Plum Cake with Plum Jam Frosting

I happened across some gorgeous plums. I made jam, we ate a bunch fresh and I made a plum cake. This is an easy cake that is incredibly flavorful and perfect for informal gatherings.

Quick Prep

Because the cake uses melted butter, it means you can get baking quickly. There’s no need to wait for butter to soften. In fact, the longest part of the prep in this cake is going to be the chopping of the plums.

If you decide to make the jam frosting, pull the butter out to soften while the cake bakes and cools.

No Need to Peel

I know that in most fresh summer fruit cakes, recipes call for peeling. I, personally, skip it most of the time. It just feels unnecessary to me. However, if you don’t like the peel by all means remove them.

Any Type of Plums

I used black plums in this cake but any kind you have on hand will work. Red, prune, yellow, etc. Truly use what you’ve got and enjoy it.

Simple Yet Elegant

This is a simple cake but make no mistake that it can easily serve as a delightful birthday cake.

The simple nature of it makes it perfect for potlucks or picnics, too.

Lightly Spiced

I wanted the plums to be the star of this cake. Still a little ginger goes well with plums and so there is just a hint of that in the cake. Skip that ginger completely if desired or go heavier as preferred.

Frosting Options

I had a little extra plum jam and decided to use it in the frosting here. It gives a gorgeous color and extra layer of flavor. A simple vanilla frosting would be delightful as well

However, skipping the frosting is an option.

A dusting of powdered sugar gives a little decoration without requiring any frosting.

Serve with a dollop of fresh whipped cream or a scoop of ice cream instead of frosting for an even quicker dessert.
