icedream Cone
Like so many things at Chick-Fil-A, their creamy, low-cal “Icedream” has a bit of a cult following. The frozen dairy dessert can’t be called ice cream because it doesn’t have enough milk fat, which makes it a delicious boon for anyone watching their weight. A cone will only set you back 170 calories and has significantly less sugar than the other frozen treats on the list.
Wendy’s Vanilla Frosty
Wendy’s Frostys are known for being a relatively good choice when it comes to frozen fast food desserts. So if you want to get the biggest bang for your nutritional buck, order a junior size vanilla frosty (a chocolate one will only set you back a few calories so don’t feel guilty if you want to indulge your chocolate cravings or—even better—make it a swirl).
Steak ‘n Shake Root Beer Float
Craving something frothy and creamy? Grab a straw and a spoon to dig into the root beer float at Steak ‘n Shake. While the root beer and ice cream combo make this treat a sugar bomb, it’s much lower in fat and calories than many other options.
Dairy Queen Hot Fudge Sundae
DQ is best known for their Blizzards, but it actually has a host of other frozen dessert offerings (that’s kind of their thing). Their small hot fudge sundae won’t do too much damage at only 300 calories even with the decadent chocolate topping.
Burger King Hershey’s Sundae Pie
With a crunchy chocolate crust, a frozen “crème” filling, and a chocolate syrup topping, Burger King’s Hershey’s Sundae Pie is a brownie sundae in pie form. And as decadent as it sounds (and tastes!), it’s actually a pretty moderate option compared to other frozen dessert options.
McDonald’s McFlurry with Oreo Cookies
The classic McDonald’s McFlurry is high in calories, but with a little ordering info, you can cut some of the bad stuff (aka fat and sugar) while still enjoying a delicious indulgence. Oreo cookies are a less fatty mix-in than M&Ms, and ordering the snack size instead of the regular will further reduce calories, sugar, etc.
The Worst Frozen Fast Food Desserts
Sonic Fresh Banana Shake
If you’re looking for a healthy dessert option, a fresh banana shake may sound like a good bet. But don’t be fooled by the fact that there’s real fruit in here (though of course bananas have their health benefits). When something is called a shake instead of a smoothie you know it’s likely going to have ice cream in it, and despite how much fruit is in it, it doesn’t undo the other bad things in it. At 530 calories and 57 grams of sugar for a mini, this is a treat you definitely want to skip.
Five Guys Bacon Milkshake
With bacon and milkshake in the name, you already know what you’re getting yourself into. This over-the-top Five Guys option is not only packed with calories, saturated fat, and sugar but—because of the bacon—it’s also super high in sodium. The other flavors—banana, chocolate, cherry, and Oreo creme—aren’t much healthier either. So if you must indulge, we recommend enjoying only half or sharing.
Culver’s Banana Split
Known for their mouthwatering variety of ice creams, Culver’s is a popular chain in the Midwest. You may think that a banana split is a healthier option than, say, a milkshake, but this definitely proves that wrong. With a whopping 1,065 calories and 60 g of fat, this is definitely not a dessert that should be consumed solo.
Applebee’s Blue Ribbon Brownie
Drumroll, please. The worst frozen dessert is…the Blue Ribbon Brownie at Applebee’s. There are less decadent items on the dessert menu (the hot fudge sundae shooter has 410 calories, for example), but this hot fudge brownie sundae is a definite splurge. This is definitely one of those treats that is best for sharing with a group.
