Sometimes I just want one cinnamon roll. Not a pan of twelve, not a batch I have to freeze or give away. Just one, with a gooey center and cream cheese frosting melting over the top. At just 5.7g net carbs, this is the recipe I reach for on those mornings, and I've been making it long enough to know exactly where the dough likes to stick and how thin to roll it.

The dough comes together in a single bowl. Almond flour, egg white protein powder, xanthan gum, and sour cream give it a texture that's soft and pillowy without any gluten. The xanthan gum does the structural work, giving the dough a real stretch to it (almost like wheat dough, which surprised me the first time I made it). If you're out of egg white powder, a fresh egg white works. Skip the water and add a little extra almond flour until the dough lifts off parchment without tearing.

The filling is where I went heavier than most keto versions. I use a full half tablespoon of melted butter mixed with brown sugar-free sweetener and cinnamon, brushed edge to edge so every layer has that gooey, buttery center. Most recipes skimp on the filling and you end up with dry bread that happens to be spiral-shaped. Not this one.

I bake mine in a 4 oz ramekin at 325 degrees F. The sides hold the roll upright while it puffs, and you get a golden top in about 17-20 minutes depending on your oven and how thick you rolled the dough. Roll it to about 1/4 inch or thinner before adding the filling. Too thick and the center stays gummy no matter how long you leave it in. I figured that out after a reader messaged me about an underdone middle, and going thinner fixed everything. The ramekin also makes cleanup a one-dish situation, which matters when I'm making this for a quick breakfast.

You can also make this in an air fryer at the same 325 degrees F. Start checking at 8-9 minutes. The circulating heat crisps the top faster than a standard oven.

The cream cheese frosting goes on while the roll is still warm. Thick, cold, tangy, it melts just enough at the edges to pool into the cinnamon layers. I sometimes make a double batch of the frosting because I like it that thick.

If you're into making one-serving treats like this, I also make a single serve keto donut with a similar dough base. For more low carb breakfast ideas, my keto cream cheese danish and keto french toast are in my regular rotation. And if you want that same cinnamon hit, try my keto churro donut holes.

Ingredient Swaps I've Tested

I’ve tested several ingredient swaps to keep this low carb, and here’s what works.

  • Almond flour: Sunflower seed flour substitutes 1:1 for a nut-free version. Cashew flour works too (reader JustMe confirmed the same texture). I also use almond flour as the base for my almond flour pancakes, and the texture varies by brand, so if your dough is wetter than expected, add a teaspoon more.
  • Egg white protein powder: Use one fresh egg white, skip the water, and add extra almond flour. Unflavored collagen peptides also work since the xanthan gum handles most of the binding.
  • Sweeteners: Brown sugar-free sweetener in the filling gives the best depth. You can use your regular granulated sweetener for everything if you don’t want to buy both.
  • Butter: Coconut oil works for dairy-free.
  • Sour cream: Full-fat Greek yogurt is the best swap here. Readers Nicole and Sarah both reported the dough came out stretchier and easier to handle with yogurt.

If you like cinnamon baking, my keto apple fritters and gluten-free monkey bread use a similar flavor profile.

Storing and Freezing

This recipe makes one large roll that’s over 500 calories, so it works as a full meal. If I get full halfway through, I wrap the rest and store it in the refrigerator for up to 3 days. For reheating, I use the microwave for 10-15 seconds, the air fryer at 200 degrees F for 1 minute, or the oven at 300 degrees F for 2-3 minutes.

You can also freeze the baked roll (without frosting) for up to 2 months. I wrap it tightly in plastic wrap, then foil. Thaw overnight in the fridge and reheat in the oven before adding fresh frosting. I’ve been making keto baked goods long enough to know that frosting never freezes well on anything, so always add it fresh.

Frequently Asked Questions

Can I make this in the microwave or air fryer instead of the oven?

I've made this in the air fryer at 325 degrees F and it works. Start checking at 8-9 minutes since the circulating heat crisps the top faster than a standard oven. I haven't tested baking this in the microwave and wouldn't recommend it. The texture depends on dry heat to set the outside while the inside stays soft, and microwaves tend to make almond flour baked goods rubbery. A toaster oven at the same temperature is a better alternative if you don't want to heat a full oven.

Can I freeze this recipe and reheat it later?

I've frozen these and they reheat well. Wrap the baked roll (without frosting) tightly in plastic wrap, then foil, and freeze for up to 2 months. When I want one, I thaw it in the fridge overnight and reheat in the oven at 300 degrees F for 3-4 minutes. Add fresh frosting after reheating. The texture holds up better than I expected, though the edges lose a tiny bit of crispness.

What's the best sweetener for the cinnamon filling?

I use brown sugar-free sweetener (like Swerve Brown) in the filling because it has that molasses depth that cinnamon needs. Allulose gives you a softer, more caramelized result since it actually browns with heat, but it's only about 70% as sweet as sugar, so I use a little more than the recipe calls for. Straight erythritol works but can recrystallize as the roll cools, leaving a gritty texture in the filling. For the dough itself, any granulated keto sweetener is fine.

Why use a ramekin instead of baking on a sheet pan?

I bake mine in a 4 oz ramekin because the sides hold the roll upright while it puffs up. Without that support, the spiral tends to uncoil and flatten on a sheet pan. You still get a good result on parchment, but the roll spreads wider and thinner. If you want that tall, bakery-look shape with a pillowy center, the ramekin makes the difference.

Can I use coconut flour instead of almond flour?

I haven't done a full coconut flour swap for this recipe, but one of my readers (Mickey) added about half a teaspoon of coconut flour when the dough was too wet and it thickened up perfectly. Coconut flour absorbs roughly 3-4 times more liquid than almond flour, so if you're substituting entirely, start with about 2 tablespoons of coconut flour and add water a teaspoon at a time until the dough is tacky but lifts off parchment. Cashew flour is an easier 1:1 swap if you can't do almonds but can handle other tree nuts.

What can I substitute for egg white protein powder?

I recommend using one fresh egg white instead of the powder. Skip the water and add extra almond flour until the dough lifts cleanly off parchment paper. I've also had a reader test unflavored collagen peptides as a 1:1 swap and the roll held up fine. Collagen doesn't bind as tightly as egg white protein, but the xanthan gum handles most of the structural work in this recipe, so either substitute gets you there.

What does xanthan gum do in this recipe and can I skip it?

Xanthan gum gives this dough its stretch and hold. It's what makes the roll feel like the real thing instead of crumbly almond flour bread. I wouldn't skip it if you're using egg white powder. But if you swap in a fresh egg white for the powder, you can leave the xanthan gum out since the egg white provides enough binding on its own. Add extra almond flour to keep the dough from getting too sticky.

I was scared to try baking keto for the first time, but this came out SO soft! The middle stayed gooey too! Can I mix the dough the night before and bake it in the morning?

Thank you for doing a single serve version of this. Not having a whole pan sitting on the counter is honestly the reason I made it.

Eight and not one leftover, that’s the best kind of report. I’m so glad they worked for brunch, Wendy!

Already prepping to make this tonight and just realized I’m out of egg white protein powder. I’ve subbed whey in other keto baking and it usually messes with structure, but with only one tablespoon in a single-serve recipe I’m not sure it matters much. Would a 1:1 swap work, or do I need to adjust the water or sour cream?

Reply

Annie Lampella

Renee, whey at one tablespoon probably won’t tank it, but it pulls more moisture than egg white powder. I’d cut the water to half a tablespoon and see if the dough holds. Better sub I’ve actually tested is one fresh egg white: skip the water entirely, add a little extra almond flour until the dough lifts off parchment clean.

Reply

Danielle G.

Egg white protein powder, done.

Reply

Annie Lampella

Danielle, good. Egg white powder is what holds this dough together without the extra moisture adjustment. I’ve tried whey and it works but the dough gets sticky, you’d be adding almond flour to get it back to the right consistency. Powder you just measure and mix. The xanthan gum does the rest.

Spray the ramekin twice. Learned that the hard way.

Reply

Annie Lampella

Same. I spray twice and let it sit a couple minutes before running a knife around the edge. The sides want to hold on if you try to pop it too soon.

25 minutes each but the batch math works out on Sundays.

Batch Sunday works. Four ramekins staggered in the oven and you’ve got the week done in under two hours.

Oh smart, staggering them. I’ve been doing two at a time and it takes way longer than it needs to.

Loved this overall, the buttery cinnamon filling for one is exactly what I needed so I don’t end up with a full batch. Fair warning though, shaping the dough into a spiral was way stickier and fussier than I expected, mine kind of smeared into a lopsided blob before it hit the ramekin. Still tasted great and the cream cheese frosting covered a lot of sins. Just give yourself more time on that step than the recipe implies, especially your first time with almond flour.

Reply

Annie Lampella

Wet hands help, but mine always smears a little. Once it’s in the ramekin it doesn’t matter what it looked like getting there.

Was skeptical this would actually hold together as a roll. The xanthan gum does its job though. I pressed the dough flat on parchment, added the cinnamon butter, and it spiraled and baked like a real cinnamon roll, not a crumbly mess. The cream cheese frosting is the right amount, sweet but not overwhelming. Four stars because my bake time was closer to 22 minutes at 325, but I’m making this again tomorrow.

Reply

Annie Lampella

Your oven runs cool. Try 350 and start checking at 18. Making it again tomorrow beats four stars anyway.

Used Greek yogurt instead of sour cream because that’s all I had. Dough came out so soft I genuinely thought I did something wrong. I didn’t. Whatever that swap does is freaking wild.

Reply

Annie Lampella

Greek yogurt’s already listed as the swap right in the ingredients. You followed directions without knowing it. Less fat, more protein, it just hydrates the dough differently.

I’ve been strict keto for two years and cinnamon rolls were the thing I genuinely mourned (not exaggerating, I used to plan Sundays around them), and I’ve tried probably six different versions at this point, every single one letting me down in some specific way, too dense or gummy or the frosting tasted like it was trying to fool me. Made this last Saturday and something about how the xanthan gum works in the dough, it actually stretches, it actually pulls apart the way a real cinnamon roll does, and I wasn’t ready for that. Pulled it out of the ramekin and the smell hit me and I stood at my counter for a second before I ate it because I just needed to look at it. The cream cheese frosting ratio is exactly right, not too sweet, not too thick. I’ve made it three times already this week, once on a Thursday night for absolutely no reason except I wanted it.

Reply

Annie Lampella

The Thursday one is the real endorsement. No occasion, just wanted it.

My daughter walked in while it was cooling and I ended up splitting it with her. Immediately regretted that. Two ramekins next Sunday.

Annie Lampella

Two ramekins. One was never going to hold once she caught that smell cooling.

Started pre-mixing the dry ingredients into individual bags on Sundays, so weekday mornings are just wet ingredients and 25 minutes. Four bags lined up, no measuring required. The dough comes together fast with everything pre-measured, which I didn’t fully appreciate until I was eating a warm cinnamon roll before 7am on a Tuesday. The one thing I make fresh each morning is the cream cheese frosting (doesn’t hold past day one), but that’s barely 30 seconds. The ramekin size is the real reason this works as a meal-prep recipe. I’ve made other keto baked goods that technically scale down fine but leave you calculating, and this one doesn’t.

Reply

Annie Lampella

The Sunday bag system is smart. Four bags ready to go, just add wet ingredients – I wish I’d put that in the post. And yeah, frost it fresh. Even 12 hours in the fridge and it gets weirdly dense.

Been air frying everything lately and wondering if this works without the oven. The 325°F in a ramekin feels intentional, like the slow heat matters for texture somehow. Would the circulating air dry it out or mess with how the cinnamon-butter center sets? Really don’t want to ruin that part.

Reply

Annie Lampella

Air fryer at 325 works. Start checking at 8-9 minutes since the top crisps faster with the circulating heat than it would in a regular oven. The cinnamon center sets fine, keep the ramekin in.

My daughter kept asking for bites even after I told her it was the only one. She never touches anything I make on keto but she wouldn’t stop staring at that cream cheese frosting. Making her one next weekend.

The frosting-to-roll ratio on a single serve is way higher than a full batch. She noticed. Make her one and don’t mention the keto part until after.

Had zero faith almond flour could give me a real cinnamon roll center. Sunday morning test run and the gooey middle actually delivered. Four stars because my edges got a tiny bit dry, but I’m making this again next weekend.

Reply

Annie Lampella

The ramekin’s running hot at the sides before the center catches up. Throw some foil over it the last 4-5 minutes and the edges calm right down.

My daughter has loudly rejected every keto thing I’ve made for three years. Sunday she ate most of my single-serve cinnamon roll and didn’t say a word. Soft center, gooey cinnamon, right out of the ramekin. She had no idea it was almond flour. Wants one every weekend now.

Reply

Annie Lampella

Ha, three years of no and one Sunday morning. The almond flour just doesn’t have that gritty tell in this dough, it bakes out smooth.

Reply

Okay I was convinced there was no way this was going to taste like an actual cinnamon roll (I’ve tried too many keto baked things that came out weirdly gummy or just flat and sad) but something about the xanthan gum and that sour cream in the dough actually worked, like genuinely worked. The cinnamon-butter center got all melty and gooey and when I put the cream cheese frosting on while it was still warm I just stood at my counter and ate the whole thing right there. Getting back on track this spring and I really needed this.

Reply

Annie Lampella

The frosting on warm is non-negotiable. It melts into the spiral and you lose track of where the filling ends and the frosting starts. Counter eating is how I know a recipe worked.

Reply

Marcus

Rest the dough 2-3 minutes before shaping it. Xanthan gum needs time to activate, and what feels like a sticky mess becomes workable. Found this out the hard way on batch two rushing straight to parchment and it kept tearing. Now I mix, prep the filling, come back. Rolls right out.

Reply

Annie Lampella

Yep, same routine. Mix, butter the ramekin, come back. Two minutes and it rolls out clean.

Reply

Stephanie

I’ve been trying to get back into keto after a rough winter and this recipe looks like exactly the kind of thing that’ll keep me on track (I have a serious weakness for cinnamon rolls). The only thing stopping me is the xanthan gum, I can’t find it anywhere locally and ordering online just for one ingredient feels excessive. I’ve made keto baked goods before but have no idea what xanthan gum actually does or why it matters to the dough. Would leaving it out completely ruin the texture, or is there something more common I could use instead? Don’t want to just wing it on the first try.

Reply

Annie Lampella

Skip the xanthan gum and use a fresh egg white instead of the protein powder. It binds. No water either, the egg white has enough moisture. Add a little extra almond flour until the dough lifts off parchment without tearing.
