Preheat oven to 350 degrees F (175 degrees C). Grease an 8x8 inch baking dish.
In a medium bowl, cream together the melted butter and sugars. Beat in the eggs and vanilla. In a separate bowl, combine the flour, baking powder, and salt. Gradually stir the dry ingredients into the egg mixture. Mix in the chopped Halloween candy.
Spread the batter into the prepared baking dish. Bake for 25 to 30 minutes in the preheated oven, or until the top is golden brown. Allow to cool before cutting into squares.
