Making Blueberry Lemon Delight is simple when you follow these easy steps:

1. Preheat the Oven: Start by preheating your oven to 350°F (175°C). Grease and flour an 8-inch square baking dish.
2. Mix Dry Ingredients: In a bowl, whisk together the flour, baking powder, and salt. Set aside.
3. Cream Butter and Sugar: In a larger bowl, beat the softened butter and granulated sugar together until light and fluffy.
4. Add Eggs: Add the eggs one at a time, mixing well after each addition.
5. Incorporate Flavors: Stir in the lemon zest, lemon juice, and vanilla extract until fully combined.
6. Combine Mixtures: Gradually add the dry ingredients to the wet mixture, mixing just until incorporated. Be careful not to overmix.
7. Fold in Blueberries: Gently fold in the fresh blueberries to ensure they are evenly distributed.
8. Pour Batter: Pour the batter into the prepared baking dish, spreading it evenly.
9. Bake: Place in the preheated oven and bake for 30 minutes, or until a toothpick inserted in the center comes out clean.
10. Cool the Dish: Once baked, remove from the oven and allow it to cool in the baking dish for about 10 minutes. Then transfer to a wire rack to cool completely.
11. Dust with Powdered Sugar: Before serving, dust the top with powdered sugar for an elegant finish.
