Ingredients
For the Cake

- 1 teaspoon baking soda
- ½ teaspoon salt
- 1 cup unsalted butter, softened
- 1½ cups granulated sugar
- 4 eggs, room temperature
- 2 teaspoons vanilla extract
- 1 cup buttermilk
- Zest of 3 lemons
- ¼ cup fresh lemon juice
- 1½ cups fresh blueberries
- 1 tablespoon flour (for blueberries)
For the Blueberry Cream Cheese Frosting
- ¾ cup unsalted butter
- 6 oz cream cheese, softened
- ¼ cup blueberry jam
- 3 cups powdered sugar
- 1 teaspoon vanilla extract
Instructions
Step 1: Prepare the Pan
Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking pan or line it with parchment paper for easy removal.
Step 2: Mix the Dry Ingredients
In a large bowl, whisk together:
- Flour
- Baking powder
- Baking soda
- Salt
Set aside.
Step 3: Cream Butter and Sugar
In another bowl, beat the butter and sugar together for 2–3 minutes until light and fluffy. This step helps create a soft cake texture.
Add the eggs one at a time, then mix in vanilla extract.
Slowly pour in the buttermilk while mixing on low speed.
Step 4: Combine Everything
Add the dry ingredients in two parts and mix gently until combined.
Stir in the lemon juice and lemon zest.
The batter will smell fresh and citrusy already!
Step 5: Add the Blueberries
Toss the blueberries with 1 tablespoon flour. This keeps them from sinking to the bottom while baking.
Carefully fold the blueberries into the batter.
Step 6: Bake
Pour the batter into the prepared pan and spread evenly.
Bake for 40–45 minutes or until a toothpick inserted in the center comes out clean.
Let the cake cool completely before frosting.
Make the Frosting
Beat the butter for 5–8 minutes until pale and fluffy.
Add the cream cheese and mix until smooth.
Mix in the blueberry jam.
Slowly add powdered sugar, then add vanilla extract.
Whip everything together until light, creamy, and fluffy.
The frosting will turn a gorgeous soft purple color naturally from the blueberry jam.
Frost and Serve
Spread the frosting generously over the cooled cake.
Top with extra blueberries or lemon zest if desired.
Slice into squares and serve.
Every bite is packed with sweet blueberries, bright lemon flavor, and creamy frosting goodness.
