Easy Plum Poppy Seed Cake – Moist, Fruity, and Perfect for Brunch

There’s something incredibly comforting about baking a cake that fills your kitchen with warm, citrusy aromas and feels as cozy as your favorite sweater. The Plum Poppy Seed Cake is one of those timeless recipes that hits all the right notes—moist, tender crumb, pops of tart juicy plums, and just the right amount of crunch from the poppy seeds. It’s not flashy or complicated, but it delivers big on flavor and charm. Whether you’re baking for a weekend brunch, an afternoon tea, or just need a little something sweet to go with your coffee, this cake rises to the occasion effortlessly.

I first stumbled upon this recipe on a lazy Sunday afternoon, flipping through old recipe clippings while sipping tea. The original was from Taste of Home, and something about the simplicity of it made me want to try it right away. I didn’t have high expectations—just wanted to use up some plums—but that first bite was a revelation. Since then, it’s become a go-to in my baking repertoire. It’s also surprisingly adaptable, which makes it even more lovable. I’ve swapped the fruit, played with spices, even changed up the citrus zest depending on the season, and it always comes out beautifully.

If you’ve never baked with plums before, this is a great place to start. They soften and caramelize in the oven, sinking just slightly into the batter while still holding their shape, which means you get pockets of tart, jammy goodness in every slice. Combined with the tender crumb of the cake and that final dusting of confectioners’ sugar, this dessert feels elegant without being fussy. Trust me, you’ll want to make it more than once.

Why You’ll Love This Recipe

There are so many reasons to fall in love with this Plum Poppy Seed Cake, but let’s start with the most obvious one—it’s incredibly delicious. Each bite offers a lovely combination of moist, citrusy cake and juicy plums, with the satisfying texture of poppy seeds sprinkled throughout. It’s the kind of cake that manages to feel both comforting and special, like something you’d make for your family and proudly serve to guests all at once.

Another thing to appreciate about this recipe is its simplicity. You don’t need any fancy equipment or complicated steps. In fact, it all comes together in just one bowl (aside from mixing the dry and wet ingredients separately first), and it bakes up beautifully in a standard 13×9-inch pan. That makes it perfect for beginner bakers or anyone looking for a low-stress baking project.

If you’re baking for a crowd, this cake is a great choice. It slices neatly, travels well, and keeps for days without drying out. Plus, it has a nostalgic, almost old-world feel to it that makes it feel like a cherished family recipe, even if you’re making it for the first time.

Health Benefits

While cake isn’t typically what comes to mind when you think of healthy eating, this Plum Poppy Seed Cake does have a few redeeming nutritional qualities that make it a smarter choice than many other desserts. Let’s start with the star ingredient: plums.

Plums are rich in antioxidants, particularly polyphenols, which have been shown to reduce inflammation and protect against oxidative stress. They’re also a good source of vitamin C, which supports a healthy immune system, and fiber, which aids digestion and helps maintain blood sugar levels. When baked into this cake, plums offer a burst of natural sweetness and tartness, reducing the need for excessive sugar.

In moderation, this cake is a lovely way to enjoy dessert without going overboard. And if you’re serving it to family or friends, especially kids, it’s nice to know that each slice contains real fruit and nutrient-rich seeds—definitely a win in my book.

Ingredients List

Here’s everything you’ll need to bring this lovely Plum Poppy Seed Cake to life. The ingredients are all pantry staples, so you likely already have most of them on hand.

Dry Ingredients

• 2 cups all-purpose flour: This forms the base of the cake, providing structure and a tender crumb.
• 2 teaspoons baking powder: Ensures the cake rises and becomes fluffy.
• 1 teaspoon ground cinnamon: Adds warmth and enhances the fruity flavor of the plums.
• 1/4 teaspoon salt: Balances the sweetness and brings out the other flavors.

Wet Ingredients

• 1 cup granulated sugar: Sweetens the cake and helps with browning and moisture retention.
• 3 large eggs: Bind the ingredients and provide richness and moisture.
• 3/4 cup canola oil or grapeseed oil: Makes the cake incredibly moist without a heavy texture.
• 1 tablespoon grated orange zest: Brightens the flavor with a citrusy zing.
• 1 teaspoon vanilla extract: Deepens the overall flavor and aroma.

Mix-Ins and Toppings

• 2 tablespoons poppy seeds: Add crunch and a slightly nutty flavor that complements the fruit.
• 4 to 5 ripe plums, pitted and thinly sliced: Provide a tart, juicy contrast to the sweet cake base.
• Confectioners’ sugar, for dusting: Adds a light sweetness and an elegant finish.
• Optional: A pinch of cinnamon to mix with the confectioners’ sugar for extra aroma and flavor.

Step-By-Step Cooking Instructions

Preheat and Prepare the Pan

Begin by preheating your oven to 350°F (175°C). Grease a 13×9-inch baking pan with oil or non-stick spray. You can also line it with parchment paper for easier removal later.

Mix the Wet Ingredients

In a large mixing bowl, beat together the granulated sugar, eggs, and oil. Use an electric mixer or whisk vigorously by hand for about 4 to 5 minutes, until the mixture is light, thick, and fluffy.
Add the grated orange zest and vanilla extract. Stir to combine.

Combine the Dry Ingredients

In a separate medium bowl, whisk together the flour, baking powder, cinnamon, and salt. This step ensures the leavening agents and spices are evenly distributed throughout the batter.

Incorporate Dry into Wet

Gradually fold the dry ingredients into the wet mixture. Use a spatula and mix gently to avoid overmixing. Once mostly combined, add the poppy seeds and stir until everything is incorporated. The batter will be thick but spreadable.

Spread Batter and Add Plums

Pour the batter into your prepared baking pan. Use a spatula to smooth the top evenly.
Now, take your sliced plums and lay them gently over the batter. Arrange them however you like—neat rows or a more rustic, scattered look. Don’t press them in; they’ll naturally settle as the cake bakes.

Bake

Place the pan on the center rack of your oven and bake for 40 to 45 minutes. Start checking at the 40-minute mark. The top should be golden, and a toothpick inserted into the center should come out mostly clean, with just a few crumbs.
Let the cake cool in the pan for at least 15 to 20 minutes before slicing.

Finish with a Dusting

Once the cake is cool, dust the top with confectioners’ sugar. For an extra touch, you can mix in a small pinch of cinnamon with the sugar for a lightly spiced finish.

How to Serve

This cake is lovely on its own, but you can easily dress it up depending on the occasion. Here are some serving suggestions to get you started:

• Warm with tea or coffee: Serve slightly warm for a cozy afternoon treat.
• With whipped cream: A dollop of lightly sweetened whipped cream adds an airy contrast.
• As a brunch dessert: Slice and serve as part of a breakfast spread with fruit and yogurt.

Pairing Suggestions

While the cake is definitely the star, pairing it with the right sides or drinks can elevate the experience.

Beverages

• Herbal tea: Chamomile, rooibos, or citrus-infused blends complement the orange zest and plums.
• Iced tea: Light and refreshing, perfect for summer serving.
• Sparkling water with lemon: Great for a simple and fresh pairing.

Side Pairings

• Fresh fruit salad: Adds brightness and freshness.
• Greek yogurt: Especially nice at breakfast or brunch. Try it with honey and granola.
• Soft cheeses: Mild cheeses like mascarpone or ricotta add creaminess that complements the tart plums.

Storage, Freezing & Reheating Instructions

This cake stores and freezes well, making it a great make-ahead dessert.

Storing

Once completely cooled, store the cake in an airtight container at room temperature for up to 3 days. If your kitchen is especially warm, refrigerate it instead to keep it fresh for up to 1 week.

Freezing

To freeze, first let the cake cool completely. You can freeze it whole or in individual slices.

• For individual portions: Wrap each slice in plastic wrap, then place in a freezer-safe bag or container.
• For a whole cake: Wrap tightly in plastic wrap, then again in aluminum foil. Freeze for up to 3 months.

Reheating

To serve from frozen, allow slices to thaw at room temperature or microwave briefly (about 20–30 seconds).
For larger portions, reheat in a 300°F oven for 10 to 15 minutes, covered with foil to prevent drying.

Common Mistakes to Avoid

Even though this recipe is simple, a few common pitfalls can affect the results. Avoiding these will help ensure a perfect cake every time.

Overmixing the Batter

Overworking the batter can lead to a dense texture. Once the dry ingredients are added, mix just until combined.

Using Overripe Plums

Too-soft plums can release excess moisture, making the cake soggy. Use ripe but firm plums for best results.

Skipping the Zest

Orange zest adds essential brightness. Don’t skip it—it really enhances the overall flavor.

Not Greasing the Pan Properly

Make sure to grease the pan thoroughly or use parchment paper. This ensures the cake doesn’t stick when you remove it.

Pro Tips

Want to take your Plum Poppy Seed Cake to the next level? These tips will help you get the best results every time.

Use Room-Temperature Ingredients

Eggs and oil mix better when they’re not cold. Let your eggs sit out for about 30 minutes before baking.

Add a Sugar Crust

Sprinkle a tablespoon of sugar over the top before baking. It caramelizes in the oven and adds a lovely, crisp finish.

Choose the Right Plums

Red or black plums offer good flavor and color contrast. If you prefer a sweeter cake, opt for red ones.

Try a Bundt Pan

This cake also bakes beautifully in a well-greased Bundt pan for a more decorative presentation. Adjust baking time as needed.

Frequently Asked Questions (FAQs)

Can I use other fruits instead of plums?

Yes, you can substitute plums with other fruits like peaches, nectarines, apples, or even berries. Just keep an eye on moisture levels, especially with juicy fruits like berries.

What if I don’t have poppy seeds?

You can omit them, or replace them with chia seeds or sesame seeds for a slightly different texture and flavor.

Can I make this cake gluten-free?

Absolutely. Use a 1:1 gluten-free flour blend. Just be aware that texture may vary slightly depending on the brand.

Can I make it ahead of time?

Yes. This cake keeps well and tastes great the next day. Store it tightly covered, and reheat or serve at room temperature.

Do I need a mixer?

Not necessarily. You can make this cake by hand with a whisk and spatula, though an electric mixer makes the initial step faster.

Can I reduce the sugar?

You can cut the sugar by 1/4 cup without significantly changing texture. However, reducing more may affect moisture and flavor.

Can I freeze the cake with powdered sugar on top?

Yes, but it may dissolve during thawing. For best results, dust with sugar after reheating.

How do I know when it’s done?

The top should be golden and a toothpick should come out clean or with just a few moist crumbs from the center.

Can I use butter instead of oil?

Yes, but the texture will be slightly different—more cake-like and less moist. Use melted, cooled butter in the same amount.

Can I bake this in a round cake pan?

You can, but you may need two 8-inch rounds. Adjust baking time and check for doneness around 30–35 minutes.
