Chocolate Chip Cookie Dough Pie

My friend, Tara, made this fabulous "pie" and it was so yummy that I had to share it.  This was gooey and rich, and topped off with whipped cream and chocolate sauce!

Chocolate Chip Cookie Dough Pie
 
2 3/4 all-purpose flour
1 1/2 teaspoons salt
1 teaspoon baking soda
1 1/4 teaspoons baking powder
1 cup (2 sticks) unsalted butter (softened)
1 1/2 cups packed light brown sugar
1/2 cup granulated sugar
3 large eggs
1 teaspoon vanilla extract
3 cups semisweet chocolate chips
2 cups chopped walnuts (optional)
 
Preheat oven to 350 degrees.  Grease two nine-inch pie plates; set aside.
 
Sift together the flour, salt, baking soda and baking powder in a large bowl.  In the bowl with an electric mixer, cream together butter, brown sugar and granulated sugar.  Next, add one egg at a time, beating until incorporated.  Beat in vanilla.  Add flour mixture, a little at a time, and mix until fully combined.  Fold in three cups of chocolate chips and if desired, walnuts.  Divide the dough between the prepared pie plates and smooththe tops with a spatula.
 
Bake for about 30 minutes or until pies are golden and slightly firm to the touch, but still soft. Let pies cool completely on a wire rack.  These tend to "bubble up" while baking, so I like to place them on a cookie sheet in the oven.
