Ingredients for apple sauce cake recipe uk

Traditional British baking starts with these simple, comforting ingredients for a cake that feels like home.

The apples are the heart of this cake, so Granny Smiths are ideal—they hold their shape and add tartness that balances the sweetness. Tesco or Waitrose usually carry them year-round, but local markets have fresher stock in season. If you can't find them, Braeburn or Cox's Orange Pippin work too. For the streusel, old-fashioned oats (not quick oats) give the best texture—Quaker or McCormick brands are reliable. The cinnamon and nutmeg should be freshly ground if possible, as pre-ground spices lose their punch quickly. Penzeys or the spice aisle at M&S are great for quality options.

No Granny Smiths? Fuji or Gala apples work in a pinch, but they’ll get mushy faster. Running low on walnuts? Pecans or hazelnuts toasted with the same cinnamon-nutmeg mix bring different flavors. The vanilla extract can be imitation, but Madagascar Bourbon or Tahitian vanilla from Waitrose or John West elevates the cake. For the streusel, if you’re out of olive oil, melted butter works just as well. The baking powder is crucial—Diamond Crystal (not aluminum-free) gives the right lift. And if you’re short on time, pre-diced apples from the salad bar save chopping, though fresh is always better.

This cake keeps beautifully for 3 days in an airtight container at room temperature, but it’s best enjoyed fresh. The streusel topping stays crisp for about 2 days if stored properly—wrap tightly with parchment between layers. For longer storage, slice and freeze individual portions with parchment between them for up to 3 months. Reheat slices in a 180°C oven for 5-10 minutes to restore the streusel’s crunch. The cake also freezes well before baking—just thaw overnight in the fridge before popping into the oven.

Step-by-step instructions for apple sauce cake with caramelized apple streusel

Here's how to create a perfectly moist apple sauce cake with a crunchy streusel topping that stays tender for days.

In a medium bowl, combine the 0.5 cup light brown sugar, 0.5 cup old-fashioned rolled oats, 0.5 cup chopped walnuts, 2 tsp ground cinnamon, and 0.5 tsp ground nutmeg. Drizzle in the 0.25 cup extra-virgin olive oil and mix with your fingers until the mixture resembles coarse crumbs with some oil still visible.

This texture is crucial—it should hold together when pressed but still have some crunch. If it feels too dry, add a teaspoon of cold water. Set aside while you prepare the cake batter, as the streusel needs to be cold when added to prevent over-browning.

Preheat your oven to 350°F (175°C) and grease two 8-inch round cake pans, lining the bottoms with parchment paper. In a large mixing bowl, whisk together the 2.5 cups all-purpose flour, 2 tsp baking powder, 0.5 tsp salt, and 0.5 tsp ground nutmeg. Set aside.

In a separate bowl, beat the 0.75 cup softened unsalted butter and 1.5 cups granulated sugar together until light and fluffy—about 3-4 minutes—until the mixture is pale and doubled in volume. This step incorporates air, which helps create that signature tender crumb. Add the 2 whole large eggs, one at a time, mixing well after each addition, then stir in the 1 tsp vanilla extract. Finally, gently fold in the 1 cup unsweetened apple sauce until just combined.

Gradually add the dry ingredients to the wet mixture, alternating with 1/3 of the flour mixture first, then the remaining 2/3, mixing just until combined. Be careful not to overmix—stop as soon as the flour disappears. The batter should be thick but pourable.

Divide the batter evenly between the prepared cake pans, spreading it out to create even layers. Sprinkle half of the streusel mixture evenly over each cake layer, then gently press it down with your fingers to ensure good contact. This ensures the streusel bakes evenly and creates that perfect caramelized top.

Bake the cakes for 30-35 minutes, or until a toothpick inserted into the center comes out clean. The edges should be golden brown, and the tops should have a slightly crisp streusel layer. Rotate the pans halfway through baking for even cooking.

Here's the thing—don't overbake. The cakes will continue to set as they cool, and overbaking leads to dryness. Once done, remove from the oven and let the cakes cool in the pans for 10 minutes, then transfer to a wire rack to cool completely. This gradual cooling prevents cracking and maintains moisture.

Once the cakes are completely cool, spread a thin layer of the remaining streusel mixture over the top of each cake. This final layer adds extra texture and flavor. Serve at room temperature for the best texture—this cake tastes even better the next day as the flavors meld together.

The result should be a perfectly moist cake with a tender crumb and a caramelized streusel topping that contrasts beautifully with the soft layers. Slice with a sharp knife for clean cuts, and enjoy with a cup of tea or coffee.

Storing and reheating this recipe

Room Temperature Storage

This cake stays fresh for up to 3 days at room temperature when stored in an airtight container—I use Tupperware with a tight-sealing lid. The streusel topping remains crisp for about 2 days, so store it wrapped in parchment paper between layers to prevent sogginess. Place the cake on a wire rack inside the container to avoid condensation buildup, which can make the base damp. 💛

Refrigerator Refresh

If you’ve left it out longer than 3 days, pop the cake in the fridge for up to 5 days. To revive the streusel’s crunch, warm slices in a 180°C oven for 5-10 minutes—just until the top is golden again. For extra moisture, brush the warm cake with a little apple juice or honey before serving. The fridge also works well for storing individual slices wrapped in cling film.

Freezing for Later

Freeze the whole cake (unbaked or baked) for up to 3 months—I wrap it tightly in aluminum foil followed by a zip-top freezer bag to lock in freshness. For baked cake, slice first and separate layers with parchment paper to prevent sticking. Thaw overnight in the fridge before reheating. If freezing unbaked, bake straight from frozen, adding 5-10 minutes to the cook time.

Reheating Secrets

Microwave reheating works in a pinch: place a slice on a plate, cover with a damp paper towel, and heat on 50% power for 20-30 seconds. For oven reheating, wrap the slice in foil and bake at 160°C for 8-10 minutes—this keeps the streusel crisp while warming the cake evenly. Avoid the toaster; it’ll dry out the cake faster than a desert sun. 🔥
