I guess, no one can control their portion size these days :)
Here is the recipe if you'd like to make it at home.
1 9" refrigerated Pillsbury pie crust
6 table spoons unsalted butter
1 cup maple syrup
3/4 cup sugar
3 large eggs
1 teaspoon vanilla extract
1/2 teaspoon salt
2 cups pecans, coarsely chopped
Place pie crust into 9" glass dish. Fill the pie shell with pecans.
In a medium saucepan, combine the sugar, maple syrup and butter. Heat over medium heat until butter melts and remove from the heat.
In a medium bowl, beat eggs until frothy. Add vanilla and salt.
Gradually beat in hot syrup mixture, stirring constantly.
Pour the mixture into the pie shell.
Bake at 350'F for 1 hour. Let it chill and refrigerate overnight before serving.
