Walnut Brownies

These cake-like brownies have a very rich chocolate flavor. I used unsweetened chocolate when I made them, but I think in the future I will use semi-sweet chocolate to make them sweeter.

Ingredients:
1 stick butter
5 squares semisweet Baker's chocolate (5 oz)
1 cup water
2 cups sugar
1/2 tsp vanilla extract
1 3/4 cups all-purpose
3/4 cup self-rising flour
1/2 cup cocoa powder
1 cup mayonnaise, room temperature
1 cup chopped walnuts
Confectioners sugar, for dusting on top

Optional Chocolate glaze:
4 squares semi-sweet Baker's chocolate
3 tbsp unsalted butter1 tbsp water

Directions:
Preheat the oven to 325 degrees.
In a medium saucepan over low heat, melt together the chocolate squares, butter, sugar, vanilla extract, and 1 cup of cold water. Stir continuously until the mixture is smooth. Do not allow to boil.
Whisk together the flours and cocoa powder in a large bowl. Make a well in the center and add the mayonnaise and 1/3 of the chocolate mixture. Mix with a wooden spoon until smooth. Mix in the rest of the chocolate mixture. Fold in the chopped walnuts.
Pour the batter into a greased square baking pan, and bake for 1 hour. Take the cake out of the oven and let cool.
For the chocolate glaze:
Melt 3 tbsp of butter and 4 squares of semisweet chocolate with 1 tbsp of water in a small saucepan over low heat. Let the glaze cool, and spread over the brownies. Dust the brownies with confectioners sugar.
