Ingredients
– 2 cups (250g) all-purpose flour
– 1 teaspoon baking soda
– 1 teaspoon baking powder
– 1/2 teaspoon salt
– 1/2 cup (8 Tbsp, 113g) unsalted butter, softened
– 2/3 cup (135g) granulated sugar
– 1/4 cup (50g) packed light or dark brown sugar
– 2 large eggs, at room temperature
– 1/2 cup (120g) sour cream, at room temperature (can substitute plain yogurt)
– 1 1/2 teaspoons pure vanilla extract
– 1/3 cup (80ml) milk, at room temperature (any dairy or nondairy milk)
– 1 1/2 cups (210g) fresh blueberries (fresh preferred; if using frozen, do not thaw and add 2 tablespoons more flour, extending bake time accordingly)
– 2 tablespoons blueberry jam swirl
– 1/4 cup all-purpose flour for crumble topping
– 2 tablespoons brown sugar for crumble topping
– 1/4 teaspoon ground cinnamon for crumble topping
– 2 tablespoons melted unsalted butter for crumble topping
Instructions
1-Preheat oven: Preheat oven to 350Β°F (177Β°C). Position an oven rack in the lower third, and grease or spray a 9Γ5-inch loaf pan.
2-Mix dry ingredients: In a bowl, whisk together the flour, baking soda, baking powder, and salt.
3-Beat wet ingredients: Beat the butter, granulated sugar, and brown sugar at high speed until creamy (about 2 minutes). Add eggs one at a time, beating well after each addition.
4-Add sour cream and vanilla: Mix in sour cream and vanilla extract until combined.
5-Combine dry and wet ingredients: On low speed, add the dry ingredients and milk; beat until no flour pockets remain.
6-Fold in blueberries: Gently fold in the blueberries. Toss them in a tablespoon of flour first to prevent sinking.
7-Prepare for baking: Spoon batter into the prepared pan. Swirl in jam if using, or sprinkle crumble topping over the loaf.
8-Bake the loaf: Bake for 60-65 minutes, loosely covering with foil after 30 minutes to prevent excessive browning. Test doneness with a toothpick; it should come out clean.
9-Cool the bread: Cool completely in the pan on a wire rack.
Notes
π§ Use room temperature ingredients to ensure even mixing.
π« Toss blueberries in flour before folding to prevent sinking.
π₯ Sour cream adds moisture and activates baking soda; plain yogurt can be substituted.
