Ingredients You’ll Need
This recipe has two main components: the caramel apple topping and the buttery spiced cake. Preparing both separately makes assembly simple.
For the Caramel Apple Topping
- 3 tablespoons unsalted butter: Creates the rich buttery caramel base.
- 3/4 cup packed brown sugar: Provides sweetness and a deep caramel flavor. Light or dark brown sugar works.
- 1/4 teaspoon salt: Balances the sweetness.
- 2–3 medium apples (about 1 pound): Choose firm apples that hold their shape during baking.
- 1 tablespoon lemon juice: Helps prevent the sliced apples from browning.
Granny Smith, Honeycrisp, Fuji, and Gala are all good choices. A combination of tart and sweet apples creates a balanced flavor.
For the Spiced Cake Batter
- 1 1/2 cups (about 190g) all-purpose flour: Provides the cake’s structure.
- 1 1/2 teaspoons baking powder: Helps the cake rise.
- 1/2 teaspoon baking soda: Works with the buttermilk to create a tender crumb.
- 1/2 teaspoon salt: Enhances the other flavors.
- 1 teaspoon ground cinnamon: Adds classic warm spice.
- 1/4 teaspoon ground nutmeg: Provides a subtle aromatic flavor.
- 1/2 cup (113g) unsalted butter, softened: Adds richness and moisture.
- 3/4 cup (150g) granulated sugar: Sweetens the cake batter.
- 2 large eggs, at room temperature: Help bind the batter and provide structure.
- 1 teaspoon pure vanilla extract: Adds warmth and flavor.
- 1/2 cup (120ml) buttermilk: Helps create a soft, moist cake.
How to Make Caramel Apple Upside Down Cake
Step 1: Prepare the Pan and Oven
Preheat your oven to 350°F (175°C). Generously grease the bottom and sides of a 9-inch round metal cake pan.
Make sure the pan is oven-safe and not a springform pan, as the caramel mixture could leak from the bottom.
Step 2: Make the Caramel Base
Add the 3 tablespoons of butter, brown sugar, and salt to the prepared cake pan. Place the pan in the preheating oven for approximately 5 minutes, just until the butter melts.
Carefully remove the hot pan using oven mitts. Swirl gently to combine the melted butter and sugar into an even caramel layer.
Be careful not to touch the caramel because it will be extremely hot.
Step 3: Prepare the Apples
Peel the apples, remove their cores, and cut them into slices approximately 1/4 inch thick.
Place the slices in a bowl and toss them with the lemon juice. This helps prevent browning while you prepare the cake batter.
Step 4: Arrange the Apple Slices
Arrange the apple slices over the warm caramel in the cake pan. Start around the outside and work toward the center, slightly overlapping each slice.
Try to create an even layer so that the apples cover most of the caramel. They will soften and shrink slightly during baking.
Step 5: Mix the Dry Ingredients
In a medium bowl, whisk together the flour, baking powder, baking soda, salt, cinnamon, and nutmeg.
Set the mixture aside while preparing the wet ingredients.
Step 6: Cream the Butter and Sugar
In a large mixing bowl, beat the softened butter and granulated sugar together using an electric mixer on medium-high speed for approximately 2–3 minutes.
The mixture should become lighter in color and fluffy. This step helps create a tender cake texture.
Step 7: Add the Eggs and Vanilla
Add the eggs one at a time, beating after each addition until incorporated. Mix in the vanilla extract and scrape down the sides of the bowl as needed.
Make sure the mixture is smooth before moving to the next step.
Step 8: Combine the Wet and Dry Ingredients
With the mixer on low speed, add the dry ingredients in three portions, alternating with the buttermilk in two portions. Begin and finish with the dry ingredients.
Mix only until the flour disappears. Avoid overmixing because it can make the finished cake dense or tough.
Step 9: Assemble the Cake
Spoon the cake batter carefully over the arranged apples. Use a spatula to spread it evenly, making sure the batter reaches the edges of the pan.
Try not to disturb the apple arrangement while spreading the batter.
Step 10: Bake Until Golden
Place the cake pan on the middle oven rack and bake at 350°F (175°C) for approximately 40–50 minutes.
Check the center with a toothpick. It should come out clean or with a few moist crumbs, without wet batter.
If the cake needs additional baking time, continue checking in short intervals to avoid overbaking.
Step 11: Cool Briefly Before Flipping
Remove the cake from the oven and place it on a wire rack. Let it rest in the pan for approximately 10 minutes.
This short resting period allows the caramel to settle slightly while remaining warm enough to release from the pan.
Step 12: Flip and Reveal the Cake
Run a thin knife around the edges of the cake to loosen any parts sticking to the pan.
Place a large, heat-resistant serving plate upside down over the cake pan. Wearing oven mitts, hold the plate and pan firmly together and carefully invert them in one confident motion.
Slowly lift the pan away. If any apple slices remain stuck, gently remove them with a spatula and arrange them back on top of the cake.
Allow the cake to rest for another 15–20 minutes before slicing. Remember that the caramel topping will still be very hot.
Tips for the Best Caramel Apple Upside Down Cake
- Choose firm apples: Apples that hold their shape during baking produce a more attractive topping.
- Slice evenly: Uniform slices cook at approximately the same rate.
- Use room-temperature ingredients: Butter, eggs, and buttermilk combine more easily when they aren’t cold.
- Don’t overmix: Stop mixing as soon as the ingredients are incorporated.
- Check the center: Test the cake rather than relying only on the baking time.
- Follow the cooling window: Flipping too early can make the cake unstable, while waiting too long may allow the caramel to harden and stick.
- Use a suitable serving plate: Choose a plate larger than the cake pan with enough space to catch any caramel.
Common Mistakes and How to Fix Them
Why Did My Apples Stick to the Pan?
The caramel may have cooled and hardened before the cake was inverted, or the pan may not have been properly greased. Follow the recommended resting time and loosen the edges before flipping.
Why Is My Cake Dense?
Overmixing the batter or adding too much flour can make the cake heavy. Measure the flour accurately and mix only until the ingredients are combined.
Why Is the Center of My Cake Undercooked?
The cake may need more baking time, especially if your apples release extra moisture or your oven runs cool. Check the center with a toothpick and continue baking until it comes out without wet batter.
Why Is My Caramel Too Runny?
The topping may still be very hot when the cake is flipped. Allow the cake to rest for approximately 10 minutes before inverting it. The caramel will also thicken slightly as the cake cools.
Why Did My Cake Break When I Flipped It?
Flipping too early can cause the cake to fall apart before its structure has settled. Let it rest for about 10 minutes, loosen the edges, and use a large plate that securely covers the pan.
Easy Variations to Try
Caramel Apple Cinnamon Cake
Add an extra 1/2 teaspoon of cinnamon to the cake batter for a stronger warm-spice flavor.
Pecan Caramel Apple Cake
Scatter a small handful of chopped pecans over the caramel before arranging the apple slices. They add a pleasant crunch and nutty flavor.
Maple Caramel Apple Cake
Replace 1 tablespoon of the brown sugar in the caramel topping with pure maple syrup for a subtle maple flavor.
Apple Pear Upside Down Cake
Replace one apple with a firm pear for a delicious variation with a slightly different sweetness and texture.
How to Make Buttermilk at Home
If you don’t have buttermilk, you can make a simple substitute using regular milk and an acidic ingredient.
Add 1 1/2 teaspoons of white vinegar or lemon juice to a measuring cup. Pour in enough regular milk to reach the 1/2-cup mark. Stir gently and let the mixture stand for 5 minutes before using.
The homemade substitute works well in this cake and provides the acidity needed to react with the baking soda.
How to Store Caramel Apple Upside Down Cake
Because this cake contains fresh apples and a moist caramel topping, proper storage helps maintain its quality.
- Refrigerator: Cover leftover cake and refrigerate for up to 4 days.
- Room temperature: If serving, keep it out for no more than 2 hours before refrigerating leftovers.
- Freezing: Wrap individual slices tightly and freeze for up to 2 months for best quality.
- Reheating: Warm individual slices in the microwave for approximately 10–15 seconds, adjusting as needed.
Allow frozen slices to thaw overnight in the refrigerator before reheating.
Frequently Asked Questions
What are the best apples for caramel apple upside down cake?
Granny Smith, Honeycrisp, Fuji, and Gala are excellent choices. Granny Smith apples provide tartness and structure, while sweeter varieties add a naturally sweet flavor.
Can I make caramel apple upside down cake ahead of time?
Yes. You can bake the cake a day ahead and refrigerate it once completely cooled. Bring it closer to room temperature before serving or warm individual slices gently.
Should I peel the apples before baking?
Peeling is recommended for this recipe because it creates a softer, more uniform apple topping. The slices also arrange more neatly without their skins.
Can I use a different cake pan?
A 9-inch round metal cake pan is ideal for this recipe. If using another pan size, make sure it has enough capacity and adjust the baking time as needed. Avoid springform pans because the caramel can leak.
