Ingredients
2 cups (250g) all-purpose flour Forms the base of the bread, providing structure and a soft texture.
1 teaspoon baking soda Helps the bread rise evenly for a light and fluffy result.
1 teaspoon baking powder Works with baking soda to add lift and prevent density.
1/2 teaspoon salt Balances the sweetness and enhances the overall flavor profile.
1/2 cup (8 tablespoons; 113g) unsalted butter, softened to room temperature Adds richness and moisture, making the bread tender.
2/3 cup (135g) granulated sugar Provides the primary sweetness and helps create a golden crust.
1/4 cup (50g) packed light or dark brown sugar Contributes a deeper, caramel-like sweetness for added depth.
2 large eggs, at room temperature Bind the ingredients together and add moisture for a cohesive batter.
1/2 cup (120g) sour cream, at room temperature Keeps the bread moist and adds a slight tanginess.
1 and 1/2 teaspoons pure vanilla extract Infuses a warm, aromatic flavor that ties everything together.
1/3 cup (80ml) milk, at room temperature Thins the batter for easy mixing and contributes to the bread’s tenderness.
1 and 1/2 cups (210g) fresh blueberries Burst with juicy flavor and provide natural sweetness and nutrition.
2 tablespoons blueberry jam Adds extra berry intensity and a swirl for visual appeal.
1/4 cup all-purpose flour Creates a crunchy topping when mixed with other elements.
2 tablespoons brown sugar Sweetens the topping and adds a nutty note.
1/4 teaspoon ground cinnamon Infuses a warm spice that complements the blueberries.
2 tablespoons melted unsalted butter Binds the topping ingredients for a perfect crumble.
Instructions
1-First Step: Start by preheating your oven to 350°F (177°C) and position the rack in the lower third for even baking. Grease a 9×5-inch loaf pan with non-stick spray to ensure the bread releases easily. This initial setup takes about 5 minutes and sets the stage for success.
2-Second Step: In a large bowl, whisk together 2 cups (250g) all-purpose flour, 1 teaspoon baking soda, 1 teaspoon baking powder, and 1/2 teaspoon salt. This dry mix forms the foundation, so mix until well combined, taking about 1 minute.
3-Third Step: In a separate bowl, beat 1/2 cup (113g) softened unsalted butter, 2/3 cup (135g) granulated sugar, and 1/4 cup (50g) packed brown sugar on high speed until creamy, which takes around 2 minutes. This creates a smooth base for the wet ingredients.
4-Fourth Step: Add 2 large eggs, one at a time, beating well after each addition to incorporate air and ensure even texture. Then, beat in 1/2 cup (120g) sour cream and 1 and 1/2 teaspoons pure vanilla extract until fully combined, about 1 minute more.
5-Fifth Step: With the mixer on low speed, gradually add the dry ingredients from the first bowl to the wet mixture, alternating with 1/3 cup (80ml) milk. Mix just until combined, avoiding over-mixing to prevent tough bread; this should take 30-45 seconds.
6-Sixth Step: Gently fold in 1 and 1/2 cups (210g) fresh blueberries by hand to keep them intact and distribute them evenly. If using the optional 2 tablespoons blueberry jam, swirl it into the batter now for added flavor.
7-Seventh Step: Spoon the batter into the prepared loaf pan, smoothing the top. If desired, sprinkle on the optional crumb topping made from 1/4 cup all-purpose flour, 2 tablespoons brown sugar, 1/4 teaspoon ground cinnamon, and 2 tablespoons melted unsalted butter.
8-Eighth Step: Bake the bread for 60-65 minutes, covering loosely with aluminum foil after 30 minutes to avoid over-browning. Check doneness by inserting a toothpick into the center; it should come out clean.
9-Ninth Step: Once baked, remove the bread from the oven and let it cool completely in the pan on a wire rack, which takes about 1-2 hours. This final step ensures the bread sets properly for easy slicing. For more ideas on complementary recipes, visit our Fresh Smoothie Guide to pair your bread with a healthy drink.

🫐 Use fresh blueberries for best results. If using frozen, keep them frozen, add 2 extra tablespoons of flour, and extend the baking time.
🍽️ Substitute plain yogurt for sour cream if needed. Unsweetened applesauce or mashed banana also work as alternatives.
⏲️ Bring all refrigerated ingredients to room temperature before mixing for a more even texture and rise.
