This simple to make vegan lemon blueberry cake is one you can enjoy all year long, but when fresh blueberries are in season, it makes it even better!

Why you’ll love this “cake”
Okay, so I’m calling this a cake, and no it’s not your typical layer cake with frosting.
But, it’s incredibly delicious, and you’ll be happy to know that this cake is FAR more wholesome than your average version.
- For starters, this lemon blueberry cake is oil free, and uses applesauce instead.
- Rather than using refined white all-purpose flour, these are made with wholesome oat flour. (As an added bonus, that means this cake is made using naturally gluten-free flour.)
- Since there are no eggs, dairy (or oil) being used, that keeps the cake very low in fat.
- It’s naturally sweetened with a heaping cup of blueberries and some unrefined coconut sugar.
Ingredients + Substitutions
Here’s what you’ll need to make this healthy vegan lemon blueberry cake.
- Oat flour: Oat flour keeps this cake naturally gluten free, and far more wholesome compared to white plain flour. If you don’t have oat flour on hand, you can easily make some by grinding oats in a blender.
- Coconut sugar: I like using unrefined coconut sugar, but brown sugar works as well if you’re not avoiding refined sugar.
- Soy milk: Soy milk keeps this cake dairy-free, but if you have an allergy and require a soy free option, almond milk works as well. However, note that soy milk is the better option if you can have soy, as it interacts with the lemon juice best, creating vegan buttermilk.
- Lemon juice + zest: The lemon juice sits with the soy milk while you prepare the other ingredients and causes the milk to thicken and curdle. This is how you make vegan buttermilk. Plus, the juice and zest add a nice lemon flavour to the cake.
- Blueberries: It wouldn’t be a vegan blueberry lemon cake without the blueberries! Use fresh if possible for the best flavour, but frozen blueberries work in a pinch.
- Applesauce: I use unsweetened applesauce to exclude any refined sugar from my dessert. The applesauce adds moisture and acts as a binder which eliminates the need for eggs and oil. If you don’t have applesauce on hand, mashed banana also works well.
- Vanilla: Adds flavour, but stick to pure vanilla extract, and not the artificially flavoured kind.
- Baking powder + soda: Our rising agents, do not skip. Make sure your rising agents are still active for the best lift. Open products that sit in your pantry for 6+ months begin to lose their effectiveness.
Instructions
(This is a summary with step by step photos, full recipe measurements and instructions are in the recipe card below.)
Begin by adding the lemon juice and zest to a bowl with the soy milk. Set it aside to let it thicken and curdle. (photo 1)
Meanwhile, add all the dry ingredients to a medium mixing bowl and whisk to combine. (photo 2)
Pour the vegan buttermilk you just made, and all remaining wet ingredients into the bowl of dry ingredients. (photo 3)
Mix well, and then fold in ¾ of your fresh blueberries, reserving ¼ cup of them for sprinkling on top of your cake. (photo 4)
Pour the cake batter into your pan and sprinkle the remaining blueberries on top, pushing most of them down. (photo 5)
Then bake your lemon blueberry cake in your preheated oven until a toothpick inserted in the middle comes out clean. (photo 6)
Let the cake cool for at least 30 minutes in its pan before handling. Then transfer to a cooling rack to continue cooling.
Once cooled, place it on a cake plate and sprinkle with some powdered sugar, if you’d like. Alternatively, you can drizzle the cake with a lemon glaze, as I’ve done for these muffins.
NOTE: These toppings will increase the calories and sugar content, so skip them if preferred.
Slice into 10 triangles and serve with more fresh blueberries.
Equipment
Use a nine-inch cake pan, (affiliate link) or similar.
You may also use a 9-inch springform pan for easy removal.
If using a smaller pan, or a loaf pan, the cake will take a little longer to bake. So test with a toothpick to check for doneness.
I don’t recommend using a larger pan, as the cake will be too thin.
Storage
Leftovers will keep at room temperature in a sealed container or tightly wrapped in plastic wrap for 2-3 days.
If you plan to keep it longer than 2 days, I recommend refrigerating it to preserve its moisture.
You may freeze an entire cake or slices of cake in an airtight freezer-safe container for up to 3 months.
Expert Tips
- Weigh your flour for the most accurate results. If you don’t have a kitchen scale, you may spoon the flour into your measuring cup and use a knife to scrape off the excess. Do not scoop from the bag!
- Don’t skip making the vegan buttermilk. (Mixing the soy milk with lemon juice.) This enhances the dairy flavour, and makes the texture fluffier.
- Make sure your baking powder + soda are active. Open products that sit in your pantry for 6+ months begin to lose their effectiveness and rising power.

Can you use any other four?

This hasn’t been tested with another flour. Please let us know if you decide to experiment.
Sarah
Chickpea flour works better and so does date sugar vs anything “coconut” of which provides no nutrition other than calories and fat. Also, I recommend vanilla paste or powder and it elevates it to a whole new level minus the alcohol in “extract.” Once you use this you’ll never go back. This turned out delicious! Thank you!
Rosa
Sounds like you made a few changes to the recipe. So glad it worked out! Thanks for sharing your process with us.
Robin
Hi Sarah , I’d like to tweak it like you . Would you send me your amounts for the changes you made? Thanks so much.
Kim
I tried it! Very delicious 😋. I had one slice and my husband, and my 3 boys finished off the rest of it so quickly! Thank you for this healthy vegan dessert Rosa!
Rosa
Fantastic, thrilled you all enjoyed it Kim. Thanks for sharing!
Gayle
I have been looking for a fast, tasty, oil-free & gluten free cake recipe for a long time, so I was eager to try this one. While definitely tasty (in a delicate way), the cake itself was way too dense. It was still moist, however, which made it edible. I think I will give it one more try, but use a lighter flour to see.
Rosa
Glad you found the cake tasty Gayle. You’re right that it will be denser than a classic cake and this is due to the oat flour. Thanks for sharing and please let us know how it goes if you decide to experiment with another flour.
Lilli
I’m so excited to make this for my daughters 2nd birthday tomorrow!
I just ground up my oats in the vitamin and weighed them to 270. It didn’t look like much so I spooned them into leveled off cups and it’s only 2 1/4 cups… should I add more flour? Not sure what to do! Thank you!
Rosa
Hi Lilli, weight is more accurate than cup measurements so stick with the weight. Enjoy 😊
Lillian D'Vincent
Perfect!! Thank you so much!!
Kate
I made this cake substituting saskatoons from my yard for the blueberries. As I didn’t have any coconut sugar, I replaced it with the suggested brown sugar alternative. This cake was wonderfully lemony and the saskatoons added their unique pop of flavour. Thanks for this recipe.
Rosa
💗💗
Kate
While picking saskatoons, yesterday, from the tree in my back yard, I was thinking, “I need more recipes to use these in.” When I came into the house, there was your email with this recipe. I love most things lemon, and often substitute saskatoons for blueberries. Decision made, I would make this cake. I find I usually have to add more zest to most recipes to give them enough lemon flavour for my taste. I was impressed that your recipe called for 1 Tablespoon of zest; no need to increase that! I even happened to have oat flour in the freezer that needed using, however, I did not have coconut sugar so I used the recommended brown sugar alternative. This was a very easy cake to put together, and I used my freshly picked saskatoons rather than blueberries. The result was delicious and has received a seal of approval from my omnivore partner. I will be dropping some off to my gluten intolerant neighbour, a good thing for both of us as otherwise it will be difficult for me not to eat all the cake myself!!! (Confessions of a cake-aholic!)
Thanks for another excellent recipe.
Rosa
Hi Kate, thank you so much for taking the time to leave this glowing review. 🙂 I’m absolutely thrilled you both enjoyed the cake.
Beverly
This was so good!! I had 2 slices immediately and trying so hard not to go back for more right now. Thanks for this delicious and healthy blueberry lemon cake Rosa!
Rosa
Thrilled you enjoyed it Beverly. Thanks so much for the review. 🙂
Kaye Dill
Hi,
This looks delicious. Can I use another kind of milk – I’m not suppose to have soy. Thanks
Kaye
Rosa
Yup, if you take a peek at our ingredients + substitutions section, there is a blurb about using almond milk instead. Enjoy! 🙂
Siddika
Hi Rosa,
This recipe sounds delicious, and I plan to make it!Thanks!
I have a question: do you or anyone you know use erythritol in
baking? If you do, what has been your experience.
With gratitude for your recipes,
Siddika
Rosa
Hi Siddika, I haven’t used erythritol before so unfortunately, I cannot speak to using it as a sub. Let me know if you give it a try. 🙂
