Lemon Blueberry Buttermilk Cake
If you’re looking for a cake that’s bright, buttery, and packed with juicy blueberries, this Lemon Blueberry Buttermilk Cake is for you.

Fresh lemon zest adds a wonderful citrus aroma, while buttermilk creates a soft, moist crumb that stays tender for days. Every slice is filled with bursts of sweet blueberries, making it perfect for breakfast, brunch, afternoon coffee, or dessert.
One of my favorite things about this cake is its simplicity. There’s no frosting to make and no decorating required. The cake is beautiful on its own and delivers the kind of fresh, homemade flavor that keeps everyone coming back for another slice.

What Makes Buttermilk Important?
Buttermilk plays an important role in creating a soft, tender cake. Its natural acidity helps break down gluten strands, resulting in a finer crumb and a lighter texture.
It also reacts with baking soda to help the cake rise, giving it a delicate and airy structure. In addition to improving texture, buttermilk adds moisture and a subtle tangy flavor that balances the sweetness of the cake and enhances the fresh lemon flavor.
If you’ve ever wondered why some cakes stay moist for days while others become dry quickly, buttermilk is often one of the reasons.
Tips for Success
- Toss blueberries in a little flour before folding them into the batter.
- Use fresh lemon zest for the best flavor.
- Do not overmix the batter.
- Allow the cake to cool completely before slicing.
Variations
- Add a simple lemon glaze.
- Use raspberries instead of blueberries.
- Make it as muffins.
- Add poppy seeds.

This cake will remind you of pound cake except it’s lighter, more succulent, and aromatic. if you are craving more and maybe cookies, check the recipes below:

Growing up, I didn’t know about buttermilk as it’s not a common ingredient in Japan. After I tried it in pancake recipe, I got hooked! It tastes so much better! Now I need to try it in the cake too! Your blueberry+ lemon cake look so delicious!
Thanks Nami, I’m sure you’ll love it 🙂
Thank you so much Muna! So excited to try this cake! Do you think yogurt would be a good substitute for buttermilk? I don’t think I can get buttermilk here in Japan 🙁
Hi Felice, you can make buttermilk by adding one and 1/2 tablespoon of lemon juice to 3/4 cup milk, mix well and keep aside for 5 minutes, and you have your buttermilk ready 🙂
I can eat blueberries or really any fruit for that matter as a snack or even dessert, but I’d rather this cake 🙂
Hey Laura, thanks for stopping by! I hope you give this cake a try, I’m sure you’ll like it.

I don’t have fresh blueberries with me but i do have thick blackberry crush.can i make this cake using it,if yes then how the quanity of ingredients change as per that?
Hi Shalini, Thanks for stopping by. I think the whole recipe will change if you add any other type of liquid to it. Use blueberry or other type of fruit like dates.
I don’t have fresh blueberries but blueberry crush..can i use it to make a cake like this by changing the proportions a bit
Hi can I use frozen blueberries?
You can use frozen blueberries, but make sure to add them to the batter while they are frozen and do not over mix the batter otherwise the blueberries will bleed!
