To make the topping: In a medium bowl, mix the brown sugar, granulated sugar, cinnamon, and melted butter together until the mixture resembles wet sand. Stir in the nuts; set aside.
Preheat the oven to 350°. Grease a 9×13 inch square baking pan and set aside.
To make the coffee cake: In a medium bowl, whisk together the flour, baking powder, baking soda, cinnamon, and salt; set aside.
In a medium bowl, whisk together the buttermilk, brown sugar, granulated sugar, eggs, and melted butter until smooth. Gently fold the egg mixture into the flour mixture with a rubber spatula and stir until the batter looks smooth and well combined. Stir in blueberries and lemon zest.
Pour mixture into prepared pan, spread into corners, and level surface with rubber spatula. Sprinkle the topping evenly over the batter. Bake until the top is golden and a toothpick inserted into the center comes out with just a few crumbs attached, 40 to 45 minutes. Let the cake cool on a wire rack for 15 minutes before serving.
To make the lemon drizzle, in a small bowl, whisk together the confectioners’ sugar and ½ tablespoon of the lemon juice. The mixture should be thick but pourable. Add up to another ½ tablespoon of lemon juice if the mixture is too stiff. Drizzle over the top the coffee cake. Let harden, about 10 minutes, before serving.
