Preheat the oven to 325 degrees. Grease an 8 x 8 inch square pan.
In a medium saucepan, combine the sugar, butter and water (or liquid cacao). Cook over medium heat until boiling. Remove from heat and stir in chocolate chips and chopped wafers until melted and smooth.
Mix in the eggs (be sure to temper the eggs a bit with the warm mixture) and vanilla. Combine the flour, baking soda and salt and then stir into the chocolate mixture. Spread evenly into the prepared pan.
Bake for 25 to 30 minutes in the preheated oven, until brownies set up.
Be sure to not overbake – better a little under than over. Cool in pan and cut into squares. I always use a plastic knife to cut brownies – makes better cuts.
