Grease pie plate well and preheat oven to 350 degrees.
Melt butter in medium-sized saucepan. Remove from heat and slowly add in the following ingredients in order, stirring after each addition: cocoa, brown sugar, granulated sugar, eggs, vanilla extract, gluten-free flour mix, and nuts (if used).
Pour filling into prepared pie plate.
Bake for about 25 minutes. Test with a toothpick. When the pie is done, the toothpick should have just a smidge of chocolate on its tip. You don’t want to overcook this pie.
