Method
Bring brown sugar, butter, and milk to boil. Remove from heat and add vanilla. Put half of this mixture in the bottom of a Bundt pan and enough pecans to cover bottom. Roll each biscuit in cinnamon-sugar mixture (1/2 cup sugar plus 2 teaspoons cinnamon) and stand up in pan. Sprinkle leftover cinnamon-sugar mixture on top. Add the rest of the caramel mixture on top. Bake 30 minutes at 350 degrees. Flip out on to plate.
