Really standard brownies

These aren't decadent, over-the-top brownies, but do we need to have those all the time? These are sweet and tasty and moderate, all nice things.

2 ounces unsweetened chocolate
1/4 cup butter
1 cup sugar
1 egg
1/8 tsp salt
1/2 cup flour
1 tsp vanilla

Preheat the oven to 300. Butter an 8" square pan.
In a saucepan over very, very low heat, melt together the butter and chocolate. Remove from the heat and stir in other ingredients. Spread in the prepared pan and bake for 30 minutes.
