How to Make Pioneer Woman Prune Cake
- Finish: Remove cake from oven and immediately pour warm icing over the top. Let sit to soak and set. Serve warm.
- Prep oven & prunes: Preheat oven to 300°F. Simmer prunes in water for about 8 minutes until tender, then drain and mash them. Set aside.
- Mix wet ingredients: In a large bowl, whisk together eggs, sugar, and oil.
- Combine dry ingredients: In a separate bowl, sift together flour, baking soda, and spices.
- Bring it together: Gradually add the dry mixture to the wet, then stir in the buttermilk and vanilla until just combined.
- Fold in prunes: Gently stir in the mashed prunes—avoid overmixing to keep the cake light.
- Bake: Pour batter into a greased 9×13-inch baking dish. Bake for 35–40 minutes, or until a toothpick comes out clean.
- Make the icing: With 5 minutes left on the cake, simmer icing ingredients in a saucepan over medium heat. Let boil gently (without stirring) for 5–7 minutes, until golden and pourable.

FREQUENTLY ASKED QUESTIONS
- Why is my prune cake dry and crumbly?
Too much flour or overbaking can dry it out. Spoon and level your flour, and don’t skip the buttermilk. - Why does my prune cake have a hard top?
If the oven runs hot or you bake too long, the top can set too quickly. Try lowering the oven rack and monitoring closely. - Why isn’t my cake golden brown?
It may be undercooked or lack enough sugar or eggs, which contribute to browning. - Can I make this prune cake ahead of time?
Absolutely! Bake it the day before and store at room temp. Warm slightly and pour fresh icing before serving for best results. - Can I substitute prunes with another fruit?
Dates or figs work in a pinch, but the classic prune flavor and moisture are key to this cake’s identity.
