Keto/Low Carb Lemon Poppyseed Muffins

I’ve been craving muffins lately. First, I made Keto/Low Carb Mixed Berry Muffins, so I started thinking about other flavors of muffins I love, and Lemon Poppyseed came to mind. Since I had already tweaked the basic muffin recipe, I just needed to experiment with how much lemon zest and lemon juice to add. There is a fine line between the perfect amount and a tad too much.

We ate these Keto/Low Carb Lemon Poppyseed Muffins for breakfast the rest of the week. I warmed them up each morning in the air fryer, then served them with a big slice of butter on top and bacon. My three-year-old woke up asking for more ‘lemony muffins’ this morning, so it looks like it’s time to bake more. Depending on your family size, you may want to double the recipe to make a big batch. This recipe is straightforward and comes together so quickly.

Lemon Poppyseed Muffin Ingredients:

  • Eggs– For this keto muffin recipe, you will need to use six eggs. I promise these Keto Lemon Poppyseed Muffins won’t be eggy. Keto-friendly flours bake very differently than regular gluten-filled flour and require more moisture.
  • Melted Butter– I like to melt my butter in the microwave to make things easy. Cut 9 tbsp of butter and place it into a microwave-safe dish—heat butter at 50% for 60 seconds. Add more time if needed. 
  • cream cheese– My go-to when it comes to cream cheese is Philadelphia cream cheese, but other brands work well too. 
  • Vanilla extract – A little vanilla adds a lot of flavor, so don’t forget to add it.
  • Heavy Whipping Cream–Made from skimming the high-fat cream from dairy milk. Its high-fat content makes it the perfect ingredient for your keto lemon poppyseed muffins.
  • Coconut Flour– This flour is super absorbent, so a little goes a long way. Plus, it adds a little bit of sweetness to your recipe!
  • Salt– A sprinkle of salt helps balance the flavor and bring out the sweetness in your muffins. 
  • Baking Powder– No one likes flat lemon poppy seed muffins! Adding 1 ½ tsp of baking powder will make your muffins look just like the ones in the store.
  • Swerve Granulated– My go-to keto sweetener. Great taste with zero carbs and no sugar.
  • Lemon Zest and Juice– To give your lemon poppyseed muffins some flavor, add lemon zest and lemon juice to the recipe.

Step 1: Preheat the oven to 350. Melt the butter in a large mixing bowl. I like to heat mine in the microwave at 50 percent. Beat eggs together with a whisk.

Step 2: Add your keto-friendly sweetener. I listed alternatives to Lakanto Monk Fruit Sweetener Classic in the recipe card notes at the bottom of this post.

Step 3: Mix eggs, sweetener, cream cheese, heavy whipping cream, vanilla, salt, and baking powder until combined.

Step 4: Zest and juice two lemons. This keto muffin recipe requires about 1/8th of a cup of lemon juice. Measure out before pouring.

Step 5: Add melted butter, coconut flour, lemon zest, lemon juice, and poppyseeds to the muffin mixture and beat again until combined.

Step 6: Pour batter into lined muffin pans in a muffin pan. I’ve been using parchment paper muffin liners I bought on Amazon (here) and loved them! Coconut flour tends to stick to muffin tins. Nothing sticks to parchment paper.

Step 7: Bake keto lemon poppyseed muffins in a 350-degree oven for 25-30 minutes.

ENJOY! Serve your keto lemon poppyseed muffins with piping hot butter.


If you have leftover keto lemon poppyseed muffins and want to save them for later, don’t worry, they store well! When storing your keto muffins for short periods, I recommend keeping them in the refrigerator. If fully covered, they should last about a week. Pull them out whenever you’re hungry, for the perfect keto breakfast or pick-me-up snack!

If you want to store muffins for a more extended period, I suggest individually wrapping the muffins in a zip lock bag before placing them in the freezer. They should keep for about six months. 


Yes! In this keto lemon poppyseed muffin recipe, you can use almond flour as a substitute for coconut flour. I choose to use coconut flour due to my daughter’s nuts allergy. Coconut flour is much more absorbent than almond. For every ¼ cup of coconut flour, you need 1 cup of almond flour. This recipe requires 2 cups and 4 tsp of almond flour. 

Note: I have not tested these low carb muffins with almond flour. The substituion is a general substitution. The texture of keto and low carb baked good have aa different texture than muffins made with regular flour.


Not only are these keto lemon poppyseed muffins delicious, but they also have some great health benefits! When it comes to seeds, poppyseeds tend to get overlooked. However, poppy seeds are a great addition to your baked goods, adding crunch and nutritional value. Did you know one teaspoon of poppy seeds has enough calcium and phosphorus to meet 4% of your recommended daily intake, 2-3% of your zinc, and 2-4% of your iron intake? These nutrients help your body create strong bones, cells, and a healthy immune system.

    1. I’ve only made it as is with the sweeteners listed, so I can’t say for sure from personal experience.

    It feels sinful. They are so good. As eating lemon cake with poppy seeds.
    Made 1/2 a portion with lime instead of lemon and put them in the air fryer for 13 minutes. So good.

    1. So glad you loved them. I bet they are yummy with lime! I’ll have to try making them in the airfryer.

  2. 5 stars
    I made this recipe as written and it turned out great! Definitely a keeper! Thank you for the recipe.
