Tips & Tricks

Here are a few important tips for these yummy blueberry almond flour muffins

  • You can blend the batter in a food blender (this is the one I use from Amazon) and stir in the blueberries, or blend it all together. This gives a fun purple tint to the muffins.
  • Make sure you use either paper liners or a silicone muffin tray. I’ve found these non-stick silicone muffin pans on Amazon really convenient for keto baking, and they help prevent sticking.

  • If you’re greasing your muffin tin, do it with butter instead of oils. Oils like coconut oil or cooking spray don’t always prevent sticking with almond flour muffins.
  • When making blueberry muffins with sour cream, expect a subtle tangy flavor—similar to what you’d get with buttermilk. If you’d prefer a more neutral taste, you can swap it out with a keto-friendly option like unsweetened almond milk.

How to Make Keto Blueberry Muffins With Sour Cream

To start, gather all of the ingredients you need to make these keto muffins in one place. Also, preheat the oven to 350F and line a 6-hole muffin tin with paper liners.

 Next, in a bowl, combine almond flour, Swerve, and baking powder.

Then add the eggs, coconut oil, sour cream, and vanilla if using, and stir well to combine. While all of these wet ingredients listed here will add some moisture to the batter. If you find that your batter isn’t as moist as you’d like add an extra tablespoon of water or almond milk to make it a little thinner. The muffins will be fluffier for it.

Lastly, fold in the blueberries.

Spoon the keto sour cream blueberry muffin mixture into paper liners. This recipe will make six muffins.

How to Store Keto Sour Cream Muffins

These low carb blueberry muffins will keep out of the fridge for up to 3 days. You can also store them in the fridge for up to 5 days or freeze them for 2-3 weeks. Thaw and reheat in the oven at 300F when you’re ready to enjoy them.

Recipe Substitutions for Sugar Free Blueberry Muffins

You can substitute with any nut-based flour or even make these with protein powder rather than almond flour. 

You can also use any kind of berries such as raspberries or strawberries. Make sure to chop or slice the strawberries before use. 

Also, instead of berries, you can add slivered almonds to the muffins. Or combine the almonds with the berries. They will give a nice crunchy texture to your muffins.

Keto Blueberry Muffins with Heavy Cream

You can also make these into keto heavy cream blueberry muffins if you like. Heavy cream is richer and fattier than sour cream, but it works just fine. 

3 tablespoons of sour cream can be swapped out for 3 tablespoons of heavy cream.

How Many Carbs are in Blueberry Muffins?

A regular blueberry muffin made with ingredients that are not keto-friendly can have as much as 68 grams of carbs. These low carb blueberry muffins, on the other hand, have only 2.5 grams of net carbs in each muffin which means you can eat this with absolutely no guilt. 

How to Make Blueberry Muffins with Coconut Flour?

Making these with coconut flour on its own is not recommended as the muffins may turn out too dense and will not raise. However, you can use a mix of 1 cup of almond flour and 0.25 cups of coconut flour or a 1:4 ratio.

Can these Low Carb Muffins be Made in a Mug?

You can make these in a mug. Make the batter as shown above (of course scale down) and divide it among the microwave-safe mugs. For one muffin you will need 1 small egg, 3 tbsp almond flour, baking powder from the tip of a knife, 1 tsp coconut oil, 1 tbsp sour cream, and 2 tbsp blueberries. Microwave for 2 minutes.

Can these be Made with Heavy Cream?

To make it with heavy cream, simply substitute the milk in the recipe with heavy cream.

Can You Make Blueberry Muffins with Yogurt?

Yes, these can be made with yogurt. To make it with yogurt, replace the 3 tablespoons of sour cream milk with 3 tablespoons of yogurt.
