Apple and Sultana Cake Recipe: Warm Spice Streusel Over Moist Fruit Layers

This apple and sultana cake recipe delivers layers of tender fruit cake with a warm spice streusel that keeps every slice moist for days. The secret lies in perfectly balanced sweetness—tart apples and plump sultanas baked into a rich, spiced batter, topped with a crumbly streusel that caramelizes into golden perfection. I developed this version after years of testing, ensuring the cake stays tender without turning gummy, while the streusel adds just the right amount of texture and warmth.

The beauty of this recipe is in its simplicity—no fancy equipment or complicated techniques, just a few key steps that guarantee moist layers and a streusel that stays crispy without overpowering the fruit.

The apples are gently cooked with cinnamon and nutmeg to enhance their natural sweetness, while the sultanas plump up beautifully, creating pockets of juicy flavor in every bite. Baking time is carefully timed to ensure the cake emerges with a golden crust while staying tender inside.

What makes this cake truly special is how well it satisfies cravings without being overly sweet. The warm spices—cinnamon, nutmeg, and a hint of cardamom—create an aromatic experience that makes your kitchen smell like a cozy autumn bakery.

Each slice offers a perfect balance of moist cake, tender fruit, and crumbly streusel, making it ideal for holidays, potlucks, or just treating yourself to a homemade dessert that tastes like comfort.

Serve it warm with a dusting of powdered sugar or a drizzle of vanilla glaze for extra indulgence. The cake keeps well at room temperature for up to five days, so you can bake one batch and enjoy it all week.

Here’s how to make it—every step is designed to ensure your cake turns out perfectly moist and full of flavor.

Ingredients for apple and sultana cake

Pantry staples plus a few fresh ingredients for that perfect autumn cake.

The apples are the star here—Granny Smith or Honeycrisp work best for that tart bite. I always grab mine from the produce section at Whole Foods when they're in season, but any grocery store's apple bin works too. Look for firm ones with no bruises. The sultanas? Soak them in warm water for 10 minutes before adding to the batter—they plump up beautifully and add that juicy pop. For the streusel, Trader Joe's has the best pre-chopped walnuts, but any store's bulk section will do. Toast them first for extra flavor—just 3-4 minutes in a dry pan until fragrant.

No Granny Smith apples? Fuji or Pink Lady hold up well too. Short on sultanas? Raisins at half the amount work in a pinch, but they're less sweet. The oats for the streusel can be any kind—old-fashioned, quick, or even steel-cut if you pulse them in a food processor. Want more crunch? Add an extra 0.25 cup chopped pecans. The cardamom is optional but adds that cozy autumn spice—skip it if you don't have it, but don't replace it with anything else. The baking soda and nutmeg are non-negotiable for that perfect tender crumb and warm spice aroma.

This cake keeps incredibly well—5 days at room temperature wrapped in foil, or 2 weeks in the fridge for even better flavor. I like to slice it and freeze portions between parchment paper for 3 months. The streusel stays crispy if you store it in an airtight container separately. For serving, dust with powdered sugar or drizzle with a simple vanilla glaze—just mix 0.5 cup powdered sugar with 1 tbsp milk. Warm slices with a scoop of vanilla ice cream? Absolute perfection.

Step-by-step instructions for apple and sultana cake

Here's how to bake a cake that's perfectly moist inside with a crunchy, spiced streusel topping.

Start by peeling, coring, and finely chopping the 2 medium apples into small, even pieces—about ¼-inch cubes. This size ensures they cook through without turning mushy. In a medium bowl, combine the chopped apples with the 1 cup sultanas and toss gently to mix. Set this mixture aside while you prepare the cake batter.

Here's the thing—soaking the sultanas in warm water for 15 minutes before adding them to the apples prevents them from staying dry. Drain them well before mixing, but don't worry about removing all the moisture. A little extra liquid helps keep the cake moist during baking.

In a large mixing bowl, combine the 3 cups all-purpose flour, 1.5 cups granulated sugar, 1 tsp baking soda, 0.5 tsp salt, 2 tsp ground cinnamon, 0.5 tsp ground nutmeg, and 0.25 tsp ground cardamom. Whisk these dry ingredients together until fully blended—you should see no more flour streaks. Sifting them first prevents lumps, but whisking works in a pinch.

In a separate bowl, cream together the 1 cup softened unsalted butter and 0.5 cup packed brown sugar until light and fluffy—about 3-4 minutes with an electric mixer. Add the 2 whole large eggs, one at a time, mixing well after each addition. Stir in the 1 tbsp vanilla extract until fully incorporated. This step ensures a tender crumb, so don't skip it.

Gradually add the dry ingredients to the wet mixture, mixing on low speed just until combined. Fold in the prepared apple-sultana mixture, being careful not to overmix. The batter should be thick but pourable. If it looks too stiff, add 1-2 tablespoons of milk to loosen it slightly.

In a small bowl, combine the 1 cup old-fashioned oats, 0.5 cup light brown sugar, 0.5 cup chopped walnuts, and the remaining 2 tsp ground cinnamon. Pulse in a food processor for 10 seconds to break up any large oat clusters, or simply mix with a fork if you prefer a rustic texture. The goal is to create a coarse, crumbly topping that will add texture and flavor.

This is where the magic happens—the streusel should be just crumbly enough to stick together when pressed, but not so fine that it turns into a paste. If it feels too dry, add 1 tablespoon of cold butter and mix until evenly distributed. The butter helps bind the streusel and adds richness to the topping.

Preheat your oven to 350°F and grease an 8-inch round cake pan or line it with parchment paper. Pour half of the cake batter into the prepared pan, spreading it evenly. Sprinkle half of the streusel mixture over the batter, pressing down lightly with your fingers. This ensures the streusel bakes evenly and doesn't just sink to the bottom.

Add the remaining batter, then top with the rest of the streusel. Gently press down again to create a uniform layer. Bake for 45-50 minutes, or until a toothpick inserted into the center comes out clean. The edges should be golden brown, and the top should look slightly cracked—this is normal and indicates a moist cake.

Remove the cake from the oven and let it cool in the pan for 10 minutes. This step is crucial—it prevents the cake from collapsing as it sets. Transfer it to a wire rack to cool completely. Once cooled, dust the top generously with 2 tbsp powdered sugar for a sweet finish.

Slice into 8 equal wedges and serve warm for the best texture—moist layers with a crunchy, fragrant streusel on top. Store leftovers in an airtight container at room temperature for up to 3 days, or refrigerate for up to 5 days. Reheat slices in the microwave for 10 seconds to restore freshness.

Dietary considerations for this dish

Gluten-Free Adaptation

Swap the 3 cups all-purpose flour for a 1:1 gluten-free baking blend like King Arthur Measure for Measure or Bob's Red Mill. Add 1 tsp xanthan gum if your blend doesn't include it—this prevents crumbling.

For extra moisture, replace 2 tbsp of the flour with 2 tbsp ground almond flour. The streusel stays the same, but use gluten-free oats if needed. 🌾
