Preheat the oven to 425F. Take pie crusts out of freezer to thaw.
Line a baking sheet with foil and spray with baking spray. Wash and dry sweet potatoes using a paper towel. Pierce them with a fork several times, place them on the prepared baking sheet and bake for 45-55 minutes, or until very tender.
Once the sweet potatoes are ready, take them out of the oven and let them cool. After they're cool to the touch, peel and discard the skin.
Place the frozen pie crusts in the oven, prick a few holes with a fork, and place in the oven to lightly brown for 7-10 minutes
Place the sweet potato in a mixing bowl and mash using a stand mixer or handheld mixer on medium speed for about 6-8 minutes to blend the sweet potatoes until they are pretty smooth. Next, add the melted butter and continue mixing till thoroughly combined. Next, add eggs one at a time and mix on low speed to combine.
Add white sugar, brown sugar, nutmeg, orange juice and zest, cinnamon and a pinch of salt. Continue mixing until everything until fully incorporated. Finally, add evaporated milk and vanilla, and mix until fully combined.
Pour the filling into the pie crust and bake at 350℉ for about 50-60 minutes or until the top is nicely browned.
Remove the pie from the oven, and allow it to cool for at least 30 minutes. Top with whipped cream and cinnamon sprinkled on top.
