Keto Cinnamon Buns

The smell of cinnamon wafting through the house on a Sunday morning used to be something I missed terribly after starting keto. That changed when I finally cracked the code for low-carb cinnamon buns that actually taste like the real deal.

I made these for my skeptical sister who swore keto baked goods always tasted like cardboard. Watching her eyes widen at first bite made all the recipe testing worth it. She texted me the next day asking for the recipe.

Ingredients

• Almond flour: Creates the tender crumb structure and keeps these perfectly keto-friendly
• Coconut flour: Absorbs moisture and prevents the dough from becoming too dense
• Erythritol sweetener: Provides the classic cinnamon bun sweetness without spiking blood sugar
• Baking powder: Gives these buns their rise and fluffiness
• Salt: Balances the sweetness and enhances all the flavors
• Shredded mozzarella cheese: The secret ingredient that creates the stretchy, gluten-like dough texture
• Cream cheese: Adds richness to the dough and makes the most luscious icing
• Eggs: Bind everything together and contribute to the fluffy texture
• Ground cinnamon: The heart and soul of any cinnamon bun, use good quality here
• Unsalted butter: Creates that irresistible cinnamon sugar filling we all love
• Powdered erythritol: Dissolves beautifully into the icing for that smooth finish
• Vanilla extract: Rounds out the frosting with warm, comforting notes
• Unsweetened almond milk: Adjusts the icing consistency without adding carbs

Instructions

Prep your baking station:

Preheat oven to 350°F and line an 8-inch round pan with parchment paper for easy removal later

Melt the cheese base:

Combine shredded mozzarella and cream cheese in a microwave-safe bowl, heating in 30-second intervals while stirring until completely smooth

Whisk the dry ingredients:

In a large bowl, mix almond flour, coconut flour, sweetener, baking powder, and salt until well combined

Form the dough:

Add the melted cheese mixture and eggs to the dry ingredients, stirring with a spatula until a sticky dough forms

Roll it out:

Place the dough between two sheets of parchment paper and roll into a rectangle about 1/4 inch thick

Make the cinnamon filling:

Mix erythritol, cinnamon, and melted butter, then spread evenly over the rolled dough

Roll and slice:

Using the parchment paper to guide you, roll the dough into a log from the long side and cut into 8 equal pieces

Bake to golden perfection:

Arrange buns cut-side up in your prepared pan and bake for 22 to 25 minutes until golden and set

Whip up the icing:

Beat cream cheese, butter, powdered erythritol, and vanilla until smooth, adding almond milk as needed

Finish and serve:

Let buns cool for 10 minutes, then spread the icing over warm buns and enjoy immediately

These became a Christmas morning tradition after my first attempt turned out surprisingly well. Now my family actually looks forward to keto breakfast instead of mourning their usual cinnamon rolls.

Making Ahead

You can prepare the dough and filling the night before, refrigerate separately, then assemble and bake fresh in the morning. The buns reheat beautifully at 350°F for about 5 minutes if you need to make them ahead.

Customization Ideas

Chopped pecans or walnuts folded into the filling add wonderful crunch and healthy fats. For extra protein, you can even sprinkle a little vanilla protein powder into the dough mixture.

Storage Tips

Store any leftover buns in an airtight container in the refrigerator for up to 3 days. They actually develop even more flavor overnight as the cinnamon permeates the dough.

• Reheat individual buns in the microwave for 20 to 30 seconds
• The toaster oven works great to recrisp the edges
• Freeze uniced buns for up to a month and add fresh icing later
