Zero Carb Milkshake Recipe

a glass with a milkshake topped with whipped cream, marshmallows and a red swirl straw

Finding a dessert under 1 gram net carb can be tough. Sugar-free sweeteners have zero carbs, but flour replacements like almond and coconut flour don’t. Even heavy cream has 0.3g carbs per tablespoon. I use only 3 tablespoons to keep this under 1 gram.

It’s still creamy and sweet with a toasted marshmallow flavor from flavoring extract drops.

Is Heavy Cream Allowed on the Carnivore Diet?

It depends! Some strict carnivore who only eat beef, salt and water will say no, but others who consume anything from an animal will be okay with it. And there are others who do allow a small amount of extras, like sweeteners, spices, plant oils – as long as the carbs are near zero. Since heavy cream has 0.3 g carbs per tablespoon, as long as you don’t consume too much, you will be fine. Three tablespoons of heavy whipping cream is enough to make this carnivore milkshake creamy without adding in too many carbohydrates.

Flavoring

I choose to make this zero carb dessert a toasted marshmallow flavor using flavoring extract from One on One Flavors. You can save 10% off your order with my code Ketofocus-10. You can use any flavor extract in this recipe. If you use the drops, add 1/2 to 1 dropperful of extract. If you use a regular flavor extract, like vanilla, add in 1/2 teaspoon. Experiment with different flavors. Try adding chocolate, almond and coconut to make an almond joy flavor. For graham cracker and toasted marshmallow to make a s’mores milkshake! They even have a banana extract for those missing banana smoothies!

Sweetener

Technically, sweeteners are not allowed on the carnivore diet; although, some do consume them in moderation. As you progress on a meat only diet, you will lose your sweet tooth and not really crave anything sweet. Some people adopt a blend of the carnivore and keto diets called a ketovore diet. These folks mostly eat carnivore (meat only) on the weekdays and then splurge with some keto foods on the weekends. They will consume sweets and plant based foods on the weekends, but still try to stay as low of carb as possible.

Frequently Asked Questions

Can I substitute the heavy cream for another ingredient?

Yes. Use unsweetened almond or coconut milk for lower fat, but it will change the texture - less creamy.

What can I use if I don’t have monkfruit sweetener?

Use erythritol or stevia. Adjust to taste since sweetness levels vary.

How can I make this milkshake dairy-free?

Replace with coconut cream or nut-based cream. Make sure it's unsweetened.

What’s the best way to store any leftover milkshake?

Best fresh. Leftovers keep in the fridge for a day - shake or blend again before drinking.

How many carbs does this milkshake have?

Under 1 gram with monkfruit and the ingredients listed.

    This was great for a quick treat after dinner. I used vanilla extract since I didn’t have flavor drops. It turned out creamy and refreshing. A nice keto option when you're short on time.
