Ingredients
Method
- Prep your pan and oven: Heat the oven to 350°F (175°C). Line a 9x5-inch loaf pan with parchment and lightly grease it so the bread lifts out cleanly.
- Mix dry ingredients: In a large bowl, whisk 2 cups almond flour, 2 tablespoons coconut flour, 2 teaspoons baking powder, 1 teaspoon cinnamon, and 1/4 teaspoon salt. Add a pinch of xanthan gum if using.
- Whisk wet ingredients: In another bowl, whisk 4 large eggs, 1/2 cup granular keto sweetener, 1/2 cup melted butter, 1/2 cup full-fat Greek yogurt, and 1 teaspoon vanilla. Make sure the butter is cooled so it doesn’t scramble the eggs.
- Combine: Pour the wet mixture into the dry. Stir until just combined. The batter will be thick but spreadable. Avoid overmixing to keep the crumb tender.
- Make the cinnamon swirl: In a small bowl, mix 2 tablespoons granular sweetener with 1 to 1.5 teaspoons cinnamon. This creates the ribbon of cinnamon throughout the loaf.
- Layer the batter: Spread half the batter in the pan. Sprinkle the cinnamon mixture evenly over it. Add the remaining batter and smooth the top. For a swirl effect, run a knife through the batter in a gentle S pattern.
- Bake: Bake for 40–50 minutes until the top is golden and a toothpick comes out mostly clean with a few moist crumbs. If the top browns too quickly, tent loosely with foil for the last 10 minutes.
- Cool properly: Let the bread cool in the pan for 15 minutes, then lift it out and cool completely on a rack. Keto breads firm up as they cool, so resist slicing too early.
- Optional glaze: Mix 1/3 cup powdered keto sweetener with 1–2 tablespoons heavy cream and a splash of vanilla until smooth. Drizzle over the cooled loaf.
Why This Recipe Works
This bread uses a combination of almond flour and a touch of coconut flour for a balanced texture—moist, but not dense. The cinnamon swirl is sweetened with a keto-friendly sweetener, giving you all the taste of a traditional loaf without the carbs.
Greek yogurt (or sour cream) adds richness and helps with moisture and rise. A small amount of baking powder and an optional pinch of xanthan gum improve structure so the bread slices cleanly. It’s simple to make, easy to customize, and bakes up with a beautiful golden top.

How to Make It
- Prep your pan and oven: Heat the oven to 350°F (175°C).
Line a 9×5-inch loaf pan with parchment and lightly grease it so the bread lifts out cleanly.
- Mix dry ingredients: In a large bowl, whisk 2 cups almond flour, 2 tablespoons coconut flour, 2 teaspoons baking powder, 1 teaspoon cinnamon, and 1/4 teaspoon salt. Add a pinch of xanthan gum if using.
- Whisk wet ingredients: In another bowl, whisk 4 large eggs, 1/2 cup granular keto sweetener, 1/2 cup melted butter, 1/2 cup full-fat Greek yogurt, and 1 teaspoon vanilla. Make sure the butter is cooled so it doesn’t scramble the eggs.
- Combine: Pour the wet mixture into the dry.
Stir until just combined. The batter will be thick but spreadable. Avoid overmixing to keep the crumb tender.
- Make the cinnamon swirl: In a small bowl, mix 2 tablespoons granular sweetener with 1 to 1.5 teaspoons cinnamon.
This creates the ribbon of cinnamon throughout the loaf.
- Layer the batter: Spread half the batter in the pan. Sprinkle the cinnamon mixture evenly over it. Add the remaining batter and smooth the top.
For a swirl effect, run a knife through the batter in a gentle S pattern.
- Bake: Bake for 40–50 minutes until the top is golden and a toothpick comes out mostly clean with a few moist crumbs. If the top browns too quickly, tent loosely with foil for the last 10 minutes.

Drizzle over the cooled loaf.
How to Store
- Room temperature: Keep sliced bread in an airtight container for up to 2 days.
- Refrigerator: Store up to 5–6 days. Warm slices in the microwave for 10–15 seconds to refresh the texture.
- Freezer: Slice, wrap individually, and freeze for up to 3 months. Thaw at room temperature or toast gently.
Health Benefits
This bread is low in net carbs thanks to almond and coconut flours, which are naturally grain-free and higher in fiber than wheat flour.
Using a keto-friendly sweetener helps avoid blood sugar spikes, making it a good option for low-carb lifestyles. Butter and yogurt provide satisfying fats that help with fullness and steady energy. Cinnamon adds warm flavor and can support balanced blood sugar as part of a healthy diet.
Common Mistakes to Avoid
- Overbaking: Keto breads dry out fast.
Start checking at 40 minutes and pull it once a toothpick has just a few moist crumbs.
- Cutting too soon: Slicing while hot can crumble the loaf. Let it cool to set the structure.
- Using coarse almond meal: Super-fine almond flour yields a better crumb. Coarse meal makes it gritty and dense.
- Too much sweetener: Over-sweetening can cause crystallization or a cooling aftertaste.
Measure carefully and choose a blend you like.
- Skipping parchment: Keto breads can stick. Line the pan for easy removal and clean slices.
Recipe Variations
- Pecan Crunch: Fold 1/2 cup chopped pecans into the batter or sprinkle on top before baking.
- Cream Cheese Swirl: Beat 4 ounces softened cream cheese with 2 tablespoons powdered keto sweetener and 1 egg yolk. Dollop over the first layer of batter and swirl.
- Apple Pie Vibe (Still Keto): Add 1/4 teaspoon apple pie spice and 1/2 teaspoon apple extract to the batter.
- Maple Cinnamon: Swap vanilla for 1 teaspoon maple extract and use a maple-flavored keto syrup as a light drizzle.
- Chocolate Chip Cinnamon: Fold in 1/3 cup sugar-free dark chocolate chips for a cinnamon-roll-meets-cookie feel.
FAQ
Can I use only almond flour and skip the coconut flour?
Yes, but the texture will be slightly denser and more moist.
If skipping coconut flour, add about 3–4 extra tablespoons of almond flour to balance the batter.
Which sweetener works best?
A monk fruit–erythritol blend is reliable and bakes well. Allulose gives a softer crumb and less cooling effect but can brown faster, so keep an eye on the top.
How do I know it’s done?
Look for a golden top and a toothpick that comes out with a few moist crumbs, not wet batter. The loaf will continue to set as it cools.
Can I make this dairy-free?
Yes.
Use coconut oil instead of butter and a thick dairy-free yogurt (like coconut yogurt). The flavor will shift slightly but still tastes great.
What if I don’t have xanthan gum?
You can skip it. The bread will still hold together, though slices may be a touch more delicate.
Let it cool completely before slicing.
Can I bake this as muffins?
Yes. Divide batter into a lined muffin tin and bake at 350°F (175°C) for 18–24 minutes, depending on size. Start checking at 18 minutes.
How many carbs per slice?
Exact macros vary by brand, but a typical slice (1/12 of the loaf) is around 3–4g net carbs without glaze.
