Direction

- BEAT cake mix, Hellmann's® or Best Foods® Real Mayonnaise, water and eggs 30 seconds in large bowl with electric mixer on low speed. Beat on medium speed, scraping sides occasionally, 2 minutes.
- POUR half the batter into prepared pan. Evenly top with dollops of ¾ cup warmed peanut butter and sprinkle with half the chopped Butterfinger® bars. Cover with remaining batter.
- BAKE 30 minutes or until toothpick inserted in center comes out clean. Cool on wire rack 10 minutes. Unmold onto wire rack, if desired, or keep in pan to cool completely.
