Question: Can I make this recipe less rich?

I have a recipe for a Dark Chocolate Pie. The recipe ingredients are as follows:

2 cups dark chocolate
1/2 stick (2oz) unsalted butter
1 Tbsp brandy
1/2 cup sugar
3 eggs

I made this and while it turned out well and tasted yummy, we could really only eat a few bites because it is so rich! I know this recipe is intended to be rich, but I was wondering if there was a way I could tone down on the richness factor at all? I am a novice baker so I'm sorry if the answer is obvious.
