Creating the Lemon Blueberry Yogurt Loaf is simple if you follow these easy steps:

1. Preheat Oven: Preheat your oven to 350°F (175°C). Grease a 9×5 inch loaf pan with butter or cooking spray.
2. Mix Dry Ingredients: In a medium bowl, stir together the all-purpose 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: Add the eggs one at a time, mixing well after each addition. Then, add the vanilla extract, lemon zest, and lemon juice, and mix until combined.
5. Incorporate Yogurt: Stir in the plain yogurt, mixing until just combined.
6. Combine Mixtures: Gradually add the dry ingredients to the wet ingredients, stirring gently until just combined. Do not over-mix.
7. Fold in Blueberries: Gently fold in the blueberries, being careful not to crush them.
8. Transfer to Pan: Pour the batter into the prepared loaf pan, smoothing out the top.
9. Bake: Place the loaf in the preheated oven and bake for 40-45 minutes, or until a toothpick inserted in the center comes out clean.
10. Cool: Remove the loaf from the oven and allow it to cool in the pan for about 10-15 minutes. Then, gently transfer it to a wire rack to cool completely.

These steps will guide you in making a delectable Lemon Blueberry Yogurt Loaf that is sure to impress.
