Blueberry Lemonade Buttermilk Cake

Blueberry Lemonade Buttermilk Cake is a bright, tender, and tangy dessert that bursts with juicy blueberries and zesty lemon in every bite. The buttermilk gives it a soft, moist crumb, while the lemon glaze adds just the right sweet-tart finish. It’s the kind of cake I love to bake when I want something fruity, fresh, and perfect for any season.

Why You’ll Love This Recipe

I love how this cake brings together the classic pairing of blueberries and lemon in such a soft, luscious way. The buttermilk makes it extra moist, while the lemon zest and juice give it a sunny, citrusy kick. It’s easy to make, great for brunch or dessert, and it keeps beautifully—if I don’t eat it all first!

ingredients

(Here’s a tip: Check out the full list of ingredients and measurements in the recipe card below.)

  • All-purpose flour

  • Baking powder

  • Baking soda

  • Salt

  • Unsalted butter, softened

  • Granulated sugar

  • Eggs

  • Buttermilk

  • Fresh lemon juice

  • Lemon zest

  • Vanilla extract

  • Fresh or frozen blueberries (if frozen, I don’t thaw them)

For the glaze:

  • Powdered sugar

  • Fresh lemon juice

  • Lemon zest (optional)

directions

  1. I preheat the oven to 350°F (175°C) and grease and flour a 9-inch round or loaf cake pan.

  2. In a bowl, I whisk together the flour, baking powder, baking soda, and salt.

  3. In a separate large bowl, I cream the butter and sugar until light and fluffy.

  4. I beat in the eggs one at a time, then mix in the lemon juice, zest, and vanilla extract.

  5. I add the dry ingredients in three parts, alternating with the buttermilk, mixing just until combined.

  6. I gently fold in the blueberries, tossing them first in a little flour to help prevent sinking.

  7. I pour the batter into the prepared pan and smooth the top.

  8. I bake for 45–55 minutes, or until a toothpick inserted in the center comes out clean.

  9. While the cake cools slightly, I whisk together the glaze ingredients until smooth.

  10. I drizzle the glaze over the warm or cooled cake and let it set before slicing.

Servings and timing

This recipe serves 8–10.
Prep time: 15 minutes
Bake time: 45–55 minutes
Cool time: 30 minutes
Total time: approximately 1 hour 30 minutes

Variations

Sometimes I add a handful of chopped strawberries for extra color and flavor. I’ve made it in muffin form for individual servings, or doubled the recipe for a layered version with lemon curd between the layers. When I want extra texture, I sprinkle a bit of coarse sugar or sliced almonds on top before baking.

storage/reheating

I store the cake at room temperature in an airtight container for up to 3 days, or refrigerate it for up to 5 days. To reheat, I warm individual slices in the microwave for 10–15 seconds. It also freezes well—I wrap it tightly in plastic and foil, then thaw at room temperature before serving.

FAQs

Can I use frozen blueberries?

Yes, I often use frozen blueberries straight from the freezer. I toss them in a little flour before adding to the batter to help keep them from sinking and turning the batter blue.

What can I use instead of buttermilk?

I make a quick substitute by mixing 1 tablespoon of lemon juice or vinegar with 1 cup of milk and letting it sit for 5 minutes. It works just as well in this recipe.

Does this cake need to be refrigerated?

Only if I want to keep it for more than a few days. Otherwise, it stays fresh at room temperature in a covered container.

Can I make this into cupcakes?

Yes! I divide the batter into cupcake liners and bake at 350°F for about 20–25 minutes. They turn out soft and fluffy with a perfect dome.

How do I keep the blueberries from sinking?

Tossing them in a little flour before folding into the batter helps distribute them evenly and keeps them suspended throughout the cake.

Conclusion

Blueberry Lemonade Buttermilk Cake is a soft, citrusy treat I always come back to when I want something light and refreshing with a sweet finish. It’s packed with juicy blueberries, brightened by lemon, and made ultra-tender thanks to buttermilk. Whether I’m baking it for brunch, a spring picnic, or just because, it’s always a sweet success.
