Creating Lemon Blueberry Cake is a straightforward process when you follow these easy steps:

1. Preheat the Oven: Set your oven to 350°F (175°C). Grease and flour a 9×13 inch baking dish.
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, cream the softened butter and granulated sugar until light and fluffy.
4. Add Eggs: Beat in the eggs one at a time, mixing well after each addition.
5. Incorporate Buttermilk and Lemon: Add the buttermilk, lemon zest, and lemon juice to the mixture, stirring until well combined.
6. Gradually Combine Dry Ingredients: Slowly add the dry ingredients to the wet ingredients, mixing until just combined. Be careful not to overmix to keep the cake tender.
7. Fold in Blueberries: Carefully fold in the fresh blueberries, ensuring they are evenly distributed throughout the batter.
8. Pour into Pan: Pour the batter into the prepared baking dish, smoothing the top with a spatula.
9. Bake: Place the dish in the oven and bake for 30-35 minutes, or until a toothpick inserted in the center comes out clean.
10. Cool: Once baked, remove the cake from the oven and let it cool in the pan for 15-20 minutes. Transfer to a wire rack to cool completely.
11. Add Glaze or Frosting: If desired, drizzle a lemon glaze or frost the cooled cake with cream cheese frosting.
12. Dust with Powdered Sugar: For an extra touch, dust the top with powdered sugar before serving.
