Line a 9-inch pie dish with the pie crust. Place on a sheet pan.
In a large bowl, whisk together the melted butter, brown sugar, flour, vanilla, eggs and maple syrup. Stir in the pecans and pour into unbaked pie crust. Bake for 50-55 minutes, until the center is just set. Set aside to cool, then serve!
Notes
If using store bought crust, be sure to defrost overnight in the fridge before assembling the pie. Or you can make my super simple, quick & easy Homemade Pie Crust, it's foolproof every time! Serve with my 3-ingredient Homemade Whipped Cream (without Refined Sugar).
