Creating this Lemon Blueberry Cake is straightforward if you follow these simple steps:

1. Preheat Oven: Preheat your oven to 350°F (175°C). Grease and flour a 9-inch round cake pan, or line it with parchment paper for easy removal.
2. Mix Dry Ingredients: In a 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 3-5 minutes.
4. Add Eggs: Add the eggs one at a time, mixing well after each addition.
5. Incorporate Wet Ingredients: Mix in the lemon zest, lemon juice, and vanilla extract until well combined.
6. Combine Mixtures: Gradually add the dry mixture into the wet mixture. Mix until just combined, careful not to over-mix.
7. Fold in Blueberries: Gently fold in the fresh blueberries, ensuring they are evenly distributed throughout the batter.
8. Pour Batter: Pour the batter into the prepared cake pan and smooth the top with a spatula.
9. Bake: Place in the preheated oven and bake for 30-35 minutes, or until a toothpick inserted into the center comes out clean.
10. Cool: Allow to cool in the pan for about 15-20 minutes, then carefully transfer to a wire rack to cool completely.
11. Dust with Powdered Sugar: Optionally, once the cake is completely cooled, dust the top with powdered sugar for a lovely finish.

Following these steps will lead you to create a delightful, moist Lemon Blueberry Cake that is sure to impress!
