Family-Favorite Peanut Butter Cake

My grandmother and aunts made this for family gatherings to go along with fresh homemade ice cream. I now share it with my family and friends during special gatherings. —Keith Gable, Goddard, Kansas

    I made this cake today and it was awesome. I will definitely make again. I substituted the buttermilk for 2% milk and it still came out great. And my kids love it:)

    I wouldn't rate it as healthy or diabetic friendly, but it sounds very tasty.....I might try it for a church fellowship, that way we can enjoy a piece and the rest will be enjoyed by others.
