It's plum season! You know, the season between summer peaches and fall apples? Yes, that one! And when it comes to plums, I always have to bake with them at least once. So let me take another bite of this delicious plum coffee cake and tell you why you have to make it too!
I am the first to tell you to enjoy the fruit fresh first and bake with it later. Once I got my fill of this season's plums, I knew I wanted to make the coffee cake that I remember my mom always making. The cake is perfect to enjoy with afternoon tea or to share with friends and neighbors, to spread the sweet joy!
Ingredients:
- dry ingredients: all-purpose flour, sugar, salt, baking powder, and soda;
- wet ingredients: large eggs, vanilla, melted butter (or oil), and buttermilk (or whole milk and a splash of vinegar);
- fresh plums, even if they are still a little firm; wash, pit, and quarter all plums.

- This cake is as easy as they get! All you need to do is whisk the dry ingredients together, mix the wet ingredients, and combine them all. No mixer needed! Whisk until smooth and pour the cake batter into a baking pan.
- Arrange plum quarters on the batter.
- Make the streusel topping and sprinkle it over the cake and plums.
- Bake the cake until golden brown.
Helpful tips!
- streusel topping: I highly recommend making the topping first and placing it in the fridge while you make the cake batter and prepare the plums. The colder it is, the crunchier!
- plums: you can use ripe, soft plums or still firm plums; either way, they will soften during baking.
- butter: in this cake, I used melted butter instead of oil, which made the cake richer in flavor.
- buttermilk: I never buy it in the store because it is just too easy to make my own! Use my buttermilk recipe linked in the recipe box.
Recipe FAQs:
Nope, you can leave the skin on the plums for this recipe. The fruit softens perfectly during baking.
Any stone fruit works well! Peaches, nectarines, apricots, or cherries.
I always store fresh cake on the counter for the first 2 days. After that, I keep the leftovers in a container with a lid in the fridge.
Yes, of course! The streusel in this cake is just an extra fancy addition that adds a crunch and dresses up the cake. You can skip it if you like!
