Generously grease and flour a 10-inch tube cake pan or 12-cup Bundt cake pan.
In a mixing bowl with an electric mixer, beat the butter and brown sugar for about 5 minutes, or until light and fluffy. Add the eggs, one at a time, beating well after each addition.
In another bowl, combine the flour, baking soda, salt, and baking powder. Stir with a spoon or whisk to blend.
Combine the milk and vanilla.
Add the dry ingredients, alternating with milk and vanilla mixture and ending with the dry mixture. After each addition, beat just enough to combine.
Fold in the chopped pecans.
Spoon the batter into the prepared cake pan.
Place the cake in the cold oven and then set the temperature on 300 F.
Bake for about 1 hour and 15 minutes, or until the cake springs back when lightly touched with finger.
Let the cake stand 5 minutes and then turn out onto a rack to cool.
Before serving, sift powdered sugar over top or drizzle with a cake glaze.
