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

This apple and sultana cake recipe delivers a perfect balance of moist fruit layers and a fragrant spice streusel topping that makes every slice irresistible. 🍏 The secret lies in tender apples and plump sultanas baked into a rich, buttery cake base, while the streusel adds a delightful crunch that contrasts beautifully with the soft interior.

I've perfected this recipe over years of baking, ensuring it stays moist even days after baking.

The cake begins with a simple yet flavorful batter infused with warm spices like cinnamon and nutmeg, which complement the natural sweetness of the apples and sultanas. These dried fruits absorb the juices during baking, creating pockets of intense flavor in every bite.

The streusel topping, made with rolled oats, brown sugar, and melted butter, caramelizes beautifully, adding texture and depth to each serving.

What you'll achieve is a cake that's rich yet not overly sweet, with a tender crumb and a streusel topping that's crisp enough to hold its shape but soft enough to melt slightly with each bite.

The combination of apple and sultana creates a complex flavor profile that's both comforting and sophisticated, perfect for gatherings or as a special treat for yourself.

This recipe is designed to be straightforward yet impressive, making it ideal for both beginner and experienced bakers. The preparation takes just 30 minutes, with an additional hour of baking time, ensuring you'll have a warm, inviting cake ready to serve.

Serve it with a dollop of whipped cream or a scoop of vanilla ice cream for the ultimate dessert experience.

Ingredients for apple and sultana cake

These 15 ingredients create a moist, spiced cake with perfect fruit layers and crunchy streusel topping—worth every bite!

The apples are non-negotiable—Honeycrisp or Fuji stay juicy while baking. Costco or Trader Joe's usually have them pre-washed and ready to slice. If you can't find fresh, canned apple pie filling works in a pinch (drained well). For sultanas, look for plump, moist ones—the cheap, shriveled kind won't work. I always buy extra because they disappear fast. The rolled oats? Bob's Red Mill is my go-to—they toast beautifully for that perfect streusel crunch.

No cinnamon? Cardamom or pumpkin pie spice adds warmth, but it's different. Short on apples? Substitute with pear slices or even more sultanas (up to 2 cups). The butter in the streusel can be vegetable shortening if you're avoiding dairy, but trust me on the full-fat version. Brown sugar packed vs. scooped matters—press it firmly into the measuring cup. For the cake batter, if you're at elevation, add an extra 0.5 tsp baking powder. And if you're feeling fancy, swap half the flour for almond flour.

This cake keeps beautifully—tightly wrapped at room temp for 2 days, or fridge for 5 days. The streusel gets crunchier over time, which is why it's even better the next day. For freezing, slice first, then wrap each piece in plastic—up to 3 months. I always make two batches because it disappears fast. The leftovers? Toasted with butter and cinnamon make an amazing breakfast treat.

Step-by-step instructions for apple and sultana cake

Here's how to bake this showstopper with layers of spiced apples and sultanas topped with a crunchy streusel.

Start by peeling, coring, and thinly slicing the 4 medium apples into ⅛-inch thick rounds. Toss them in a large bowl with the 1.5 cups sultanas and 1 tablespoon vanilla extract. This pre-soaking step ensures the sultanas plump up and the apples stay juicy during baking. Let this mixture sit for 10 minutes while you prepare the batter.

Real talk: Don't skip the vanilla here—it's what makes the sultanas taste like they've been simmered in spiced syrup. The apples should look glossy and ready to absorb all those wonderful flavors. If you're using tart apples like Granny Smith, a pinch of sugar sprinkled over them now will help balance the acidity later.

Preheat your oven to 350°F and grease a 9-inch round cake pan with butter, then line the bottom with parchment paper. In a separate bowl, whisk together the 2.5 cups all-purpose flour, 2 teaspoons baking powder, 1.5 teaspoons ground cinnamon, 0.5 teaspoon ground nutmeg, and 0.5 teaspoon salt. Sift this dry mixture directly into your mixing bowl to avoid lumps.

In a separate large bowl, cream together the 1 cup unsalted butter and 1.5 cups granulated 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. Scrape down the sides of the bowl, then gradually add the dry ingredients while mixing on low speed just until combined. Fold in the apple-sultana mixture gently with a spatula—just until evenly distributed.

Spread half of the cake batter into your prepared pan, creating an even layer. Spoon the remaining batter on top, then gently swirl a knife through the center to create marbled streaks. This creates beautiful layers when sliced. Press the apple-sultana mixture evenly over the top layer, making sure every bite gets that fruity goodness.

For the streusel topping, combine the 1 cup rolled oats, 0.25 cup light brown sugar, 0.5 teaspoon ground cinnamon, and the remaining 0.5 cup cold cubed butter in your hands or a food processor. Rub the mixture between your fingers until it resembles coarse crumbs with pea-sized butter pieces—this ensures a perfectly crumbly texture. Sprinkle this evenly over the apple layer.

Bake for 45-50 minutes until the top is deep golden brown and a toothpick inserted in the center comes out clean (or with just a few moist crumbs). The cake should spring back slightly when pressed gently in the center. Here's the thing—don't overbake! The cake will continue cooking as it cools, and you want that moist texture promised in the title.

When done, let the cake cool in the pan for 15 minutes before transferring to a wire rack. The streusel will be soft and gooey when hot, but it sets up beautifully as it cools. For extra moisture, you can tent the cake with foil while it cools to prevent the top from drying out. Serve warm with a dollop of whipped cream or a scoop of vanilla ice cream for that ultimate comfort food experience.

Troubleshooting this recipe

Dense Cake Texture

If your cake turns out dense instead of moist, you likely overmixed the batter or packed the dry ingredients too tightly. For the dry mix, gently whisk the flour, baking powder, and spices together—don’t press down with a spoon.

When combining wet and dry ingredients, mix just until combined (about 10-15 seconds on low speed). Overmixing develops gluten, making the cake tough. Also, ensure your butter is room temperature (not melted) for proper emulsification. 💡

Streusel Too Crumbly

The streusel might be too dry if the butter was warmed or if you over-processed the mixture. Use cold cubed butter (straight from the fridge) and rub it into the oats and sugar with your fingers until it resembles pea-sized crumbs.

Avoid using a food processor—it breaks the butter into tiny pieces, making the streusel too fine and crumbly. If it’s already baked, try brushing the top with warm honey or melted butter to add moisture. ✨

Sultanas Not Plump

Shriveled sultanas are usually a sign of old or low-quality fruit. Soak them in warm water for 10-15 minutes before adding to the batter to plump them up.

For extra flavor, soak them in 1 tablespoon warm water + ½ teaspoon vanilla extract—this mimics the syrup-like texture you’d get in a baked dessert. If they’re still dry after baking, sprinkle a little orange juice over them in the pan before adding the streusel. 🍇

Cake Stays Raw Inside

An underbaked center often means the oven wasn’t hot enough or the cake needed more time. Preheat your oven for at least 15 minutes before baking, and use an oven thermometer to confirm it’s at 350°F—many ovens run hot or cold.

If the edges are brown but the center’s wet, tent the cake with foil and bake for another 10 minutes. A toothpick should come out with a few moist crumbs (not wet batter). 🔥

Apples Too Watery

Excess moisture from apples can make the cake soggy. Pat the sliced apples very dry with a paper towel before tossing them with sultanas. If using particularly juicy apples (like Honeycrisp), sprinkle them with 1 teaspoon sugar and let them sit for 5 minutes before mixing with the batter.

This helps absorb some of the liquid. For extra insurance, pre-bake the apple-sultana mixture for 5 minutes at 350°F before adding it to the cake batter. 🍏

Streusel Sticks to Pan

If the streusel clings to the pan, it’s likely because the butter melted too much during baking. Next time, press the streusel firmly onto the cake (don’t just sprinkle it). For easier release, line the pan with parchment paper and grease it lightly with butter.

If it happens anyway, run a hot knife around the edges before inverting the cake onto a plate. A quick brush with melted butter after baking also helps loosen any stubborn bits. 🧈
