Step 1: Preheat and Prep
Preheat your oven to 350°F (175°C). Grease and flour a 9×5-inch loaf pan, or line with parchment paper leaving overhang on the long sides for easy removal.
tep 2: Make the Streusel
In a small bowl, combine flour, brown sugar, and cinnamon. Add cold butter cubes and cut in using a pastry blender, two forks, or your fingertips until the mixture resembles coarse crumbs. Set aside in the refrigerator.
Step 3: Make the Cream Cheese Swirl
In a small bowl, beat together cream cheese, sugar, egg yolk, and vanilla until smooth. Set aside.
Step 4: Prepare the Blueberries
In a small bowl, toss the blueberries with 1 tablespoon flour until coated. This simple step prevents them from sinking to the bottom of the loaf.
