Method
Preheat oven to 350°F.
Grease a 9 x 13 inch cake pan ( aluminum is fine ) with butter from butter wrappers.
Beat the 1 1/2 sticks melted butter and sugar together in a large bowl until blended. Beat in the eggs 1 at a time, then stir in water and vanilla , sprinkle the salt and baking powder then mix in. Do the same with cocoa, finally stir flour in until just blended.
Put the candy bars in food processor or blender and pulse on low until all bars have been reduced to coarse crumbles. Fold the crumbs into batter thoroughly, scrape the batter into the prepared pan. Bake for 30 minutes, until center is set, the edges look a bit crusty, and top of brownies start to crack a little. Cool completely on baking rack then cut into squares.
