Keto Cinnamon Bun Muffins are soft, fluffy, and packed with all the sweet, spicy flavors of a classic cinnamon bun, without the sugar or flour. They are perfect for breakfast, brunch, or a low-carb snack. These muffins use almond flour and coconut flour for a light texture, while a buttery cinnamon swirl and optional cream cheese glaze elevate them to indulgent, keto-friendly treats.
Ingredients
Dry Ingredients
- 1 1/2 cups almond flour (blanched, finely ground)
- 2 tablespoons coconut flour
- 1/4 cup powdered erythritol or monk fruit sweetener
- 1 teaspoon baking powder
- 1/2 teaspoon baking soda
- 1/4 teaspoon salt
Wet Ingredients
- 3 large eggs, room temperature
- 1/3 cup unsweetened almond milk (or heavy cream for richer muffins)
- 1/4 cup melted butter or coconut oil
- 1 teaspoon vanilla extract
Cinnamon Swirl
- 2 tablespoons butter, melted
- 2 tablespoons powdered erythritol
- 1 teaspoon ground cinnamon
Optional Glaze
- 2 tablespoons cream cheese, softened
- 1 tablespoon unsalted butter, softened
- 1–2 tablespoons powdered erythritol
- 1 teaspoon vanilla extract
- 1–2 teaspoons almond milk (to thin, if needed)
Equipment Needed
- Muffin tin (6–8 cups)
- Paper liners or non-stick spray
- Small bowl for cinnamon swirl
- Whisk or mixing bowls
- Spoon or piping bag (optional for swirl)
Instructions
Step 1: Preheat Oven
- Preheat your oven to 350°F (175°C).
- Line a muffin tin with paper liners or lightly grease with non-stick spray.
Step 2: Make the Dry Mixture
- In a large bowl, whisk together almond flour, coconut flour, powdered sweetener, baking powder, baking soda, and salt.
- Ensure there are no lumps, especially in the coconut flour, which can clump easily.
Step 3: Mix Wet Ingredients
- In a separate bowl, whisk together eggs, almond milk, melted butter, and vanilla extract until smooth.
- Gradually add the dry ingredients to the wet ingredients.
- Stir until just combined to form a thick, slightly sticky batter. Do not overmix.
Step 4: Prepare Cinnamon Swirl
- In a small bowl, mix melted butter, erythritol, and ground cinnamon until smooth.
- Set aside for swirling into the muffins.
Step 5: Assemble Muffins
- Spoon half of the batter into the muffin cups.
- Drop small spoonfuls of the cinnamon mixture evenly over the batter.
- Top with remaining batter.
- Use a toothpick or skewer to gently swirl the cinnamon mixture through the batter to create a marbled effect.
Step 6: Bake
- Bake for 18–22 minutes, or until a toothpick inserted in the center comes out clean.
- Let the muffins cool in the tin for 5 minutes, then transfer to a wire rack to cool completely.
Step 7: Optional Glaze
- In a small bowl, beat cream cheese, butter, powdered sweetener, and vanilla extract until smooth.
- Add almond milk, 1 teaspoon at a time, until a drizzling consistency is achieved.
- Drizzle glaze over cooled muffins for a sweet finish.
Helpful Tips
- Coconut flour absorbs liquid, so do not skip it; it helps create structure.
- Let muffins cool completely before adding glaze to prevent melting.
- Use fine powdered sweeteners for smooth texture; granulated sweeteners may leave a gritty texture.
- Store in an airtight container in the fridge for longer shelf life.
Serving Suggestions

Storage and Freezing
