In a medium saucepan, brown the butter. Once browned, add in your maple syrup and let the mixture boil while you stir it for 2 minutes. Allow this mixture to cool down for 10-15 minutes before adding it to the egg and sugar mixture.
6 tablespoons unsalted butter, 1 cup pure maple syrup
In a large bowl, whisk together the eggs, vanilla extract, brown sugar, maple sugar, cornstarch, and salt until combined.
1/4 cup packed light brown sugar, 1/4 cup maple sugar, 3 large eggs, 1 ½ teaspoons vanilla extract, 1/4 teaspoon salt
Gently pour the melted butter mixture onto the egg mixture, whisking continuously to ensure the eggs don't cook.
Fill the pie crust with the pecans then pour the maple syrup filling evenly over the pecans.
1 & 1/2 cups pecans
Pour the filling into the prepared pie crust, spreading the pecans evenly.
Place the pie onto the baking sheet and bake for 10 minutes before lowering the temperature to 350F and baking for another 35-45 minutes.
Allow the pie to cool completely before serving to let the filling set.
