Ingredients for apple sauce cake recipe uk
British baking essentials meet autumn flavors in this ultra-moist apple sauce cake.
| Ingredient | Amount | Notes |
|---|---|---|
| Unsweetened Apple Sauce 🍎 | 1 cup | Homemade or quality store-bought |
| Self-Raising Flour 🌾 | 3 cups | British standard for light texture |
| Caster Sugar 🍚 | 2 cups | Fine grain for even dissolving |
| Large Eggs 🥚 | 2 whole | Room temperature for best mixing |
| Unsalted Butter 🧈 | 1 cup | Softened, not melted |
| Vanilla Extract 🌿 | 1 tbsp | Pure vanilla for authentic flavor |
| Milk 🥛 | ½ cup | Whole milk for richness |
| Spiced Rum 🍹 | 2 tbsp | For streusel, use quality brand |
| Old-Fashioned Rolled Oats 🥣 | 1 cup | Not quick oats for texture |
| Light Brown Sugar 🍚 | ½ cup | Packed for streusel sweetness |
| Ground Cinnamon 🌶️ | 1 tbsp | Freshly ground preferred |
| Ground Ginger 🌿 | ½ tbsp | For warm spice depth |
| Salted Butter 🧈 | ½ cup | Cold cubes for streusel |
| Ground Nutmeg 🌶️ | ¼ tsp | Freshly grated for aroma |
| All-Purpose Flour 🌾 | ½ cup | For streusel binding |
Self-raising flour is non-negotiable here—British brands like Dr. Oetker or Doves Farm give that signature lift. The apple sauce should be smooth, not chunky—homemade from Bramley apples is ideal, but store-bought works too. Grab Bramleys from a UK supermarket if you're cooking in the UK, or any tart apple for the US. Caster sugar dissolves beautifully, but don't sub granulated—it won't give the same fine texture. The eggs need to be room temp, so take them out 20 minutes before mixing.
No spiced rum? Apple juice or orange juice adds moisture without the alcohol kick. For the streusel, quick oats won't work—rolled oats give that perfect crunch. Want more depth? Add a pinch of cardamom to the streusel. The butter for the streusel should be cold—cubed and straight from the fridge—so it creates those lovely flaky bits. If you're short on time, pre-shredded coconut can replace half the oats for extra texture.
This cake keeps beautifully—3 days wrapped at room temp or 5 days in the fridge. The streusel stays crispy if you store it in an airtight container. I always make a double batch—one for today, one for next week. The rum flavor actually improves with age, so it's perfect for making ahead. For serving, a dusting of icing sugar makes it look extra special without adding much sweetness.

Step-by-step instructions for spiced rum streusel apple sauce cake
Here's how to create a wonderfully moist cake with a boozy streusel crown that'll impress everyone.
Prepare the Cake Batter
Preheat your oven to 350°F (175°C) and grease a 9-inch round cake tin or line it with baking parchment. In a large mixing bowl, combine the 1 cup unsweetened apple sauce, 2 cups caster sugar, 1 cup softened unsalted butter, and 1 tbsp vanilla extract. Beat with an electric mixer on medium speed until the mixture is smooth and creamy.
Add the 2 whole large eggs, one at a time, beating well after each addition. Then stir in the 0.5 cup milk and 2 tbsp spiced rum. The rum adds a lovely depth of flavor and helps keep the cake moist. In a separate bowl, sift together the 3 cups self-raising flour and gently fold it into the wet ingredients using a spatula. Be careful not to overmix—the batter should be smooth but slightly lumpy.
Mix the Streusel Topping
In a medium bowl, combine the 1 cup old-fashioned rolled oats, 0.5 cup light brown sugar, 0.5 cup cold salted butter (cut into small cubes), 1 tbsp ground cinnamon, 0.5 tbsp ground ginger, 0.25 tsp ground nutmeg, and 0.5 cup all-purpose flour. Rub the mixture between your fingers until it resembles coarse crumbs with some larger oat pieces remaining. This texture is perfect for creating that crunchy crown.
For extra flavor, add the remaining 1 tbsp spiced rum to the streusel mixture and toss gently to coat the oats and spices. The rum will infuse into the streusel as it bakes, giving it a subtle boozy warmth that pairs beautifully with the apple sauce cake.
Assemble and Bake the Cake
Pour the cake batter into your prepared tin and spread it evenly. Sprinkle the streusel mixture evenly over the top, pressing down gently with your fingers to help it adhere. Place the cake in the preheated oven and bake for 40-45 minutes, or until a skewer inserted into the center comes out clean and the top is golden brown.
I like to check the cake at the 40-minute mark—sometimes ovens run hot, so it's good to be ready to remove it when it's just set. The streusel should be golden and slightly crispy, while the cake underneath should be moist and tender. Let the cake cool in the tin for 10 minutes before transferring it to a wire rack to cool completely.
Serve with Confidence
Once the cake has cooled completely, you'll notice the streusel crown has softened slightly but still maintains its crunchy texture. The cake itself should be wonderfully moist with a tender crumb, thanks to the apple sauce and self-raising flour. Serve slices at room temperature, and you'll be rewarded with a perfect balance of flavors—the sweetness of the apple sauce, the warmth of the spices, and the subtle boozy note from the rum.
This cake keeps well for up to 3 days in an airtight container, though I doubt it'll last that long! For the best experience, serve it with a dollop of whipped cream or a scoop of vanilla ice cream to complement the rich, spiced flavors.
Pro Tips For Making Apple Sauce Cake Recipe Uk
- Use Room-Temperature Eggs: I learned this the hard way—cold eggs from the fridge can make your batter too thick and lead to a dense cake. Let them sit in warm water for 5 minutes first, or just take them out of the fridge 10 minutes before mixing.
- Weigh Your Butter Properly: Unsalted butter is tricky—it’s easy to pack too much into the measuring cup, which throws off the moisture balance. Use a kitchen scale for precision (225g is about 1 cup), and don’t press it down. Spoon it in loosely for the right texture.
- Don’t Overmix the Batter: Self-raising flour is sensitive, and once you add the eggs, it’s easy to overwork it into a tough dough. Mix just until combined—lumps are fine, and stopping early keeps the cake tender. I used to beat it like a pancake mix, and the result was dry.
- Check for Doneness Early: Apple sauce cakes can look underdone when they’re actually ready. Insert a skewer at the centre—it should come out clean with maybe a few moist crumbs, not wet batter. If you wait for a fully dry skewer, you’ll end up with a dry cake. Trust your nose too: the scent of apples should be rich, not raw.
Make-ahead tips for this recipe
Prep Ahead Strategy
The cake batter and streusel topping can be prepared 24 hours in advance—this is a game-changer for busy bakers. Store both mixtures in separate airtight containers in the fridge. The batter will thicken slightly, so give it a quick stir and let it sit at room temperature for 10 minutes before baking. The streusel stays fresh and flavorful, ready to be sprinkled right before baking. 💡
Freezer-Friendly Layers
For maximum convenience, bake the cake layers without the streusel and freeze them. Wrap each cooled layer tightly in cling film, then place in a freezer bag for up to 3 months. When ready to serve, thaw overnight in the fridge, add fresh streusel, and bake for 15-20 minutes at 350°F (175°C) to crisp it up. This method preserves the cake's moisture perfectly.
Streusel Make-Ahead Tip
The streusel mixture can be prepped 3 days ahead and stored in an airtight container at room temperature. The spices will deepen in flavor, creating a more aromatic topping. If storing longer than 2 days, keep it refrigerated. Bring it to room temperature before using to ensure even distribution on the cake. The rum flavor actually improves with time, so this is a great way to infuse extra depth. 🍹
Baking Timeline
Plan your baking session like a pro: Prepare the batter and streusel the night before, then bake fresh in the morning. The cake will still be warm and aromatic when you serve it, even if you've been busy all day. For a last-minute dessert, bake the cake layers without streusel, cool completely, then assemble with fresh streusel and bake for 10 minutes to toast the topping. This works beautifully for unexpected guests!
Storage Secrets
Once fully cooled, wrap the entire cake in plastic wrap followed by a foil layer to lock in moisture. Store at room temperature for up to 3 days or refrigerate for 5 days. The streusel stays crispy if you keep the cake in an airtight container. For longer storage, freeze the fully assembled cake (with streusel) for up to 2 months. Thaw overnight in the fridge before serving for perfect texture.
Serving Prep
Set the table with whipped cream or vanilla ice cream ready to serve alongside the cake. Dust with icing sugar just before serving to add a professional finish. If you're making this for a gathering, slice the cake 1 hour before serving to let the flavors meld. The rum aroma becomes more pronounced as the cake sits, making it even more irresistible. 💛

Frequently asked questions
Can I substitute apple sauce for something else in this cake?
You can use unsweetened applesauce as a 1:1 replacement, but for best results, stick with it. If you're out, try mashed banana (add 1 tsp baking powder per cup) or yogurt. Avoid pumpkin puree—it changes the texture and flavor profile completely. The apple sauce keeps this cake ultra-moist without being dense.
Why does my cake turn out dry?
Overbaking is the most common culprit—remove the cake when a skewer comes out clean (40-45 minutes). Another reason is overmixing the batter, which develops gluten. For extra moisture, brush the cooled cake with simple syrup (equal parts sugar and water, heated until dissolved). The rum and apple sauce should keep it tender, but this extra step ensures perfect texture.
Can I make this cake without alcohol?
Replace the spiced rum with apple juice or orange juice (same amount). For deeper flavor, add 1 tsp vanilla extract or ½ tsp almond extract to the streusel. The rum adds warmth, but the spices (cinnamon, ginger, nutmeg) will still shine. The cake will be just as moist and delicious!
How do I make this cake gluten-free?
Swap the self-raising flour for a 1:1 gluten-free self-raising blend (like Doves Farm GF) and add 1 tsp xanthan gum to the batter. For the streusel, use a GF flour blend and ensure your oats are certified gluten-free. Note the texture may be slightly denser, but the apple sauce keeps it tender. Always test your GF flour blend first in small batches.
What's the best way to serve this cake?
Warm slices pair perfectly with whipped cream or vanilla ice cream. For a British touch, serve with clotted cream and fresh berries. At room temperature, it's ideal for afternoon tea. If you love crunch, add a sprinkle of toasted flaked almonds to the streusel before baking for extra texture contrast.
