The British butter is non-negotiable here—it's what gives this cake its signature richness. M&S or Waitrose unsalted butter are my go-tos, but any good-quality European-style butter works. The golden syrup should be authentic, not the corn syrup substitutes you sometimes find. Look for Lyle's Golden Syrup in the baking aisle—it's worth seeking out. Granny Smith apples are ideal for their tartness, but Braeburn or Cox's Orange Pippin work beautifully too. Peel them carefully and slice evenly for consistent caramelization. The spiced rum adds depth, so Captain Morgan or Gosling's are excellent choices—just don't overdo it.
No golden syrup? A mix of molasses and corn syrup (1:1 ratio) gets you close, though it won't be identical. Short on oats? Crushed digestive biscuits make a great substitute for the streusel. The apples can be prepped ahead—just toss them with a sprinkle of cinnamon to prevent browning. For extra flavor, add a pinch of cardamom to the streusel. The baking powder is crucial—double-acting ensures proper rise, but if you only have single-acting, add an extra 1/4 tsp baking soda. The rum can be swapped for apple cider or orange juice if you prefer a non-alcoholic version, though the flavor will differ slightly.
This cake keeps beautifully for 3 days at room temperature, though it's best enjoyed fresh. For longer storage, wrap tightly in parchment paper and keep in an airtight container. The caramelized top freezes well for up to 3 months—just thaw at room temperature before serving. I always make a double batch. The leftovers reheated briefly in the oven make amazing French toast the next morning. For serving, a dusting of powdered sugar or a drizzle of extra golden syrup adds that bakery-fresh touch.

- Golden Syrup Magic: That sticky, caramelized syrup? It’s the star. The Granny Smiths stay tart while the syrup softens into a glossy, buttery blanket—like dessert got a British hug.

Step-by-step instructions for apple upside-down cake with caramelized top
Follow these precise techniques to achieve a perfect caramelized apple topping and moist spiced cake.
Prepare the Caramelized Apple Topping
Preheat your oven to 350°F. In a 9-inch ovenproof skillet, melt 1 cup unsalted butter over medium-low heat until fully liquid. Remove from heat and stir in 0.5 cup golden syrup and 0.5 cup brown sugar, whisking until completely combined. Arrange the 4 medium Granny Smith apples (peeled and sliced into ¼-inch pieces) in a single layer in the skillet, pressing them gently into the caramel mixture.
Return the skillet to the oven and bake for 15 minutes. This initial baking allows the apples to soften slightly and begin caramelizing. Remove from the oven and let cool for 5 minutes—this prevents the apples from slipping when you invert the cake later. The caramel should be thick and glossy with just a hint of golden color at the edges.
Make the Spiced Rum Streusel
In a medium bowl, combine 2.5 cups all-purpose flour, 1.5 cups granulated sugar, 2 tsp ground cinnamon, 0.5 tsp ground nutmeg, 0.5 tsp salt, and 0.5 cup old-fashioned rolled oats. Using your fingers, gently mix until the oats are evenly distributed throughout the dry ingredients. This creates a coarse, textured streusel that will add delightful crunch to the cake.
In a separate small bowl, whisk together 2 large eggs, 1 tsp vanilla extract, and 2 tbsp spiced rum. Gradually pour the wet ingredients into the dry mixture, stirring just until combined. The dough should hold together when pressed but not be overly wet. Avoid overmixing—this can develop gluten and make the cake dense.
Assemble and Bake the Cake
Carefully transfer the skillet with the caramelized apples to the center of a 9-inch round cake pan. Spoon the streusel mixture evenly over the apples, pressing down gently to ensure even coverage. The streusel should completely cover the apples and extend slightly up the sides of the pan.
Bake in the preheated oven for 35-40 minutes, or until a toothpick inserted into the center of the cake comes out clean. The cake should be golden brown with a slightly crisp streusel topping. If the edges brown too quickly, tent loosely with aluminum foil after 20 minutes to prevent overbrowning.
Invert and Serve
Remove the cake from the oven and let it cool in the pan for 10 minutes. Place a large serving plate over the pan and, using oven mitts, quickly invert the cake onto the plate. The caramelized apples should now form the top layer of your cake. Let the cake cool completely on the plate for at least 20 minutes before slicing—this ensures clean slices and prevents the caramel from running.
Serve warm with a dollop of whipped cream or a scoop of vanilla ice cream. The contrast between the warm, spiced cake and the cool topping creates an unforgettable dessert experience. Each slice should reveal perfectly caramelized apples with a moist, flavorful cake beneath.
Pro Tips For Making Apple Upside Down Cake Recipe Uk
- CHILL THE APPLE CORE: I learned this the hard way—slicing Granny Smiths straight from the fridge makes them turn mushy in the syrup. Cut them at room temperature, then pop the slices back in the fridge for 10 minutes before arranging. This keeps their shape while they caramelise properly.
- MELT SYRUP SLOWLY: Golden syrup burns faster than you’d think. Heat it gently in a small saucepan over medium-low heat, stirring constantly, until it’s just runny—about 3-4 minutes. If you rush it, you’ll end up with bitter bits instead of that glossy, sticky base.
- PRESS THE BUTTER HARD: Don’t just dot the butter in the pan—press it flat with a spoon or your fingers. This stops it from pooling in the centre while baking, ensuring even browning and a proper caramelised crust. Yes, it looks weird, but it works.
- TEST DONENESS WITH A SKEWER: The cake might look golden but still be raw inside. Insert a skewer into the centre—it should come out clean with a few moist crumbs. If it’s sticky, give it another 5-10 minutes. Overbaking dries out the cake; underbaking leaves it gummy.
Storing and reheating your leftovers
Room Temperature Storage
This cake stays fresh for up to 3 days at room temperature when stored properly. I wrap the entire cake tightly in parchment paper first, then place it in an airtight container to lock in moisture. The golden syrup and spiced rum help preserve freshness, but I always check for any signs of drying out before serving. The caramelized top remains intact if you avoid cutting through it too soon. 🧈
Refrigerator Refresh
For longer storage, refrigerate the cake for up to 5 days. The cold temperature actually enhances the flavors, making each slice taste even more aromatic. When ready to serve, I bring it to room temperature for 30 minutes before slicing—this prevents the caramel from becoming too stiff. A quick 10-second zap in the microwave (covered with a damp paper towel) revives any slightly cooled slices beautifully. 🍎
Freezing for Later
The caramelized top freezes exceptionally well for up to 3 months. Wrap the cake tightly in plastic wrap, then place it in a freezer bag with all air removed. When ready to enjoy, thaw overnight in the refrigerator. For a quick treat, I reheat individual slices in the oven at 300°F for 5-7 minutes—this restores the cake's warmth and makes the caramel glaze shine again. 🥶
Reheating Secrets
For the best texture, I recommend reheating slices in the oven. Place them on a baking sheet and warm at 325°F for 8-10 minutes until heated through. The oven method prevents the cake from becoming soggy while maintaining that perfect streusel crunch. If using the microwave, heat for 15-20 seconds on medium power, then let rest for 1 minute before serving. 🔥
Make-Ahead Magic
Prep the cake up to 24 hours ahead—this is perfect for holiday gatherings. Store the fully baked (but uninverted) cake in the fridge, then bake as directed when ready to serve. The apples will continue caramelizing slightly during the final bake, creating even deeper flavor. I often make a double batch and freeze half for future treats. The make-ahead approach saves time and ensures you're never baking under pressure. ⏰
Serving Warm Tips
Serve warm slices with a dollop of whipped cream or a scoop of vanilla ice cream for that bakery-style experience. For extra presentation, dust with powdered sugar or drizzle with extra golden syrup before serving. The contrast between warm cake and cool toppings makes every bite unforgettable. I always save a slice for later—it reheats beautifully for a cozy dessert any time of day. ✨

Frequently asked questions
Can I use any type of apple for this recipe?
Granny Smith apples work best due to their tartness, but Braeburn or Cox's Orange Pippin also create delicious results. Avoid overly soft varieties like McIntosh, as they won't hold up well during baking. The key is tartness—it balances the sweet caramel and streusel perfectly.
What's the best way to prevent the cake from sticking to the pan?
Grease your 9-inch cake pan thoroughly with butter, then dust with flour. For extra insurance, line the bottom with parchment paper cut to fit. The golden syrup base is sticky, so proper pan prep is crucial for clean removal. Always let the cake cool 10 minutes in the pan before inverting.
Can I make this cake without spiced rum?
Yes! Substitute with 2 tbsp apple cider or orange juice for a non-alcoholic version. The flavor will be slightly different but still delicious. For extra warmth, add ½ tsp mixed spice directly to the streusel mixture.
Why did my caramelized apples turn out too dark?
Overbrowning usually happens from baking too long at high heat. Start with 15 minutes at 350°F for the initial apple bake, then check frequently. If using a dark-colored skillet, tent with foil after 10 minutes to prevent excessive browning. The caramel should be golden, not black!
How do I make this cake gluten-free?
Replace the all-purpose flour with a 1:1 gluten-free baking flour blend (like Bob's Red Mill). Add ½ tsp xanthan gum to improve texture. For the streusel, use gluten-free oats and ensure your baking powder is certified gluten-free. The cake will be slightly denser but still delicious.
