Using a stand mixer or a hand mixer, beat ice cream for 2 minutes on low speed, or just until softened.
Add chopped pumpkin pie pieces and beat for 30-45 seconds. Just to blend.
If not serving immediately return to freezer in a sealed container.
To serve, place a small slice of pie in a small bowl, scoop 1-2 scoops ice cream mix, top with whipped topping and mini chocolate chips.
