Six people, and what each one is actually for. No follower counts, no ranking, because neither of those tells you whether the person can explain why your cookies came out dry.
A roundup like this usually turns into a pile of accounts with audience sizes attached. That is a measure of reach, not of whether someone knows what sugar does structurally in a bake. So the list below is sorted by job. If you want our own starting point on picking a sweetener before you follow anybody, the sweetener guide covers that, and none of these six wrote it.
Two things before the names. I have not cooked every recipe on these sites, so this is a recommendation to read them, not a guarantee about any individual recipe. And every site sizes its servings differently, which is the one number that changes everything else on a nutrition line, so run the serving-size check on anyone new, including us.
For understanding what sugar was holding up: Katarina Cermelj
The Loopy Whisk is written by Katarina Cermelj, who has a PhD in inorganic chemistry from Oxford and started the site in 2016 after cutting gluten and dairy for health reasons. Her books are Baked to Perfection and The Elements of Baking.
She is the best writer I know of on why a substitution fails. Not "use this instead of that", but what the original ingredient was physically doing and what has to take over that job. Read her on binding, on hydration, on why an egg-free cake collapses, and the same reasoning transfers straight onto sugar even though she is not writing about sugar.
Where she stops being useful for us: she bakes with sugar. Her recipes are built for gluten, dairy and egg constraints, not carbohydrate ones. Take the mechanism, not the sweetener.
For low-carb baking that behaves: Carolyn Ketchum
All Day I Dream About Food has been running since 2010. Ketchum started watching her carbohydrate intake after gestational diabetes and went on to write The Ultimate Guide to Keto Baking, which is the single most practical book I have found on getting structure out of a bake with no flour and no sugar in it.
She is good on the things that go wrong quietly. How a sweetener behaves as a bake cools, why almond flour and coconut flour are not interchangeable at any ratio, when a recipe needs a binder. If you have ever pulled something out of the oven that looked right and turned to sand an hour later, she has written about it.
Where to be careful: keto baking is high fat by design, so calories often land higher than the carbohydrate line suggests. Read her fat numbers, not only her net carbs.
For sugar-free specifically: Katrin Nürnberger
Sugar Free Londoner started in 2016 and is one of the few sites where sugar is the actual subject rather than a side effect of a low-carb diet. Nürnberger was a freelance journalist before this, which shows in how clearly the posts are written.
Her recipe notes are worth more than her recipes. She tends to tell you which sweetener she used and what changes if you swap it, which is the information almost every sugar-free recipe on the internet leaves out. That question is the whole ballgame, and it is why we wrote our own erythritol explainer rather than pretending sweeteners are interchangeable.
Where to be careful: the site leans low-carb, so almond and coconut flour turn up constantly. If those are not in your cupboard, a lot of it will not be usable as written.
For substitutions explained line by line: Amy Atherton
Amy's Healthy Baking has been going since 2010 and carries a large sugar-free and low-sugar section. Atherton has a chemistry degree from UC Davis and wrote Healthier Chocolate Treats.
What she does that nobody else does at that length: she explains every single swap in the recipe body, including the ones that seem too small to matter. Why the yogurt is nonfat here and full fat there. Why a quarter teaspoon of baking soda changed. If you learn better by reading someone's reasoning than by reading a list, start with her.
Where to be careful: some recipes are built around specific branded stevia products, and a different brand at the same volume will not taste the same. Check what she used before you buy anything.
For flour, when gluten is also out: Nicole Hunn
Gluten Free on a Shoestring has run since 2009, and Hunn has written several cookbooks including Gluten-Free on a Shoestring Bakes Bread, plus her own multipurpose gluten-free flour blend.
Gluten-free flour blends are the part of this that most people get wrong, and getting it wrong is expensive. She is specific about which blend works in which application and why a cup-for-cup blend fails in a bread and works in a brownie. The cost angle is real too; a lot of this category assumes you will cheerfully buy four different flours.
Where to be careful: this is not a sugar-free site and it does not claim to be. If you need both constraints at once, take her flour work and someone else's sweetener work.
For the diabetes context around the dessert: Christel Oerum
Diabetes Strong was founded in 2015 by Christel Oerum, who has lived with type 1 diabetes since 1997 and spent more than a decade working in the diabetes industry before starting the site. There are hundreds of recipes on it, and dessert is a small slice of them.
She is on this list for a different reason than the others. Most dessert writing about diabetes is written by people who do not have it, and the tone gives it away instantly. Hers is written from inside the constraint, and the practical framing around meals, timing and what actually gets eaten in a normal week is more useful than another list of low-sugar recipes.
Where to be careful: she is a person managing a condition and writing about it, not your care team. Nothing on her site or on ours is medical advice, and your targets come from your doctor.
How to judge the next one yourself
You will find people I have not. Four questions sort them quickly.
Does the recipe say what the batch makes, in pieces or grams, and not just "serves 8"? A serving count with no size attached is the number that gets manipulated, and it is manipulated more often than the calorie count is.
Does the nutrition line print fat as well as calories? Sugar comes out of a dessert and something fills the space, and that something is usually fat. A single-number nutrition line has already chosen which number flatters it. Our own method for this is published for the same reason.
Does the writer name the specific sweetener and say what happens if you swap it? Erythritol, allulose and a monk fruit blend behave differently in the same bowl. Anyone writing "sugar substitute" without qualification has not tested more than one.
Does anything on the site admit to failing? A recipe archive with no failures in it either has not been tested much or has been tidied. The notes at the bottom of a recipe are where you find out whether someone actually made the thing twice.
Follow four people you trust rather than forty you scroll past. Then go make something and see whether the reasoning held up in your own oven.
