Heat oven to 350° and spray a bundt-cake pan with cooking spray.
Cut each cinnamon roll into 4 pieces.
Mix together the cinnamon and sugar in a small bowl.
In another small bowl combine the chopped apples, pecans, and add 1/4 cup of the cinnamon-sugar mixture. Mix until all the apples are coated well.
Layer half the apple mixture into the bottom of the bundt pan.
Dip half of the cut cinnamon roll biscuits into the remaining cinnamon sugar mixture and layer on top of the apples.
Top with the remaining apple mixture.
Take the remaining cut cinnamon roll biscuits and dip into the cinnamon sugar and layer on top of the apples.
Drizzle the melted butter over top.
Cook for 35-38 minutes. You might have to cover the bundt pan loosely with tin foil the remaining 10 minutes so the top does not burn.
Let cool for a few minutes in the bundt pan and then invert the bundt pan onto the serving plate.
Drizzle the icing that was included in the cinnamon roll cans over the monkey bread. If you want pretty lines, put the icing into a Ziploc bag and cut the corner, and then drizzle.
