Laura’s Old Fashioned Prune Cake with dried plums and a buttermilk glaze comes from a cherished family heirloom recipe.
Laura’s Old-Fashioned Prune Cake
by Sue Lau | Palatable Pastime
One of the favorite family get-together recipes from extended family when I was growing up as a child came from my cousin Sandy Payne, who received the recipe from her mother, Laura Wyatt, and in time, passed it along to her own daughter, Lisa Walton.
It was a much guarded secret for many years but has since found its way into daylight for all to now enjoy.
And if you think you might not enjoy it when you hear the word “prune” you might be amazed after the first bite. While prunes bring to mind images of old grandmothers coaxing their grandchildren to eat large wrinkled dry fruits for their better health, nothing could be further from the truth.
In fact, prune cake is more like an old-fashioned spice cake with nuts and raisins, even if the raisins are slightly different. It is like a dessert version of raisin bread, something all of us, I imagine, enjoyed as children, even with our grandparent’s approval.
With fond memories we can look back to our grandparents as well, remember all sorts of old-time recipes such as fudge, molasses crinkles, salt-water taffy, raisin bread, and even prune cake. What are your favorite memories with your grandparents? Join me Sunday evening at 7 est on twitter for a great chat involving this very subject. #SundaySupper
And on a sad note, it is sad indeed that this very day, another of Lisa’s grandparents has passed away and her heart has that deep ache. Again, it will be memories which fill the emptiness and make her whole again. My own grandparents have been gone for many years, but I still think of them and the foods they shared. My grandfather Alfred and I always could agree on the sheer awesomeness of a baby coke in a 6 ounce bottle. It just tasted different!
I think he would have liked this prune cake as well, even though it hails from different sides of the family. I know I always enjoyed eating it and will treasure the recipe (Thanks Lisa for sharing it!). And as for sharing recipes, the Sunday Supper group has shared a boat load of their favorite recipes to help celebrate Grandparent’s Day. Check out the links below and be sure to pin all your personal favs.

Sounds so yummy. Thank you.
Thanks!
This is just what I have been looking for ! My mom used to make a prune cake for special occasions and the recipe was lost somehow after she passed. .I will be thinking of her when I make and share this one! Thanks
Thanks!
I love prunes, but then again I am old. I probably just wouldn’t mention to my kids, greats and grands that there are prunes in it LOL. It looks deliciously moist and the perfect accompaniment to a cup of morning coffee.
It does taste like raisins…and kids like oatmeal raisin cookies, right? There is some strange phobia surrounding prunes that can be worked out with just one bite! LOL Thanks, Wendy!
I have no problem with prunes, and this recipe looks great! Food creates such wonderful memories.
Thanks!
What a lovely cake, Sue. I have no qualms eating prunes—they must add a delicious sweetness and moistness to this sweet treat.
Thanks Liz! Tastes like raisins in there!
Lovely cake and recipe! My mother-in-law makes a prune tart this time of year and your post reminded me of it! It’s delicious, but sometimes people get ideas in their heads about prunes and there is no changing their minds. 😉
Not sure why—doesn’t taste much different than having raisins in oatmeal raisin cookies. Baking with prunes (plums) is not the same as eating one out of the box, but I do know what you mean about those food phobias! My husnad likes hamantaschen with prunes and also kringles. I think all of them are excellent!
The dessert version of raisin bread? Yes please! Looks like a lovely cake.
It looks wet—but that is the shine of a perfect glaze. But moist inside!
I am marking this one to try Sue! It reminds me of something my own grandmother made and I haven’t found that recipe. I’m sorry to hear of yet another loss in the family. Your post is lovely and your story very sweet. Memories are wonderful, aren’t they?
Thanks. I am glad you are trying the recipe! It is very good and very well received.
I’ve never tried a prune cake but it sounds incredible! I love all the goodies in it!
Thanks! It’s very good, similar to an applesauce cake or pumpkin bread
Hi Sue — you are right, I would not have thought “prunes” but this looks great — cathy from Delaware Girl Eats
Thank you!
I love prunes, thanks for another great way to use them!
I’m happy to share the recipe!
Looks like ooey gooey deliciousness to me!
My grandmother liked prunes – they were a mandatory component of the Christmas table.
Thank you!
YUM!!! Prunes get such a bad rap, but I love them!
Thanks, COnstance!
Finally, a recipe like my Granny’s……thank you, thank you, thank you
