I clipped this easy peanut butter cake recipe from a newspaper years ago. The house smells fantastic while it's slow cooking. My husband and son enjoy the cake with ice cream and nuts on top. —Bonnie Evans, Norcross, Georgia

Test Kitchen Tips
  • If you want a little extra crunch, feel free to swap out creamy peanut butter for crunchy!
  • Canola oil is high in monounsaturated fat, a type that helps to decrease blood cholesterol levels, and low in saturated fat, which can increase blood cholesterol. Olive oil would also taste great in this recipe and has the same healthy-fat properties.
  • Peanut butter lovers can't get enough of these creamy recipes.
  • Peanut Butter-Reduced fat/Generic
    Reduced-fat peanut butter is not recommended for this recipe.
