1-Creating Blueberry Muffin Bread is a fun and rewarding process that anyone can master. Start by preheating your oven to 350°F and placing the rack in the lower third to ensure even baking. Grease your loaf pan or use nonstick spray for easy release later.

2-Next, in a bowl, whisk together 2 cups all-purpose flour, 1 teaspoon baking soda, 1 teaspoon baking powder, and 1/2 teaspoon salt until well mixed. This step helps distribute the leavening agents evenly for a nice rise. In another bowl, beat 1/2 cup unsalted butter with 2/3 cup granulated sugar and 1/4 cup packed brown sugar on high speed until smooth and creamy.

3-Add 2 large eggs, one at a time, beating after each addition. Then, mix in 1/2 cup sour cream and 1 1/2 teaspoons pure vanilla extract for extra moisture and flavor. Slowly add the dry ingredients to the wet mixture along with 1/3 cup milk, mixing on low speed until just combined without any flour pockets. Gently fold in 1 1/2 cups fresh blueberries to keep them whole and distribute them evenly.

4-Spoon and Bake the Batter Pour the batter into your prepared pan and smooth the top for even baking. If you want, swirl in 2 tablespoons of blueberry jam for added fruitiness. Sprinkle on the crumble topping if you’re using it made from flour, brown sugar, cinnamon, and melted butter for a crunchy finish.

5-Bake for 60-65 minutes, covering loosely with foil after 30 minutes to avoid over-browning. Check for doneness with a toothpick; it should come out clean. Let the bread cool completely on a wire rack before slicing, which takes about an hour, making the total time around 3 hours including prep and cooling.

6-Remember, fresh blueberries work best, but if you use frozen ones, add 2 tablespoons extra flour and bake a bit longer without thawing. Toss the berries in flour first to stop them from sinking. The total preparation time is about 15 minutes, followed by baking and cooling.
