Onolicious Brownies - cooking recipe

Ingredients

3/4 cup butter
3/4 cup ghiradelli premium baking cocoa
3 teaspoons pure vanilla extract
3/4 cup sugar
1/2 cup light brown sugar (not packed)
4 eggs
1 1/4 cups flour
1 teaspoon baking powder
1 teaspoon salt
1 cup nuts, chopped (pecans or macadamia nuts) (optional)
1/2 cup semi-sweet chocolate chips
confectioners' sugar, to finish

Preparation

Preheat oven to 350 degrees F.
Melt butter (low heat) in medium saucepan.
Add cocoa powder ; stir until well mixed.
Remove from heat.
Add vanilla and both sugars.
Add eggs to mixture, one at a time. (Mix each one in before adding the next.).
In a medium bowl mix the flour, baking powder, and salt.
Fold nuts and chips to the butter mix.
Add dry ingredients to the butter mixture.
Pour mixture into a 10x14 inch baking pan making sure it is spread out evenly. You can grease and flour the pan but I use parchment paper to ease the cleanup. [it will work in a 9x13 pan but will be thicker -- baking time will probably be affected -- I think an extra 5 minutes will do it].
Bake for about 30 minutes at 350 degrees F.
Slice when brownies have cooled. If you want it really sweet, sprinkle on a bit of confectioner's sugar to give it a nice finish.
Option: I sometimes I chop 1/2 cup dried cherries and 1/2 cup dried cranberries and add these to the mix in place of the nuts. and sometimes I add 1-2 cups mini marshmallows to the original recipe.
