Making Lemon Blueberry Cake is easy if you follow these clear and concise steps:

1. Preheat Oven: Preheat your oven to 350°F (175°C) and grease a 9×13 inch baking pan.
2. Mix Dry Ingredients: In a large bowl, whisk together the flour, baking powder, and salt.
3. Cream Butter and Sugar: In another bowl, cream the softened butter and sugar until light and fluffy, about 3-4 minutes.
4. Add Eggs and Flavorings: Add the eggs, lemon zest, and vanilla extract. Mix until well combined.
5. Combine Wet Ingredients: Gradually add the flour mixture and the whole milk, alternating between the two until just combined.
6. Fold in Blueberries: Gently fold in the blueberries, being careful not to break them.
7. Add Lemon Juice: Stir in the lemon juice for that extra pop of flavor.
8. Pour Batter: Pour the batter into the prepared baking 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 in the center comes out clean.
10. Cool: Remove from the oven and allow the cake to cool in the pan for 15-20 minutes, then transfer to a wire rack to cool completely.
