If using a flat pie crust, line a 8”x8” (or 9”x9”) baking dish with foil, spray it with cooking spray and then place the crust into the bottom of the pan. If using a deep dish frozen pie crust, keep refrigerated/frozen until use.
Coarsely chop pecans and place on a baking sheet to toast in the oven. After approx. 1 min, @ 400° open the oven and gently shake the pan. Pecans are ready as soon as you can smell them. Remove from oven to rest.
Bake pie crust for 10-12 minutes until golden at the edges.
When the crust is removed from the oven, begin heating the fudge ingredients: In a saucepan, melt corn syrup, molasses, evaporated milk, white chocolate chips, and brown sugar until combined. Turn off the heat and stir in the vanilla and maple syrup.
Pour fudge over the crust and let cool until firm.
Notes
Can substitute dark karo corn syrup for molasses + light karo corn syrup, if desired
