Preheat oven to 350 degrees F. Coat a 9×13 baking dish with cooking spray and set aside. Using a stand mixer fitted with the paddle attachment (or a large mixing bowl with a hand mixer), combine the butter, sugars, eggs and vanilla and beat until combined.
In a separate bowl, combine the flour, baking powder, baking soda, salt and cinnamon. Mix well. Gradually add to the butter mixture and beat on medium-low speed until just combined.
Add the sour cream and mix until just combined. Stir in the cherries. Pour the batter into the prepared pan, spreading in an even layer.
In a small bowl, combine the brown sugar, flour, cinnamon and melted butter. Stir until crumbly. Sprinkle crumbles over the cake batter in the pan and bake in the preheated oven for 30-40 minutes, or until a toothpick inserted into the center comes out clean. Let cool.
Using a stand mixer fitted with the whisk attachment (or a large mixing bowl with a hand mixer), powdered sugar and milk. Mix on medium speed until glaze is free of lumps. Drizzle over the cooled coffee cake, cut into squares and serve!
