Keto Lemon Blueberry Muffins

When it comes to keto baked goods, my favorite recipes to make are cupcakes, cookies, and these keto lemon blueberry muffins. 

Every spring, like clockwork, my mom always gives me a massive bag of lemons. When I first moved out of home, I actually hated her giving me lemons because I had no idea what to do with them. To be quite honest, I actually would often give them away. 

It wasn’t until I started baking lemon flavored desserts that I begun to appreciate my mom’s gift’. It astounded me that supermarkets would sell lemons for up to $1.50 PER LEMON. Ever since that initial shock, I vowed never to take them for granted. This worked out well, as I developed a new obsession with adding lemon to recipes. If I wasn’t making a lemon cake or a lemon cheesecake, I would use them to make these lemon blueberry muffins! 

I’ve been meaning to share a keto lemon blueberry muffin recipe for quite some time. It’s been a fabulous spring muffin that highlights the perfect combo of lemons and blueberries. It’s a twist on my almond flour blueberry muffins, and It’s made in one bowl and uses simple ingredients.

No grains and no sugar are needed, but you’d never tell. The texture is moist, fluffy, and with a light and tender crumb. They are sweet and with a subtle lemon tang, without being overpowering! 

I had some friends over for coffee the other morning and NO ONE believed me when I said these were low carb- They thought I bought them from a bakery!

How do you make keto lemon blueberry muffins?

The Ingredients

  • Almond flourBlanched almond flour must be used, not almond meal. The latter will yield dense and hard muffins, instead of fluffy ones!
  • Granulated sweetener of choice– Either monk fruit sweetener, erythritol, or allulose can be used. 
  • Baking powder– Leavening agent to give some structure and rise for the muffins. 
  • Eggs– Room temperature eggs are preferred. 
  • Coconut oil– Melted and cooled to room temperature. 
  • Milk– I used unsweetened coconut milk, but any milk can be used. 
  • Lemon extract– Gives the muffins a lovely lemon flavor, without needing any lemon juice. 
  • Blueberries– Fresh or frozen. 
  • Powdered sugarKeto powdered sugar mixed with water to form a glaze.

The Instructions

Start by mixing together your dry ingredients until combined. Next, in a separate bowl, whisk together the wet ingredients. Slowly fold in the dry into the wet until combined. Fold through the blueberries. Let the batter sit for 5 minutes, to thicken. 

Now, distribute the muffin batter evenly amongst a 12-count muffin tin lined with muffin liners. Bake the muffins for 20-25 minutes, or until a skewer comes out mostly clean.

Tips to make the best low carb lemon blueberry muffins

  • Toss your blueberries in some flour before adding them to the batter. This will ensure they don’t sink to the bottom and are evenly dispersed. Reserve a few to top the muffins with.
  • Use lemon juice instead of water to make the glaze, especially if you want a more pronounced lemon flavor. 
  • Use silicone muffin molds for easy removal and minimal mess.
  • Avoid adding extra blueberries, as this can change the overall texture and cooking time. 

Storing and freezing almond flour lemon blueberry muffins

  • To store: Muffins will keep at room temperature in a sealed container, for up to 5 days. Store them in the refrigerator if you’d like them to keep longer. 
  • To freeze: Place muffins in a ziplock bag and store them in the freezer for up to 6 months. If you plan on storing the muffins in the freezer, omit the glaze.

For the glaze


  • Preheat the oven to 180C/350F and grease a muffin tin or 12-count silicone muffin pan and set aside.
  • In a large mixing bowl, combine all your dry ingredients and set aside. In a separate small bowl, add the rest of your ingredients, except your blueberries, and mix well.

  • Allow cooling in the pan for 5 minutes, before transferring to a wire rack. Drizzle with the glaze.

For the glaze

  • Whisk together the keto powdered sugar and lemon juice until thin.


* The lemon extract I used was very strong, and 1 tablespoon was plenty. If you prefer a more pronounced lemon flavor, add some lemon juice.

    I just made this recipe and love the texture and moisture. I’m not a fan of the lemon extract (too strong of perfumy smell and taste), so I will have to try again with lemon zest and lemon juice I suppose.

  2. I just made these gorgeous Blueberry Lemon muffins this evening.
    I haven’t tried one yet as they are not cooled completely but will be diving into one is a bit.
    I’ll let you know how they taste!

  3. These are my favorite blueberry muffins now. They taste so fresh and comfy! I added vanilla paste to the batter and half the lemon extract because my husband is usually not a lemon fan, and it was perfect. What I love about this recipe is that you can substitute out the lemon flavoring to anything you like. Probably berries too! It’s a great muffin base. They are a substantial size, almost the size of a full traditional muffin without the overflowing mounding top. Other Keto muffin recipes fall short by giving us a muffin that is only half the size of the muffin cup or a recipe that only makes 6 muffins. Unless you live by yourself and don’t have a freezer, that’s just a kick in the gut. LOL. But not yours! It’s proper, full, and fluffy. And tastes delicious. Thank you for such a great recipe, Arman.

    I’m new to keto and just trying out some recipes for the foods I love and will miss eating and I have to say I love all things lemon. I made these today, just tweaked it a little bit by whipping the egg whites up and I have to say they are delicious. Rather than glaze them I made a lemon drizzle as I’m not a fan of icing./glazes. I will definitely be making these again especially as I got 17 little muffins out of the mix so I can freeze them and when I get a sweet tooth moment all I need to do is raid the freezer :-). Thank you for the recipe, can’t wait to try more of your recipes.

    Hi Armen! I watch the amount of fat I eat each day so I was wondering if you can make this with egg whites instead of whole eggs?

  6. 5 stars
    Excellent flavor and texture. Thank you for this recipe!
    I used 3 T allulose and 3 T Lakanto granulated for the sweetener, added 1 tsp lemon zest, and used frozen blueberries. Dipped cooled muffins into glaze made with Swerve powdered and lemon juice.
    The whole family loved these and they will be in my regular rotation for keto/gluten-free baking.

  7. Hi Arman thanks for getting back to me. It just says almond flour on the front of the pack, but when I’ve looked in the ingredients it says, may contain other nuts, peanuts sesame seeds and gluten containing cereals. I take it that it should just be there? If that’s the case I’m a bit miffed as it cost me £9 for a 500g bag.

    Hi Arman I am new to keto and have never baked with almond flour before. When I opened the bag of flour it was a bit clumpy, so I thought I would sieve it so it was nice and fine. It was a right pain to do, took me ages just to do the 2 1/2 cups needed.I’m just wondering if this is the normal texture of almond flour and did I really need to sieve it. The muffins turned out lovely, but there was a bit of a grainy texture to them. I only bought the flour a couple of days ago and opened it today to make the muffins. Many thanks Sue

    1. Hi Sue! Was the blend blanched almond flour? It should be superfine and all the same color. Almond meal is more gritty and often yield a grainy texture.

  9. Please give additional tips on how to recreate your coconut butter glaze. What brand did you use? I tried Nutiva and Artisana. I shaved off thin shavings from the hard blocks that come in the glass jars, then sprinkled on the warm muffins. Minutes later, nothing had changed. They just staid as solid pieces on top of the muffins. I then tried to pre-melt it in a pot… but it wouldn’t really melt. Just became a thick kind of icing I guess, which had to be spread on top, but it still tried hard to stay together and resisted spreading. Again… nothing even close to a glaze. Please help! What am I missing?

  10. Please provide missing instructions regarding coconut oil… You don’t specify if this is cold right out of the jar, or melted first. Most baking recipes require melting, so if you don’t specify that, I’m guessing this is to be added cold and solid? If so, recipe should still clarify that… Otherwise we are left wondering if we are just supposed to KNOW to melt it on our own???? But I’m not that experienced to know for sure… Please help!!!

  11. Arman, will you delete my comment that has my full name … I apologize for being a pain in the butt … I just do not feel comfortable with my whole name out there … such a crazy world. I love your recipes btw … you are amazing!!

  12. Brenda, Did you try this recipe with fresh lemon juice? I was wondering the same thing but didn’t want to waste ingredients trying to see. My friend made the recipe exactly how he makes it and they are so delicious!!

  13. Hi! I am on a keto diet and have a question about the macros for the muffins. What is the net carb amount for just 1 muffin?

  14. One thing confuses me. These are suposed to be Paleo, which to my understanding means no dairy or grains. But the recipe contains baking powder which, unless you make your own, contains corn starch. What kind of baking powder do you use, Arman? I follow your recipes specifically to avoid gluten and corn. I appreciate your help. Thank you.

    1. Hi there, I used an aluminium free one! There are corn-starch free ones in supermarkets and health food stores.
