Apple and Sultana Cake Recipe: Buttery Streusel Crown Over Spiced Fruit Layers

This apple and sultana cake recipe delivers a perfect balance of tender spiced fruit layers topped with a buttery, crumbly streusel crown that begs for seconds. 🍏 The secret lies in the slow-cooked apple filling—sweetened just enough to caramelize while keeping the texture moist—paired with plump sultanas that soak up the warm spices. I developed this version after years of baking apple cakes that either turned out too dry or too soggy, and this method finally cracked the code for foolproof results every time.

The beauty of this recipe is how it combines classic comfort with professional techniques you can easily master at home. You'll start with a simple cake base infused with cinnamon and nutmeg, then layer it with the spiced apple-sultana filling that bakes until tender but still holds its shape. The streusel topping—made with just butter, flour, and brown sugar—transforms into a golden, crunchy crown that contrasts perfectly with the soft layers below.

What you'll end up with is a cake that's rich with apple flavor, studded with sweet sultanas, and crowned with buttery crumbs that stay crisp even after slicing. The warm spices create a cozy aroma that fills your kitchen, while the texture delivers a satisfying mix of tender cake, jammy fruit, and crunchy topping in every bite. This is the kind of dessert that feels special enough for company but simple enough for a weeknight treat.

The best part? This recipe scales beautifully—whether you're baking for a family gathering or just want to enjoy a slice with afternoon tea. The instructions are designed to be beginner-friendly, with clear steps and timing that ensure success. Let's get started on creating this timeless classic that always disappears too quickly.

Ingredients for apple and sultana cake

Here's what you need for a cake that balances tender spiced fruit layers with a buttery streusel crown.

The apples are the heart of this cake—Granny Smith or Honeycrisp hold up best during baking. Your grocery store's produce section usually has these, but if you're feeling fancy, hit up a specialty market for Braeburns. They're sweeter and more aromatic. Peeled and diced into even 1/2-inch pieces, they'll caramelize beautifully without turning mushy. The sultanas? Trader Joe's has the best plump ones—avoid those sad, shriveled raisins. Soak them in warm water for 10 minutes before adding to the filling, then drain well. That extra moisture makes all the difference in texture.

No Granny Smith? McIntosh or Fuji work in a pinch, but they'll break down faster. Running out of vanilla? Almond extract at half the amount gives a different but delicious twist. The streusel topping is where you can get creative—swap half the flour for crushed graham crackers or old-fashioned oats for a different texture. And if you're out of brown sugar, white sugar plus 1/4 tsp molasses mimics that caramelized flavor. The butter for the streusel needs to stay cold—cut it into small cubes and keep it in the fridge until you're ready to mix.

This cake keeps beautifully for 5 days in an airtight container at room temperature, though I find it's best enjoyed fresh. The streusel topping stays crisp for about 3 days before softening slightly. For longer storage, wrap tightly in plastic and refrigerate—it'll last 1 week. Freezing? Wrap individual slices in plastic and freeze for up to 3 months. Just let them sit at room temperature for 10 minutes before serving. And trust me on this—the first slice is always the best. Make extra.

Step-by-step instructions for apple and sultana cake

Here's how to bake a moist, spiced cake with juicy apple layers and a buttery streusel crown.

Peel, core, and dice the 4 medium apples into ¼-inch pieces—smaller pieces will soften faster and release more juice. Toss them with the 1.5 cups sultanas and 2 tbsp lemon juice in a large bowl. The lemon juice prevents browning and brightens the flavors.

Let the mixture sit for 10 minutes while you prepare the batter. This gives the sultanas time to plump up and the apples to release some juices. You'll want the filling to be moist but not soupy when you add it to the cake layers.

Preheat your oven to 350°F and grease an 8-inch round cake pan or line it with parchment paper. In a large mixing bowl, combine the 2.5 cups all-purpose flour, 2 tsp baking powder, 1.5 tsp ground cinnamon, 0.5 tsp ground nutmeg, and 0.5 tsp salt. Sift the dry ingredients together to aerate the flour and prevent lumps.

In a separate bowl, cream together the 1 cup unsalted butter (softened but not melted) with the 1.5 cups granulated sugar and 0.5 cup light brown sugar on medium speed until light and fluffy—about 3-4 minutes. Add the 2 whole large eggs, one at a time, mixing well after each addition. Stir in the 1 tbsp vanilla extract. Gradually fold in the dry ingredients until just combined.

Divide the batter evenly between two 4-inch round cake pans (or use one 8-inch pan if baking in layers). Spoon half of the apple-sultana mixture over the batter in each pan, pressing down gently to distribute it evenly. This ensures every bite has that perfect fruit-to-cake ratio.

Bake for 25-30 minutes, or until a toothpick inserted into the center comes out clean. The cake should be golden on top and spring back when pressed lightly. If baking in layers, bake one layer at a time, then let each layer cool for 10 minutes before assembling.

While the cake bakes, prepare the streusel topping in a small bowl. Cut the 1 cup unsalted butter into small cubes and mix with the 0.5 cup all-purpose flour (streusel) and 0.25 cup packed light brown sugar (streusel). Rub the mixture between your fingers until it resembles coarse crumbs with some pea-sized butter pieces remaining—this creates that perfect crunchy texture.

Once the cake layers are baked and slightly cooled, spread the streusel evenly over the top layer. The butter will melt slightly from the residual heat, creating a golden, caramelized crust. Return the cake to the oven for 5-7 minutes until the streusel is golden brown and bubbly.

Let the cake cool in the pan for 10 minutes, then transfer it to a wire rack to cool completely. This resting time allows the layers to set and the flavors to meld. Serve slices warm or at room temperature—each bite should deliver a perfect balance of tender cake, spiced apples, sweet sultanas, and buttery streusel.

For extra moisture, brush the top with a simple syrup made from equal parts sugar and water, heated until dissolved. Store leftovers in an airtight container for up to 3 days, though I doubt they'll last that long!

Dietary considerations for this apple and sultana cake

Gluten-Free Adaptation

For a gluten-free version, replace the 2.5 cups all-purpose flour with a high-quality blend like King Arthur Gluten-Free Measure for Measure Flour. This 1:1 substitute maintains the cake's structure beautifully. Add 1 tsp xanthan gum to the dry ingredients to improve elasticity. The streusel topping works fine as-is since it uses minimal flour, but for extra binding, mix in 2 tbsp gluten-free oats with the flour. 🌾

Vegetarian-Friendly

This recipe is naturally vegetarian, but if you're using store-bought ingredients, check that your vanilla extract and lemon juice are certified vegan (some extracts contain animal-derived alcohol). For extra richness, replace ½ cup of the butter in the streusel with ½ cup dairy-free margarine like Earth Balance. The flavor won't be compromised, and the texture remains perfect.

Lower Sugar Options

To reduce sugar, swap ½ cup granulated sugar for ½ cup coconut sugar in the cake batter and ¼ cup brown sugar in the streusel for ¼ cup monk fruit sweetener (like Lakanto). These alternatives have lower glycemic indexes without sacrificing sweetness. Reduce the baking time by 3-5 minutes since coconut sugar caramelizes faster. 🍚

Nut-Free Considerations

This recipe is already nut-free, but if you're concerned about cross-contamination, bake the cake on a clean surface and use fresh, unopened packages of all-purpose flour and baking powder. For extra caution, prepare the streusel in a separate bowl that hasn't held nuts before. The sultanas and apples are typically nut-free, but always check packaging labels.

Dairy-Free Version

Replace the 1 cup unsalted butter in both the cake and streusel with 1 cup dairy-free butter like Miyoko's. For the streusel, ensure your brown sugar is refined (some organic sugars contain dairy). The cake will still rise beautifully, and the streusel will maintain its signature crunch. The flavor stays rich and buttery—no one will miss the dairy! 🧈
