Ingredients for apple sauce cake recipe uk
Unsweetened apple sauce and spiced rum create the heart of this autumnal masterpiece.
| Ingredient | Amount | Notes |
|---|---|---|
| Unsweetened Apple Sauce 🍎 | 1 cup | Homemade or quality store-bought |
| Spiced Rum 🍹 | ½ cup | Dark rum for deeper flavor |
| All-Purpose Flour 🌾 | 2 ½ cups | Sifted for light texture |
| Granulated Sugar 🍚 | 1 ½ cups | White or light brown |
| Baking Powder 🧂 | 2 tsp | Diamond Crystal preferred |
| Ground Cinnamon 🌿 | 1 ½ tsp | Freshly ground for warmth |
| Ground Nutmeg 🌿 | ½ tsp | Freshly grated preferred |
| Salt 🧂 | ½ tsp | Fine sea salt |
| Large Eggs 🥚 | 2 whole | Room temperature |
| Unsalted Butter 🧈 | 1 cup | Cold, cubed for streusel |
| Light Brown Sugar 🍚 | ½ cup | Packed for streusel |
| Old-Fashioned Rolled Oats 🌾 | 1 cup | Blended into flour for streusel |
| Vanilla Extract 🌸 | 1 tsp | Pure vanilla preferred |
The apple sauce is the soul of this cake—homemade is ideal (just cook and blend peeled apples with a pinch of cinnamon), but store-bought works too as long as it's unsweetened. For the rum, Captain Morgan or Gosling's deliver that perfect balance of warmth without overpowering. The flour should be sifted for a light, airy texture—King Arthur or Doves Farm are my go-tos for reliability. If you're baking in a dry climate, consider adding an extra 1 tbsp of milk to the batter for extra moisture. The cinnamon and nutmeg? Freshly grind them if possible—Penzeys bulk spices are worth the splurge for this recipe.
No spiced rum? Apple cider or brandy works in a pinch (reduce by half to avoid overpowering). Short on apple sauce? Mashed banana or pumpkin puree can substitute, but the flavor will shift slightly. The streusel topping is where the magic happens—blend the oats into flour for a finer texture, or leave them whole for extra crunch. For a nutty twist, swap half the oats for chopped walnuts. If you're baking at high altitude, reduce the baking powder by 0.5 tsp to prevent a domed cake. The vanilla extract should be pure—Nielsen-Massey is my secret weapon for that authentic flavor.
This cake stays moist for 4-5 days when stored in an airtight container at room temperature, but freeze half the batch for up to 3 months—it reheats beautifully. For serving, a dusting of powdered sugar or a drizzle of warm caramel sauce takes it to the next level. The streusel topping is best eaten fresh, but if you must reheat, cover with foil to prevent over-browning. Portion into individual slices for perfect serving—this cake is always a crowd-pleaser at autumn gatherings.

Step-by-step instructions for spiced rum apple sauce cake
This cake delivers legendary moisture and a perfect balance of spiced rum warmth through every tender bite.
Prepare the Streusel Topping
In a medium bowl, combine the 1 cup unsalted butter and 0.5 cup light brown sugar using your fingers or a fork until crumbly. The butter should be cold but workable—if it's too hard, let it sit at room temperature for 5 minutes before mixing. Add the 1 cup old-fashioned rolled oats, 1.5 teaspoons ground cinnamon, 0.5 teaspoon ground nutmeg, and 0.5 teaspoon salt, mixing until everything is evenly coated in the buttery sugar.
This streusel is the secret to that irresistible crunchy top layer. Press the mixture between your fingers to create a coarse, sandy texture—this ensures the perfect balance of crunch and tenderness when baked. Set aside while you prepare the cake batter, as the streusel will keep well at room temperature.
Mix the Wet Ingredients
In a large mixing bowl, whisk together the 1 cup unsweetened apple sauce and 0.5 cup spiced rum until fully combined. The rum adds depth of flavor and helps create that signature moist texture. In a separate bowl, beat the 2 whole large eggs until light and frothy—this incorporates air that will help the cake rise beautifully. Add the eggs to the apple sauce mixture and whisk vigorously for 1 minute until well combined.
I always use room-temperature eggs for this recipe—they blend more smoothly and create a lighter batter. The apple sauce and rum mixture should be completely homogeneous at this stage, with no visible streaks of egg or liquid. This step ensures the cake will have that signature moist crumb without being dense.
Combine Dry Ingredients
In a separate bowl, sift together the 2.5 cups all-purpose flour, 1.5 cups granulated sugar, 2 teaspoons baking powder, remaining 1.5 teaspoons ground cinnamon, 0.5 teaspoon ground nutmeg, and 0.5 teaspoon salt. Sifting is crucial here—it aerates the dry ingredients and prevents lumps in the final batter. Make a well in the center of the dry ingredients and pour in the wet mixture all at once.
Using a spatula, gently fold the dry ingredients into the wet until just combined—you should still see some flour streaks. Overmixing develops gluten and can make the cake tough. Add the 1 teaspoon vanilla extract and mix just until incorporated. The batter will be thick but pourable, with a rich, spiced aroma that hints at the flavors to come.
Assemble and Bake
Preheat your oven to 350°F (175°C) 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 about half of the streusel mixture over the top, pressing down gently to create an even layer. Pour the remaining batter over the streusel and top with the rest of the mixture, pressing down lightly with the back of a spoon.
Bake for 45-50 minutes, or until a toothpick inserted into the center comes out clean. The cake should be golden brown on top with a slightly domed appearance. Here's the thing—don't open the oven door during the first 30 minutes of baking. The sudden temperature drop can cause the cake to sink in the middle. When you do check, you'll see the edges pulling away from the pan and the streusel turning a beautiful golden brown.
Cool and Serve
Remove the cake from the oven and let it cool in the pan for 10 minutes. Then transfer it to a wire rack to cool completely. This resting period is crucial—it allows the cake to set properly and prevents it from becoming gummy in the center. The streusel will firm up as it cools, creating that perfect contrast with the moist cake beneath.
Slice into 8 equal wedges and serve at room temperature. The cake should be tender with a moist crumb, and the streusel should provide a delightful crunch with every bite. The spiced rum flavor will be subtle but noticeable, enhancing the natural sweetness of the apple sauce and creating a cake that's truly special—perfect for afternoon tea or as a comforting dessert.
Pro Tips For Making Apple Sauce Cake Recipe Uk
- Mix Dry First: Combine flour, sugar, and baking powder before adding apple sauce—this keeps the batter from getting gluey. I used to toss the wet and dry together, and the cake turned out dense and heavy. A quick 30-second whisk with the dry stuff first makes all the difference.
- Warm the Apple Sauce: Heat the unsweetened apple sauce to room temperature before mixing—cold sauce makes the batter thick and uneven. Just pop it in the microwave for 20 seconds or warm it in a saucepan. Your cake will rise better and stay moist longer.
- Measure Rum Precisely: Use a proper 1-teaspoon measure for the spiced rum—eyeballing it leads to either a boozy cake or one that tastes like nothing. If you’re not a fan of alcohol, swap it for extra vanilla extract or warm apple juice, but stick to the same amount.
- Avoid Overmixing the Batter: Stir just until the dry ingredients disappear—overmixing develops gluten and turns your cake into a dense brick. Fold in the rum last, and stop as soon as it’s combined. The batter should look thick but not fight you.
Creative variations of these flavors
Autumnal Spice Twist
Swap the traditional cinnamon for a warm chai spice blend—mix 1 tsp cinnamon, ½ tsp cardamom, ¼ tsp cloves, and ¼ tsp ginger—for a sophisticated depth. The cardamom adds floral notes that complement the rum beautifully, while cloves bring a subtle warmth. For extra richness, replace ¼ cup of the flour with almond flour—it enhances the nutty undertones of the streusel. 🌿
Citrus Zest Brightness
Add 1 tbsp lemon zest to the wet ingredients for a refreshing contrast to the rum’s warmth. The citrus cuts through the richness while brightening the apple sauce’s natural sweetness. Pair this with a lemon glaze after baking: mix ½ cup powdered sugar with 2 tbsp lemon juice and drizzle over cooled slices. For a tropical twist, use orange zest instead—it pairs surprisingly well with the spiced rum. 🍋
Nutty Streusel Upgrade
Transform the streusel into a pecan-praline crunch by blending ½ cup chopped pecans with the oats and adding 2 tbsp brown sugar to the butter mixture. Toast the pecans in a dry pan for 3-4 minutes until fragrant before mixing. For a decadent touch, fold in 2 tbsp caramelized sugar (made by cooking 2 tbsp sugar in a dry pan until amber). This adds a buttery, toasted sweetness that elevates the cake’s texture. 🌰
Boozy Variations
Swap the spiced rum for apple brandy (like Calvados) for a more refined flavor—it’s lighter but still packs depth. For a non-alcoholic version, use apple cider reduced by half (simmer 1 cup cider until ½ cup remains) and add ½ tsp vanilla bean paste for complexity. If you love coffee, stir 1 tbsp instant espresso powder into the dry ingredients—it pairs surprisingly well with the rum’s warmth. 🍹
Seasonal Fruit Layers
Add thinly sliced apples (like Bramley or Granny Smith) between the cake layers for extra moisture and texture. Toss the slices in 1 tsp cinnamon and a pinch of sugar before layering. For a summer version, use peaches or plums—their juiciness keeps the cake ultra-moist. In winter, try dried cranberries mixed into the streusel for a tart contrast. 🍎
Gluten-Free Adaptation
Replace the all-purpose flour with a 1:1 gluten-free baking blend (like Bob’s Red Mill) and add ½ tsp xanthan gum to improve texture. For the streusel, use gluten-free oats and blend them finely for a smoother crumb. The apple sauce and rum still work wonders—just ensure your baking powder is gluten-free to avoid a dense result. This version holds up beautifully for 3-4 days** when stored properly. 🌾

Frequently asked questions
Can I substitute apple sauce with something else?
Yes! For a similar moist texture, use 1 cup mashed banana or 1 cup pumpkin puree. Both work well but will slightly alter the flavor profile—banana adds sweetness while pumpkin brings earthy notes. If you prefer fruit, 1 cup unsweetened applesauce is ideal, but peach puree or plum jam (reduced by half) can also work in a pinch.
Why does my cake turn out dense?
Overmixing the batter or using cold eggs can make your cake dense. Always mix dry ingredients into wet just until combined—stop when you still see flour streaks. Use room-temperature eggs and sift the flour for better aeration. If the cake still feels heavy, try adding 1 tbsp milk to the batter or reducing the flour by 2 tbsp for a lighter crumb.
How do I make this cake gluten-free?
Replace the all-purpose flour with a 1:1 gluten-free baking blend (like Bob’s Red Mill) and add ½ tsp xanthan gum to improve texture. For the streusel, use gluten-free oats and blend them finely. Ensure your baking powder is also gluten-free to prevent density. The apple sauce and rum remain key ingredients—just adjust the liquid slightly if needed for consistency.
Can I bake this cake in a different pan size?
Yes, but adjust the baking time. For a 9-inch round pan, reduce time by 5-7 minutes (bake for 40-43 minutes). For a loaf pan, bake at 350°F (175°C) for 50-55 minutes. Always check doneness with a toothpick—it should come out clean. If using a different shape, spread the batter evenly and press the streusel lightly to ensure even baking.
How long does this cake keep, and can I freeze it?
Store at room temperature in an airtight container for 4-5 days—it stays moist thanks to the apple sauce. For longer storage, freeze half the cake (wrapped tightly) for up to 3 months. Thaw overnight in the fridge and reheat slices in the oven at 300°F (150°C) for 10 minutes to restore freshness. The streusel stays crispy when reheated this way!
