Steps

  • 2
    In large bowl, beat cake mix, oil, peanut butter and eggs with electric mixer on low speed until smooth. Spread in pan.
  • 3
    Bake 40 to 45 minutes or until toothpick inserted halfway between edge of pan and center comes out with just a few moist crumbs attached. Cool completely on cooling rack, about 1 hour.
