Preheat oven to 350°F. Grease and flour a 9-inch springform pan.
Prepare the crumb topping by mixing sugars, cinnamon, salt, melted butter, and flour. Set aside.
In a separate bowl, whisk together flour, baking powder, baking soda, and salt for the cake.
Cream butter and sugar in a large bowl until light and fluffy. Beat in eggs one at a time.
Mix in sour cream, lemon juice, vanilla extract, and lemon zest until combined.
Gradually add the dry ingredients to the wet mixture until just combined.
Gently fold in blueberries.
Spread the batter evenly into the prepared pan. Sprinkle crumb topping over the batter.
Bake for 50–60 minutes or until a toothpick inserted in the center comes out clean.
Cool completely in the pan. Mix powdered sugar and lemon juice for the glaze and drizzle over the cooled cake.
