Why you’ll love this recipe
- Large sheet cake, perfect for a crowd
- Extremely versatile – swap out plums for any fruit in season
- The moist cake stores well (freezer-friendly)
- Plums – fresh, destoned plums work best for the cake but you can also use canned plums. Just make sure you’re draining them thoroughly before adding them to the base layer.
- Butter – I recommend using unsalted butter for this cake but if you’re using salted, simply omit the additional salt in this recipe.
- Powdered sugar / icing sugar gives the base layer a fine texture but you can substitute it with granulated sugar as well.
- Vanilla extract – You can alternatively use vanilla essence, sugar, or paste.
Versatile Fruit Cake Recipe
If plums are not in season or you’re struggling to get your hands on some fresh ones, you can substitute them with fresh cherries, apples, pears or apricots.

- Instead of lining the sheet pan with baking paper, you can also grease it with unsalted butter to prevent the cake from sticking to the pan.
- Start by preparing the streusel to give them some time to rest in the fridge. Cooler streusel create a firmer and crunchier crumble layer once baked.
- Make sure your base layer doesn’t have any lumps to create a delicate and even cake layer.
- I said it before but make sure to drain canned plums thoroughly to avoid the cake from becoming soggy.
Generously dust the cake with icing sugar once cooled. Add a dollop of whipped cream or vanilla ice cream when serving for some extra indulgence.
