Peanut Butter Butterscotch Bars

Put eggs, sugar, brown sugar, and butter in a large saucepan. Bring to a boil, then cook on low heat for 1-2 minutes, stirring constantly. Remove from heat. Add graham cracker and marshmallows. Stir well. Butter a 9″ x 13″ baking pan. Spread mixture into pan. Melt butterscotch chips and peanut butter in a small saucepan over medium-low heat. When melted, spread over the top of the bars. Chill for 5-6 hours before cutting into squares.
