2 ounces dark unsweetened chocolate
1/2 cup butter
1/2 cup semisweet chocolate chips
2 eggs
1 cup granulated sugar
1/2 teaspoon vanilla extract
1/2 cup all-purpose flour
2/3 cup broken pecans

In the top of a double boiler over simmering water, melt dark chocolate, butter and semisweet chocolate chips. Stir to mix.

In a large mixing bowl, beat eggs, sugar and vanilla extract. Stir in flour and the chocolate mixture. Add pecans and marshmallows. Pour mixture into a heavily-buttered 8-inch square baking pan. Bake in a preheated 350 degree F oven 20 to 25 minutes. Let cool, then cut into squares.
