Chocolate Fudge Squares with Mocha Glaze

Fudge Squares:
1 stick butter, softened
1 cup granulated sugar
1 egg
1 cup all-purpose flour
1/4 teaspoon baking powder
1 ounces unsweetened chocolate-melted (I used semi-sweet, mostly because Publix didn't carry unsweetened)
1/2 cup milk
1 teaspoon vanilla extract

Glaze:
1 heaped cup of confectioner's sugar
1 tablespoon butter, softened
1 ounce unsweetened chocolate, melted
1 teaspoon vanilla extract
1/4 cup brewed double strength coffee, preferably from dark roast beans

Preheat oven to 350 degrees.  Butter an 8inch square baking pan.  ( I used round because I don't own a square pan)
In a large bowl, cream butter with sugar and egg.
In a small bowl, sift together flour and baking powder.  Add to butter mixutre, then add melted chocolate. Do not over beat. stir in milk and vanilla, just to blend.
Pour the batter into prepared pan.  Bake until the edges begin to pull away from the sides of pan, about 30 minutes.  Transfer cake to a rack and let cool completely.
Glaze:
In a medium bowl, combine confectioner's sugar, butter, chocolate, and vanilla with a wire whisk.  Stir in coffee and whisk until smooth.  Refrigerate the glaze until cool, then pour over cake and then cut the cake into squares.
