These bright and fresh glazed coconut flour keto lemon poppy seed muffins (or keto lemon bundt cake!) are soft, tender, and perfectly sweetened with a nice lemony flavor.
Are you more of a chocolate dessert person or a lemon dessert person? I personally love all things chocolate, but every now and then I want something more summery and light.
These almond flour keto lemon poppy seed muffins are light, refreshing, perfectly moist, and perfect for summer. Or if it's not summer, they will brighten the coldest of days!
The muffins aren't overpowering with lemon flavor, but still have a refreshing lemon taste with a good balance of sweet and tart. They also have a light crunch of poppy seeds and a silky lemon glaze that makes them an instant hit!
And even though these are naturally a little heavier than say an Angel Food Cake or Vanilla Cake, they're still super moist, soft, and cakey.
Frequently asked questions
Coconut flour is a very unique flour, and unfortunately, cannot be substituted.
Yes, not all coconut flours are made the same! I recommend using Bob's Red Mill, Besti, or Arrowhead Mills Coconut Flour. If you choose to use another brand, make sure the texture is thick, soft, and fluffy. Not grainy. Otherwise, the cake will turn out too wet and be heavy.
Ingredients
The ingredients are super-simple and most keto pantries are already stocked with them. Here's what you'll need:
- Coconut Flour
- Sea Salt
- Baking Powder
- Baking Soda
- Keto Sweetener
- Poppy Seeds
- Pure Vanilla
- Avocado Oil
- Lemons
- Eggs
And for the glaze you'll need the following:
- Keto Powdered Sweetener
- Lemon Juice
- Water
The keto sweetener
I used to recommend using an erythritol-based sweetener, but I now recommend using xylitol or a monk fruit/allulose blend. They both have zero aftertastes and make the crumb extra soft! However, you can use an erythritol-based sweetener if you prefer.

🔪 Easy instructions
Step #1: Whisk together the dry ingredients.
This includes coconut flour, sea salt, baking soda, baking powder, sweetener, and poppyseeds.
Step #2: Whisk together the wet ingredients.
In a separate bowl, whisk together 4 room temperature eggs, pure vanilla, avocado oil, lemon juice, and lemon zest.
Cold ingredients can prevent the flours from mixing properly and interfere with how the cake rises. This is why I use room-temperature eggs.
Step #3: Pour the wet ingredients into the dry and mix well.
The batter will be thick, this is totally normal!
Step#4: Bake and serve.
For bundt cake
For a poppy seed bundt cake, pour or scoop the batter into a well-greased bundt pan and bake for 25 to 30 minutes.
While I haven't tried this recipe in a regular cake pan, I don't recommend it because I don't think it would rise properly. And besides, you would miss out on the beautiful bundt shape!
Try not to over-bake, which can dry out the cake. If the top starts to brown too quickly, loosely cover it with foil.
Turn the cake upside down over a wire rack and allow it to cool completely. Once cooled, carefully invert onto a cake plate.
For muffins
For keto lemon poppy seed muffins, fill each cup just over half full, and bake 18 to 22 minutes at 350 degrees. The batter will make approximately 18 muffins.
Allow to cool in the pan for 5 minutes, then transfer to a cooling rack to cool completely.
The glaze
For the glaze, whisk together some powdered keto sweetener with lemon juice, lemon zest, and water as needed to thin.
I prefer not to use an erythritol-based sweetener for the glaze because it tends to leave an aftertaste and isn't completely smooth.
My favorite sweetener for glazes is a powdered monk fruit allulose blend because it dissolves beautifully and leaves ZERO aftertaste!
Powdered allulose will also work. However, it's only 70% as sweet as other sweeteners so you'll need to add an additional ⅓ cup.
Drizzle the glaze over the keto poppy seed muffins or bundt cake and enjoy!!!
💭Tip: If you only have granulated sweetener, simply place it in a very dry blender and whirl until powdered. Then, measure out for the recipe 👍
How to store leftovers
The muffins or cake can be stored tightly covered at room temperature for 2 to 3 days or it can be frozen for up to 1 month.
If freezing, cool completely and, if freezing cake, cut it into individual slices without the glaze. Then wrap each piece in plastic wrap and place them in a freezer-safe baggie.
Top tips
- Grease the pan well. Even if it's a non-stick bundt pan, grease the pan well.
- Allow the cake to cool completely. If you try to remove the cake before it has cooled completely, it will stick to the pan and be a disaster.
- Use room temperature eggs. Using cold eggs can prevent the flours from mixing properly and interfere with how the cake rises.
- Don't skip the glaze! The glaze is simply fabulous and adds the perfect amount of sweetness and tanginess. Trust me, you don't want to miss it!
- Don't substitute the coconut flour. Coconut flour is very unique and this recipe will not work if the coconut flour is replaced with different flour. A word of caution: Not all coconut flours are made the same! I recommend using Bob's Red Mill Coconut Flour or Arrowhead Mills Coconut Flour. If you choose to use another brand, make sure the texture is thick, soft, and fluffy. Not grainy. Otherwise, the cake will turn out too wet and be heavy.
- Do Not Use A Cake Pan. Even though I have not tested this recipe in a cake pan, I don't recommend it because I don't think it would set up and rise properly.

Yummy, but it fell apart when trying to take it out of the pan. Used grapeseed oil instead of avocado oil.
Cassidy Stauffer says
Oh no, I'm sorry!!! This has never happened to me! Did you get the oil in all the crevices and allow it to completely cool? If it is even the slightest bit warm it will stick. Sorry again!

When baking any kind of cake—-ESPECIALLY in a Bundt pan, I grease it well and then sprinkle flour al over the entire surface. Then tap it around and dump any excess. I’ve never had a cake stick to my old Bundt pan doing this
