Ingredients for apple walnut upside down cake
Pantry staples, fresh apples, and a handful of nuts create this showstopping one-pan dessert.
| Ingredient | Amount | Notes |
|---|---|---|
| All-Purpose Flour 🌾 | 2 ½ cups | Sifted for light texture |
| Granulated Sugar 🍚 | 2 cups | White or light brown |
| Light Brown Sugar 🍚 | ½ cup | Packed firmly |
| Unsalted Butter 🧈 | 1 cup | Cold and cubed |
| Large Eggs 🥚 | 2 whole | Room temperature |
| Vanilla Extract 💧 | 1 tbsp | Pure extract preferred |
| Baking Powder 🧂 | 2 tsp | Aluminum-free |
| Salt 🧂 | ½ tsp | Fine sea salt |
| Walnuts 🥜 | 1 ½ cups | Chopped, toasted |
| Light Brown Sugar 🍚 | ½ cup | For streusel, packed |
| Apples 🍏 | 4 medium | Thinly sliced, peeled |
| Lemon Juice 🍋 | 1 tbsp | Freshly squeezed |
| Cinnamon 🌿 | 1 tsp | Ground, for topping |
The apples are everything here—Honeycrisp or Fuji stay firm when sliced thin, but Granny Smith works too if you prefer tartness. Costco or Trader Joe's usually have the best selection, and organic is worth it for that clean flavor. Slice them 1/4-inch thick—any thicker and they'll turn mushy. Toss with lemon juice right away to prevent browning. I always buy extra walnuts because they toast up so beautifully, and toasting them in a dry pan for 3-4 minutes before chopping makes all the difference.
No walnuts? Pecans or hazelnuts work in a pinch, but walnuts have that perfect crunch. Running short on brown sugar? White sugar plus 1 tsp molasses mimics the moisture. The baking powder is non-negotiable—aluminum-free is key for a tender crumb. And if you're baking in a high-altitude area, add 1/4 tsp more baking powder. For the streusel, I like to mix the brown sugar and nuts first, then cut in the cold butter—smaller butter pieces mean better texture. The apples can be prepped the night before, but don't toss them in lemon juice until you're ready to bake.
This cake tastes even better the next day, so bake it in the morning if you can. Store leftovers wrapped tightly at room temperature for 3 days, or freeze slices for up to 3 months. The walnuts keep best in the freezer, but if you're using them within a week, the pantry is fine. I always make a double batch—half goes to neighbors because it disappears fast. And if you're feeling fancy, dust the top with powdered sugar right after flipping—trust me on that final touch.

Step-by-step instructions for apple walnut upside down cake
This one-pan wonder delivers caramelized apples, toasted walnuts, and a fluffy cake—all baked together perfectly.
🍳 Step 1: Caramelize the Apples and Prepare the Filling
Preheat your oven to 350°F and grease a 9-inch round cake pan generously with butter. In a large bowl, toss the 4 medium apples (thinly sliced and peeled) with 1 tbsp lemon juice and 1 tsp cinnamon. Arrange the apple slices in a circular pattern on the bottom of the pan, slightly overlapping but not crowded.
In a small bowl, mix 1.5 cups walnuts with 0.5 cup light brown sugar (packed). Sprinkle this mixture evenly over the apples, pressing down gently so it sticks. This creates the signature upside-down texture while adding crunch and sweetness. Bake for 15 minutes—this pre-baking step caramelizes the apples and toasts the walnuts before the cake batter goes on top.
👨🍳 Step 2: Cream Butter and Sugars for Light Texture
While the apples caramelize, beat the 1 cup cold cubed butter with 2 cups granulated sugar and 0.5 cup light brown sugar (packed) in a stand mixer fitted with the paddle attachment. Mix on medium speed for 3-4 minutes until light and fluffy. You'll see the mixture nearly double in volume and turn pale—this aeration is key for a tender cake.
I like to scrape down the sides of the bowl every 30 seconds to ensure even creaming. If your butter isn't cold enough, it'll melt into the sugar instead of creating those air pockets we want. The result should be smooth with ribbons forming when you lift the paddle.
👨🍳 Step 3: Mix Wet Ingredients and Combine
Add the 2 whole large eggs (room temperature) one at a time, mixing on low speed for 30 seconds after each addition until fully incorporated. Then stir in the 1 tbsp vanilla extract. In a separate bowl, whisk together the 2.5 cups all-purpose flour (sifted), 2 tsp baking powder, and 0.5 tsp salt.
With the mixer on low speed, gradually add the dry ingredients to the wet mixture. Mix just until combined—you should still see some flour streaks. Overmixing develops gluten, which makes the cake tough. The batter will be thick and slightly sticky, which is perfect for this recipe. Pour the batter over the caramelized apple and walnut mixture in the pan, spreading it evenly with a spatula.
🔥 Step 4: Bake to Golden Perfection
Return the pan to the oven and bake for 40-45 minutes or until a toothpick inserted into the center comes out clean. The cake will rise beautifully over the apple filling, creating that classic upside-down effect. Watch for golden brown edges and a slightly domed top—this indicates it's done.
Here's the thing—don't overbake. The cake will continue cooking slightly as it cools. If you leave it in too long, the apples will turn mushy and the cake might dry out. When you see the edges pull away from the pan slightly and the top spring back when touched, it's ready. Let it cool in the pan for 10 minutes, then run a knife around the edges before flipping it onto a plate.
⏰ Step 5: Flip and Serve Warm
This is the moment you've been waiting for! Gently invert the cake onto a serving plate, letting the caramelized apples and walnuts spill out beautifully. Let it cool for another 10 minutes before slicing—this gives the cake time to set slightly and makes serving easier.
The first bite should deliver warm, tender cake with bursts of caramelized apple and crunchy walnuts. Each slice reveals that perfect balance of sweet and tart flavors, with the apples staying moist and the walnuts adding texture. Serve with a dollop of whipped cream or a scoop of vanilla ice cream for the ultimate dessert experience.
Pro Tips For Making Apple Walnut Upside Down Cake
- Preheat Pan First: The cake pan needs a head start—get that thing in the oven before you mix anything. I learned this the hard way when the butter-apple layer stuck like glue because the pan was cold. Five minutes at 350°F (175°C) is all it takes, and your cake will come out cleaner.
- Use Room-Temp Butter: Cold butter in the streusel topping means lumps that won’t melt smoothly. Take that butter out of the fridge at least 30 minutes early—or even overnight if you’re prepping ahead. Trust me, your streusel will be buttery perfection, not a dry, crumbly mess.
- Don’t Overmix the Batter: This isn’t pancake batter—stop mixing after the flour just disappears. Overworking it makes the cake dense, and you’ll end up with a brick instead of that tender, fluffy texture. Give it 20 strokes max with a spatula, then call it done.
- Toast the Walnuts: Skip the raw walnuts—they’ll turn to mush in the oven. Toast them in a dry pan over medium heat for 3–4 minutes until fragrant. They’ll add depth to the streusel and keep their shape. (Yes, even if you’re in a hurry—just set a timer.)
Wine and beer pairings for apple walnut upside down cake
Sweet Wine Pairings
This cake’s caramelized apples and toasted walnuts call for wines with similar sweetness and depth. A Moscato d'Asti from Italy is my go-to—its light effervescence and peach notes complement the cake’s buttery richness without overpowering the apples. Serve it slightly chilled (45-50°F) to enhance its floral aromas. 🍷
For a more robust pairing, try a Late Harvest Riesling from Germany or Washington State. Its honeyed sweetness and citrus undertones mirror the cake’s caramelized flavors while adding a refreshing acidity. Look for bottles with 10-15g residual sugar to match the dessert’s intensity.
Spiced Beer Options
If you prefer beer, a Belgian Dubbel like Westmalle Dubbel works beautifully. Its caramel and raisin notes harmonize with the walnuts and apples, while the malt sweetness balances the cake’s buttery texture. Serve at 50-55°F to preserve its complexity.
For a lighter option, a Honey Brown Ale (like New Belgium Honey Brown) adds a subtle sweetness and nutty undertones that enhance the walnuts. The low bitterness ensures the dessert’s flavors remain the star. 🍺
Coffee Pairing
Skip the alcohol and opt for a dark roast coffee with notes of caramel and chocolate. A Sumatra Mandheling or Costa Rican Tarrazú brewed strong and served warm will highlight the cake’s depth. The natural oils in the coffee beans create a satisfying contrast to the cake’s buttery texture.
For an espresso-based option, try a cortado (equal parts espresso and steamed milk) to cut through the richness without overwhelming the dessert’s delicate flavors. The creamy texture pairs perfectly with the cake’s moist crumb.

Frequently asked questions
Can I use frozen apples instead of fresh?
Fresh apples are ideal for this recipe because they caramelize beautifully and hold their texture. However, you can use frozen apples in a pinch—just thaw them first and pat them completely dry before slicing. The key is to slice them 1/4-inch thick and toss with lemon juice immediately to prevent browning. Frozen apples may release more moisture, so you might need to bake the prepped pan for 10-12 minutes before adding the batter to help absorb excess liquid.
Why did my cake stick to the pan?
This usually happens if the pan wasn't greased properly or if you skipped the 10-minute cooling step before flipping. Always use a 9-inch round cake pan and grease it generously with butter or use a nonstick spray. For extra insurance, line the bottom with parchment paper cut to fit. Also, make sure the cake is fully cooled in the pan—if it's too hot, the batter will stick when you try to flip it. A light dusting of flour on the parchment can also help prevent sticking.
Can I make this cake ahead of time?
This cake actually tastes even better the next day, so it's perfect for making ahead. After flipping and cooling, wrap it tightly in plastic wrap and store at room temperature for up to 3 days. For longer storage, slice the cake and freeze individual portions for up to 3 months. To serve, simply thaw at room temperature for 1-2 hours or warm in the oven at 300°F for 10 minutes to restore its fresh-baked appeal.
What's the best way to toast the walnuts?
Toasting walnuts enhances their flavor and crunch significantly. Heat a dry skillet over medium heat and add the walnuts in a single layer. Toast for 3-4 minutes, stirring frequently, until they turn a light golden brown and smell nutty. Watch closely—they can go from perfect to burnt in seconds! Let them cool completely before chopping. For extra flavor, you can also toast them in the oven at 350°F for 8-10 minutes, stirring halfway through.
Can I substitute walnuts with another nut?
Yes, but the texture and flavor will change slightly. Pecans work well and have a similar buttery flavor, while hazelnuts add a richer taste. For a different texture, try almonds or even candied pecans if you're feeling adventurous. Just remember that different nuts toast at different rates—almonds and hazelnuts may need slightly less time than walnuts. If substituting, use the same 1.5 cups measurement by volume, but adjust the toasting time based on the nut's size and density.
