Combine cream cheese, sugar, eggs, Creme de Cacao, sour cream, and triple sec in a bowl.

Beat the mixture until it is smooth and thick.

Pour the cream cheese mixture into the graham cracker pie crust.

Bake in a preheated oven at 375°F (190°C) for 20 minutes.

Mix the sour cream topping (no specific instructions given, assuming just stirring it to make it smooth).

Spread the sour cream topping evenly over the baked pie.

Return the pie to the oven and bake for an additional 5 minutes.

Remove the pie from the oven and let it cool completely.

Refrigerate for at least 2 hours before serving.

Garnish with whipped cream or Cool Whip before serving.
