¾ cup Mazola or Nucoa margarine
½ cup granulated sugar
½ cup firmly packed brown sugar
½ cup Karo dark corn syrup
1 tablespoon vanilla
4 cups quick oats
1 (6-ounce) package semi-sweet chocolate chips
⅔ cup Skippy creamy or chunk style peanut butter
Grease 1 (13 × 9 × 2-inch) baking pan. Blend margarine and sugars
in mixing bowl. Stir in corn syrup and vanilla, mixing well. Mix in
oats. Pat dough into bottom of prepared pan, moistening hands to
prevent sticking. Bake in 350°F. (moderate) oven 20 to 25 minutes.
Cool slightly. Melt chocolate chips and peanut butter over boiling
water, stirring constantly. Spread over baked layer. Chill to set
chocolate. Cut into bars. Makes about 6 dozen (3 × ½-inch) bars.
