In a large bowl, add your white sugar and pumpkin pie spice. Mix until well combined.
Cut your biscuit discs into quarters. I like to give them a little roll into a ball because I think it looks cuter when done baking and prevents browning.
Add your biscuit pieces into the large bowl and shake/mix together until the dough is coated on all sides. Continue until all pieces of biscuit are coated.
Get your bundt pan and spray it with non stick spray. Each can of biscuit dough will be 1 layer. So add the first layer.
Chop up the apples into 1 " pieces and spread 1 apple over the first layer of biscuit dough.
Add a second layer of biscuit dough followed by the other half of the apples.
Add a third layer of biscuit dough.
Over your stove sop, get a small saucepan over medium heat. Add your butter and brown sugar. Boil for 1 minute, stirring to make sure its completely incorporated. Pour over your biscuit dough. Top with chopped pecans.
Bake at 350 degrees for 35-40 minutes.
