I promised this recipe to my sister a while ago.... Sorry it took me so long.
I have been using this brownie recipe for a while now. It rocks.
It is also easy to make a 1/4 batch, which is perfect for 4 generous servings. The only special trick is that you can't have the butter/sugar portion too warm, otherwise your brownies will taste like eggs. Not so great...
Here are the measurements for those of you who aren't that great at kitchen math yet!
1/2 stick butter, melted
1/2 c sugar
1/2 t vanilla
3 T cocoa powder
1/4 c flour (whole wheat works fine, too)
1/8 t baking powder
1/16 t salt (I just eyeball half of an 1/8th of a teaspoon)
