Ingredients for Low-Carb Keto Cinnamon Buns

Here’s everything you need to pull these together. Quick note before you shop: make sure you grab finely ground almond flour, not coarse almond meal. The texture is completely different and it really does matter here.

• 1 1/2 cups finely ground almond flour
• 1 cup shredded mozzarella cheese
• 2 tbsp softened cream cheese
• 1 large egg
• 1/2 tsp baking powder
• 1 tbsp powdered sugar-free sweetener (for the dough)
• 2 tbsp melted unsalted butter
• 2 tbsp powdered sugar-free sweetener (for the filling)
• 1 tsp ground cinnamon

Ingredient Notes and Substitutions

The mozzarella and cream cheese are what make this a fathead dough. When you melt them together, they create a stretchy, pliable base that holds everything together. It sounds a little wild, but it works beautifully every single time.

Finely ground almond flour gives you that soft, tender crumb. Coarse almond meal makes the dough grainy and dense, so please don’t swap them.

For the sweetener, any powdered erythritol or monk fruit blend works great. Just make sure it’s powdered, not granulated, so it dissolves properly. Coconut flour is not a 1:1 substitute here, it absorbs way more liquid and will throw off the whole dough. Dairy-free cream cheese works if you need it.

Want a glaze on top? Mix 2 tbsp cream cheese, 1 tbsp powdered sweetener, and 1 to 2 tsp heavy cream until smooth. It’s so good drizzled warm.

Equipment You Will Need

Nothing fancy here, I promise. You probably already have everything in your kitchen right now:

• Microwave-safe bowl
• Baking sheet
• Parchment paper
• Rolling pin
• Sharp knife or unflavored dental floss for slicing
• Small mixing bowl

How to Make Low-Carb Keto Cinnamon Buns Step by Step

Okay, let’s do this. The whole process moves fast, so read through these steps once before you start. That little bit of prep makes everything so much smoother.

1. Preheat your oven to 375 degrees F and line your baking sheet with parchment paper. Set it aside so it’s ready to go.
2. Add the shredded mozzarella and cream cheese to a microwave-safe bowl. Microwave for 60 to 90 seconds, stopping halfway to give it a good stir. You want it fully melted and smooth.
3. Add the almond flour, egg, baking powder, and 1 tbsp sweetener straight into that warm cheese mixture. Mix everything together until a soft dough forms. Work quickly here. The dough gets stiff as it cools, and you want it pliable.
4. Place the dough between two sheets of parchment paper and roll it out into a rectangle about 1/4 inch thick.
5. In a small bowl, stir together the melted butter, 2 tbsp sweetener, and cinnamon until combined.
6. Spread that cinnamon filling evenly all over the dough, right to the edges.
7. Starting from one long side, roll the dough up tightly into a log. Take your time and keep it snug.
8. Slice the log into 8 equal pieces. This is where dental floss is your best friend. Slide a piece of unflavored floss under the log, cross it over the top, and pull. Perfect clean cuts every time without squishing the rolls.
9. Place each piece cut-side up on your prepared baking sheet. Bake for 12 to 15 minutes until the edges are golden brown.
10. Let them cool for 5 minutes before you dig in. I know it’s hard to wait, but they firm up just enough and taste so much better.

Tips for Working with Fathead Dough

First things first: this dough is not like regular dough. Don’t panic if it feels weird or a little stringy at first. That’s totally normal. Here’s what I’ve learned after making these more times than I can count:

• Work fast while the dough is still warm. It’s much easier to shape and roll right after mixing.
• If it sticks to your hands, just wet your fingers slightly. That little bit of moisture makes a huge difference.
• If the dough becomes completely unmanageable, pop it in the fridge for 5 minutes. It firms up just enough to work with again.
• Always roll between two sheets of parchment paper. It stops sticking and gives you a much more even rectangle.
• Don’t overthink it. Fathead dough is forgiving once you get a feel for it, and by your second batch, you’ll be a total pro.

Low-Carb Keto Cinnamon Buns Variations

Once you’ve nailed the base recipe, it’s so fun to mix things up. Here are some of my favorite ways to switch these around:

• Drizzle that keto cream cheese glaze on top for an extra indulgent finish
• Mix chopped pecans or walnuts into the cinnamon filling for a little crunch
• Add a pinch of cardamom or nutmeg to the filling alongside the cinnamon
• Slice into 12 pieces instead of 8 for cute little mini buns, perfect for kids
• Swap the cinnamon for a pumpkin spice blend in the fall

Serving Suggestions for Low-Carb Keto Cinnamon Buns

These buns are honestly perfect straight from the oven, but here are a few of my favorite ways to enjoy them:

• A hot cup of black coffee or bulletproof coffee on the side
• Scrambled eggs to round out a full keto breakfast
• Drizzled with that warm keto cream cheese glaze right before serving
• A cold glass of unsweetened almond milk for the kids

Warm is always the way to go. That gooey cinnamon center is at its absolute best when they’re fresh.

Storage and Reheating Instructions

Got leftovers? Lucky you. Pop them in an airtight container and store them in the fridge for up to 3 days. When you’re ready to eat, just microwave one for 20 to 30 seconds and it comes right back to life, soft and warm like it just came out of the oven.

Freezing is possible but honestly not my favorite option with these. The mozzarella dough can get a little rubbery after freezing and thawing. If you really need to freeze them, they’ll keep for up to 1 month. Reheat straight from frozen in the oven at 300 degrees F until warmed through.

Frequently Asked Questions About Low-Carb Keto Cinnamon Buns

Can I make Low-Carb Keto Cinnamon Buns ahead of time?
Yes, you can bake them the night before and store them in an airtight container in the fridge. Just reheat in the microwave for 20 to 30 seconds and they taste freshly baked.

What is the best sweetener to use in keto cinnamon rolls?
I love powdered erythritol or a powdered monk fruit blend for these sugar-free cinnamon rolls. Just make sure it’s powdered, not granulated, so it blends smoothly into both the dough and the filling.

Can I use coconut flour instead of almond flour in this recipe?
No, coconut flour is not a 1:1 swap for these almond flour cinnamon buns. It absorbs way more liquid and will completely change the dough texture.

Why did my fathead dough turn out sticky or hard to roll?
Sticky dough usually means it cooled down too fast. Wet your hands slightly or pop the dough in the microwave for 10 seconds to warm it back up.

Can I add a glaze to these almond flour cinnamon buns?
Absolutely, and I highly recommend it. Mix 2 tbsp cream cheese, 1 tbsp powdered sweetener, and 1 to 2 tsp heavy cream, then drizzle it over your warm keto cinnamon rolls right before serving.
