Preheat oven to 350 degrees. Coat a bundt pan with nonstick cooking spray. Line the pan with half of the pecans and half of the raisins.
In a small bowl, combine the granulated sugar and cinnamon. Cut each biscuit into quarters. Roll biscuit pieces into balls and dip in the cinnamon-sugar mixture.
Place half of the biscuit balls into the bundt pan evenly. Repeat with another layer of raisins, pecans and dough.
In a small saucepan, melt the butter and brown sugar together and whisk to combine. Pour evenly over the dough. Place a baking sheet on the rack underneath the bundt pan to catch any drips. Bake for 1 hour. Allow to cool before turning out of the pan.
