Preheat oven to 350-degrees. Spray a 9-inch springform pan with non-stick cooking spray and lightly flour. Prepare crumb topping by mixing sugar, flour, and butter until crumbly, and set aside.
In a small bowl, whisk together flour, baking powder, and salt. Set aside. In a large bowl, beat butter and sugar until light and fluffy. Add eggs, vanilla, and milk. Mix in lemon zest. Add flour mixture and mix just until combined. Stir in berries.
Spread batter evenly into prepared pan. Sprinkle with crumb topping. Bake for 45 minutes. Allow to cool for 10 minutes on cooling rack. Drizzle with icing.
