Why These Cinnamon Rhubarb Muffins Are a Must-Try
These Cinnamon Rhubarb Muffins are more than just a gluten-free delight; they offer a perfect balance of sweet and tart, with the rich, aromatic flavor of cinnamon. The use of almond and coconut flour makes them ideal for those on a low-carb or keto diet.

They are ideal for busy mornings or as a snack to enjoy with a hot cup of coffee.
Ingredients for Cinnamon Rhubarb Muffins
Before diving into the recipe, let’s take a look at the ingredients that make these muffins so special:
• Almond Flour: Provides a nutty flavor and moist texture while keeping the muffins low-carb and gluten-free.
• Coconut Flour: Adds a slight coconut taste and helps to absorb moisture, ensuring the muffins are soft and fluffy.
• Low-Carb Sweetener (Swerve or another alternative): A sugar-free sweetener that maintains sweetness without the carb content.
• Baking Powder: Helps the muffins rise, creating a light and airy texture.
• Cinnamon: Adds a comforting spice and pairs perfectly with the tartness of the rhubarb.
• Salt: Balances the sweetness and enhances the flavors.
• Xanthan Gum (Optional): Helps improve the texture, especially in gluten-free baking, by providing structure.
• Sour Cream: Adds richness and moisture, contributing to a tender crumb.
• Unsalted Butter: Ensures a buttery flavor and helps the muffins bake to perfection.
• Egg: Binds the ingredients together and provides structure to the muffins.
• Vanilla Extract: Adds depth and warmth to the flavor profile.
• Diced Rhubarb: The star of the recipe, providing a tart and refreshing taste that contrasts beautifully with the sweetness of the muffins.
Ingredient Swaps and Suggestions
While the recipe is designed to be low-carb and gluten-free, you can still tweak it to fit your dietary preferences. Here are some alternatives:
• Rhubarb: If you don’t have rhubarb, you could try using berries, such as strawberries or blueberries, for a sweeter twist.
• Almond Flour: You can substitute almond flour with sunflower seed flour if you have nut allergies.
• Butter: For a dairy-free version, use coconut oil or olive oil in place of the butter.
• Sour Cream: If you don’t have sour cream, Greek yogurt is a great substitute.

Step-by-Step Instructions for Cinnamon Rhubarb Muffins
Making these Cinnamon Rhubarb Muffins is straightforward. Follow these simple steps to create your own batch of warm, flavorful muffins:
- Preheat your oven to 325°F (163°C). Prepare your muffin pan by either greasing it or lining it with paper muffin cups.
- In a large bowl, combine the dry ingredients: almond flour, coconut flour, baking powder, cinnamon, salt, and xanthan gum (if using). Stir well to ensure everything is evenly mixed.
- In a medium bowl, mix the wet ingredients: whisk together the sour cream, melted butter, egg, and vanilla extract until smooth.
- Combine the wet and dry mixtures. Add the wet ingredients to the dry ingredients, stirring until just combined. The batter will be thick.
- Stir in the diced rhubarb, ensuring it is evenly distributed throughout the batter.
- Scoop the batter into the muffin pan, dividing it evenly between the 6 muffin cups.
- In a small bowl, combine the topping ingredients: low-carb sweetener and cinnamon. Sprinkle this mixture evenly over the muffins.
- Bake for 25 to 30 minutes, or until the muffins are golden brown and a toothpick inserted into the center comes out clean.
- Cool the muffins on a wire rack for about 10-15 minutes before serving.
Tips & Tricks for Perfect Cinnamon Rhubarb Muffins
- Don’t overmix the batter: Overmixing can result in dense muffins. Stir until just combined to ensure a light texture.
- Check for doneness: Insert a toothpick into the center of the muffins to check if they’re done. It should come out clean, but moist.
- Grease the pan: If you’re using paper muffin liners, consider greasing them slightly to prevent the muffins from sticking.
- Store leftovers: These muffins can be stored in an airtight container in the fridge for up to 3 days. Reheat in the toaster oven for 5-10 minutes for the best texture.
Pairing Ideas and Variations
These Cinnamon Rhubarb Muffins are incredibly versatile and can be paired with various side dishes or beverages:
• Serve them with a dollop of whipped cream or a splash of almond butter for an extra boost of flavor.
• Pair with a hot cup of tea or coffee for a cozy breakfast or afternoon snack.
• For a more indulgent treat, drizzle with a sugar-free glaze or enjoy with a side of Greek yogurt.
Why These Cinnamon Rhubarb Muffins Are a Healthy Choice
Not only are these muffins delicious, but they are also packed with nutrients. Rhubarb is an excellent source of vitamin C and fiber, making these muffins a great addition to a balanced diet. With only 3 grams of net carbs per muffin, they’re perfect for those following a keto or low-carb lifestyle. Plus, using almond and coconut flour keeps them gluten-free, making them suitable for those with gluten sensitivities or celiac disease.

They offer a great way to enjoy the distinct flavor of rhubarb without the added sugar and carbs. Whether you’re new to gluten-free baking or a seasoned pro, this recipe is sure to become a favorite.

Frequently Asked Questions (FAQ)
Can I use regular flour instead of almond and coconut flour for these muffins?
While almond and coconut flour are essential for keeping these muffins gluten-free and low-carb, you can use regular flour if you’re not following a low-carb diet. However, the texture and flavor of the muffins may change slightly, and the recipe will no longer be gluten-free.
How can I make these muffins sweeter?
If you prefer your muffins a little sweeter, you can increase the amount of low-carb sweetener in the recipe. You can also add a bit of natural sweetener, such as stevia or monk fruit, to taste. Just be sure to check the sweetness level as you go.
Can I substitute rhubarb with other fruits?
Yes, you can substitute rhubarb with other fruits like strawberries, blueberries, or raspberries. Keep in mind that rhubarb has a unique tartness that may not be fully replicated with other fruits, but these alternatives will still create delicious muffins.
How do I store leftover muffins?
To keep your muffins fresh, store them in an airtight container in the refrigerator for up to 3 days. Reheat them in a toaster oven for 5-10 minutes to restore their warmth and texture. You can also freeze them for up to 3 months – simply wrap them tightly in plastic wrap or aluminum foil before freezing.
