These Healthy Gluten-Free Blueberry Muffin recipe is my first muffin recipe on my website and boy, are these ever good! With over 10 grams of fibre and under 2 grams of sugar in each muffin, these low carb, healthy gluten-free Blueberry Muffins are definitely going to be made a lot at our house!

How on earth did I manage to get sooooooo much fiber in such a small bundle of goodness?

The secret?

Oat fibre!!

What is Oat Fibre?

Oat fiber is an ingredient low in carbs and absorbs up to seven times its weight in water. When added to baked goods, oat fibre creates a high fibre flour great for bulking up muffins, cakes and loaves of bread.

What is the nutritional value of 1/4 cup of Oat Fibre?

Calories - 0 Fat 0 g Saturated Fat 0 g Cholesterol 0 mg Carbohydrate 12 g Fiber 12 g Sugar 0 g Sugar Alcohol 0 g Protein 0 g

As you can see, all the carbs come from fibre.

Therefore, this makes oat fibre virtually non-digestible and doesn’t provide any carbs.

You can use it in baking as a flour substitute, usually with a blend of other low carb flours such as coconut flour and almond flour.

Since it is high in fibre, do not expect baked goods to be very light and fluffy when using this flour. Oat fibre creates a much denser end product.

So, where can you buy oat fibre?

I buy my low carb oat flour online but you can probably find it in health food stores.

Amazon sells a 5lb bag of oat fibre for $18.99 (currently there is a $1 off coupon which brings the price down to $3.50/lb). I always buy mine in bulk as the 1 lb bag is $4.99!

I highly encourage you to buy the large bag as you can add this flour to numerous baked goods.

Plus, if you follow me, you will need the big bag as I will continue to add it to all of my baked goods to increase the fibre content of my gluten-free recipes!

What if I don't have any gluten-free Oat Fiber to make this recipe?

If you don't want to use oat fibre, simply take gluten-free oats and throw them in a high-speed blender for a couple of seconds or until a flour-like consistency is achieved and replace the oat fibre with the oat flour.

It will increase the carbs in each gluten-free and low carb muffin but the deliciousness will remain!
