Ingredients
Method
Prepare Cream Cheese Filling
- Beat softened cream cheese with 1/4 cup sugar until smooth. Mix in the egg yolk and 1/2 teaspoon vanilla, then set aside.
Make Crumble (Optional)
- Whisk together 1/2 cup flour, 1/4 cup sugar, brown sugar, and cinnamon. Cut in cold butter until coarse crumbs form; set aside.
Prepare Batter
- Preheat the oven to 350°F (175°C). Grease and flour a 9x5-inch loaf pan.
- In a medium bowl, whisk together 3 cups flour, baking soda, and salt until blended.
- In a large bowl, cream 1 cup sugar with 1/2 cup softened butter until light and fluffy. Beat in the eggs, one at a time, then stir in 1 teaspoon vanilla.
- Gradually add dry ingredients to the wet, alternating with 1 cup sour cream, beginning and ending with dry. Mix just until combined.
- Gently fold in 1 cup fresh blueberries.
Assemble and Bake
- Pour half the batter into the prepared pan. Spoon the cream cheese filling down the center. Cover with remaining batter and smooth the top.
- Sprinkle crumble and extra blueberries on top if using.
- Bake for 55–65 minutes or until the top is golden and a skewer comes out clean.
- Let cool in the pan for 10–15 minutes, then transfer to a rack to cool completely before slicing.
Notes
Use fresh blueberries for best texture. Room-temperature eggs mix more evenly. Consider pairing with yogurt and granola for a complete brunch.
