Preheat your oven to 325°F. Prepare a 10-inch tube pan by spraying with nonstick cooking spray and lightly dusting with flour.
For the cake base, distribute ½ cup of chopped pecans evenly in the bottom of the pan.
In a large mixing bowl, cream together the butter and cream cheese until smooth. Gradually add the brown sugar, beating until it’s light and fluffy (about 4-5 minutes).
Incorporate the eggs one at a time, ensuring each is well mixed before adding the next.
Carefully fold in the cake flour, being careful not to overmix.
Gently blend in the vanilla extract and the remaining pecans.
Spoon the batter into the prepared pan and place on a baking sheet.
Bake for approximately 90 minutes or until a toothpick inserted into the center comes out clean.
Allow the cake to cool in the pan for 15 minutes before transferring to a wire rack to cool completely.
