Creating an amazing Lemon Blueberry Cake is a simple process when you follow these easy steps:

1. Preheat Oven: Start by preheating your oven to 350°F (175°C). Grease and flour a 9×13-inch baking pan.
2. Mix Dry Ingredients: In a large mixing bowl, combine the flour, baking powder, and salt. Whisk together until well blended.
3. Cream Butter and Sugar: In another bowl, cream the softened butter and granulated sugar together until light and fluffy.
4. Incorporate Eggs: Add the eggs one at a time to the butter mixture, beating well after each addition.
5. Add Wet Ingredients: Stir in the milk, lemon juice, lemon zest, and vanilla extract until smooth.
6. Combine Mixtures: Gradually add the dry ingredients to the wet mixture, stirring until just combined. Be careful not to overmix.
7. Fold in Blueberries: Gently fold in the fresh blueberries to ensure they are evenly distributed without crushing them.
8. Pour Batter: Pour the batter into the prepared baking pan, spreading it evenly.
9. Bake: Bake in the preheated oven for 30-35 minutes or until a toothpick inserted in the center comes out clean.
10. Cool: Once baked, allow the cake to cool in the pan for about 15-20 minutes before transferring it to a wire rack to cool completely.
11. Prepare Glaze: While the cake is cooling, mix the powdered sugar with a few tablespoons of lemon juice until smooth to create a glaze.
12. Glaze the Cake: Once the cake has cooled completely, drizzle the glaze over the top, allowing it to drip down the sides.

This step-by-step process will guide you in creating a Lemon Blueberry Cake that not only looks fantastic but also tastes incredible!
