    I used to love grabbing a chocolate frosty from Wendy's as a quick snack. But after ditching carbs, this was no longer an option.

    That's why I created my own keto frosty recipe. It's a quick and easy way to make the thick frozen low carb milkshake.

    You will not be disappointed with this treat! The consistency is similar to soft serve ice cream.

    Keto Frosty Ingredients

    There's only five simple ingredients needed to make a thick milkshake. You probably already have them in your kitchen.

    ingredients needed for the shake recipe

    I use heavy whipping cream and unsweetened almond milk as the creamy base. Vanilla extract, unsweetened cocoa powder, and a low-carb sweetener is used for the flavor.

    For dairy-free, you can easily substitute the cream with a non-dairy heavy cream alternative.

    Low-Carb Shake Recipe Steps

    It only takes about ten minutes of prep time to make the shake. But you'll need to allow about 2 to 3 hours of freezing time.

    recipe steps

    Just follow these simple steps:

    1. Whip heavy whipping cream to soft peaks.
    2. Add the rest of the ingredients and beat until stiffer peaks form.
    3. Freeze and stir every 20 minutes or so with a fork.
    4. Remove from freezer and enjoy once soft serve consistency is reached.

    That's all there is to making your own low-carb keto chocolate frosty!

    Keto Wendy's Frosty Variations

    Feel free to tweak the sweetener amount to suit your taste. I feel the shake has the perfect sweetness for me, but others may want it more or less sweet.

    Although I do own an ice cream maker, I chose not to use it for this recipe. However, you can churn the mixture in your machine as it will be much easier.

    If you want to make a vanilla Frosty instead, up the vanilla extract to ¼ to ½ teaspoon and omit the cocoa powder. You can also add in some vanilla bean.

    Other flavors are also possible by using keto-friendly syrups or flavor extracts!

    Frequently Asked Questions

    What is a Frosty?

    A Frosty is a frozen treat sold by the fast food chain Wendy's. It comes in chocolate or vanilla and is a cross between soft-serve ice cream and a milkshake.

    How many carbs in each frosty?

    A Wendy's Frosty junior size has about 33g of carbs. But my keto friendly version has less than 5g net carbs for a similar size serving.

    What's the best sweetener to use?

    My original recipe used Truvia. But about 2 tablespoons of a low-carb granulated sweetener like Lakanto Classic White works well too.

    Can the frosty be made in a blender?

    The recipe has been tested using a hand mixer, blender, and ice cream maker. Any of these provide a soft serve consistency after stirring and freezing.

    Is it essential to have stiff peaks before freezing?

    If you are unable to reach stiff peaks after adding the cocoa powder and sweetener, it's fine. Just make sure enough air has been incorporated before freezing.

    Storing Leftovers

    The recipe makes a single one cup serving so there shouldn't be any leftovers. But if you can't finish it, it can be place in the freezer for later.

    Freezing more than a few hours isn't recommended as ice crystals can form easily. The best soft-serve texture is achieved with the initial freezing so the keto frosty should be enjoyed immediately.

    If you do keep the mixture in the freezer for more than a couple hours, it will freeze very hard. Therefore, you'll want to let it sit out at room temperature to thaw out a bit before eating.

    Ingredients

    • 6 tablespoons heavy whipping cream
    • 5 tablespoons unsweetened almond milk
    • ⅛ teaspoon sugar-free vanilla extract
    • 2 tablespoons cocoa powder
    • 1 ½ teaspoons Truvia or 2 tablespoons equivalent sugar substitute

    Instructions

    • Start whipping cream with mixer until soft peaks form.
    • Slowly add remaining ingredients.
    • Continue beating until stiffer peaks form.
    • Put mixture in freezer.
    • After 20 minutes, remove from freezer and stir with fork to break up frozen areas around edges.
    • Keep checking mix every 20 minutes and stir until it’s cold enough and the right consistency.

    Notes

    If you have an ice cream maker, the mixture can be turned frozen much faster by churning in a machine.
    A blender can be used instead of a mixer if it's able to whip the cream to soft peaks.
    The unsweetened cocoa powder can be left out and more vanilla extract or vanilla bean added to make a vanilla frosty.

      Yummy! I make my own Matcha smoothie. Fill blender glass with ice 3/4 up. Add teaspoon matcha powder, sweetener to taste, and the tea is bitter so add enough. Fill with milk of your choice, I like almond. Add a heaping teaspoon of powder milk. Blend.

        You can but half and half doesn't whip up as well as heavy cream.

      Years ago, Wendy's Frosty actually had lots of chocolate in it. These days, it's hard to tell the Chocolate from the Vanilla by looking at it! Real chocolate is expensive for fast food drive-ins, so they barely put any in. I love homemade- you can put as much real chocolate or cocoa in your own shake! Yum!
