Making a delicious Lemon Blueberry Bundt Cake is simple if you follow these easy steps:

1. Preheat Oven: Preheat your oven to 350°F (175°C). Grease and flour a bundt pan to prevent sticking.

2. Mix Dry Ingredients: In a medium bowl, combine flour, baking powder, baking soda, and salt. Whisk together until well mixed.

3. Cream Butter and Sugar: In a large bowl, cream the softened butter and granulated sugar together until light and fluffy, about 3-4 minutes.

4. Add Eggs and Vanilla: Beat in the eggs one at a time, ensuring each is fully incorporated before adding the next. Stir in the vanilla extract and lemon zest.

5. Incorporate Sour Cream: Mix in the sour cream gradually, mixing until the batter is smooth.

6. Combine Wet and Dry Mixtures: Gradually add the flour mixture to the wet ingredients, mixing until just combined.

7. Add Lemon Juice: Stir in the lemon juice, ensuring no lumps remain in the batter.

8. Fold in Blueberries: Gently fold in the fresh blueberries, being careful not to overmix to keep them intact.

9. Pour into Bundt Pan: Pour the batter into the prepared bundt pan, smoothing the top with a spatula.

10. Bake: Bake for 45-50 minutes, or until a toothpick inserted into the center comes out clean.

11. Cool: Once baked, remove from the oven and allow the cake to cool in the pan for about 15-20 minutes before inverting onto a wire rack to cool completely.

12. Prepare Glaze: While the cake is cooling, prepare the glaze by whisking together powdered sugar and lemon juice until smooth. Add milk to achieve your desired consistency.

13. Glaze the Cake: Drizzle the glaze over the cooled bundt cake and allow it to set before serving.
