Frosted Peanut Butter Bars

These sweet, chewy peanut butter bars are a great no-fuss treat to bring to a potluck or bake sale. A drizzle of chocolate on top makes for a pretty presentation. —Sharon Smith, Muskegon, Michigan

    Very good! I took pcronk's advice and sprinkled mini chocolate chips on top instead of the topping. Also used butter-flavored shortening.

    Too much shortening. I thought it had trans fat in it!

    This is one of my favorite recipes! It was in the TOH cookbook received as a wedding gift. SO rich but SO good! Love the dense brownie-like texture. I usually don't put the drizzle on.

    Reminds me of the bars that we had in the school cafeteria. Yummy!! Even my hubby liked them and he is picky. Will definitely make for a family get together.

    I made these for a Christmas party this past Saturday. I cut the bars into mini squares and they not only made a great presentation but they were delicious!

    Totally delicious, and I also would make them again using butter instead of margarine. That being said, these bars have half! the calories of the "Make-over Peanut Butter Bars" that were supposed to be better for you. That makes these extra good in my opinion!
