Ready In:
1hr 10mins
1 9 x 13 pan




  • Preheat oven to 300 F and grease a 9 x 13 in baking pan.
  • Place prunes in small saucepan, cover with water and bring to a boil; cook until soft and mashable (about 8 min).
  • Drain water and mash prunes (ok to leave some chunks behind), set aside.
  • For cake, mix together flour, baking soda, nutmeg, cinnamon, and allspice.
  • In separate bowl, mix together sugar, eggs, oil, and vanilla.
  • Combine wet and dry ingredients and splash in buttermild.
  • Stir until just combined (will be slightly lumpy).
  • Add mashed prunes.
  • Pour into baking pan and bake at 300 F for 35 to 40 minute.
  • When cake has about 5 min left to bake, make icing: combine butter, baking soda, corn syrup, and vanilla in medium saucepan and stir to combine.
  • Bring to a slow boil over med-high heat.
  • Continue boiling until it turns a light caramel color (5-7 min) -- should be pourable but not firm and sticky.
  • Pull cake out of oven.
  • While cake is still warm, pour icing evenly over top -- work fast, it will soak into cake quickly.
  • Spread to coat evenly and serve immediately.

  1. I'm 82 and my grandmother made this very same cake as Christmas gifts over 65 years ago. Your recipe has much more detailed instructions than her recipe that was hand written. Since I didn't watch her making the cakes, your instructions are so helpful. Thank you for posting this wonderful cake that brings back memories of my grandmother. I will make this again for my family this Christmas, with your directions that will make it even better than I have ever made it.
  2. Made this cake today and it is quite good. It's moist and flavorful, but I'm just not sure about the icing. The cake didn't absorb it as quickly as the recipe mentioned. Not sure if I should have poked holes in the cake or not. We tried it warm out of the oven as directed, but I'm curious to see how it will taste once the icing and cake have cooled. Made for Zaar Chef Alphabet Soup, February, 2014.
  3. I made this recipe for Christmas brunch and he family raved about it. So, I took it to a church breakfast and got raves again. This is a moist flavorful cake. Don't let the prunes put you out. This is a cake to die for.


I am a Colorado ski bum at heart, but am currently stuck in Miami, FL of all places working on my Doctoral degree in physical therapy at UM. I can't wait until I graduate and can get back to the mountains! 2 more years, 2 more years...I love to cook and find it a great way to relax and slow down after classes and I can't wait until I have more free time to be able to do it. I have been in the Air National Guard with Colorado and Florida for the last four years and have been fortunate enough to taste many different foods and stretch my palate. I have lots of recipes waiting to be posted and when I finally get the time I will, so stand by!
