The Best Keto Lemon Poppy Seed Cake

This Keto Lemon Poppy Seed Cake is citrisy and refreshing and perfect for spring!

Lemon Poppy seed Cake

It’s supposed to be Spring; April is tomorrow, but I am staring out of the window, and all I see is snow. Lots of it.

I spent the weekend in Ohio to get a little reprieve from motherhood, and last night it snowed like 6 inches. It’s insane. The weather in Ohio is so bipolar, but eventually, Spring will be here, and I will greet it warmly with this Keto Lemon Poppy Seed Cake.

I love lemon flavor desserts. If you haven’t made my Coconut Lemon Zucchini Cake, you should try that one too, it’s AMAZING. The citrusy and sweet together is such a great combination, and it reminds me of all things warm.

Poppy seeds, on the other hand, remind me of my childhood. Growing up in a European household, we would always have poppyseed rolls. I remember I would always eat the inside and leave the crust. What is with that?

Now my daughter does that all the time, and it makes me so mad. Oftentimes, the crust is the best part!!

Anyways, this lemon flavor poppy seed cake is great when you are looking for something refreshing and sweet that is easy to make.

What kind of flour can I use for Lemon Poppy Seed Cake?

I used both Almond flour and Coconut flour but mostly almond. Coconut flour makes baked goods more “cake like” but it doesn’t hold together as well as almond flour. If you want your cake to be more “cakey” you can add more coconut flour.

How thick or thin should the batter be?

You should be able to pour the batter into the bundt pan, but it shouldn’t be pancake batter thin. If it’s too thick you can add in more coconut milk and if it’s too thin, add more flour.

Where can I get poppy seeds?

Poppyseeds are usually in the spices and seasonings aisle in the store. Also, you can check the baking aisle, and of course, you can get them on Amazon.

Can I use almond milk or heavy cream instead of coconut milk?

Yes, you can substitute the exact amount of coconut milk with almond milk. If you want to use heavy cream, I would only use half of the amount and you can add water if your batter is too thick.

It goes great with a cup of coffee or a glass of rosé too!! Invite some friends over, chill a bottle, and enjoy!

  1. This is the best keto cake recipes I have ever tried. The lemon and poppy seeds go so well together and it was so moist and not dry like other keto cake recipes I made before. Thank you!

  2. Hi Lesya! I’m excited to try this.
    If I wanted to do vanilla rather than lemon, do you think I could simply omit the zest and sub the lemon juice with nut milk?

  3. Hi K! Thank you for checking out my recipe. Yes, you can make adjustments to the recipe depending on your taste but if you want to achieve a citrusy flavor, I highly suggest not omitting the lemon. You can also check my other cake recipes that don’t use lemon juice. Check out this Keto Cinnamon Swirl Zucchini Cake. You’ll also love this.

  4. Hey David! Thank you for sharing this recipe. Can I use Stevia-Erythritol-Based Keto Granulated Sugar? And also, what size is the bundt pan? Thank you!

  5. Hi Milou! Lesya here, the owner of the blog. I’m glad you enjoyed the recipe! Yes, you can use Stevia-Erythritol-Based Keto Granulated Sugar for this recipe; it’s a great alternative. Regarding the bundt pan, I usually use a 9-inch pan for this recipe. Thank you for reaching out, and happy baking!

  6. Thanks for your question, Sarah! Substituting brown rice flour for coconut flour in this Keto Lemon Poppy Seed Cake might be a bit tricky since brown rice flour isn’t keto-friendly and has different absorption properties compared to coconut flour. If you’re not strictly following a keto diet and want to experiment, keep in mind that you may need to adjust the quantity since coconut flour is much more absorbent than brown rice flour. A general guideline is to use about 3 times more brown rice flour than coconut flour. Let me know how it turns out if you decide to give it a try. Happy baking!
