I make this single serve keto cinnamon roll when the craving hits but I don't want a whole batch staring at me. One soft, fluffy roll with a gooey cinnamon-butter center and cream cheese frosting, ready in about 25 minutes. Just 5.7g net carbs.
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.

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 the microwave for this recipe 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 sweeter so I use about 3/4 the amount. 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.
Okay so I used Greek yogurt instead of sour cream because that's what I had, and the dough came out SO much more stretchy than I expected. No gluten, somehow elastic. I was nervous the whole time because I've never really worked with almond flour dough and it kept sticking to my hands, but wetting my fingers fixed it and it pressed into the ramekin no problem. The cinnamon center was genuinely gooey when I cut into it, like the butter soaked all the way through. This is becoming my Sunday morning thing.
Swapped the sour cream for full-fat Greek yogurt. Dough was way easier to handle, still puffed up fine. The tang actually played off the cream cheese frosting in a way I didn't expect.
Made this Saturday morning, barely got a bite. My 9-year-old walked in right as I was pulling it out of the ramekin, smelled the cinnamon, and just stood there waiting. She has zero interest in anything I label 'keto' and I didn't label this one. The xanthan gum actually gives the dough this real pull to it, almost like gluten, which I wasn't expecting from a single serving. Setting up two ramekins next weekend so I don't lose mine again.
That xanthan gum pull is exactly what I was going for. It's what makes this feel like a real cinnamon roll instead of just an almond flour thing. Two ramekins is the smart move.
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.
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.
My mom made these on Sunday mornings from a tube of Pillsbury. I stopped letting myself think about that when I went keto. The cream cheese frosting on this one finished the thought.
Pillsbury on Sunday mornings is tough to beat. The frosting on this one is thick, cold, tangy. I think that's what does it.
Cold and tangy is exactly it. That's what did it for me.
Made this on a snow day when I was out of egg white protein powder. Used unflavored collagen peptides instead (same amount) and was a little nervous. Roll came out soft, cinnamon center still gooey. Collagen works if you're ever in the same spot.
Good to know. Collagen doesn't have the binding power of egg white protein, but with the xanthan gum doing most of the structural work in this one, I can see why it held up. Filing that away for snow days.
Fifth time making this. I keep it in my rotation for when I need something sweet fast but don't want to drag out a full batch of anything. Takes me closer to 22 minutes now that I know the timing.
Fifth time is when you really dial it in. I'm usually closer to 22 now too, depends how thick you roll the dough.
Made this as a late night snack when the cinnamon roll craving hit. 25 minutes start to finish and I didn't have to share it with anyone.
Ha, the no-sharing part is key. I make this one when I want dessert but don't want to bake a whole batch of something.
This is my go-to when I want something sweet after dinner but don't need a whole batch. 5.7 carbs for a real cinnamon roll is hard to beat.
That's exactly why I love this one too. Sometimes you just want cinnamon roll satisfaction without the temptation of 11 more sitting on the counter.
Took me a couple tries to get the dough thin enough for a good roll. First time it was too thick and didn't cook through in 17 minutes. Second time I went thinner and it was perfect. Worth the learning curve.
Drew good call on rolling it thinner. You want it about 1/4 inch or even a little less so the center cooks through. I should add that to the recipe notes.
I make this every Sunday morning now. The cream cheese frosting while it's still warm is everything.
Sasha yes. The frosting on a warm cinnamon roll is non-negotiable. I make a double batch of the frosting sometimes because I like it that thick.
The cinnamon butter filling is the best part. It melts into the dough while baking and you get that gooey center without any sugar.
That's the part I keep coming back to honestly. The filling ratio is way higher than most cinnamon roll recipes so you get that gooey layer all the way through instead of just at the edges.
Took a couple extra minutes past 17 to get the top golden in my oven but worth the wait.
Yeah ovens run different. Mine's usually 19-20 for that golden top. The extra couple minutes is worth it.
Could you substitute whey powder for egg white?
I haven't tried whey powder in this recipe. Using one egg white is a better substitute for the egg white powder — just omit the water and add extra almond flour since the egg white has more moisture. You want the dough tacky but not sticky.
The dough was very wet. Instead of additional almond flour, I added about a ½ teaspoon coconut flour to thicken it. Also, from my baking experience, baked goods should reach an internal temperature of around 205-210ºF to be sure the inside is completely baked through leaving no gummy, undercooked dough. Baking this at 325ºF to an internal temperature of 205ºf, my cinnamon roll took almost 30 minutes to be done. Ate it while still warm and it was delicious.
Mickey the coconut flour trick is smart since it absorbs so much more liquid than almond flour. And the internal temp tip is really helpful. Almond flour brands vary a lot in how much moisture they absorb so cook times can really differ.
