Apple And Plum Cake Recipe: Fruit-Infused Layers With Spiced Streusel Top

This apple and plum cake recipe delivers layers of tender fruit-infused cake with a warm spiced streusel topping that smells like autumn in every bite. The secret lies in baking the fruit until tender but still holding its shape—no mushy cake here. I developed this recipe after years of testing, balancing sweetness between tart plums and crisp apples while keeping the crumb moist without being dense.

The cake features a simple yet effective technique: thinly slicing the fruit and baking it directly into the cake batter, which infuses flavor without making the texture heavy. A buttery streusel topping studded with cinnamon and nuts adds texture contrast and that irresistible crunch. The result? A dessert that's elegant enough for gatherings but simple enough for weeknight baking.

What you'll achieve is a cake with perfectly balanced layers—tender fruit-infused cake beneath a caramelized streusel that holds its shape beautifully. The aroma alone will have everyone gathering around your kitchen. Serve warm with vanilla ice cream or a dollop of whipped cream for the ultimate comfort dessert.

This recipe scales perfectly for special occasions or everyday indulgence, with adjustments for smaller batches or larger crowds. The key to success is precise fruit preparation and proper baking times, which I'll walk you through in the instructions. Let's get baking!

Ingredients for apple and plum cake

Fifteen ingredients for a cake that smells like autumn and tastes like comfort.

The apples and plums are the stars here—Honeycrisp apples for sweetness and Damson plums for tartness create the perfect balance. Grab them at Whole Foods or your local farmers market in late summer and early fall for peak flavor. If you can't find Damson plums, Italian prunes work beautifully too. Thinly slice the fruit (about 1/8-inch thick) and toss with a teaspoon of flour to prevent browning while you prep the rest. The oats and walnuts for the streusel should be toasted lightly before blending—this deepens their flavor and adds that nutty crunch everyone loves.

No Honeycrisp apples? Gala or Fuji are solid substitutes. Plums too tart? Mix in a few extra apples or add a pinch of sugar to the fruit. Running short on walnuts? Pecans or almonds work just as well. For the streusel, if you don't have a food processor, pulse the oats in a blender with the butter until you get a coarse crumb. The milk in the cake batter can be swapped for buttermilk or almond milk if needed—just keep the same total volume. And if you're feeling fancy, infuse the milk with a cinnamon stick while it warms up for extra depth of flavor.

Store the cake in an airtight container at room temperature for up to 3 days—it actually tastes better the next day as the flavors meld. For longer storage, wrap tightly and refrigerate for up to 1 week, or freeze for 3 months. I like to slice it into thick wedges and freeze them individually on a tray before transferring to a bag. Reheat slices in the oven at 350°F for 5-10 minutes to restore that fresh-baked aroma. The streusel topping keeps beautifully, so you can even make it ahead and store it separately until ready to bake.

Step-by-step instructions for fruit-infused apple and plum cake

Layering technique and precise baking times create the perfect balance of tender crumb and spiced fruit.

Peel, core, and slice the 2 lb apples and 1.5 lb plums into ¼-inch thick pieces. Toss them together in a large bowl with 1 tablespoon of the granulated sugar and 1 teaspoon of the vanilla extract. Let them sit for 10 minutes while you prepare the batter—this draws out their juices and intensifies their natural sweetness.

Use a fine-mesh strainer to drain any excess liquid, but don't press the fruit—you want to preserve its texture. The filling should be moist but not soupy. This step ensures your cake stays tender rather than soggy, while still delivering that burst of fruit flavor in every bite.

In a large mixing bowl, whisk together the 3 cups all-purpose flour, 2 teaspoons baking powder, 1 tablespoon ground cinnamon, and ½ teaspoon salt. Set this mixture aside. In a separate bowl, cream together the 1 cup unsalted butter (softened but not melted), 1.5 cups granulated sugar, and ½ cup light brown sugar on medium speed until light and fluffy—about 3-4 minutes. This step incorporates air, which creates that signature tender crumb.

Add the 2 whole large eggs, one at a time, mixing well after each addition. Scrape down the sides of the bowl, then stir in the ½ cup whole milk and 1 teaspoon vanilla extract. Gradually fold in the dry ingredients until just combined—don't overmix. The batter should be smooth but slightly thick, resembling pancake batter.

Preheat your oven to 350°F and grease two 9-inch round cake pans (or use parchment rounds). Divide the prepared fruit filling evenly between the pans. Pour half of the batter over each pan, spreading it evenly with a spatula. Use the back of the spatula to create a slight well in the center of each layer—this helps the fruit distribute evenly.

Sprinkle half of the remaining batter over each layer, then gently press down to create a second thin layer. This technique creates a marbled effect with fruit pockets throughout. The key is to work quickly—once the batter touches the fruit, it begins to set.

In a food processor, pulse the 1 cup old-fashioned oats until they resemble coarse flour. Transfer to a bowl and mix with the ½ cup chopped walnuts, remaining ½ cup granulated sugar, and 1 tablespoon ground cinnamon. Cut in the 1 cup cold unsalted butter (still cubed) using a pastry cutter or your fingers until the mixture resembles coarse crumbs with some pea-sized butter pieces remaining.

Sprinkle the streusel evenly over both cake layers, pressing down gently to ensure good contact. The butter in the streusel will melt and create a caramelized, crisp topping. Bake for 45-50 minutes or until a toothpick inserted into the center comes out clean. Rotate the pans halfway through baking for even browning.

Allow the cakes to cool in their pans for 15 minutes, then transfer to a wire rack to cool completely. This resting period prevents the layers from shifting as they set. For the best texture, serve at room temperature—this lets the flavors meld and the streusel firm up slightly.

The finished cake should have a golden-brown streusel topping with visible fruit pockets throughout. Each slice should reveal layers of tender cake, juicy fruit, and crisp streusel. Store leftovers in an airtight container for up to 3 days or freeze for 2 months. The flavors actually improve as the cake sits, making it even more delicious the next day.

Creative variations of this dish

Spiced Rum Variation

Add a boozy twist by infusing 2 tablespoons dark rum into the cake batter while mixing the wet ingredients. For extra depth, simmer ½ cup rum with the fruit filling before assembling the layers. The alcohol cooks off during baking, leaving behind warm caramelized notes that complement the fruit beautifully. Serve with a dusting of powdered sugar and a drizzle of rum caramel sauce for a sophisticated dessert. 🍷

Citrus-Zest Twist

Brighten the flavor profile by adding 1 teaspoon lemon zest and ½ teaspoon orange zest to the cake batter. The citrus pairs wonderfully with the fruit filling, adding a refreshing contrast to the warm spices. For an extra pop, top the finished cake with a glaze made from ½ cup powdered sugar and 2 tablespoons orange juice. This variation works especially well in spring or summer when citrus is at its peak.

Nut-Free Streusel

Skip the walnuts and replace them with ½ cup toasted coconut flakes or ½ cup chopped dried apricots for a nut-free streusel. The coconut adds a tropical vibe, while the apricots deepen the fruit flavor. For texture, pulse ¼ cup almond flour into the oat mixture instead of blending the oats. This variation is perfect for those with nut allergies or preferences. 🥥

Carrot Cake Fusion

Blend the classic flavors by adding 1 cup grated carrots to the fruit filling and 1 teaspoon ground ginger to the cake batter. The carrots add moisture and natural sweetness, while the ginger enhances the spiced notes. Top with a streusel that includes ½ cup chopped pecans for a Southern-inspired twist. This variation is a crowd-pleaser with a familiar yet unexpected flavor profile.

Gluten-Free Adaptation

Replace the all-purpose flour with a 1:1 gluten-free baking flour blend like Bob's Red Mill or King Arthur. For extra moisture, add 2 tablespoons ground flaxseed mixed with 3 tablespoons water to the wet ingredients. The streusel can remain the same, but use certified gluten-free oats to avoid cross-contamination. This version maintains the same tender texture and rich flavor while being safe for gluten-sensitive guests.

Seasonal Berry Boost

In late summer, swap the plums for 1.5 lb fresh blackberries or raspberries and reduce the apples to 1 lb. The berries add a vibrant color and juicy burst that pairs wonderfully with the apples. For the streusel, add 1 teaspoon ground cardamom to complement the berries' tartness. This variation is perfect for summer gatherings and brings a fresh, fruity twist to the classic cake. 🍓
