Almond Plum Cake Recipe: Buttery Almond Swirl with Plum Jam Bursts

This almond plum cake recipe delivers a perfect balance of buttery richness and fruity bursts that make every slice unforgettable. The secret lies in a swirl of almond-infused batter wrapped around velvety plum jam, creating layers of texture and flavor that bake into golden perfection. I developed this recipe after years of testing—each element designed to ensure moist crumb, tender almond notes, and jam that stays vibrant, not soggy.

The foundation starts with a simple yet precise method: mixing almond flour into the batter for nutty depth while keeping the crumb light. A 350°F oven ensures even baking, and the cake emerges with a crackly top and tender interior, where the jam pockets release their sweet-tart essence with every bite. This isn’t just dessert—it’s a showstopper that pairs beautifully with vanilla ice cream or a dusting of powdered sugar for an elegant finish.

What sets this recipe apart is its versatility. Serve it fresh from the oven for warm, gooey jam bursts or chill it overnight for cleaner slices. The almond flavor shines through without overpowering the plum’s natural sweetness, making it ideal for brunch gatherings, holiday desserts, or a special treat. The 1-hour baking time (including cooling) ensures you’ll have a crowd-pleasing centerpiece without spending all day in the kitchen.

For an extra touch, garnish with fresh plums or a sprinkle of toasted almonds—though honestly, the cake stands stunning on its own. The key to success? Don’t overmix the batter, and let the jam set slightly before swirling. Trust me, this recipe delivers restaurant-quality results with minimal fuss. Let’s get baking!

Ingredients for almond plum cake

Buttery almond flour and velvety plum jam create layers of flavor in this elegant dessert.

The almond flour gives this cake its signature nutty depth, so buy the finest quality you can find—Bob's Red Mill or King Arthur brands work beautifully. For the plum jam, look for unsweetened varieties at specialty stores or make your own with fresh plums. The jam should be thick enough to hold its shape when swirled but still spreadable. If you're using store-bought jam, check the sugar content—some brands add excessive sweetness that can overpower the cake's delicate balance. For the almonds, toast them yourself in a dry pan for about 3 minutes until fragrant—they'll add a lovely crunch to both the batter and garnish.

No almond flour? Substitute with a blend of 1/2 cup ground almonds and 1/2 cup all-purpose flour, but expect a slightly denser texture. Running short on plum jam? High-quality apricot or raspberry jam works well, though the flavor profile will differ. If your jam is too runny, simmer it uncovered for 5-10 minutes to thicken it slightly. For the butter, European-style unsalted butter like Plugrá adds extra richness, but regular unsalted butter will work fine. The vanilla extract should be pure—imitation extracts often contain alcohol and lack the depth of real vanilla. If you're feeling adventurous, infuse your own vanilla by splitting vanilla beans and steeping them in vodka for a month.

This cake keeps beautifully for 3 days at room temperature wrapped in plastic, though it's best enjoyed within the first 24 hours for maximum jam freshness. For longer storage, refrigerate for up to 1 week or freeze for 3 months. To reheat, warm slices in a 350°F oven for 5-10 minutes to revive the jam's gooey texture. I always bake an extra cake—it disappears quickly, especially when served with vanilla ice cream. The cake freezes particularly well, making it perfect for holiday gifts or last-minute dessert needs. Just thaw at room temperature before serving.

Step-by-step instructions for almond plum cake

This method delivers a perfectly balanced cake with tender layers, buttery almond swirls, and bursts of plum jam.

In a medium bowl, whisk together the 1.5 cups all-purpose flour, 1 cup almond flour, 1.5 cups granulated sugar, 1 tsp baking powder, and 0.5 tsp salt. Sift the dry ingredients together to ensure a light, airy texture—this prevents dense pockets in the final cake. Set aside.

In a separate large bowl, cream the 1 cup unsalted butter and 2 whole large eggs together on medium speed until light and fluffy, about 3-4 minutes. This step incorporates air, which creates the signature tender crumb. Scrape down the sides of the bowl once to ensure even mixing. Add the 1 tbsp vanilla extract and mix for another 30 seconds until fully combined.

Gradually add the dry ingredients to the butter mixture in 3 parts, mixing on low speed after each addition until just combined. Avoid overmixing—stop as soon as the flour disappears. The batter should be thick but smooth, resembling cookie dough. If it appears too dry, add 1 tablespoon of cold water to help bind it.

Divide the batter evenly into two 8-inch round cake pans lined with parchment paper and greased lightly with butter. Spread each layer evenly using an offset spatula. Bake at 350°F for 18-20 minutes, or until a toothpick inserted into the center comes out clean. Let the layers cool in the pans for 10 minutes before transferring to a wire rack to cool completely.

While the cake layers cool, warm the 1.5 cups plum jam in a small saucepan over low heat for 2-3 minutes, stirring occasionally until it reaches a spreadable consistency. Avoid boiling—this prevents the jam from becoming grainy. Remove from heat and let it cool slightly for 5 minutes to thicken further.

Pit the 4 whole fresh plums (if using) and slice them into ¼-inch thick rounds. Arrange half of the plum slices on top of one cake layer, followed by ⅓ of the warm plum jam. Repeat with the second cake layer and remaining plum slices and jam. This creates the signature jam bursts throughout the cake.

Place the second cake layer on top of the first, pressing gently to create a clean edge. Spread the remaining ⅓ cup plum jam evenly over the top layer. Use a sharp serrated knife to cut 6-8 equal wedges into the cake, starting from the center and working outward. Rotate the cake 45 degrees between each cut to create even swirls.

Gently press down on each wedge to encourage the jam to seep into the layers. This technique ensures every bite delivers that signature plum flavor. Sprinkle the top evenly with 0.5 cup toasted sliced almonds for added texture and visual appeal.

Lightly dust the entire cake with the 0.25 cup powdered sugar using a fine-mesh sieve. This creates an elegant finish while complementing the buttery richness of the cake. Let the cake rest for 1 hour at room temperature before slicing—this allows the layers to fully set and the flavors to meld.

Serve at room temperature for the best texture. Each slice should reveal tender layers, bursts of plum jam, and a delicate almond flavor that balances the sweetness. Store any leftovers in an airtight container at room temperature for up to 3 days or refrigerate for up to 5 days. For best results, bring refrigerated cake to room temperature before serving.

Pro cooking tips for this recipe

Batter Consistency

Stop mixing the moment the flour disappears—overmixing develops gluten and creates a tough cake. I use a hand mixer on low speed and scrape the bowl after each addition to prevent dry pockets. If your batter looks too dry, add 1 tablespoon cold water to help bind it without altering flavor. The ideal texture resembles thick cookie dough, not pancake batter. 🥄

Jam Thickness Matters

Your plum jam should be spreadable but not runny—thick enough to hold its shape when swirled. If using store-bought jam, check the sugar content; overly sweet varieties can overpower the cake. For homemade jam, simmer it uncovered for 5-10 minutes to thicken if needed. Cool slightly before assembling to prevent melting the cake layers.

Even Baking Key

Bake both cake layers at 350°F for exactly 18-20 minutes—no longer, or they'll dry out. I rotate the pans halfway through for even browning. Let layers cool in the pans for 10 minutes before transferring to a rack; this prevents cracking. Use a toothpick test—it should come out clean, but not wet with jam.

Swirling Technique

For perfect swirls, cut 6-8 equal wedges from the center outward, rotating the cake 45 degrees between each cut. Press gently on each wedge to encourage jam seepage into the layers. This creates those signature jam bursts in every bite. Work quickly to avoid smudging the jam before the cake sets.

Almond Toasting Tip

Toast your sliced almonds in a dry skillet over medium heat for 3-4 minutes until fragrant and golden. This enhances their flavor and prevents them from becoming soggy when sprinkled on top. Let them cool completely before using—they'll crisp up again when the cake comes out of the oven.

Resting Time Crucial

Never slice the cake immediately after assembling—rest it for 1 hour at room temperature. This allows the jam to fully set and the layers to adhere properly. I place it on a wire rack to ensure air circulation. Patience here prevents messy crumbs and ensures clean slices every time. ✨
