Apple Crumb Cake with Brown Sugar Glaze

I made this recipe as a Thanksgiving dessert -- it isn't too sweet, but it is delicious.  It could probably make for a decadent breakfast food as well.

cake

1 stick salted butter

1.5C brown sugar

2 large eggs

2C all-purpose flour

1 tsp baking soda

1 tsp ground cinnamon

1/2 tsp salt 

1C sour cream

1 tsp vanilla extract

2 Granny Smith apples, cored and chopped (I used my Pampered Chef Manual Food Processor)

crumble topping

1/2C brown sugar

1/2C all-purpose flour

1/2 tsp ground cinnamon

4 tbs salt butter, softened

8. Pour batter into prepared baking dish, spreading out to the edges.
