Make this Easy Keto Frosty in just one minute at home. Creamy, delicious, low-carb – step aside Wendy’s!

I have to admit, I have a weak spot for fast food! I’m not proud of it. It’s such unhealthy food, usually filled with cheap vegetable oils, high in carbs, and a variety of unpronounceable ingredients. Wendy’s Chocolate Frosty is no exception. It’s simply delicious, and simply doesn’t work for a healthy low-carb lifestyle.

Well, until now! This Frosty recipe is as creamy and chocolaty-good as the original, but keto-friendly. And the best part is, you can make it with just a handful of ingredients in only 1 minute!

What is a Frosty?

The Frosty is Wendy’s famous frozen dessert. It’s something between a milkshake and a soft-serve ice cream in consistency and has a light chocolate flavor. The founder of the fast-food chain Wendy’s wanted a dessert with a light chocolate flavor as he was concerned that full-on chocolate would be too overwhelming of a flavor to be served with burgers.

What are the ingredients of a chocolate Frosty?

As so often in fast food, the ingredients are little bit of a nightmare. This is what I found on Wendy’s website:

Milk, Sugar, Corn Syrup, Cream, Whey, Nonfat Dry Milk, Cocoa (Processed With Alkali), Guar Gum, Mono And Diglycerides, Cellulose Gum, Natural Vanilla Flavor, Carrageenan, Calcium Sulfate, Sodium Citrate, Dextrose, Vitamin A Palmitate.

Yep. Not only is it filled with sugar, it also contains corn syrup (in the U.S.), stabilizers, and emulsifiers. But as you can see, it also contains several ingredients that we can use to create our own, low-carb Frosty, like cream, milk, cocoa, and vanilla. So let’s get to it!

How to make a keto-friendly Frosty?

First of all, for this recipe you will need a blender, as we will crush up ice cubes to make a frozen milkshake! Our 3 main ingredients are heavy cream, cocoa powder, and erythritol. Erythritol is a low-carb sweetener that works great for this frozen dessert. To keep the chocolate flavor light (just like in the original), we will only use 2 tablespoons of cocoa powder. Now, let’s add some vanilla extract, after all the famous Frosty is a combination of both chocolate and vanilla. Lastly, I add a bit of salt to give the sweetness some depth. Blend all of this well, and you got your Frosty ready in just 1 minute!

Not only is this homemade Frosty just as thick and creamy as the original, it only has 3 grams of total carbs per cup. One recipe makes about 4 cups. So you can either divide into 4 small servings or 2 large servings. Perfect!

Tips for making a thick and creamy low-carb Frosty!

Blender. You need a somewhat strong blender. It doesn’t have have to be a super-expensive Ninja blender, but the motor needs to be strong enough to crush ice.

Ice. The more ice cubes you add, the thicker your Frosty will end up being. Somewhere between 2-2.5 cups of ice cubes seem to be working best for me. This results in a thick Frosty that can be enjoyed with a straw or a spoon. If you think your Frosty is too thin, simply add more ice to your blender.

Cocoa powder. The Classic Frosty uses alkalized (Dutch-process) cocoa powder, and that’s what I use for my homemade Frosty, too. It has a darker color and milder flavor that regular cocoa powder. However, you can also use regular cocoa powder, the result is very similar.

Serving. This recipe is enough for 4 small servings or 2 large servings. You can enjoy it as is, or even top it off with some whipped cream if desired. Serve right away, as the ice will melt and the Frosty will lose its thick texture. If one recipe makes too much for you, simply make half the recipe, so you won’t have any leftovers.

Variations. Do you like to experiment with different flavors? Make it chocolate-mint by simply adding a few drops of mint extract. Or try mocha: Freeze coffee in an ice cube tray and add some to your blender.

    EXCELLENT!!!! Thank you again! 🙂

    Small typo on the file. Where it reads “… Serve right away, as the ice will melt and the Frosty will use its thick texture.”

    Should read: “and the Frosty will LOOSE its thick texture.”

    Cheers!
