I love a cake that feels like summer. My Lemon Blueberry Cake is bright, soft and full of berries. I make it when I want a cake that still feels light.
Dad James first taught me to fold berries in gently. I think of him every time I scoop the batter into the pan.
Gathering Your Ingredients
For the Lemon Blueberry Cake
- 3 cups cake flour (360 grams)
- 2 teaspoons baking powder
- 1/2 teaspoon baking soda
- 1/2 teaspoon salt
- 3/4 cup buttermilk (180 ml) (room temperature)
- 1/3 cup lemon juice (80 ml) (freshly squeezed)
- 1 cup unsalted butter (226 grams) (softened to room temperature)
- 1 3/4 cups granulated sugar (350 grams)
- 2 tablespoons lemon zest
- 2 teaspoons vanilla extract
- 4 large eggs (room temperature)
- 2 cups blueberries (I recommend using fresh)
- 2 teaspoons cake flour (or all-purpose flour)
For the Frosting (Option 1 / Smaller Batch)
- 1/2 cup unsalted butter (112 grams) (softened)
- 8 oz brick-style cream cheese (226 grams)
- 1 teaspoon lemon juice (freshly squeezed)
- 3 – 4 cups powdered sugar (330-440 grams) (sifted)
- 1 tablespoon whipping cream (as needed)
For the Frosting (Option 2 / Larger Batch)
- 3/4 cup unsalted butter (168 grams) (softened)
- 12 ounces brick-style cream cheese (340 grams) (full fat)
- 1 1/2 teaspoons lemon juice (freshly squeezed)
- 4 1/2 – 5 1/2 cups powdered sugar (495 – 605 grams) (sifted)
- 1-2 tablespoon whipping cream (as needed)
The Tools That Help
I keep tools simple: a mixer, bowls, spatula, spatula for folding, measuring cups, a sifter, and a 9×13 pan or two 8-inch round pans. I also use parchment paper and a toothpick. If you like blueberry snacks, I have a small treat that pairs well called Blueberry Cheesecake Protein Bites 2.
The Step-by-Step Process
- Preheat the oven to 350F (180C) and grease and flour your pan(s).
- For layer cakes, line pans with parchment rounds and grease the sides.
- Sift together the flour, baking powder, baking soda and salt in a medium bowl.
- Whisk the buttermilk and fresh lemon juice in a small bowl and set aside.
- Beat the butter, sugar and lemon zest in a large bowl until light and fluffy.
- Add the vanilla and beat in the eggs one at a time, scraping the bowl after each.
- On low speed, add about one third of the flour mix to the butter mix.
- Add about half of the milk-lemon mix and scrape the bowl.
- Repeat: add one third of flour, then the rest of the milk mix, then the last third of flour.
- Toss the blueberries with 2 teaspoons of flour and fold them gently into the batter.
- Pour the batter into the prepared pan(s) and smooth the top.
- Bake 30 to 35 minutes for a 9×13 pan, or 25 to 30 minutes for layer pans.
- The cake is done when the top looks set and a toothpick comes out clean.
- Let the cake cool in the pan until it reaches room temperature before removing.
- For the basic cream cheese frosting, beat 1/2 cup butter and 8 oz cream cheese until smooth.
- Add 1 teaspoon lemon juice, then beat in 3 to 4 cups powdered sugar until smooth, adding 1 tablespoon whipping cream if needed.
- For a larger batch, beat 3/4 cup butter with 12 oz cream cheese, add 1 1/2 teaspoons lemon juice, and slowly add 4 1/2 to 5 1/2 cups powdered sugar, using 1 to 2 tablespoons whipping cream to reach spreadable texture.
- Chill the frosting briefly if it seems soft, then spread it over the cooled cake or between the layers.
- Decorate with extra lemon zest and fresh blueberries if you like.

Lighter, Healthier Touches
I swap half the butter for Greek yogurt to cut fat and keep the cake moist. I also use less sugar in the batter and a lighter frosting with more cream cheese than butter. Fresh berries work better than frozen for texture.
Perfect Pairings
I serve this cake with a simple pot of tea or cold milk. For a bright contrast, try a tart sorbet. For a snack plate, pair a slice with my Blueberry Cheesecake Protein Bites for a small bite beside dessert.
Common Stumbles to Avoid
Do not overmix once you add the flour. Overmixing makes a dense cake. Make sure the eggs and butter are at room temperature for a smooth batter. Toss the berries in flour to stop them from sinking.
Storing Your Creation
Keep the frosted cake in the fridge for up to 4 days in an airtight container. You can freeze slices wrapped well for up to 2 months. Thaw in the fridge overnight before serving.
A Final Warm Word
I bake this cake for family and friends because it feels like sunshine on a plate. I hope you make it and share it with someone you love.
Answering Your Questions
Can I use frozen blueberries in Lemon Blueberry Cake?
Yes. I use frozen berries when fresh are not available. Do not thaw them first. Toss them in the flour and fold in frozen so they keep their shape.
How do I know when the Lemon Blueberry Cake is done?
The top will look set and slightly springy. A toothpick inserted in the center should come out clean or with a few crumbs. If it has wet batter, bake a few more minutes.
Can I make the Lemon Blueberry Cake ahead of time?
Yes. You can bake the cake a day ahead and store it in the fridge, then frost it the next day. For more time, freeze unfrosted layers and thaw in the fridge before frosting.
