1 cup light corn syrup
1 cup sugar
1 cup peanut butter -- smooth or crunchy
2 quarts popped popcorn
Combine corn syrup, sugar and peanut butter in a large saucepan. Bring to a boil while stirring constantly. Over low heat, boil for three minutes. Remove from the heat and add popcorn. Toss with wooden spoons (mixture will be hot) to coat well and press into a greased 13 x 9 x 2 inch pan. Cool and cut into squares.
