Ingredients for apple walnut upside down cake

Just twelve ingredients transform into a showstopping dessert with caramelized apples and crisp walnut topping.

Ingredient Amount Notes
All-Purpose Flour 🌾 2 ½ cups Sifted for light texture
Granulated Sugar 🍚 1 ½ cups White or light brown
Packed Brown Sugar 🍚 ½ cup Light or dark variety
Unsalted Butter 🧈 1 cup Room temperature, cubed
Large Eggs 🥚 2 whole Room temperature preferred
Vanilla Extract 🌿 1 tbsp Pure extract, not imitation
Baking Powder 🍞 2 tsp Aluminum-free recommended
Salt 🧂 ½ tsp Fine sea salt preferred
Chopped Walnuts 🥜 1 ½ cups Toasted for enhanced flavor
Packed Brown Sugar 🍚 ½ cup For streusel topping
All-Purpose Flour 🌾 ½ cup For streusel topping
Cinnamon 🌶️ 1 tsp Ground, not cassia
Fresh Apples 🍎 4 medium Firm, sweet variety (e.g., Granny Smith)
Lemon Juice 🍋 1 tbsp Freshly squeezed

The apples are the heart of this cake, so choose them carefully. Granny Smith or Honeycrisp hold their shape best during baking, but any firm, sweet apple works. I always buy mine from Whole Foods or the local orchard in season—they're sweeter and more aromatic than grocery store apples. If you can't find fresh, frozen unsweetened apples work in a pinch, but thaw and pat them dry first. The walnuts should be raw and unblanched for maximum crunch. Costco sells them in bulk for a great price, and toasting them in a dry pan for 5 minutes enhances their flavor dramatically. For the butter, Plugrá or Land O'Lakes are reliable choices, but always use unsalted to control the seasoning.

No Granny Smith apples? Fuji or Gala will work—they're sweeter but slightly softer when baked. Running short on walnuts? Pecans or hazelnuts make excellent substitutes, though the texture will differ slightly. The baking powder is crucial for lift—Bob's Red Mill aluminum-free version is my go-to. For the streusel topping, if you're out of cinnamon, cardamom or allspice add a unique twist. The lemon juice prevents browning in the apples, so don't skip it—freshly squeezed makes all the difference. If you're concerned about the cake being too sweet, reduce the brown sugar by 2 tablespoons and add an extra tablespoon of vanilla for depth.

Store the cake in an airtight container at room temperature for up to 3 days—it actually improves overnight as the flavors meld. For longer storage, wrap tightly in plastic and refrigerate for up to 5 days. The walnut topping stays crisp for about 2 days before softening slightly, so serve it fresh if possible. To reheat, warm slices in the oven at 300°F for 5-10 minutes to restore the crunch. This cake freezes beautifully—wrap individual slices in plastic and freeze for up to 3 months. Thaw at room temperature before serving for the best texture.

Step-by-step instructions for apple walnut upside down cake

Here's the method for a perfectly caramelized fruit layer and crispy walnut topping every time.

1

Prepare the Apples and Butter Mixture

Peel, core, and slice the 4 medium fresh apples into ¼-inch thick slices. Toss them immediately with the 1 tablespoon lemon juice to prevent browning. Arrange the apple slices in a single layer on the bottom of a 9-inch round cake pan, slightly overlapping them to create an even base.

In a small saucepan, melt the 1 cup unsalted butter over low heat until completely liquid. Remove from heat and stir in ½ cup packed brown sugar until fully combined. Pour this butter mixture evenly over the apple slices in the pan. The apples will begin to soften and release juices—this is normal and essential for that signature caramelized flavor.

2

Make the Streusel Topping

In a medium bowl, combine the 1.5 cups chopped walnuts, ½ cup packed brown sugar, ½ cup all-purpose flour, 1 teaspoon cinnamon, and ½ teaspoon salt. Mix thoroughly with your fingers or a fork until the walnuts are evenly coated with the dry ingredients. This mixture will form the cake's signature crunchy topping.

Spread the streusel evenly over the butter-apple mixture in the pan, pressing down gently to ensure good contact. The streusel should cover all exposed surfaces, creating a continuous layer that will bake into a golden, crisp topping. Don't worry if it looks uneven—it will settle as it bakes.

3

Prepare the Cake Batter

In a large mixing bowl, whisk together the 2.5 cups all-purpose flour and 2 teaspoons baking powder. In a separate bowl, beat the 2 whole large eggs until frothy, then whisk in the 1.5 cups granulated sugar, 1 tablespoon vanilla extract, and remaining ½ teaspoon salt. Gradually pour the wet ingredients into the dry ingredients while mixing on low speed until just combined.

Add the 1 cup melted butter (from the apple mixture) to the batter and mix until smooth. The batter should be thick but pourable—if it's too stiff, add 1-2 tablespoons of milk to reach the proper consistency. Pour the batter over the streusel layer in the pan, spreading it evenly with a spatula.

4

Bake to Golden Perfection

Preheat your oven to 350°F and place the cake pan on the center rack. Bake for 50-55 minutes until the top is deep golden brown and a toothpick inserted into the center comes out clean. The cake should spring back slightly when pressed gently in the center.

During the last 10 minutes of baking, you'll notice the cake pull away from the edges of the pan and develop a beautiful caramelized crust. This is when the magic happens—resist the urge to open the oven early. When done, remove from the oven and let the cake cool in the pan for 10 minutes before carefully inverting it onto a serving plate.

5

Invert and Serve Warm

Run a thin knife around the edges of the cake to loosen it from the pan. Place a large serving plate over the pan and, with a quick motion, invert the cake onto the plate. The apples should now be on top, caramelized and glistening, with the crispy walnut topping underneath.

Let the cake cool for an additional 15 minutes before slicing to allow the filling to set slightly. Each slice should reveal tender cake surrounding the caramelized apple slices, topped with the crunchy walnut streusel. Serve warm for the best texture and flavor experience.

Pro Tips For Making Apple Walnut Upside Down Cake

  • Preheat Pan First: The cake pan gets hot fast—put it in the oven for 5 minutes before adding the butter-sugar-apple mix. I learned this the hard way when the butter melted unevenly and the apples stuck like glue. A hot pan = even caramelization, no scrambling later.
  • Cut Apples Small: Slice those apples into ¼-inch chunks, not thick wedges. Thick pieces stay undercooked while the top browns, and you end up with a cake that’s dry on top but raw in the middle. Small pieces caramelize faster and soak up the syrup better—trust the process.
  • Don’t Overmix Batter: Stir the flour mixture just until combined—lumps are fine. Overmixing develops gluten and makes the cake dense instead of tender. I used to beat it like I was punishing it, and the texture suffered. Fold gently, like you’re tucking in a baby.
  • Use Room-Temp Butter: Cold butter creates pockets of steam that can make the cake sink in the middle. Let that butter sit out for 30-60 minutes until it’s soft but not melted. Sounds weird, but it works—your cake will rise evenly and stay moist longer. (Yes, even if you’re impatient like me.)

Perfect pairings for apple walnut upside down cake

Creamy Vanilla Ice Cream

This classic pairing transforms your cake into a decadent dessert experience. Use a high-quality vanilla bean ice cream like Breyers Natural or Häagen-Dazs Vanilla Bean—the creamy texture contrasts beautifully with the cake's crunchy walnut topping.

Scoop a generous portion onto each slice and watch the caramelized apples melt slightly into the cold ice cream. For extra indulgence, drizzle with warm caramel sauce before serving. 🍦

Spiced Apple Cider

Warm spiced apple cider elevates the cake's apple flavors to new heights. Heat 2 cups apple cider with 1 cinnamon stick, 2 star anise pods, and 1 strip orange peel in a saucepan until steaming.

Strain and serve warm—it complements the cake's caramelized notes perfectly. For a boozy twist, add 1 oz bourbon per cup. Serve in small mugs for a cozy dessert experience. 🍎

Whipped Cream Variations

Lightly sweetened whipped cream is a must for topping slices. For a classic touch, use Cool Whip or homemade whipped cream sweetened with 1 tbsp powdered sugar. For a gourmet upgrade, try crème fraîche or mascarpone whipped cream—both add richness that pairs wonderfully with the cake's walnut crunch.

Garnish with a sprinkle of ground cinnamon for warmth. ✨

Coffee Liqueur Drizzle

Add a sophisticated touch by drizzling Kahlúa coffee liqueur over slices before serving. The deep, roasted notes of the coffee complement the cake's caramelized apples and nutty walnut topping.

For a lighter option, use Tia Maria—both liqueurs enhance the dessert's depth without overpowering it. Serve immediately for the best flavor impact. ☕

Fresh Berries

Bright, fresh berries like strawberries or raspberries add a vibrant contrast to the warm cake. Toss them in a light honey-sugar syrup (mix 2 tbsp honey with 1 tbsp water) and arrange on top of the cake.

The tartness cuts through the sweetness, balancing each bite. This pairing works especially well for summer gatherings. 🍓

Warm Caramel Sauce

Homemade salted caramel sauce takes this dessert to the next level. Heat 1 cup granulated sugar in a saucepan until melted, then add ½ cup heavy cream and 1 tsp sea salt.

Simmer until thickened, then drizzle over warm cake slices. The sauce enhances the caramelized apples while adding a luxurious finish. Store-bought Trader Joe's caramel sauce works in a pinch. 🍯

Frequently asked questions

1

Can I use canned apples instead of fresh?

Fresh apples are ideal for their texture and flavor, but you can use canned apples in a pinch. Drain and pat them completely dry, then arrange them in the pan. For best results, toss them with 1 tablespoon lemon juice and 1 teaspoon cinnamon to mimic the fresh apple's natural sweetness and prevent sogginess. The baking time may be slightly shorter since canned apples are pre-cooked.

2

How do I prevent the cake from sticking to the pan?

Grease your 9-inch round cake pan thoroughly with butter or baking spray, then dust with flour or use a silicone baking mat. For extra insurance, sprinkle a thin layer of flour over the butter mixture before adding the streusel. The key is to invert the cake carefully after baking—let it cool in the pan for 10 minutes first, then run a thin knife around the edges before flipping.

3

Can I make this cake in a different-sized pan?

Yes, but adjust the baking time and ingredient quantities. For an 8-inch pan, reduce baking time to 40-45 minutes and use 3 apples and 1 cup walnuts. For a 10-inch pan, increase baking time to 55-60 minutes and use 5 apples and 2 cups walnuts. Always check for doneness with a toothpick—it should come out clean when fully baked.

4

Why did my walnut topping turn out soggy?

Soggy topping usually means the cake wasn't baked long enough or the streusel wasn't pressed firmly enough. Ensure your oven is fully preheated to 350°F and bake until the top is deep golden brown. Press the streusel down gently before adding the batter—this helps it stay crisp. If it still turns out soft, try baking for 5-10 minutes longer or increase the oven temperature to 375°F for the last 10 minutes.

5

Can I make this cake ahead of time?

This cake actually tastes better the next day as the flavors meld. Store it in an airtight container at room temperature for up to 3 days. For longer storage, refrigerate for up to 5 days. To reheat, warm slices in the oven at 300°F for 5-10 minutes to restore the walnut topping's crunch. The cake freezes well too—wrap individual slices and freeze for up to 3 months.
