Easy Dark Chocolate Brownies

These brownies come together really quickly and are cakey and chocolatey. I made these for a movie night, and they were a hit.

Ingredients
4.25 ounces dark chocolate (I used Hershey Dark)
3/4 cup butter
1 cup sugar
2 eggs
1 teaspoon vanilla
1 cup flour

Instructions
Preheat the oven to 325 F with a rack in the lower third. Spray a 8x8 pan with cooking spray. Melt the chocolate and butter, stirring frequently until smooth. Remove from the heat and stir in the sugar. When the mixture has cooled, add in the eggs one at a time. Stir in the vanilla. Add the flour and stir until well blended. Scrape the batter in the pan and spread it evenly.
Bake 30 minutes. Cool the brownies in the pan.
Yields 16 servings.
