Ingredients
For the Loaf Batter
- 1 ½ cups all-purpose flour
- 1 teaspoon baking powder
- ½ teaspoon salt
- ½ cup unsalted butter, softened
- ¾ cup granulated sugar
- 2 large eggs, room temperature
- 1 cup sourdough discard (unfed)
- 1 tablespoon lemon zest
- 2 tablespoons fresh lemon juice
- 1 teaspoon vanilla extract

How to Make Sourdough Blueberry Lemon Cream Cheese Loaf
Step 1
Preheat the oven to 350°F (175°C). Grease and line a standard 9×5-inch loaf pan with parchment paper, leaving overhang for easy removal.
Step 2
In a medium bowl, whisk together flour, baking powder, and salt. Set aside.
Step 3
In a large bowl, cream the butter and sugar until light and fluffy. Add the eggs one at a time, mixing well after each addition.
Step 4
Mix in the sourdough discard, lemon zest, lemon juice, and vanilla extract until fully combined.
Step 5
Gradually fold in the dry ingredients, mixing just until combined. Avoid overmixing to keep the loaf tender.
Step 6
Toss the blueberries with 1 tablespoon flour and gently fold them into the batter.
Step 7
In a separate bowl, beat the cream cheese, sugar, egg, and vanilla until smooth and creamy.
Step 8
Pour half of the loaf batter into the prepared pan. Spread the cream cheese mixture evenly over the batter, then top with the remaining batter.
Step 9
Use a knife or skewer to gently swirl the layers for a marbled effect.
Step 10
Bake for 55–65 minutes, or until a toothpick inserted into the center comes out clean. Tent loosely with foil if the top browns too quickly.
Step 11
Allow the loaf to cool in the pan for 15 minutes, then transfer to a wire rack to cool completely before slicing.
Tips for Perfect Results
Use room-temperature ingredients for smooth mixing and even baking. Coat the blueberries in flour to prevent sinking. Allow the loaf to cool completely so the cream cheese layer can set properly. If using frozen blueberries, do not thaw them before adding to the batter.

Glaze and Streusel Topping Variations
Lemon Glaze
For a bright, tangy finish, mix ½ cup powdered sugar with 1–2 tablespoons fresh lemon juice. Drizzle over the cooled loaf for an extra burst of lemon flavor. This glaze pairs beautifully with the cream cheese layer, highlighting the citrus notes without overpowering the blueberries.
Vanilla Glaze
Combine ½ cup powdered sugar with 1–2 tablespoons milk or cream and ½ teaspoon vanilla extract. Drizzle lightly over the top to add sweetness and a shiny finish, giving the loaf a bakery-style appearance.
Crunchy Streusel Topping
Mix ¼ cup flour, 3 tablespoons brown sugar, 3 tablespoons cold butter, and ½ teaspoon cinnamon. Sprinkle over the batter before baking for a crunchy, caramelized topping. The streusel adds texture and a warm, cinnamon flavor that complements the lemon and blueberry perfectly.
Serving Suggestions

This loaf is delicious served plain, letting the lemon, blueberry, and cream cheese flavors shine. For an extra treat, dust with powdered sugar or drizzle with a simple lemon glaze. Serve slightly warm for breakfast or at room temperature with coffee or tea for an afternoon treat.
