These keto cinnamon rolls are soft, gooey, and swirled with buttery cinnamon filling under a tangy cream cheese frosting — at just 4 grams of net carbs per roll. Made with a sweet fathead dough, they’re ready in about 50 minutes. This guide covers the full recipe, the technique for rolling and slicing fathead dough without tears, exact macros, six variations, make-ahead overnight strategy, and fixes for dry or unraveled rolls.

A Cinnabon-style cinnamon roll packs 80+ g of carbs — the frosting alone is a sugar delivery system. But the experience of a cinnamon roll (warm, gooey, spicy-sweet, drowning in tangy frosting) doesn’t actually require wheat or sugar. Fathead dough, sweetened and enriched, rolls up beautifully around a butter-cinnamon filling; allulose in the filling melts into genuine goo; and cream cheese frosting needs barely any adaptation at all. This is a weekend baking project that pays off like nothing else in keto baking.

Why This Recipe Works: The Science

• Sweet fathead dough. The classic mozzarella-almond flour dough, enriched with sweetener, vanilla, and an extra egg yolk for tenderness. The cheese provides the stretch needed for rolling; the almond flour keeps it tender. It behaves remarkably like a sweet yeast dough when warm.
• Roll it warm, between parchment. Fathead dough is pliable when warm and brittle when cool. Rolling between two sheets of parchment to an even rectangle, then using the bottom parchment to lift and roll the log, prevents every common tearing disaster.
• Allulose in the filling = real goo. Erythritol recrystallizes as it cools, making fillings gritty; allulose stays molten and syrupy, creating the gooey cinnamon swirl that defines a great roll. Brown-style erythritol blends also work well here.
• Dental floss for slicing. A knife squishes the soft log; unflavored dental floss (or thread) slid under and crossed over cuts perfect clean rounds with zero compression. The oldest cinnamon-roll trick, and it matters doubly with soft fathead dough.
• Bake close together. Snug rolls in the pan push against each other as they bake, rising taller with soft, pillowy sides — exactly like classic cinnamon rolls.
• Frost warm, not hot. Frosting on piping-hot rolls melts into a puddle; on properly warm rolls it softens into a luscious glaze that sets into a tangy cap. Five minutes of cooling is the window.

Choosing Your Cinnamon (It Matters More Than You Think)

Not all cinnamon is equal, and in a recipe where it’s the headline flavor, the choice shows:

• Saigon (Vietnamese) cinnamon: the boldest, sweetest, most intense — high in cinnamaldehyde, the compound behind cinnamon’s punch. The best choice for cinnamon rolls where you want maximum impact.
• Ceylon (“true”) cinnamon: delicate, citrusy, complex — lovely in subtle applications, but it gets lost in a fathead dough. It is, however, much lower in coumarin, so heavy daily users sometimes prefer it.
• Cassia (standard supermarket): the middle ground most recipes assume. Perfectly good; just make sure your jar isn’t three years old — ground cinnamon loses potency within a year.
• Freshness test: rub a pinch between your fingers and smell. If the aroma is faint, replace the jar. Stale cinnamon is the silent killer of cinnamon rolls.

Ingredients for Keto Cinnamon Rolls

Makes 9 rolls (9-inch round pan or 8×8-inch square).

For the sweet fathead dough

• 1¾ cups (175 g) shredded low-moisture mozzarella — block, shredded fresh.
• 2 oz (55 g) cream cheese
• 1½ cups (150 g) blanched almond flour, finely ground
• ¼ cup (50 g) granular erythritol or monk fruit blend
• 1 tablespoon baking powder
• 1 teaspoon vanilla extract
• 1 large egg + 1 large egg yolk, room temperature — the extra yolk adds richness and tenderness.
• ¼ teaspoon fine sea salt

For the cinnamon filling

• ¼ cup (55 g) butter, very soft — spreadable, not melted. Melted butter leaks out during rolling.
• ⅓ cup (65 g) brown-style erythritol or allulose — brown-style gives the classic caramel note; allulose gives the gooiest melt.
• 2 tablespoons ground cinnamon — use a good, fresh cinnamon; it’s the star. Saigon cinnamon is particularly intense.
• Pinch of salt

For the cream cheese frosting

• 115 g (4 oz) cream cheese, softened
• 2 tablespoons butter, softened
• ⅓ cup (40 g) powdered erythritol or allulose — sifted to remove lumps.
• 1 teaspoon vanilla extract
• 1–2 tablespoons heavy cream — to reach spreadable consistency.
• Pinch of salt

How to Make Keto Cinnamon Rolls: Step by Step

1. Make the dough. Melt the mozzarella and cream cheese together (microwave 90 seconds, stir, 30–60 seconds more) until smooth. Stir in the almond flour, granular sweetener, baking powder, and salt, then the egg, yolk, and vanilla. Knead with oiled hands 2–3 minutes until smooth and pliable. If it stiffens, microwave 15–20 seconds.
2. Roll it out. Place the warm dough between two large sheets of parchment. Roll into a rectangle roughly 30×40 cm (12×16 inches), about 5 mm / ¼ inch thick. Peel off the top parchment. Patch any tears by pressing dough together — warm fathead is very forgiving. A rolling pin Check Price on Amazon → with thickness guides helps keep it even.
3. Fill. Spread the very soft butter evenly over the dough, leaving a 2 cm / ¾-inch border along one long edge (this seals the roll). Mix the brown sweetener, cinnamon, and salt; sprinkle evenly over the butter, right to the edges except the sealing border. Press gently so it adheres.
4. Roll the log. Starting from the long edge opposite the border, use the bottom parchment to lift and roll the dough into a tight log, peeling the parchment back as you go. Keep it snug — a loose roll unravels in the oven. Pinch the sealing border to close. If the dough resists, it’s cooled too much — warm it 15 seconds in the microwave (before filling next time).
5. Slice with floss. Slide a 30 cm piece of unflavored dental floss under the log, bring the ends up, cross them, and pull — a perfect round pops free with zero squishing. Cut 9 even rolls (about 4 cm / 1½ inches each). Wipe or re-cut floss between slices.
6. Pan and proof-warm. Butter a 9-inch round pan or 8×8-inch dish. Arrange the rolls cut-side up, snugly — they should touch. They won’t rise like yeast dough, but 10 minutes in a warm spot relaxes them into the pan.
7. Bake 20–25 minutes at 175°C / 350°F until golden brown and firm — the centers should look set, not doughy. The filling will bubble and caramelize around the edges. Don’t overbake; fathead dries out past golden.
8. Frost. Cool 5 minutes — warm, not hot. Beat the frosting ingredients until smooth and spreadable; spread generously over the warm rolls so it melts into every swirl. Serve immediately — warm, gooey, and absolutely irresistible.

Pro Tips

• Temperature discipline. Every step of fathead work is easier warm. If the dough fights you at any point — rolling, sealing, slicing — it’s too cool. Fifteen seconds in the microwave fixes everything.
• Don’t skimp on the cinnamon. Two full tablespoons sounds like a lot; it’s the correct amount. Keto doughs are mild, and the filling needs to be assertive to read as “cinnamon roll” rather than “sweet bread.”
• Brown sweetener matters. Brown-style erythritol (with a touch of molasses flavoring, no actual sugar) gives the filling its classic caramel depth. White sweetener works but tastes flatter.
• Tight roll, clean swirl. A snug log gives the Instagram spiral; a loose log gives cinnamon blobs. Roll firmly and evenly, using the parchment for leverage.
• Floss, not knife. This bears repeating: dental floss cuts fathead cleanly where knives compress it. Unflavored, unwaxed floss; thread works in a pinch.
• Serve warm. Like all fathead baking, these peak warm from the oven. Reheat leftovers 15 seconds in the microwave or 5 minutes in a 160°C / 325°F oven.

Variations to Try

• Orange rolls: add 1 tablespoon orange zest to the dough and replace the vanilla in the frosting with 1 teaspoon orange extract + 1 tablespoon orange juice. Bright and stunning.
• Sticky pecan: pour a sauce of ¼ cup melted butter + ⅓ cup brown allulose into the pan before adding the rolls; scatter pecans over. Flip the pan after baking for upside-down sticky buns.
• Chocolate: add 2 tablespoons cocoa to the filling and fold sugar-free chocolate chips into the dough. Frost with chocolate cream cheese frosting.
• Apple pie (keto-style): add ½ cup finely diced chayote squash sautéed in butter with cinnamon to the filling — chayote bakes into a shockingly apple-like texture at a fraction of the carbs.
• Savory pizza rolls: skip sweetener and vanilla in the dough; fill with marinara, mozzarella, and pepperoni. Same technique, dinner application.
• Mini rolls: roll the rectangle tighter and cut 12 smaller rolls; bake 18–20 minutes. Two-bite brunch party format at ~3 g net carbs each.

Storage, Freezing, and Overnight Method

Room temperature: frosted rolls keep 2 days covered (the frosting needs refrigeration in warm climates — when in doubt, refrigerate). Refrigerate: up to 5 days; reheat before serving. Freeze: freeze unfrosted baked rolls up to 3 months; thaw overnight, warm 10 minutes at 160°C / 325°F, then frost fresh — nearly indistinguishable from fresh-baked. Overnight method: assemble sliced rolls in the pan, cover tightly, refrigerate overnight; bake straight from the fridge adding 3–5 minutes. Wake up, bake, frost — the ultimate holiday morning strategy.

Frequently Asked Questions

How many net carbs are in keto cinnamon rolls?

About 4 grams of net carbs per roll (one of nine) with cream cheese frosting, using almond flour fathead dough and erythritol/allulose. A standard mall-style cinnamon roll has 80–90 g net carbs. The carbs here come from the almond flour, cream cheese, and cinnamon — all in modest quantities per roll.

Why is my fathead dough tearing when I roll it?

It’s too cool. Fathead dough is pliable when warm and brittle when cold — reheat 15–20 seconds in the microwave and try again. Also, roll between parchment (never directly on the counter), keep the thickness even, and patch tears by pressing warm dough together; it melds seamlessly.

Can I make cinnamon rolls without mozzarella?

Not with this technique — the melted mozzarella is what makes the dough rollable. For a dairy-sensitive alternative, try a psyllium-based sweet dough (almond flour + psyllium husk powder + whipped egg whites, as in keto dinner rolls, with added sweetener and vanilla). It won’t roll into a spiral as cleanly, but baked as sweet buns with cinnamon filling and frosting, it satisfies the craving.

How do I get the gooey center?

Three things: allulose (or brown-style sweetener) in the filling, which stays molten instead of recrystallizing; don’t overbake — pull when the centers look just set; and serve warm. The goo is at its peak in the first 20 minutes out of the oven, which is exactly when you should be eating them anyway.

Can I prepare cinnamon rolls the night before?

Yes — it’s the ideal holiday strategy. Assemble the sliced rolls in the buttered pan, cover tightly with plastic wrap, and refrigerate overnight. Bake straight from the fridge, adding 3–5 minutes. Make the frosting while they bake. Christmas morning cinnamon rolls with zero morning prep.

Why did my rolls unravel while baking?

The log was rolled too loosely or the sealing edge wasn’t pinched firmly. Roll snugly using the parchment for leverage, pinch the border seam closed, and place the rolls seam-side positioned so neighbors hold them shut. A snug pan (rolls touching) also braces them against each other.

Can I freeze keto cinnamon rolls?

Yes — freeze baked, unfrosted rolls up to 3 months (wrap individually). Thaw overnight in the fridge, warm 10 minutes at 160°C / 325°F, and frost fresh. The texture is nearly identical to fresh-baked. You can also freeze the frosting separately for up to a month; thaw and re-whip before using.
