Preheat oven to 350. In large bowl of electric mixer, beat eggs 2 minutes at high speed. Beat in sugar. Blend in peanut butter, margarine and vanilla. Add flour, baking powder and baking soda, mixing well. Stir in 3/4 cup of chocolate candies. Spread batter in greased and floured 9 inch square baking pan. Sprinkle remaining candies on top. (Add a few more, if you like!). Bake 25 minutes. Do not overbake. Cool in pan on wire rack. Cut into squares after it has cooled completely. MasterCook formatted by Ethel Snyder
