Creating your Blueberry and Lemon Loaf is straightforward if you follow these simple steps:

1. Preheat the Oven: Preheat your oven to 350°F (175°C). Grease and flour a 9×5-inch loaf pan.
2. Mix Dry Ingredients: In a medium bowl, whisk together the flour, baking powder, baking soda, and salt. Set aside.
3. Cream Butter and Sugar: In a large mixing bowl, beat the softened butter and granulated sugar together until light and fluffy, about 3-4 minutes.
4. Add Eggs and Flavorings: Add the eggs one at a time, mixing well after each addition. Then, stir in the vanilla extract, lemon zest, and lemon juice until fully combined.
5. Alternate Dry and Wet Ingredients: Gradually add the flour mixture to the butter mixture, alternating with the buttermilk. Begin and end with the flour mixture. Mix until just combined.
6. Fold in Blueberries: Gently fold in the blueberries, being careful not to overmix to keep the berries intact.
7. Pour Batter: Pour the batter into the prepared loaf pan, smoothing the top with a spatula.
8. Bake: Place the loaf in the preheated oven and bake for 50-55 minutes or until a toothpick inserted into the center comes out clean.
9. Cool: Once baked, remove the loaf from the oven and allow it to cool in the pan for about 15 minutes. Then, transfer it to a wire rack to cool completely.

These clear steps will guide you in creating a moist and flavorful Blueberry and Lemon Loaf that is sure to impress.
