- Place 1 1/2 cups of peanuts in the bottom of an ungreased 11″x 7″ pan.
- In a large saucepan over low heat, melt butter and peanut butter chips, stirring until smooth.
- Remove from heat and stir in condensed milk and marshmallows until smooth and well-blended.
- Pour the peanut butter mixture over the peanuts in the pan. Sprinkle the remaining 1 1/2 cups of peanuts over the top. If desired, lightly sprinkle with sea salt for saltier bars.
