How do You Satisfy a Sweet Tooth on Keto?
There are many ways to satisfy a sweet tooth on keto. You can choose to make so many yummy keto desserts including this delicious chocolate frosty recipe made with just a few ingredients.
Tips to Make the Best Keto Frosty Recipe
Before you begin, here are a few tips you can use when making the recipe:
- For the best results, make sure you’re using a good sugar-free peanut butter. I usually go with my homemade keto peanut butter, but I get that not everyone wants to make their own. If you’re looking for a great store-bought option, I highly recommend picking up Justin’s Sugar-Free Peanut Butter on Amazon—it’s creamy, clean, and makes keto life so much easier.
This is my go-to creamy peanut butter for keto smoothies, snacks, and sauces! It’s super smooth, no-stir, and made with clean ingredients!
- Use chilled heavy cream for this recipe as chilled heavy cream from the fridge is best for whipping. If your heavy cream is at room temperature you may get a liquid frosty which you do not want. You should also chill your mixing bowl before whipping the cream.
- In order to avoid issues when serving, you can transfer the whipped frosty to a zip-lock bag and freeze it for 30-40 minutes. Then cut the end of the zip lock bag and pipe out the chocolate frosty into serving bowls or your mason jars.
Ingredients to Make Chocolate Frosty
Only a few ingredients are needed to make this low carb frosty recipe. They are:
- 1 cup of heavy cream, chilled
- 2 Tablespoons Sugar Free Peanut Butter (I recommend this creamy natural peanut butter that’s made with just peanuts and salt.)
- 1 Tablespoon Unsweetened Cocoa powder (this Dutch-process cocoa powder makes your frosty taste rich and decadent.)
- 1 Tablespoon Keto Sweetener (try this amazing keto sugar substitute.)
- 1 Teaspoon Vanilla Extract, optional
Tools to Make this Recipe
- Mason jars – These are perfect for serving this keto frosty. You can use a 12 or 16 oz mason jar to mix the ingredients (with a good shake or with an immersion blender.) But, the recipe makes 2 small servings of frosty (1/2 cup each) so you need smaller mason jars like these 5oz mason jars for serving.
These cute little mason jars are my go-to for storing everything from snacks, to desserts to my homemade nut butters. The airtight lids keep everything fresh and they look s slick and cute!
- Mixing bowls -You need these to measure out your ingredients and to mix the frosty.
- Hand mixer – If you’re making the frosty in a large mixing bowl (like I did) then a good hand mixer is a great tool to use to get all the ingredients properly mixed. Using a powerful hand mixer like this one will help you achieve that perfect thick, frosty texture.
- Measuring cups and spoons – You need accurate measurements for the ingredients so everything tastes perfect! These are the measuring cups and spoons I always use and recommend to everyone!
- Immersion blender (optional) – I did not use an immersion blender at the time of making this recipe for the blog. However, I’ve since gotten one and I can tell you it is hands down the best way to make a good keto frosty right inside of a mason jar! If you need a good immersion blender, this is a great one I recommend on Amazon.
- Blender (optional) – If you don’t want to shake to mix, use a hand mixer or and immersion blender, then you can simply add all the ingredients to a high-powdered blender like this one for that smooth, thick frosty texture.
How to Make Keto Chocolate Frosty Dessert
Gather all of your ingredients and use accurate measuring cups and spoons or food scale to measure out each ingredient.
You’ll need 1 cup of heavy cream, 2 tablespoons of sugar free peanut butter, 1 tablespoon of unsweetened cocoa powder, 1 tablespoon of keto friendly sweetener and 1 teaspoon of vanilla extract.
Next, add all of the ingredients into a large bowl and beat with a handheld electric mixer (this is the one I use from Amazon) or a whisk, until the mixture is smooth and whipped.
Then cover and pop this in a freezer for 40 minutes or until barely frozen.
Spoon the low carb chocolate frosty into your favorite glasses or these cute 5 oz mason jars and serve.
This is literally one of the easiest keto desserts you’ll ever try!
Keto Frosty Ice Cream Recipe
Is this a keto frosty ice cream recipe?
Many people think that a keto frosty is in fact a type of ice cream. In reality, a frosty isn’t an ice cream. In fact, it is a frozen dessert that is a mix between an ice cream and a milkshake. It isn’t as liquid as a milkshake, but also not as solid as ice cream. It’s typically eaten with a spoon and this yummy keto frosty dessert is no different! You’ll really enjoy this recipe if you’re looking for a quick and easy keto dessert that you can enjoy regularly.

What sweeteners can be used in this frosty recipe?
I used this Lakanto sweetener to make this frosty recipe, but feel free to use your favorite brand of keto friendly sweetener or even stevia!
How many carbs are found in each keto frosty?

Can I make this keto frosty in a mason jar?
Yes, you can make this recipe right in a mason jar! Just add all the ingredients and shake it up really well for a few minutes. It won’t get quite as smooth as using a blender or even a hand mixer, but if that’s what you’ve got, it works in a pinch.
That said, If you want to make a frosty with the best texture directly inside of a mason jar, I really recommend using an immersion blender—as it will give you that ultra-smooth, creamy texture. If you’re not ready to splurge, there’s a super affordable immersion blender I love over on Amazon.
This 5-in-1 immersion blender is a total game changer in the kitchen. Whether you need it for blending soups, whipping cream, or making keto smoothies, this handheld powerhouse does it all—and fast!

How to Store

Keep in mind that if you plan to enjoy this as a frosty, you should not freeze it as ice crystals will form and once thawed the frosty may just separate. If you freeze it and try to whip it again, it will not turn out as it was before. So, just pipe this keto chocolate frosty dessert into mason jars and enjoy.
Otherwise, you can also make frosty bites in a silicone ice cube tray, freeze them, and toss a few into your bulletproof coffee.
I use these every time I need perfectly sized ice cubes for iced coffee, smoothies, or even frozen fat bombs. They’re super easy to use, the lids prevent spills, and the cubes pop right out without twisting or banging.
Recipe Variations
Besides this chocolate flavored frosty, you can also make keto vanilla frosty, or keto strawberry frosty as well. Here’s how to make them.
Keto vanilla frosty: To make this version you will need heavy cream, unsweetened almond milk, lakanto sweetener, and vanilla extract.
Keto strawberry frosty: To make this variation, you will need fresh or frozen strawberries, heavy cream, keto sweetener, and a blender to blend everything together!
