Sugar-Free Cinnamon Roll Casserole
After years of testing low-carb breakfast bakes, I realized that traditional cinnamon rolls often turn tough when you remove the sugar. The real breakthrough happened in my kitchen when I swapped heavy dough for a lighter, custard-soaked base using almond flour and warm spices. Adding a touch of extra butter and letting the mixture rest for a few extra minutes before baking completely solved the dry texture issue, creating a rich, tender dish that rivals any traditional bakery classic.

Key Ingredients Breakdown
Almond Flour
Almond flour forms the core structure of our low-carb cinnamon roll dough. It provides healthy fats, a tender crumb, and a light nuttiness that mimics traditional pastry dough. If you have a nut allergy, sunflower seed flour works as a direct 1:1 substitute, though it may give the bake a slightly darker tint.
Coconut Flour
A small amount of coconut flour helps absorb excess moisture from the liquid ingredients without making the casserole dense. It gives the dough structure so it holds up well when baked in the custard. Do not replace coconut flour with more almond flour directly, as coconut flour absorbs significantly more liquid.
Granulated Erythritol or Monk Fruit
This sweetener provides the necessary bulk and sweetness for the cinnamon filling and dough without impacting blood sugar levels. Granulated sweetener blends melt evenly into the butter to form a rich cinnamon layer. You can use allulose if you prefer a softer texture and zero cooling effect.
Eggs
Eggs act as the primary binding agent and create a custard-like texture as the casserole bakes. They lift the dough pieces and give the casserole its fluffy structure. For best results, use room-temperature eggs so they mix smoothly into the batter.
Heavy Whipping Cream
Heavy cream creates a moist, rich custard that coats every piece of dough. It keeps the bake soft and prevents it from drying out in the oven. Unsweetened almond milk or coconut milk can be used for a lighter option, though the final texture will be less rich.
Cream Cheese
Cream cheese serves as the base for the signature glaze that gets drizzled on top of the warm casserole. It adds a slight tang that balances the sweet cinnamon flavor. Ensure it is fully softened at room temperature before beating to prevent lumps.

Pro Tips
- Use Room Temperature Dairy: Cold cream cheese or eggs can cause melted butter to solidify, leading to an uneven batter texture.
- Let It Rest Before Baking: Allow the assembled casserole to sit for 5 to 10 minutes before placing it in the oven so the flours absorb the liquid evenly.
- Cover If Browning Too Fast: If the top browns before the center is fully set, tent a sheet of aluminum foil loosely over the baking dish for the last 10 minutes.
- Glaze While Warm: Apply the cream cheese glaze while the casserole is still warm so it melts slightly into the crevices.
Storage & Reheating
Storage Guidelines:
- Refrigerator: Store leftover casserole in an airtight container in the fridge for up to 4 days.
- Freezer: Slice the baked casserole into individual portions, wrap each slice tightly in plastic wrap, and freeze in a zip-top bag for up to 2 months. Thaw overnight in the refrigerator before reheating.
Reheating Guidelines:
- Microwave: Place a single slice on a microwave-safe plate and heat on high power for 20 to 30 seconds until warm throughout.
- Oven: Cover the dish loosely with aluminum foil and reheat in a 300°F (150°C) oven for 10 to 12 minutes until warmed through.

Ingredients
- For the Dough Base:
​2 cups fine blanched almond flour
​1/4 cup coconut flour
​1/3 cup granulated monk fruit sweetener (or erythritol)
​2 teaspoons baking powder
​1/2 teaspoon salt
​4 large eggs, room temperature
​1/2 cup heavy whipping cream
​1/4 cup unsalted butter, melted
​1 teaspoon vanilla extract
- For the Cinnamon Swirl:
​1/3 cup unsalted butter, softened
​1/2 cup granulated monk fruit sweetener
​1 tablespoon ground cinnamon
- For the Cream Cheese Glaze:
​3 ounces cream cheese, softened
​2 tablespoons unsalted butter, softened
​1/3 cup powdered sweetener (such as powdered erythritol or confectioner’s monk fruit)
​2 tablespoons heavy whipping cream
​1/2 teaspoon vanilla extract
Directions
- Prep the Oven and Pan:​ Preheat your oven to 350°F (175°C). Lightly grease an 8×8-inch baking dish with butter or non-stick cooking spray and set it aside.
- Mix the Dry Ingredients: ​In a large mixing bowl, whisk together the blanched almond flour, coconut flour, granulated sweetener, baking powder, and salt until completely combined and free of lumps.
- Combine the Wet Ingredients: ​In a separate bowl, whisk the eggs, heavy whipping cream, melted butter, and vanilla extract together until smooth and uniform.
- ​Form the Dough Base: Pour the wet mixture into the dry ingredients. Stir with a spatula until a thick dough forms. Drop spoonfuls of the dough into the prepared baking dish, creating an even, rustic layer of bite-sized dough pieces across the bottom.
- Prepare and Add the Cinnamon Swirl:​ In a small bowl, mix the softened butter, granulated sweetener, and ground cinnamon together until a smooth paste forms. Dollop the cinnamon mixture generously over the dough pieces in the baking dish. Use a butter knife to gently swirl the cinnamon layer into the dough.
Notes
- Measuring Almond Flour: Always spoon almond flour into your measuring cup and level it off with a straight edge. Packing it down can result in a dense casserole.
- Sweetener Selection: Powdered sweetener is essential for the glaze. Using granulated sweetener in the glaze will result in a gritty texture.
- Equipment Needed: You will need an 8×8-inch ceramic or glass baking dish, two large mixing bowls, a hand mixer for the glaze, and a spatula.
- Troubleshooting Texture: If the center remains soft while the edges are browning, move the baking dish to a lower oven rack and bake for an additional 5 minutes.

Frequently Asked Questions
Can I make this sugar-free casserole the night before?
Yes. You can fully assemble the casserole in the baking dish, cover it tightly with plastic wrap, and store it in the refrigerator overnight. In the morning, remove the cover and let it sit at room temperature for 15 minutes while your oven preheats, then bake as directed.
Why is my cream cheese glaze lumpy?
Lumpy glaze occurs when the cream cheese or butter is too cold when mixed. Make sure both ingredients are thoroughly softened at room temperature. If it is already lumpy, microwave the glaze for 5 to 10 seconds and beat it again until smooth.
