Creating the incredible Lemon Blueberry Cake is a simple and enjoyable process. Follow these step-by-step instructions to make your cake:

1. Preheat Oven: Start by preheating your oven to 350°F (175°C). Prepare a 9×13 inch baking pan by greasing it lightly.
2. Mix Dry Ingredients: In a large bowl, whisk together the flour, sugar, baking powder, and salt until well combined.
3. Cream Butter: In another bowl, cream the softened butter until light and fluffy. This usually takes about 2-3 minutes.
4. Add Wet Ingredients: To the creamed butter, add the milk, eggs, lemon juice, and lemon zest. Blend well until smooth.
5. Combine Mixtures: Gradually add the dry ingredients to the wet mixture, stirring gently until just combined. Do not overmix.
6. Fold in Blueberries: Carefully fold in the fresh blueberries, ensuring they are evenly distributed throughout the batter.
7. Pour Batter: Transfer the batter to the prepared baking pan and smooth the top with a spatula.
8. Bake: Place in the preheated oven and bake for 30-35 minutes or until a toothpick inserted in the center comes out clean.
9. Cool: Remove from the oven and allow the cake to cool in the pan for about 20-30 minutes. Then transfer to a wire rack to cool completely.
10. Dust with Powdered Sugar: Once cool, you can dust the top of the cake with powdered sugar for an elegant finish.

These straightforward steps will help you create a beautiful and delicious Lemon Blueberry Cake that everyone will adore.
