adapted from Toll House

1 2/3 cup granulated sugar

3/4 cup cocoa powder

3/4 cup butter

2 Tablespoons strong coffee or water

2 large eggs

2 teaspoons vanilla extract

1 1/3 cup all-purpose flour

1/2 teaspoon baking powder

1/4 teaspoon salt

3/4 cup chopped walnuts

1/4 cup chocolate chips or coarsely chopped chocolate bar

Preheat oven to 350 degrees.  Grease and flour a 9x13-inch baking pan.  (I used a 10-inch round cake pan.)

Combine butter and cocoa powder in a small bowl, and place over a pot of simmering water.  Make sure that the simmering water down not touch the bottom of the bowl.  Add the coffee or water and stir to melt the ingredients.  

In a medium sized bowl whisk together the eggs and the sugar.  Add the vanilla extract.  When the butter and chocolate have melted and come together, slowly stir the chocolate mixture into the sugar mixture.  

Add the flour, baking powder and salt.  Stir to combine.  Fold in the nuts, saving a small handful for the top of the brownies if you like.  

Pour the batter in the pan, sprinkle with chocolate chips or chocolate chunks and remaining nuts.  Bake for 18-25 minutes.  

Remove from the oven and cut into bars.
