Ingredients for apple walnut upside down cake
Just ten ingredients transform into a stunning upside-down cake with caramelized apples and nutty crunch.
| 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 🍯 | 1 cup | Dark brown preferred |
| Unsalted Butter 🧈 | 1 cup | Softened to room temp |
| Large Eggs 🥚 | 2 whole | Room temperature |
| Vanilla Extract 🌿 | 1 tbsp | Pure extract preferred |
| Baking Powder 🧂 | 2 tsp | Aluminum-free recommended |
| Salt 🧂 | ½ tsp | Fine sea salt |
| Walnuts 🥜 | 1 ½ cups | Chopped, toasted lightly |
| Red Delicious Apples 🍎 | 4 medium | Peeled, sliced 1/4-inch thick |
| Ground Cinnamon 🌿 | 1 tsp | Freshly ground preferred |
The apples are the star—Red Delicious or Honeycrisp hold up best during baking. Trader Joe's or local orchards often have the best selection, or grab organic at Whole Foods if you want to avoid pesticides. Slice them uniformly about 1/4-inch thick so they caramelize evenly. I always peel them first—it keeps the texture tender. For extra flavor, toss the slices with a pinch of cinnamon before arranging them in the pan. The walnuts should be raw and fresh—toasted in a dry pan for 3-4 minutes to bring out their aroma. No need to go fancy here, though—regular store-brand walnuts work perfectly.
No Red Delicious apples? Granny Smith or Fuji work just as well—they hold their shape better. The walnuts can be swapped for pecans or hazelnuts, though the flavor will shift slightly. Running short on vanilla? Almond extract at half the amount gives a similar depth. The butter must be softened to room temperature—microwave it for 40 seconds if it's straight from the fridge. For a richer cake, use European-style butter like Plugra. The cinnamon is non-negotiable, but if you're out, a pinch of nutmeg works in a pinch (literally). And yes, you can use pre-sliced apples from the store—just pat them dry first to prevent sogginess.
This cake keeps beautifully—3 days at room temperature covered loosely, or 1 week refrigerated in an airtight container. For longer storage, wrap tightly and freeze for up to 3 months. I like to slice it warm and serve with vanilla ice cream, but it's just as good cold. The caramelized apples get even more intense the next day, so leftovers are a bonus. Store the walnuts separately if you want to keep them extra crunchy, or sprinkle them fresh before serving for that restaurant-worthy finish.

Step-by-step instructions for apple walnut upside down cake
Here's how to create that perfect caramelized apple topping and tender crumb in one showstopping pan.
Prepare the Apples and Nut Topping
Preheat your oven to 350°F and lightly grease a 9-inch round cake pan with butter. Peel and slice the 4 medium Red Delicious Apples into ¼-inch thick slices. Arrange them in a circular pattern on the bottom of the pan, slightly overlapping but not crowded. This creates that gorgeous caramelized apple ring you see on top.
In a small bowl, toss the 1.5 cups Walnuts with 1 teaspoon Ground Cinnamon and spread them evenly over the apples. This forms the crunchy nut layer that will become the cake's signature topping when flipped. The cinnamon adds warmth that pairs perfectly with the apples.
Make the Cake Batter
In a large mixing bowl, cream together the 1 cup Unsalted Butter (softened), 1.5 cups Granulated Sugar, and 1 cup Packed Brown Sugar on medium speed until light and fluffy—about 3-4 minutes. You'll see the mixture nearly double in volume and become pale. This creaming process incorporates air, which gives your cake that tender, moist crumb.
Add the 2 whole Large Eggs, one at a time, mixing well after each addition. Then stir in the 1 tablespoon Vanilla Extract. In a separate bowl, whisk together the 2.5 cups All-Purpose Flour (sifted), 2 teaspoons Baking Powder, and ½ teaspoon Salt. Gradually fold the dry ingredients into the wet mixture until just combined—you should still see some flour streaks.
Bake Until Golden and Set
Pour the batter over the apple and nut mixture, spreading it evenly to the edges of the pan. Bake for 45-50 minutes or until a toothpick inserted into the center comes out clean and the top is golden brown. The cake is done when the edges pull away slightly from the pan and the top springs back when gently pressed.
Here's the magic moment: once it's fully baked, let the cake cool in the pan for 10 minutes. Then carefully invert it onto a serving plate. The caramelized apples and cinnamon walnuts will now be on top, creating that stunning presentation. Let it cool completely before slicing—this ensures clean, perfect layers.
Serve Warm with Vanilla Ice Cream
Slice the cake into 8 equal wedges (about 1-inch thick slices) and serve warm. The contrast of warm spiced cake with cool vanilla ice cream is unbeatable. The caramelized apples add natural sweetness that balances the rich cake batter, while the walnuts provide that satisfying crunch in every bite.
This cake keeps well at room temperature for 2 days or can be refrigerated for up to 4 days. For best texture, serve at room temperature or reheat briefly in the oven. The flavors only get better with time as the apples continue to caramelize slightly.
Pro Tips For Making Apple Walnut Upside Down Cake
- USE COLD BUTTER FOR BATTER: I learned this the hard way—adding softened butter to the dry ingredients makes the cake dense. Take the butter straight from the fridge, cut it into cubes, and mix it into the flour with a pastry cutter or your fingers until it’s pea-sized. The cold fat creates steam during baking, giving you that light, fluffy texture we all want.
- DON’T SKIP THE APPLE BUTTER LAYER: This isn’t the prettiest method, but it’s the tastiest. After arranging the apples and walnuts in the pan, spread a thin layer of apple butter (or a mix of diced apples and brown sugar) over the fruit before pouring the batter. It adds moisture and caramelizes beautifully during baking—trust me, your cake will thank you.
- BAKE UNTIL GOLDEN, NOT JUST SET: I was skeptical until I tried it: check for doneness at 325°F, but don’t pull it out when the edges look done. Wait until the top is deep golden brown, with a crack forming in the center. Overbaking is easy, but underbaking means a gummy middle—neither is ideal. A toothpick test works, but don’t rely on it alone.
- TOAST THE WALNUTS FIRST: Sounds weird, but it works: toast the walnuts in a dry pan over medium heat for 3-4 minutes until fragrant. This removes any bitterness and intensifies their flavor. Let them cool before arranging them in the pan—hot walnuts can melt the butter too fast and make the cake soggy. (Yes, even if you’re impatient like me.)
Make-ahead tips for this dish
Prep Ahead for Stress-Free Baking
The night before baking, slice and peel your 4 apples and toss them with 1 tsp lemon juice to prevent browning. Store them in an airtight container in the fridge—they’ll stay fresh until ready to arrange. I always do this because it saves 20 minutes of prep day-of. The walnuts can be toasted and chopped ahead too—just store them in a sealed bag at room temperature. 🍎
Batter Prep in Advance
Mix the cake batter up to 24 hours ahead and refrigerate it in an airtight container. The flavors meld beautifully overnight, and it’s one less thing to do on baking day. When ready to bake, let the batter sit at room temperature for 30 minutes before pouring over the apples. This ensures a smooth pour and even bake. I’ve made this cake with pre-mixed batter on Thanksgiving morning, and it turned out perfect.
Assemble the Cake Early
Arrange the apples and walnuts in the pan up to 8 hours before baking. Cover it loosely with plastic wrap and refrigerate. This gives the apples time to release juices and the nuts to settle, creating that perfect caramelized base. Just pop it in the oven when you’re ready—no last-minute scrambling. The cake will still bake beautifully, and the presentation will be flawless. 💫
Freezer-Friendly Assembly
For a true make-ahead masterpiece, assemble the entire cake (including batter) in the pan and refrigerate overnight. When you’re ready to bake, simply pop it in the oven straight from the fridge—no thawing required. The cold batter will take slightly longer to bake (55-60 minutes instead of 45), but the results are worth it. This is my go-to method for holiday baking when I want everything perfect without morning stress.
Storage Hacks for Leftovers
Slice the cooled cake and store it in an airtight container at room temperature for 3 days or refrigerate for 5-7 days. To reheat individual slices, wrap them in a damp paper towel and microwave for 10-15 seconds. For a restaurant-quality finish, sprinkle fresh walnuts on top before serving—this keeps them extra crunchy and adds that wow factor. 🥜
Gift-Worthy Packaging
Wrap individual slices in parchment paper and tie with twine for beautiful gifts. Store them in a gallon-sized freezer bag for up to 3 months. When ready to serve, thaw at room temperature for 1 hour or reheat in a 300°F oven for 10 minutes to restore that warm, gooey texture. This is perfect for holiday baking when you want to share the love without the last-minute rush.

Frequently asked questions
Why does my upside-down cake stick to the pan?
This happens when the pan isn't properly greased or the cake cools too long before inverting. Always use butter or nonstick spray on a 9-inch round pan, and let it cool for only 10 minutes before flipping. Run a knife around the edges first to loosen it gently. A light dusting of flour on the pan bottom can also help release the cake.
Can I use other fruits besides apples?
Try pears, pineapple, or berries for a fruity twist. Pears caramelize beautifully like apples, while pineapple adds a tropical sweetness. For berries, use a mix of strawberries and blueberries—just arrange them in a single layer since they're smaller. Adjust baking time if using softer fruits like pineapple.
How do I make the walnuts extra crunchy?
Toast the walnuts in a dry skillet over medium heat for 3-4 minutes until fragrant, then chop them coarsely. For maximum crunch, spread them on a baking sheet and bake at 300°F for 5 minutes before arranging on the apples. Store them in an airtight container until ready to use—this preserves their crunchiness.
What if my cake is too dense?
Overmixing the batter or using too much flour usually causes dense cake. Mix the dry ingredients into the wet just until combined—you should still see flour streaks. Also, make sure your butter is softened (not melted) and your eggs are at room temperature. For extra moisture, add 1 tbsp sour cream or yogurt to the batter.
