Powdered Sugar Substitute

Make my sugar free powdered sugar recipe once, and you’ll NEVER buy it again! All you need is one ingredient and a food processor or blender. Zero calories and zero net carbs.
You probably noticed more grocery stores are stocking sugar-free baking staples. There are plenty of sugar-free syrups and chocolate chips, but I’ve yet to find a suitable sugar-free powdered sugar.
Old me would order it online, but now that I know how easy it is to make at home, it’s a no-brainer to make my own powdered sugar substitute!

Why I love this recipe
- Easy to make. All you need is one ingredient, a blender, and less than a minute.
- It tastes like the real thing. So long as you use one of my preferred sweeteners, you won’t have to worry about a fake sugary aftertaste.
- Instantly make any recipe sugar-free. Once you have a pantry full of sugarless staples, you can quickly turn all your favorite baked goods sugar-free.
- Cheaper than store-bought. You’ll pay upwards of $5 more per bag for powdered sweetener versus granulated, and the only difference is the consistency.
Ingredients needed
- Granulated sweetener of choice. Of all the sweeteners I tried, allulose was my favorite for making powdered sugar. Most brands use it because it has a pleasant taste and texture. Monk fruit sweetener is a close second.
What sweetener is best?
Not all sugar-free sweeteners are created equal, and some are better for turning into powder. Here’s a quick breakdown:
- Allulose. My preferred sweetener as it has the best flavor and turns fluffy like regular powdered sugar.
- Erythritol. I don’t mind using erythritol, or erythritol blends, as a sugar alternative but I find it’s better to dissolve it in simple syrups for baking, instead of blending it into a fine powder.
- Monk fruit sweetener. Similar in rank to erythritol. It wasn’t as fluffy as I would have liked, but it tasted pleasant. Be careful because monk fruit sweetener is usually much sweeter than allulose or erythritol.
- Xylitol. I generally don’t use xylitol in my recipes, but I tried this as I’d seen a powdered sugar brand use it. It blended well but had quite a bitter aftertaste. It’s also VERY dangerous to dogs, so don’t share any treats if you use xylitol.
- Stevia. The only one I wasn’t a fan of, as I found it had a funky, slightly metallic aftertaste.

Frequently asked questions
Splenda can be used in place of powdered sugar, but it needs to be blended to a powder-like consistency.
Technically, they are different, as confectioners’ sugar typically has cornstarch added to prevent caking, whereas powdered sugar is made only with sugar.

Powdered Sugar Substitute
Ingredients
- 1/2 cup granulated sweetener of choice * See notes
Instructions
- In a high speed blender or food processor, blend your sweetener until fluffy.
- Transfer your powdered sugar to a sealable container.
In the keto frosting recipe, it says to use 3 CUPS sugar-free powdered sugar, but in your recipe for making your own sugar-free powdered sugar, it says to use 1/2 cup granulated sugar of choice. I really confused. I’m planning to make this on Thursday, 6/25. HELP!
Hi Mary- yes I hear you. You’ll need to just make 6 portions of this recipe. 6 half cup servings equals 3 cups.
Yummy
Glad you enjoyed the recipe!
Not sure what kind of Xylitol was being used, but Xylitol is the only thing I use because it does not have any weird after taste. Monk fruit and stevia taste like saccharin, erythritol has an odd minty quality that is not like regular mint, and allulose has a distorted sugar taste that I find unpleasant.
Xylitol has a bit of carb, but tastes more like sugar than anything else I have tried. It can be readily powdered, and is actually sold in powdered form.
Hi Shaunie, thanks so much for sharing your insight on this. With so many sweeteners out there these days, it’s great to know what people are enjoying!
Can I substitute stevia for the powdered sugar?
Hi Lynnette, I wouldn’t recommend stevia for this recipe. Powdered allulose, erythritol or monk fruit blends are the best options that will act as close to real powdered sugar in baking as possible.
Can you explain how you would dissolve the allulose in a simple syrup before blending into a fine powder?
Hi Tami, my comment refers to my preference of using some sweeteners in simple syrups, instead of blending them into a powder. I’ll fix this up for clarity! If you want to use allulose for this recipe, you certainly don’t need to dissolve it before blending.
Can you use Truvia to make the confectioner sugar, or the regular sugar?
Hi, I just found your recipes when I looked for “delicious wonderful absolute best keto low carb chocolate chip cookie recipes.” Then I found so many that I want to try, but you said something that has me confused.
You said that Allulose is your favorite for making powdered sugar. Then, under “What Sweetener is Best?,” you said “Allulose.” “I typically like using allulose as a sugar alternative, but I find it’s better to dissolve it in simple syrups than blend it into a fine powder.” You further stated that you prefer Erythritol (you left out one letter) sweetener as it has the best flavor and turns fluffy like regular powdered sugar.
You said “Powdered sweeteners should be kept in an airtight container away from direct sunlight. It’ll stay fresh for up to two weeks.” I have never had a problem with real sugar becoming unfresh; after all, it is used to preserve food. I have made keto powdered sugar (a blend of Erythritol, Allulose, and a bit of Stevia). I know that I have never felt the need to throw away regular powdered sugar even if had become somewhat caked because that is an easy fix. I have stored my homemade keto powdered sugar for several weeks so far, and I’ve not had any problems.
Thank you for reading this, and I welcome your comments. I do not like being wasteful, but I would not knowingly jeopardize the success of a recipe, either.
I’m glad I found your site.
Hi Cynthia- thanks for your detailed comment. I appreciate it.
I find allulose is best for this and have amended the notes in the recipe card to reflect it- With erythritol or monk fruit, it really comes down to the brand used- I don’t solely recommend either because there is a huge margin for error. When testing this recipe, I did find pre-blended allulose did get a little rancid after two weeks- I can’t really vouch for other sweeteners, but it got somehow a little moist at the base (and there was no moisture in the room or stored with it).
If you have a homemade keto powdered sugar that holds up and bakes well, don’t change it on my account- it sounds like the erythritol you are using is one of the better ones 🙂
I tried stevia and the crystals never broke down. I tried using it in frosting and it was grainy and like eating sand. Had to scrap the batch..
Hi Deb- I’m not surprised, seeing as in the post, I mention how stevia is the only one that I don’t recommend because it didn’t turn out well at all.
Arman, I’m sorry but you contradicted yourself. You said by far Allulose was your preferred sugar to make into a powered sugar but then you said you didn’t think it was good for a powdered sugar and it was better in simple syrups. I want to get this right so please, which is it? Thanks very much.
Was easy as directed but one issue- how do you get if from the food processor without it going everywhere?
Any tips/tricks would be great
Thank
Hi Jill, you could try stretching some plastic wrap over the top of the food processor bowl before securing the lid to keep everything contained a little more, and then carefully scoop it out to a jar for safe keeping. Hope this helps!
Loving your recipes. Being new to Keto cooking, it’s great to find shortcuts and make things a little cheaper! Thank you
You are so welcome, Edie, and that has always been one of my goals with developing low carb recipes- develop a bunch of staples so you can save a bunch of money, too. 🙂
You say you prefer allulose and then say you don’t prefer it. Which do you prefer for the powdered sugar texture?

Hi Chris, I’m not sure which section you’re referring to but for clarity, I find allulose to be the best for this recipe, providing the best powdered sugar texture.
Love making my own powdered sugar substitute when needed. But I do have a question. Can you make CRISP keto cookies using Allulose rather than erythritol? I just find the cooling effect overpowering in a simple cookie recipe like vanilla wafers. I have not had good luck before using Allulose MonkFruit blend.
Hi Bob, pure allulose is currently my preferred sugar substitute for baking as I find it mirrors the properties of real sugar more closely than other alternatives. I would give that a try!
How much do you have in the end if you use 1/2 cup allulose? Does the blending of it produce more volume?
Hi Elise, it actually ends up being about the same in volume. You get finer particles but they also become more aerated 🙂
Christmas Day 2024
Hi Arman,
Disaster struck today when I went to prepare whipped cream to top Mom’s Pumpkin Chiffon Pie, a family Thanksgiving and Christmas tradition that started before I was born.
No powdered sugar and all the stores closed!
I had granulated sugar, but knew using it as a substitute would result in a gritty texture.
Tradition was at stake!
Beginning when all I could do was lick the beaters, I learned how to make this pie at Mom’s side in the kitchen.
A quick check on the internet led me to you and your easy process for making powdered sugar. So simple, it should have been intuitive.
Using the organic granulated sugar I keep on hand for the hummingbirds, I rendered it into perfectly powdered sugar with the blender. I’ll be making my own from now on.
Yay!
Thank you, and Merry Christmas!
