The 15 Best & Worst Frozen Fast-Food Desserts, According to a Dietitian

If you frequent fast-food restaurants, you've probably tried one of the many popular frozen desserts to finish your meal. While there's nothing wrong with occasionally treating yourself to something sweet, you may want to know which frozen desserts are better health-wise and which ones experts consider the unhealthiest fast-food desserts.

When evaluating the health impact of a fast-food dessert, there are a few factors you should consider:

• Calories: First, look at the dessert's overall calorie content. While calorie needs can vary greatly from person to person, choosing a dessert with a lower calorie count is often a good choice.
• Saturated fat: You'll also want to consider saturated fat content. Many frozen desserts are high in saturated fat and far exceed the daily limit of 13 grams recommended by the American Heart Association.
• Added sugars: Finally, pay attention to how much sugar the dessert contains. While it's true that any dessert will contain sugar, some fast-food desserts have upwards of three times the daily limit of 50 grams recommended by the Dietary Guidelines for Americans.

We've compiled a list of the 15 best and worst fast-food frozen desserts based on calories, saturated fat, and sugar content so you can make the best choice for your goals the next time you're at the drive-thru.

7 Healthiest Frozen Fast-Food Desserts

Best: McDonald's Vanilla Ice Cream Cone

"If you're looking for a simple dessert without a ridiculous amount of calories at McDonald's, consider the simple Vanilla Ice Cream Cone," says Michelle Rauch, MSc, RDN for The Actors Fund. At 200 calories, the vanilla cone won't break the calorie bank as you would with a McFlurry or Shake. Rauch adds that, at just 5 grams of fat, it's a lower-fat option than other menu items. Plus, you get 180 milligrams of calcium, 15% of the recommended daily value, which is important for bone health.

Best: Wendy's Jr. Classic Chocolate Frosty

If you're craving something chocolatey, look no further than the junior-sized Classic Chocolate Frosty from Wendy's. At less than 200 calories, it's a sweet treat that's not a calorie overload. Plus, it contains just 3.5 grams of saturated fat, making it a better choice for heart health than some of their other dessert options. While it contains 26 grams of sugar, some is naturally occurring sugar from lactose. It's important to note that the daily sugar recommendations refer to added sugar intake. That means naturally-occurring sugars like lactose don't count towards the limit. Stick to the junior size, as the calorie, saturated fat, and sugar content increase significantly with the larger sizes.

Best: Chick-fil-A Icedream Cup

While this frozen dairy dessert can't technically be called ice cream because it doesn't contain enough milk fat, it is a treat you can indulge in without sabotaging your health goals, says Kelsey Sackmann, MS, RD, owner of Kelsey P. RD. A cup of Chick-fil-A's Icedream will set you back 140 calories, and at 24 grams of sugar, it has significantly less sugar than most ice cream treats. Plus, at just 2.5 grams of saturated fat, it's a better choice for heart health than the chain's milkshakes.

Best: Baskin Robbins Blossom's Berry Twirl (One Scoop)

While many of the desserts on the Baskin Robbins menu are an overload of calories, saturated fat, and sugar, the individual scoops of ice cream are great options for those watching their portions.

Those concerned about their heart health can also enjoy this dessert, which clocks in at less than half the recommended daily intake of saturated fat.
