Throughout our childhood, my brother and I celebrated nearly every one of our birthdays with a pool party since we were both born during the summer. Back then, we belonged to a small pool club in a quiet neighborhood, which was the perfect place for a children’s birthday party.
We kept those parties small, only inviting a handful of our closest friends, but we still loved every minute of the celebrations. For hours, we practiced cannonball jumps in the deep end and underwater somersaults in the shallow side, and we usually pulled out a set of neon plastic diving rings to play with, too.
Eventually, Mom called us all out of the water, and we eagerly obliged… Because that meant it was time for cake!
Two weeks earlier, Mom had taken us to the grocery store, and she let us slowly pore through the bakery’s big binder of birthday cake options. A beautiful color photograph of each confection filled every page, but after an eternity of flipping through the binder, I often picked out a chocolate cake with a Disney theme, while my brother generally chose a vanilla cake with race cars instead.
At our parties, Mom carefully opened the big bakery box to reveal the gorgeous cake we had ordered, which came with “Happy birthday!” scripted across in icing letters. After blowing out the candles, I always wanted the piece with my name on it… Or at least the slice with the most frosting!
Although I still love chocolate cake, my brother eventually gravitated towards lemon instead of vanilla, so I had him in mind when I baked this Healthy Lemon Bundt Cake! It’s really moist and full of bright citrus flavor, just the way my brother likes his lemon cakes, but unlike the bakery birthday cakes of our childhood… This one has no refined flour or sugar and only 122 calories!
I can’t wait to bake it again for his birthday in August! ♡
Let’s go over how to make this healthy lemon bundt cake—entirely from scratch!
You’ll start with white whole wheat flour (like this!). Yes, such a thing actually exists… And it’s not just a combination of white (aka all-purpose) flour and whole wheat flour!
Instead, white whole wheat flour is made by finely grinding a special type of soft white wheat (hence the name!), whereas regular whole wheat flour comes from a heartier variety of red wheat. This gives white whole wheat flour the same health benefits (like extra fiber!) as regular whole wheat flour, but it also has a lighter taste and texture—which lets the moist texture and lemon flavor truly shine in this healthy bundt cake!
Hint: The difference between white whole wheat flour and regular whole wheat flour is similar to the difference between red and green grapes. They both have the same nutrition benefits—just a different color and slightly different flavor!
You’ll mix lots of freshly grated lemon zest into the flour. (The lemon juice comes later!) The zest actually has a much stronger citrus taste than the juice, so it provides the majority of the lemon flavor. I’ve tested this healthy lemon bundt cake multiple times, and you need 4 full tablespoons of zest to get the best and brightest flavor. Don’t skimp!
You also need both baking powder and baking soda for this healthy lemon bundt cake. Although some recipes just use baking powder, the baking soda helps this cake rise just as much—if not more! That’s because the baking soda is a strong base, so it reacts with the lemon juice (a strong acid!) to make your lemon cake rise… And it also helps with the tender texture.
I love nerdy baking science like that! 🤓
With just 1 tablespoon of butter (or coconut oil!), as compared to traditional bundt cake recipes with ½ to 1 full cup (yikes!)… This low-calorie lemon bundt cake gets the rest of its tender texture from one of my favorite healthy baking ingredients. Do you know what it is?
That’s right—it’s Greek yogurt! (You’re so smart!) Greek yogurt adds the same moisture to your lemon cake batter as extra butter or oil but for a fraction of the calories. It also gives your cake a big protein boost!
You’ll skip the refined sugar and sweeten your healthy lemon cake with another one of my favorite ingredients: vanilla stevia. Stevia is a plant-based, no-calorie sweetener that contains nothing refined or artificial (aka it’s clean-eating friendly!). It’s also highly concentrated. You just need 5 ½ teaspoons to sweeten the entire cake… Instead of 2 ¼ cups of granulated sugar! (That definitely helps keep this lemon cake low calorie! 😉)
This is the vanilla stevia that I use because I love its warm flavor and don’t notice any strange aftertaste like with some other stevia products. Although you can find it at many health-oriented grocery stores, I buy mine online here because that’s the cheapest price I’ve found. (And you’ll use it in all of these recipes of mine, too!)
Now it’s time for the lemon juice! If at all possible, I highly recommend using Meyer lemons. They have a brighter, slightly sweeter flavor than regular ol’ lemons, which makes them perfect for baking. I actually want to plant a Meyer lemon tree in my backyard—I love them that much!
Before you spread your healthy lemon cake batter into your bundt pan, remember to generously coat your bundt cake pan with cooking spray. If you have cooking spray with flour, that’s even better! Bundt cake pans have lots more nooks and crannies than traditional round cake pans, so it’s much easier for the batter to get stuck… Which means your healthy bundt cake won’t want to slide out of the pan when you invert it. If you’re generous with the cooking spray, your bundt cake should pop right out of the pan!
One last thing! Once your healthy lemon cake has fully cooled, it’s time to drizzle a little glaze on top! It’s super simple to make: just stir together confectioners style erythritol (like this!) and lemon juice in a small bowl, transfer that to a zip-topped bag, and snip off a tiny piece of one corner to drizzle it all over your bundt cake.
Lemon bundt cake perfection! It’s truly the best lemon cake I’ve ever had! 👌🏻 And when you make your own, remember to snap a picture and share it on Instagram using #amyshealthybaking and tagging @amyshealthybaking IN the photo itself! (That guarantees I’ll see your picture! 😊) I’d love to see your healthy lemon bundt cake!

- for the cake
- 3 ¾ cups (330g) white whole wheat flour or gluten-free* flour (measured like this)
- 2 ¼ tsp baking powder
- 1 ½ tsp baking soda
- ½ tsp salt
- 4 tbsp (20g) lemon zest (about 3 extra-large)
- 1 tbsp (14g) unsalted butter or coconut oil, melted and cooled slightly
- 4 large egg whites, room temperature
- 4 tsp vanilla extract
- 5 ½ tsp vanilla stevia
- ¾ cup (180g) plain nonfat Greek yogurt
- ¾ cup (210mL) freshly squeezed lemon juice (about 3 extra-large)
- 1 ¼ cups (300mL) nonfat milk
- for the drizzle
- 3 tbsp (45g) confectioners’ style erythritol
- 2 ½ - 2 ¾ tsp freshly squeezed lemon juice
- Preheat the oven to 350°F, and generously coat a 12-cup bundt pan with nonstick cooking spray or nonstick cooking spray with flour.
- To prepare the cake, whisk together the flour, baking powder, baking soda, and salt in a medium bowl. Once thoroughly combined, whisk in the lemon zest. In a separate bowl, whisk together the butter, egg whites, vanilla extract, and stevia. Stir in the Greek yogurt, mixing until no large lumps remain. Stir in the lemon juice and ¼ cup of milk. Alternate between adding the flour mixture and milk, beginning and ending with the flour mixture, and stirring just until incorporated. (For best results, add the flour mixture in 3 equal parts.)
- Spread the batter into the prepared pan. Bake at 350°F for 55-65 minutes or until the top feels firm to the touch and a toothpick inserted into the center comes out clean. Cool in the pan for 10 minutes before transferring the cake to a wire rack to cool completely.
- Once the cake has completely cooled to room temperature and just before serving, prepare the drizzle. Stir together the erythritol and lemon juice in a small bowl. Transfer the mixture to a zip-topped plastic bag, cut off a tiny piece of one corner, and drizzle over the cooled cake.
Whole wheat pastry flour or all-purpose flour may be substituted in place of the white whole wheat flour. Regular whole wheat flour may be substituted in a pinch, although the cake will be less tender and have a distinct wheat-y flavor.
It’s extremely important to measure the flour correctly, using this method or a kitchen scale. (← That’s the one I own!) Too much flour will dry out your cake and give it a crumbly texture, instead of having it turn out moist and tender!
If you can find Meyer lemons, I highly recommend those! They have a brighter and slightly sweeter flavor, and they’re the best kind of lemons for baking (in my opinion!). Use lemons that are purely yellow without any green spots. Make sure to use the full amount of zest because that’s what provides the majority of the citrus flavor.
The cake requires 4 full egg whites. The whites contain the majority of the protein in eggs, and that protein is required to ensure the cake maintains its shape and texture while cooling. Without all 4 egg whites, the cake will collapse while cooling and turn out much denser.
I do not recommend substituting for the vanilla stevia, if at all possible. (It’s one of my favorite ingredients, and you’ll use it in all of these recipes of mine, too!) I buy mine online here because that's the best price I've found.
However, if you really prefer to omit the vanilla stevia from the cake, substitute 2 ¼ cups (432g) granulated sugar and reduce the milk to 2 tablespoons (30mL), but the cake will no longer be clean-eating friendly. You may substitute 2 ¼ cups (432g) coconut sugar and reduce the milk to 2 tablespoons (30mL) to keep the cake clean eating friendly, but it will be much darker in color. The baking time may vary with either of those substitutions as well. Do not substitute honey, maple syrup, or agave because the cake batter will be much too liquidy with any of those.
Any milk may be substituted in place of the nonfat milk.
Do not use an electric mixer to mix up the batter. This will result in a dense or tough cake. Use a whisk where instructed, and use a fork for everything else.
Make sure you coat your bundt pan really well with cooking spray! (This is the bundt pan that I use!) With so many nooks and crannies, compared to traditional round or rectangular cake pans, the batter has more chances to stick to the sides, so a generous coating of cooking spray will ensure your bundt cake slides right out of the pan.
This is the confectioners' style erythritol that I use. Regular confectioners’ style (powdered) sugar may be substituted for the confectioners’ style erythritol in the drizzle. Regular powdered sugar is much more absorbent, so start with just 1 teaspoon of lemon juice.
For more drizzle (and a sweeter cake!), double the drizzle.
If you have a 6-cup bundt pan, you can make a half-recipe and bake at 350°F for 50-60 minutes instead.

I love the way you think, Liz! 🙂
How do you recommend adapting this recipe if baking at high altitude???
I really appreciate your interest in my recipe, Marilyn! Other readers have reported that they don’t need to do anything to my recipes when baking at high altitude. (In fact, when they tried the common “high altitude” suggestions, the recipes turned out much worse!) I’d love to hear what you think if you try this cake! 🙂
So excited to see a Lemon Bundt Cake recipe without refined flour or sugars! I’m absolutely in love with the beautiful pictures you took of it, and I’ll definitely be adding this recipe to my collection! Did you use any photo editing apps to make the cake look that good? I appreciate that you added the Weight Watcher’s points with the nutrition facts!
Thanks so much for your kind words, Denise! I can’t wait to hear what you think of this cake! 🙂 (And I use Lightroom for photo editing!)
Is that 122 cal per slice or for the whole cake?
I really appreciate your interest in my recipe, Mads! The full nutrition information (which includes the answer to your question!) is directly beneath the recipe. It can be easy to miss! 😉 I can’t wait to hear what you think of this bundt cake if you try it!
I have Spenda Baturals stevia, not vanilla flavored. Rather than buy new, can I use and add vanilla?
I really think recipe looks good and would like to try.
I really appreciate your interest in my recipe, Amy! What’s the exact Splenda Naturals stevia product that you have? The packets, the jar, or the granulated type? None of those are as concentrated as the vanilla stevia that I use, so you’ll have to add a lot more and make modifications to the other ingredients as well. Just something to keep in mind! 🙂 I’m happy to help you figure out what those modifications are — I just need to know the exact format of Splenda Naturals stevia that you have!
Thanks so much! I have the jar. The conversion chart says 1 tsp sugar = 1/2 tsp. splenda naturals. 1 cup sugar = 1/2 cup splenda. I haven’t baked much with artificial sweeteners.
Thanks for the information, Amy! Super helpful. 🙂 You’d need to use 1 cup + 2 tablespoons of your Splenda Naturals stevia jar product. Then reduce the milk to ¾ cup to compensate for the added volume. You shouldn’t need to add any extra vanilla — the vanilla flavor isn’t very strong in the liquid vanilla stevia that I use. I can’t wait to hear what you think of this bundt cake!
