Plum Cake You’ll Want to Make Time and Again
This post may contain affiliate links. Please read our disclosure policy.
This is a Plum Cake recipe you’ll want to make again and again. I have… and do, beginning in September and for as long as fresh plums appear in my market.

For me, the arrival of plums signals the beginning of fall. The transition from hot summer days into the cozy, cooler days of autumn. Days of brilliantly colored leaves, nips in the air, and savory foods cooking in my kitchen.
A season I wait for all year long for.
And yes… it often begins… and even ends… with a plum cake.
This simple-to-make, beautifully fresh plum cake is one to keep, share, and most definitely make.
Plum Cake Ingredients
This simple cake requires equally simple ingredients you likely have on hand, except maybe the plums. The exact measurements are in the recipe card at the bottom of this post.
- All-purpose flour
- Baking powder
- Ground cinnamon
- Ground cardamom
- Butter (1 stick, 8 tablespoons)
- Granulated sugar
- Large eggs
- Vanilla extract
- Sour cream
- Fresh plums, pitted and sliced
How to Make This One Layer Easy Plum Cake
Preheat the oven to 350°F and grease a 9-inch cake pan. A springform pan works great with this cake!
Step 1: Whisk the Dry Ingredients
In a large bowl, whisk together the flour, baking powder, cinnamon, salt, and cardamom.
Step 2: Cream the Butter and Combine
With an electric or stand mixer, cream together the butter and 1 cup sugar, beating until it is light and fluffy, about 3 minutes. Add the egg, vanilla, and sour cream to the bowl, mix on low speed until just combined. Gradually add the flour mixture to the butter mixture and mix until smooth.
Step 3: Bake
Transfer cake batter to prepared pan. Top with sliced plums and sprinkle 2 tablespoons sugar over the cake top. Bake for 35-40 minutes, or until a tester inserted in the middle comes out clean.
Remove the cake from the oven, run a sharp knife around the edges of the cake while it’s still hot to loosen it from the pan. Let the cake cool completely on a rack. Dust with confectioners’ sugar, slice, and serve with ice cream or whipped cream if desired.

I banged the crap out of this recipe. Wow, had a blast making this cake!!! Easy, peasy to come together and looks great. I added a squeeze of lemon and some zest, as well as turbo sugar on the topping to give it pop. Baked it out and wow! Too good to share. We all have been there, haven’t we? Have to eat this one all by myself. Maybe I can get away with saying “it’s a mistake”, but everyone is already on to that one. Help me, Ms. Stephanie! I need a new excuse to keep this scrumptious treat to myself! LOL. Easy and fun. In the line-up now as a regular fall item because something this good I can also sell. Oh yeah!
Hi, Clint- thank you so much for trying the cake! I’m so glad you enjoyed it— I love it too!
