Are There Carbs in Blueberries?
There are approximately 9 net carbs in a half a cup of blueberries. For this low carb blueberry muffin recipe, there is 3/4 cup blueberries in the whole recipe.
Are Blueberries Keto?
Most all berries are perfectly fine on Keto. But, they are still a fruit and contain natural sugar. For this reason, blueberries, like all berries, should be eaten in moderation.
Not only is the carb count in blueberries acceptable on Keto, they are very nutritious. They’re a good source of manganese and vitamins C and K1. You can read this article to find out much more about all the health benefits of blueberries.

Tips for Almond Flour Muffins
- Baked goods made with almond flour tend to be delicate when they’re first removed from the oven. To avoid having your low carb blueberry muffins from breaking, let them cool in the muffin tin for about 20 minutes, then transfer them to a rack to cool completely.
- In order to keep muffins from having an eggy taste, make sure to always use room temp eggs before adding them to the other ingredients.
- To prevent Keto muffins from having a grainy texture, always use super fine almond flour, not almond meal or regular ground almond flour.
- To make sure you always have the freshest flour, keep your almond flour in the fridge once the package has been opened.
- To reheat these muffins, place them on a microwave safe plate, cover with a damp paper towel and reheat for about 10 seconds.
Substitutions for Gluten Free Blueberry Muffins
- For the purpose of this recipe, fresh blueberries were used, but you can certainly use frozen. The key to making frozen blueberries work is to add then to the batter while still frozen. This will help keep them from becoming too soggy.
- If you’d like to use another berry in this Keto muffin recipe, strawberries, raspberries or blackberries are a great choice.
- This recipe is so versatile, you can even add nuts. Finely chopped pecans and macadamia nuts compliment the other flavors in the this recipe well.
- If you like almond flavor, you can use almond extract instead of or along with the vanilla extract.
Is Oat Fiber Keto?
The Oat Fiber is really important in this recipe! I use it in so many recipes, because of the amazing texture it gives whatever I’m baking! It is hands down, the best ingredient I’ve baked with! The Oat Fiber that I use is made by Lifesource Foods, because they grind it to a very fine powder and has a mild flavor. I buy it in the 16 ounce bag, which lasts a while, because you don’t need to use much in your recipes.
Oat Fiber is not the same as Oat Flour, which is made from grinding oats. Oat Fiber is made from grinding the outer husks of oats and is pure insoluble fiber. Insoluble fiber doesn’t dissolve in water and is not broken down in the digestive tract, so it has zero net carbs and is Keto friendly.
