Fudgy Chocolate Pie

This Warm, Chocolaty Pie Only Requires 6 Ingredients!
Happy New Year! As many of you were probably up late last night, and may not be in the mood to bake, I wanted to share a warm, delicious recipe that will take little effort. This 6-ingredient dessert is both easy and quick, and best of all, you can eat it almost right out of the oven because it’s best served warm. It’s called Fudgy Chocolate Pie and it’s more cake-like than pie, but it is fudgy and chocolaty and has the heavenly flavour of vanilla. It’s the perfect comfort treat on a lazy day. If you’re a nut fan like I am, adding chopped walnuts and serving with vanilla ice cream will only make this dessert better. Enjoy and have a sweet and scrumptious 2010!
FUDGY CHOCOLATE PIE
1/2 cup butter or margarine, melted
3/4 cup granulated sugar
1/3 cup cocoa
1/4 cup all-purpose flour
2 eggs
1 tsp vanilla
1/3 cup chopped walnuts (optional)
Preheat oven to 350 degrees. Grease a 9 inch pie plate and set aside.
In a large bowl, mix together the melted butter, sugar, cocoa and flour. Beat in the eggs and vanilla (stir in walnuts if you desire). Pour batter into pie plate and bake for 15-20 minutes or until the edges are firm to the touch but the middle is still soft.
Cool for 5 to 10 minutes or until the centre firms up, then serve warm.

I have tried doing this in the past, except I can never get it working as they are suppose to. Advice?
