Spiced Italian Prune-Plum Cake

Directions

1. Preheat your oven to 350°F (175°C). Generously butter and flour a 10-inch Bundt pan, making sure to reach every crevice. Tap out the excess flour. This step a must for a clean release later.
2. Pit and chop the Italian prune plums into bite-sized pieces until you have 2 cups. Set them aside while you mix the batter. No need to cook them first. The oven will soften them into jammy pockets as the cake bakes.
3. In a large bowl, cream the butter and sugar together on medium speed for 4–5 minutes until the mixture turns pale, light, and fluffy. This builds the structure that gives the cake its lift and tender texture.
4. Beat in the eggs one at a time, scraping the bowl after each addition. Continue beating until the mixture looks almost white and billowy. Room-temperature eggs incorporate smoothly and help prevent curdling.
5. In a separate bowl, whisk together the flour, cinnamon, cloves, nutmeg, and baking soda so the spices and leavening are evenly distributed.
6. Add the dry ingredients to the butter mixture in three additions, alternating with the milk. Start and end with the flour. Mix on low speed just until the last streaks disappear. Overmixing at this stage toughens the crumb.
7. Toss the chopped plums with 2 tablespoons of the measured flour (this helps suspend them in the batter instead of letting them sink). Gently fold the floured plums and the chopped walnuts into the thick batter.
8. Spoon the batter into the prepared Bundt pan and smooth the top. Bake for 55–65 minutes, or until the cake begins to pull away from the sides of the pan and a toothpick inserted near the center comes out with just a few moist crumbs.
9. Let the cake cool in the pan for 10–15 minutes. This resting time helps it set so it releases cleanly. Place a cooling rack over the pan, carefully invert, and lift the pan away. Cool the cake completely on the rack before frosting.
10. For the frosting, cream the butter until smooth. Gradually beat in the powdered sugar and cocoa powder. Add the pinch of salt. Stir in the strong coffee a tablespoon at a time until the frosting reaches a soft, spreadable consistency that holds gentle peaks. Beat until light and fluffy, then stir in the vanilla. Spread over the cooled cake.

Quick Adjustments for Regular Plums

Quantity

• Still use 2 cups chopped plums. With larger fruit you’ll only need about 3–4 medium regular plums instead of 8–10 small Italian ones.
• Drain the juice
• After pitting and chopping, place the plums in a colander or fine strainer for 10–15 minutes. Give the colander a gentle shake once or twice. This removes the surface liquid that would otherwise soak into the batter. ### Flour toss Toss the drained plums with 3 tablespoons of the measured flour (instead of 2). The extra flour helps absorb any remaining juice and keeps the pieces from sinking. ### Milk If your plums looked especially juicy or soft, reduce the milk to ⅓ cup instead of ½ cup. You can always add the last tablespoon back if the batter feels too thick.

Peeling (optional but recommended)

Regular plum skins are often thicker than Italian prune plum skins. If the skins feel tough or waxy, peel them.

A fast way: score an X on the bottom of each plum, drop into boiling water for 20–30 seconds, then slip the skins off under cool water. If the skins are thin and tender, you can leave them on for color and flavor.

Sugar

Taste a piece of your chopped plum. If it’s quite tart, add an extra 1 tablespoon of sugar to the batter. No need if the plums are already sweet.

Baking time

Start checking at 55 minutes as before, but expect it may need the full 60–65 minutes (or even 5 minutes longer) because of the extra moisture. The cake is done when it pulls away from the sides and a toothpick comes out with just a few moist crumbs.

What to Expect

The cake will still be fragrant with warm spices and studded with soft fruit, but the plum pieces will break down a little more and the crumb will be slightly moister and jammier. The walnuts and mocha-cocoa frosting will balance everything perfectly. Many home bakers make this exact swap and love the result. You’re still going to have a gorgeous fall Bundt that smells like heaven while it bakes. Go ahead and make it with what you have — just drain, flour-toss, and adjust the milk if needed. It’ll turn out wonderful. Let me know how it goes or if you want a tiny tweak once you see your plums!
