1. Preheat oven to 350 degrees F. In a mixing bowl, mix together the dry ingredients (flour, sugar, cocoa powder, baking powder, and salt).
2. In another bowl, mix the wet ingredients (water, oil, and vanilla). Add the dry mixture into the wet mixture and stir until just combined. Stir in the nuts.
3. Spread batter into an 8" or 9" square baking pan. Bake for 15 to 20 minutes, but keep checking for preferred doneness after 10 minutes - just eyeball it until it's as gooey or chewy as you like!
