Low-Carb Keto Cinnamon Buns – Soft, Sweet & Guilt-Free

Warm, gooey, and loaded with sweet cinnamon filling — nothing beats a freshly baked cinnamon bun. But traditional rolls are packed with sugar and carbs. These low-carb keto cinnamon buns deliver all the flavor and comfort of the original, with none of the guilt.

They’re soft, fluffy, and topped with a luscious cream cheese glaze. The secret? A combination of almond flour, mozzarella cheese, and cream cheese that forms a dough so tender and satisfying, you’d never guess it’s keto. Each bun is perfectly sweetened with a keto-friendly sugar substitute, giving you that indulgent taste without spiking your blood sugar.

Whether it’s a weekend breakfast, a cozy brunch, or an after-dinner treat, these keto cinnamon buns make any moment feel special — and they’re ready in under 30 minutes.

Why I Love This Recipe

I absolutely love these low-carb keto cinnamon buns because they’re the perfect balance between healthy and indulgent. They have the soft, chewy texture of a bakery-style cinnamon roll and that nostalgic cinnamon aroma that fills your kitchen — all while being gluten-free, sugar-free, and low in carbs.

The dough uses the famous “fathead” base made from almond flour, mozzarella cheese, and cream cheese. It might sound unusual, but it creates a soft, stretchy texture that mimics real bread dough beautifully. The cinnamon filling melts into the rolls as they bake, creating that gooey, sticky swirl that makes every bite irresistible.

Topped with a creamy glaze made from butter, cream cheese, and erythritol, these buns are a dream for anyone craving sweetness on a keto diet.

They’re proof that you don’t need to give up your favorite comfort foods — you just need to make them smarter.

Key Ingredients

To make these low-carb keto cinnamon buns, you’ll need simple keto-friendly ingredients you likely already have in your pantry.

• Almond Flour: Provides structure and keeps the dough gluten-free. Use fine almond flour for best results.
• Mozzarella Cheese: Helps create a chewy, bread-like texture in the dough.
• Cream Cheese: Adds moisture, flavor, and softness.
• Egg: Binds the dough together and helps it rise slightly.
• Erythritol or Monk Fruit Sweetener: A natural, zero-carb sweetener that mimics sugar perfectly.
• Cinnamon: The star spice that gives that warm, cozy flavor.
• Butter: Creates a rich filling and keeps the buns soft.
• Vanilla Extract: Adds sweetness and aroma to both the dough and glaze.
• Baking Powder: Gives a little lift to the dough.

Optional: Add a sprinkle of chopped pecans or a dash of nutmeg for extra flavor and crunch.

Step-by-Step

Follow these steps to make perfect low-carb keto cinnamon buns every time.

1. Make the Dough:
In a microwave-safe bowl, combine shredded mozzarella cheese and cream cheese. Microwave for about 45 seconds, stir, then microwave for another 30 seconds until melted and smooth.

2. Add Dry Ingredients:
In a separate bowl, mix almond flour and baking powder. Add the melted cheese mixture, egg, and a teaspoon of vanilla extract. Stir until a dough forms. Knead it gently until smooth and uniform.

3. Roll Out the Dough:
Place the dough between two sheets of parchment paper. Roll it into a rectangle about ¼ inch thick.

4. Make the Filling:
Melt butter and mix it with erythritol and cinnamon. Spread this mixture evenly over the rolled-out dough, leaving a small border around the edges.

5. Roll and Slice:
Using the parchment paper, carefully roll the dough into a log. Slice it into 8 equal rolls using a sharp knife or dental floss for clean cuts.

6. Bake:
Arrange the rolls in a greased baking dish. Bake at 375°F (190°C) for 15–18 minutes, or until golden brown and fragrant.

7. Make the Glaze:
Whisk together softened cream cheese, butter, erythritol, and a splash of vanilla extract. If needed, add a teaspoon of almond milk for a thinner consistency.

8. Glaze and Serve:
Spread the glaze over warm cinnamon buns and enjoy while gooey and soft.

You Must Try These Variations

These low-carb keto cinnamon buns are endlessly adaptable. Here are a few fun ways to change things up:

• Maple Cinnamon Buns: Add ½ teaspoon of maple extract to the glaze for a classic maple finish.
• Pecan Caramel Rolls: Sprinkle chopped pecans over the filling and drizzle with keto caramel sauce.
• Pumpkin Spice Rolls: Mix 2 tablespoons of pumpkin puree and pumpkin spice into the dough for a fall-inspired twist.
• Chocolate Swirl Buns: Add unsweetened cocoa powder to the filling for a rich chocolate-cinnamon combo.
• Sticky Buns: Add a thin layer of melted butter and erythritol to the bottom of the pan for a caramelized base.

Pro Tips

1. Use Fine Almond Flour: Coarse almond meal will make the dough gritty.
2. Work Quickly: Fathead dough becomes stiff as it cools, so roll and shape it while warm.
3. Don’t Overbake: Bake until just golden to keep the rolls soft and tender.
4. Glaze While Warm: The warmth helps the glaze melt beautifully into the rolls.
5. Store Smart: Keep leftovers in an airtight container in the fridge for up to 5 days, or freeze for up to a month.
