Turn the waffle iron to medium heat setting and preheat.

Melt the butter and chocolate together in a bowl or double boiler over simmering water or in the microwave. Set aside.

In a bowl, combine the flour, salt, sugar, and baking powder.

In another bowl, whisk the egg with the milk and vanilla. Add the chocolate and butter mixture and blend well.

Add the chocolate mixture to the dry ingredients; mix well.

Bake in the hot waffle iron for about 3 to 4 minutes. Serve waffles with whipped cream or ice cream and chocolate fudge sauce or caramel sauce.
