Preheat the oven to 350°F (175°C) and grease a Bundt pan with butter or cooking spray.
In a bowl, whisk together flour, baking powder, baking soda, and salt.
In a large mixing bowl, cream the softened butter and sugar until light and fluffy, about 3 minutes.
Beat in the eggs one at a time, then add the vanilla extract, lemon zest, and lemon juice.
Gradually add the dry ingredients, alternating with the sour cream. Begin and end with the dry ingredients. Mix until just combined.
Gently fold in the blueberries, being careful not to crush them.
Pour the batter into the prepared Bundt pan, spreading it evenly.
Bake for 55-60 minutes, or until a toothpick inserted comes out clean.
Let the cake cool in the pan for 10 minutes, then transfer it to a wire rack to cool completely.
Dust with powdered sugar or drizzle with a lemon glaze before serving. (Optional)
