My classic keto pound cake recipe is one of my most popular keto dessert recipes. But this lemon poppy seed version? It’s definitely a solid rival. Instead of a loaf like the original, I made this one into a keto lemon bundt cake instead. Not only does this easy keto lemon pound cake with almond flour look impressive on a cake stand, it’s moist and delicious (much like lemon blueberry zucchini bread!) and takes only 15 minutes of prep time.

Once the lemon poppy seed bundt cake comes out of the oven (and it’s had time to cool!), it’s topped with a bright and sweet lemon glaze.

This low carb lemon pound cake recipe was originally published on March 17, 2018, and the post was republished in September 2020 to add useful tips.

I first made this keto bundt cake with almond flour for my daughter’s 3rd birthday a couple of years ago. It was such a hit with everyone that I’ve made it again and again since then – and I bet you will too, once you try it!

How To Make Keto Lemon Pound Cake

Let’s make lemon poppy seed bundt cake!

Prep bundt pan. Grease the bundt pan well.
Mix wet ingredients. In a large bowl, use a hand mixer to beat together butter and Besti Erythritol, until fluffy. Beat in eggs, sour cream, lemon extract, and vanilla extract.
Mix dry ingredients. In another bowl, stir together almond flour, baking powder, poppy seeds, and sea salt.
Combine wet and dry ingredients. Beat the dry ingredients into wet ones, 1 cup at a time.
Bake lemon poppy seed bundt cake. Transfer batter to the pan and smooth the top. Bake until the top is golden brown, then loosely cover with foil and bake until an inserted toothpick comes out clean. Let cool for at least 15 minutes, then turn out onto a cooling rack and cool completely.
Glaze. Whisk together Besti Powdered Erythritol, lemon juice, and vanilla extract. Drizzle glaze over your lemon poppy seed bundt cake and enjoy!

TIP: You can adjust the consistency of the glaze as needed. Just add more lemon juice if it’s too thick, or more sweetener if it’s too thin.

Keto Bundt Cake FAQs

What kind of almond flour should I use?

It’s important to use super fine blanched almond flour for this keto pound cake recipe. Do not use almond meal or a coarse almond flour – both of these would yield a more grainy result.

Can you make pound cake with coconut flour?

No, sorry, this gluten-free lemon poppy seed bundt cake recipe is designed to be with almond flour. Coconut flour won’t work. If you can’t have almond flour, you might want to try my coconut flour muffins and add some lemon zest or extract to them.

If you have a nut allergy, you could try sunflower seed flour, which would have a different flavor but could still work.

Can you make lemon poppy seed bundt cake with a different sweetener?

Yes, you can, as long as it’s the right kind. I originally made this keto lemon pound cake with granulated erythritol for the cake and powdered erythritol for the glaze, which is what the recipe card says below. (You definitely need granulated and powdered, respectively, for the right consistencies in the cake and filling.)

However, I have since also made it with allulose-based sweeteners and now prefer them. (Read about the differences in the keto sweetener comparison guide.) Using allulose-based sweeteners like the ones below will make for an extra moist cake! To do so, use the following:

Granulated sweetener for the cake – Swap the granulated erythritol on the recipe card with crystallized allulose, they are a 1:1 replacement! You could also use crystallized monk fruit allulose blend, but use 2/3 cup instead of 1 cup.
Powdered sweetener for the lemon glaze – Replace the powdered erythritol with powdered allulose, in the same amount. You can also try powdered monk fruit allulose blend instead, but in this case the amount will not change because you need a certain amount of sweetener for the right glaze consistency. (Your glaze will be sweeter with the blend!)

What is the difference between a pound cake and a bundt cake?

Technically, any cake made in a bundt pan is a bundt cake. But in most cases, the type of cake most often made in a bundt pan are pound cakes.

You can expect a gluten-free pound cake or bundt cake to have a moist, dense texture. Assuming that, the pan itself leads to two main differences:

Moisture is especially important in a gluten-free bundt cake, because there is more surface area than a traditional loaf pan or cake pan. So, a moist batter ensures that it isn’t dry. The good news? Making pound cake in a bundt pan means you get more delicious crusty edges!
Baking time varies depending on your pan. Shallower pans require less time in the oven, deeper ones mean longer baking time. I used a bundt pan, but will offer options below if you want to use some other type.

What kind of pan should I use?

The particular low carb lemon pound cake recipe I’m sharing is made in this 12-cup bundt pan. They call it a fluted tube pan.

A bundt pan is a certain type of tube pan. There are others that have flat, vertical sides, and typically larger capacity. These regular tube pans are best for a keto angel food cake, but would be too large for this keto bundt cake recipe.

If you don’t have a bundt pan, you can use two small rectangular loaf pans, two round cake pans, or a single 9×13 pan. The smaller pans will require reducing baking time, and the large 9×13 pan will require more time.

Low Carb Lemon Pound Cake Storage Instructions

Can you make it ahead?

Yes, you can! It’s one of the reasons that keto lemon pound cake with almond flour is perfect for special occasions. It’s large enough to feed a crowd, convenient to make in advance, and looks impressive without a lot of work.

How to store keto lemon pound cake

Store this keto lemon poppy seed pound cake gluten-free bundt cake in the refrigerator for up to a week. If you’re making it for an occasion, it’s best to put on the glaze fresh (the day-of), but for leftovers it’ll be fine even if the glaze is already on it.

Can you freeze low carb keto pound cake?

Yes, you can freeze the keto friendly lemon pound cake for 2-3 months. Thaw it in the fridge before serving. Reheating works okay, but the glaze will soak into the cake.

When I first tested this keto pound cake recipe, I didn’t have a specific occasion for it. So, I sliced it and stuck it in the freezer. Now, I take out a couple slices at a time, put them in the fridge, and have a yummy breakfast to enjoy with my bulletproof coffee in the morning.

Why does the cake use lemon flavoring instead of zest and juice?

I only had 2/3 c of sour cream so amended with a little Two Good vanilla yogurt. It came out beautifully. Delicious and easy. I didn’t need to cook it the extra 20 minutes.
