Keto powdered sugar is a homemade low carb version of traditional powdered sugar! All you need is a food processor and a high speed blender and you are set! 

Ever since making my own low carb powdered sugar, I’ve been using it in pumpkin cheesecake, brownie cookies, and in my favorite puppy chow

You may have noticed more and more supermarkets and grocery stores are slowly stocking more keto baking products. We’ve got keto syrups, keto chocolate chips, but keto sweeteners are quite difficult to come by.

As someone who would order keto confectioner’s sugar online, I realized I could easily make my own with granulated sweeteners!

Granululated keto sweeteners are easily accessible, like erythritol, monk fruit, and xylitol. All it takes to make your own powdered version is to simply blend it up or grind it until fluffy!

What is keto powdered sugar? 

Keto powdered sugar is a low carb version of generic powdered sugar. It is made without cornstarch, and is completely sugar-free, calorie free, and contains ZERO carbs (The carbs in normal powdered sugar is 25 grams per two tablespoons!). 

Depending on where in the world you are located, it can also be known as confectioner’s sugar or icing sugar

This low carb alternative is fantastic to use in ANY recipe that calls for powdered sugar. It has the exact same taste and texture of traditional powdered sugar. You can use it for frostings, cheesecakes, sprinkled over desserts, and more. The possibilities are endless! 

How do you make powdered sugar

Making your own sugar free powdered sugar is so simple. You’ll start by adding your sweetener of choice into a high speed blender or food processor. Next, you’ll blend it for 30 seconds or so, until it becomes fluffy. 

Use immediately, or store straight away, to use later. 


What kind of sweetener is best? 

  • Erythritol– This is my preferred sugar substitute to make into powdered sugar. It is what current keto powdered sugars on the market use. I find the taste to be most pleasant, and also mixes the best.
  • Monk Fruit Sweetener– This is similar to erythritol. It wasn’t as fluffy as I would have liked but still had a pleasant taste.
  • Xylitol– I generally don’t use xylitol in my recipes, but tried this as I’d seen a powdered sugar brand use it. It blended well, but had quite a bitter aftertaste. 

Do you need cornstarch to make powdered sugar? 

Traditional powdered sugar often contains cornstarch, to keep the powdered sugar from clumping together. As it’s not keto, I didn’t include it. However, after testing several batches, I found no difference in the texture or the mixability of my homemade powdered sugar. 

Storage Tips

You must always store the sugar in a sealable container or jar, kept out of direct sunlight. 

Do not freeze the powdered sugar, as it will seep moisture in and spoil. 

TIP: For the best result, I recommend preparing keto powdered sugar prior to using it in a recipe. It will not clump up, and it will be easier to mix as it is.

    1. This Puppy chow is for humans . It’s just a name of like checks mixed with a confectionary sugar . It’s not made for dogs . I know it gets confusing why they have names of a sweet for humans that’s called puppy chow . Like I said it’s just a name for sugar coated checks mix

  1. This article mentions how this can be used in dog treats. Please don’t be stupid and use this in dog treats. This has got to be one of the dumbest things I’ve ever seen on the internet.

    1. Jenna, this does not mention dog treats at all. Puppy chow is a food for HUMANS.

      (as clearly linked in the post too).

      Enjoy this recipe and the puppy chow recipe too

  2. Hi! I’m wondering if you’ve come across any additional alternative ingredients for keto sweeteners? Monk fruit is great but expensive, and I’m not able to eat sugar alcohols. I saw something called allulose which I need to research and try, but it seems expensive too. Stevia is good but tricky, since it’s so often blended with things that make me very sick!

    Thanks for this blog, I appreciate all these keto ideas!

  3. There’s another non-sugar-alcohol called Bochasweet. It’s an extract from a special kind of pumpkin. The main drawback I’ve seen about it is the price it’s very expensive. I haven’t tried it yet myself, just found out about it a couple of days ago. It could be the answer you’re looking for.I don’t know if it has any unpleasant gastric side effects or not.

        Hi Arman, I have since tried Bochasweet, and to me, it tastes exactly like sugar.

        I haven’t made powdered sugar out of any of the keto sweeteners yet, I’ve been using allulose for powdered sugar instead. It’s not quite a powder, but it’s pretty close, and dissolves easily.

  4. Does the keto powdered sugar have any after taste? Swerve has this strange feeling in my mouth…kind of minty but very unpleasant feeling in my mouth.

    1. Lorraine, Swerve is erythritol with monk fruit extract added. The funny taste is the monk fruit. It boosts the sweetness level, but I don’t like the monk fruit taste, either.

      I bought some pure monk fruit extract powder, and mix with erythritol to make it sweeter, but I use less than they do in Swerve. I don’t notice it in recipes, but for coffee I went back to using plain erythritol or allulose.

  5. Arman –
    It did reference dogs. Did you read the entire article?

    “ Ever since making my own low carb powdered sugar, I’ve been using it in pumpkin cheesecake, brownie cookies, and in my favorite puppy chow. “

  6. Hi Arman. It’s obviously a cultural and language problem. To most North Americans “Puppy Chow” is 1. A brand of dog food or 2. Slang for dog food! It is also a recipe as you say but there could still be confusion!

  7. I laughed at the 1st confused comment about the Puppy chow. But then more people commented on it… I was amazed. Yes. Puppy chow IS a name of a dog food, but it’s also (what I thought) was a well known snack recipe for humans. I enjoy all your recipes Arman!! Keep up the great work!! Now, I’ll have to try your puppy chow! lol. Woof!

    Hi Arman
    I just want to say that you are amazing, and so creative! I really enjoy your recipes. I’m not much of a cook ( my son is a general manager of a restaurant and he’s the best cook in the valley, so I really enjoy eating with him and his family.
    Your recipes look delish, so easy, and healthy that I’m going to have to break down and make them! They are very clearly written too!
    Thank you for sharing them with us!

    I’m so surprised by how many people thought “puppy chow” was actually dog food! 🤣 My sister use to make this tasty treat around the holidays. We’d munch on it while we watched old Christmas movies. Really glad there’s a keto recipe for this dessert!! Haven’t had it since I went keto.

  10. I have made the powdered sweetener for a while. I use my coffee grinder to make it. I don’t drink coffee, so my coffee grinder is used for making powdered sweetener, grinding flax and chia seed, making nut flours or butters.

  11. Arman, thanks so much for creating such amazing recipes.
    Lol, I too was in disbelief at the number of readers who commented on the “puppy chow”
    –one of my fave snacks since college,and I’m now 60+ just now using monk fruit and erythritol. Thanks for the wonderful site 🌹
