I want to make some brownies to take to work.

To make brownies, preheat the oven to 350 degrees F and grease an 8-inch square baking pan. In a medium bowl, mix together 1 cup of plain flour, 1/2 cup of cocoa powder, and 2 teaspoons of baking powder. In a larger bowl, mix together 1/2 cup of butter, 1 cup of sugar, 1/2 cup of chopped nuts (optional), and 1/2 cup of brewed coffee (or other liquid like juice, milk or soda). Beat in 2 eggs, stir in the dry ingredients, then pour the batter into the prepared pan. Bake 25 to 30 minutes, cool and cut into squares.
