Key ingredients & substitutions

  • Almond flour  & coconut flour – The best combination of keto flours is almond flour and coconut flour. Together they form a flour that is closest in consistency and taste to all-purpose flour. This blend is my favorite gluten-free flour combo because they are readily available at most supermarket too.
  • Butter & coconut oil – The fat added to these muffins to help make them moist and spongy.
  • Cream cheese – Used to neutralize the flavor from the almond flour, coconut flour, eggs and coconut oil.
  • Sweetener – Powdered sugar free sweetener works best since it dissolved fully in the muffin batter. Look for one that measures cup for cup with regular sugar.
  • Sour cream – Used to neutralize the nut flours, coconut oil and egg flavor in this recipe. The combination of the acid from the sour cream and the baking powder will also help these muffins rise. To substitute sour cream, use Greek yogurt instead. 
  • Eggs – Use for structure and to help puff up these muffins to give that a perfect muffin top.
  • Lemon – For the best lemon flavor to the muffins use fresh squeezed lemon juice and lemon zest. However, bottle lemon juice will work and so will lemon extract.

  • Three glaze topped blueberry muffins next to whole blueberries and lemon slices.

    Lemon glaze

    For the sweet treat, try topping these muffins with a lemon glaze made from freshly squeezed lemon juice and powdered erythritol. I love the look of the glaze drizzled on these keto lemon blueberry muffins. It reminds me of a pastry treat you would find at Starbucks or other coffee shop.

    Storage information

    To keep these muffins fresh, store them in an air tight container at room temperature. Keto sweeteners don’t hold onto moisture like regular table sugar does so they tend to dry out faster.

    If stored properly, these keto muffins should stay fresh for up to a week. You can freeze them for up to 1-2 months.

    Keto Lemon Blueberry Muffins: FAQS

    Are blueberries keto?

    Blueberries are fine to eat on the keto diet in moderation. They can be higher in carbs compared to other berries. One cup of blueberries has 17.8 grams net carbs. So don’t eat a full cup of blueberries! But it’s okay to use them in a recipe as long as there are multiple servings.

    What sized muffins can I make?

    For this recipe you can make normal sized muffins or mini muffins. Either way I recommend using liners to ensure that your muffins don’t stick to the sides of the muffin tin.

    Can I use fresh or frozen blueberries?

    Fresh blueberries will also taste the best; however, frozen blueberries can be used in the keto blueberry muffin recipe as well. Sometimes frozen blueberries can cause the muffin bread to turn a blue hue before baking.

    1. I absolutely Love Love Love this recipe and so does my mom, husband and mother-in-law. Thank you for sharing it. Next I’m trying the pumpkin spice granola.

    2. I have attempted the keto diet many times and always fail. I am once trying once again as we go into 2021. I have been watching your youtube videos and studying your recipes on your site. I made these lemon blueberry muffins today and they are wonderful!! Maybe with some of your recipes and tips, I will finally be successful. Thank you so much.

    3. These muffins are intensely lemony but so delicious when you are craving sweets! Glad I made them and will do so again!

    5. We really enjoyed these a lot. I added a little zest to the frosting too! Thank you for sharing this recipe.

    6. I was recently diagnosed diabetic and these look great for a treat for me! Is it possible to freeze these or do half a recipe?

    7. Thank you so much for this recipe, you have changed my life and I graciously want to thank you. I have needed something like this, I’ve lost 23 pounds and I was stalled, these were absolutely amazing. Thank you so much

    8. OMG!!!! Okay I’m starting off on keto–only been on it for a little over a week. Was craving something sweet, but have not cheated in terms of eating anything that I’m not allowed. On top of it, I have a really bad tree-nut allergy (I can have peanuts but NOT coconut with my particular allergy) so I can’t have coconut flour OR almond flour! But, I decided to give your recipe, with 3 substitutions a try.

      I substituted the coconut oil with ghee (clarified butter)
      I used cauliflower flour and arrowroot flour for the almond and coconut (arrowroot being the substitute for coconut, cauliflower flour the substitute for almond)

      They STILL came out–Nice, fluffy, and still SOOOO Tasty!!!! next time am going to try substituting sunflower seed flour for the almond but…YAY!!!!

      I have a feeling that I’m going to be trying soo many more of your recipes–just so so good! Thank you!!!! I was scared to try keto because of my allergy, but I’m slowly, but surely, finding ways around it!!!:)

    9. Question… these sound wonderful but I am allergic to Lemon “Zest” I can have lemon extract, lemon juice, lemon stevia just cannot have the zest itself. how should I alter your recipe so I can make these…

      1. You could use either. I don’t think it needs to be altered, just add it in and taste until you like the flavor.

      2. Add 1/2 tsp of citric acid (powdered Vitamin C you can buy at any health food store) and you will get that great lemony zip you are looking for!

    10. I recently got diagnosed with gestational diabetes and I was craving some muffins. I have one as a snack with a bit of double cream on top! Delicious!

    11. Thank you for posting this recipe, absolutely amazing! The blend of the flours helps with the texture of the almond flour and the cream cheese gives a great background flavor. My husbands a diabetic and it’s tough finding recipes that’ll work for him that also taste good.
