Steps to make this cake:
Preheat your oven to 325 degrees.
Using a hand or stand mixer, blend the butter, brown sugar, and granulated sugar together on medium speed until light and fluffy (approximately 5 minutes).
Add the eggs to the bowl one at a time, mixing well after each addition before adding the next egg.
Next, add the vanilla extract and mix.
Whisk the salt and baking powder into the flour mixture.
Add the flour mixture ½ c to 1 c at a time on low speed until combined alternating with the sour cream.
Using a spoon or spatula scrape down the sides of the bowl and mix ensuring that the batter is fully mixed together.
Spray a 12-cup bundt pan with baking spray.
Pour the batter into the pan and spread it evenly.
Bake for about an hour and 10 minutes. The cake is done once an inserted toothpick comes out clean.
Remove the cake from the oven and allow it to cool for about 20 minutes before removing it from the pan. Allow the cake to continue to cool on a wire rack before adding the icing.
To make the glaze:
In a saucepan, add the butter and melt on medium heat.
Whisk in the light brown sugar and milk. Simmer until the sugar is well blended- approximately 5 minutes.
Whisk in the powdered sugar and simmer for approximately two minutes.
Turn off the heat and add the vanilla extract.
Fold in half of the pecans and reserve the rest to top the cake with.
Pour the glaze over the cake as desired then sprinkle the top of the cake with the remaining pecans.
Serve once the glaze has set.
