Ultimate Fudgy Brownies

We are celebrating summer and my brother-in-law's birthday today with these awesome brownies from one of my favorite cookbooks, "Granny's Drawers." I doubled the recipe for a 13x9 pan.

4 oz. Unsweetened chocolate (I used chocolate bark)
2 sticks margarine
2 cups sugar
4 eggs
1 1/2 cups all-purpose flour
1 tsp baking powder
1 tsp salt
2 tsp vanilla
1 cup chopped nuts (I used walnuts)

Preheat oven to 350 degrees. In a medium saucepan, melt the chocolate & margarine. Remove from heat and add the sugar and eggs and stir well. Add the flour, baking powder, salt and vanilla and stir well. Stir in nuts. Pour into a greased 13x9 pan and bake about 25 minutes or until edges pull away from the pan and a toothpick comes out of the center clean. Let cool completely before cutting.
