Plum Cornmeal Cake

A Light and Fluffy Plum Cornmeal Cake for Any Time of Day

This plum cornmeal cake is one of those recipes I turn to when I want something simple that still feels special. The coarse cornmeal gives the crumb a tender, slightly sandy texture that I love, and the tart plums cut through the sweetness just enough. It works for breakfast with a cup of coffee, as a teatime snack, or as a light summer dessert, no fuss, just good.

3 Reasons This Easy Plum Cake Stands Out

• The cornmeal adds a subtle crunch and nutty flavor that pairs perfectly with juicy, tart plums.
• It comes together quickly with a stand mixer, no complicated steps or special techniques.
• The plums are layered both in the middle and on top, so every slice gets fruit in every bite.

Key Ingredients for a Perfect Cornmeal Cake

• Coarse cornmeal, This is what gives the cake its signature texture. Don’t use fine cornmeal or corn flour; the coarse grind adds a pleasant grit. Look for stone-ground cornmeal for the best flavor.
• Plums, Choose ripe but firm plums that hold their shape during baking. Red or black plums work well; avoid overripe ones that turn mushy.
• Buttermilk, Adds tenderness and a slight tang that complements the cornmeal. If you don’t have buttermilk, mix 1/3 cup milk with 1 teaspoon lemon juice and let it sit for 5 minutes.

Kitchen Tools for This Plum Recipe

• 9-inch springform pan, essential for easy release without damaging the cake.
• Stand mixer with paddle attachment, makes creaming butter and sugar quick and even.
• Fine-mesh sieve for sifting dry ingredients.
• Offset spatula for spreading batter evenly.

Tips for Making the Best Plum Cornmeal Cake

I find that choosing ripe but firm plums makes a big difference. If they’re too soft, they’ll turn mushy during baking and make the cake soggy. Look for plums that give slightly when pressed but still hold their shape. When you sift the dry ingredients, don’t skip it, it aerates the flour and ensures the baking powder is evenly distributed, which helps the cake rise evenly.

For the cornmeal sprinkle on top, I use the same coarse cornmeal from the batter. That little extra crunch on the crust is a nice contrast to the tender crumb. And when you test for doneness, insert a toothpick into the center of the cake, not into a plum piece, which will be wet. If it comes out clean or with a few dry crumbs, it’s done.

How to Layer Plums in This Cornmeal Cake

I spread about half the batter in the pan, then arrange half the plum pieces over it. This middle layer ensures every slice gets fruit, not just the top. After adding the remaining batter, I place the rest of the plums on top, pressing them in just slightly so they stay put. The final sprinkle of cornmeal and turbinado sugar gives the top a crunchy, sparkly finish. Don’t worry if some plums sink a little, that’s part of the charm.

Plum Cornmeal Cake Variations to Try

If you don’t have plums, this cake works well with other stone fruits. I’ve tried nectarines and apricots, both hold up nicely and offer a similar tart-sweet balance. For a brighter flavor, add a teaspoon of lemon zest to the batter along with the vanilla. You can also swap half the all-purpose flour for whole wheat pastry flour for a slightly nuttier, more wholesome crumb. For a dairy-free version, use a plant-based butter and make a quick buttermilk by mixing 1/3 cup of your favorite milk with 1 teaspoon of lemon juice, then let it sit for 5 minutes.

How to Serve This Tart Plum Cake

I like to serve this cake slightly warm or at room temperature. A dollop of lightly sweetened whipped cream or a scoop of vanilla ice cream balances the tartness of the plums beautifully. For a simpler finish, a dusting of powdered sugar right before serving adds a pretty touch. It’s also excellent on its own with a cup of black tea or coffee, the cornmeal flavor really shines.

How to Store Leftover Plum Cornmeal Cake

Store the cake in an airtight container at room temperature for up to 2 days. If you need it to last longer, refrigerate it for up to 5 days. I recommend bringing refrigerated slices back to room temperature before serving, the texture is much better that way.

Can You Freeze Plum Cornmeal Cake?

Yes, this cake freezes well. Let it cool completely, then wrap it tightly in plastic wrap followed by a layer of aluminum foil. Freeze for up to 3 months. To thaw, move the wrapped cake to the refrigerator overnight. For the best texture, warm individual slices in a 300°F oven for 5 to 10 minutes before serving.

Best Ways to Reheat Plum Cornmeal Cake

I prefer reheating slices in a toaster oven or regular oven at 300°F for 5 to 7 minutes. This restores the slight crispness on the edges without drying out the cake. The microwave works in a pinch, but it softens the cornmeal texture, still tasty, just not as nice.
