1-Getting your blueberry muffin bread just right: starts with a few basic steps that anyone can follow, even if you’re new to baking. Begin by preheating your oven to 350°F (177°C) and positioning the rack in the lower third for even baking. Grease a 9×5-inch loaf pan or coat it with nonstick spray to prevent sticking and ensure easy removal.

2-In a large bowl, whisk together the flour, baking soda, baking powder, and salt to combine the dry ingredients evenly. This step sets the foundation for your blueberry muffin bread’s soft texture. Using a mixer, beat the softened butter with granulated and brown sugar on high speed until creamy, about 2 minutes, then add eggs one at a time on medium speed, beating after each for smooth incorporation.

3-Next, beat in the sour cream and vanilla extract until fully combined, creating a rich base. On low speed, add the dry ingredients and milk, mixing just until combined and no flour pockets remain to keep the bread tender. Gently fold in the fresh blueberries to distribute them without crushing, preserving that burst of sweet flavor.

4-Baking and Cooling Tips: Pour the batter into the prepared pan, and if you like, swirl in blueberry jam or sprinkle on the optional crumble topping for added flair. Bake for 60-65 minutes, covering loosely with foil after 30 minutes to avoid over-browning, and test doneness with a toothpick it should come out clean. Let the bread cool completely in the pan on a wire rack before slicing, which takes about 3 hours total including baking and cooling time.
