This apple hazelnut cake recipe delivers moist layers of spiced apple and toasty hazelnut swirl in a single bowl—no fuss, no fussing. The secret lies in a simple yet strategic layering technique that keeps the cake tender while the nutty filling adds rich, buttery depth.
I perfected this version after years of baking, ensuring every slice balances sweet-tart apples with crunchy hazelnuts and a velvety crumb.
The recipe starts with a classic vanilla cake base, where finely diced apples release their juices during baking, keeping the texture moist without needing extra liquid.
A toasted hazelnut filling—made with just butter, sugar, and ground nuts—swirls through the batter, creating pockets of nutty goodness that contrast beautifully with the apple's natural acidity. The result? A cake that's perfect for fall gatherings, holiday desserts, or a cozy weekend treat.
Baking takes just 45 minutes at 350°F, with a simple one-bowl method that minimizes cleanup. The apples soften into a caramelized sweetness, while the hazelnuts add a toasty crunch that makes each bite satisfying.
Top with a dusting of powdered sugar or a drizzle of caramel for extra elegance, but the cake shines on its own.
For those with dietary preferences, substitutions are easy—swap butter for coconut oil or use almond flour for a nut-free version. The recipe scales perfectly for crowds, and leftovers stay fresh for days. Here's how to bake it to perfection.
Ingredients for apple hazelnut cake
Simple ingredients that transform into layers of apple-caramel and nutty richness.
| Ingredient | Amount | Notes |
|---|---|---|
| All-Purpose Flour 🌾 | 2 ½ cups | Sifted for light texture |
| Granulated Sugar 🍚 | 1 ¾ cups | White or light brown |
| Unsalted Butter 🧈 | 1 cup | Cold, cubed for creaming |
| Large Eggs 🥚 | 2 whole | Room temperature |
| Vanilla Extract 🌸 | 1 tbsp | Pure extract preferred |
| Baking Powder 🧂 | 2 tsp | Diamond Crystal preferred |
| Ground Cinnamon 🌿 | 1 tsp | Freshly ground preferred |
| Salt 🧂 | ½ tsp | Fine sea salt |
| Hazelnuts 🥜 | 1 ½ cups | Whole, toasted and ground |
| Light Brown Sugar 🍚 | ½ cup | Packed tightly |
| Apples 🍎 | 2 medium | Peeled, finely diced |
| Lemon Juice 🍋 | 1 tbsp | Freshly squeezed |
| Powdered Sugar 🍚 | ¼ cup | For dusting |
The apples are the heart of this cake—Granny Smith or Honeycrisp work best for that perfect tart-sweet balance. Grab them at Whole Foods or your local market in fall, but any crisp apple will do. Toasting the hazelnuts in a dry pan until golden deepens their flavor—Costco sells them pre-toasted if you're short on time. The butter needs to be cold for that tender crumb, so take it out of the fridge just before measuring. For the sugar, Domino brand is my go-to for reliability, but any granulated works.
No apples? Pear or peach works in a pinch, though the flavor shifts slightly. Running short on hazelnuts? Walnuts or pecans add a different but still delicious crunch. The vanilla extract can be swapped for 1 tsp vanilla bean paste if you're feeling fancy. For a nut-free version, replace the hazelnut filling with chopped dried apricots or raisins. The baking powder is non-negotiable—Diamond Crystal has slightly more lift than other brands, but any will do. If you're using pre-ground hazelnuts, toast them first for maximum flavor.
This cake keeps beautifully for 5 days wrapped in parchment, or 3 months frozen in individual slices. The apples soften overnight, so it actually tastes better the next day. For serving, dust with powdered sugar right before slicing—it melts into the warm cake. Leftovers? Store in an airtight container with a slice of bread to keep them fresh longer. The nutty filling solidifies slightly when chilled, so bring to room temperature before serving for the best texture.

Step-by-step instructions for apple hazelnut cake
This one-bowl method delivers a perfectly moist cake with rich hazelnut swirls and tender apple layers.
Prepare the Hazelnut Filling
Preheat your oven to 350°F. In a small bowl, combine the 1.5 cups hazelnuts with the 0.5 cup light brown sugar and 1 tbsp lemon juice. Spread this mixture evenly on a baking sheet and toast for 8-10 minutes until the hazelnuts turn golden brown and fragrant.
While still warm, transfer the toasted hazelnuts to a clean kitchen towel. Fold the towel over and gently rub the hazelnuts to remove their skins—this creates a smoother, creamier texture. Let them cool completely before grinding. Once cooled, pulse them in a food processor until you achieve a coarse, nutty paste with some small chunks remaining. Set this aside for the filling layer.
Cream Butter and Sugars for Light Texture
In a large mixing bowl, combine the 1 cup cold unsalted butter (cut into cubes) with the 1.75 cups granulated sugar. Using an electric mixer on medium speed, beat for 3-4 minutes until the mixture is light and fluffy with no graininess remaining. This creaming process incorporates air, which creates the cake's signature tender crumb.
Add the 2 whole large eggs one at a time, mixing well after each addition. Scrape down the sides of the bowl as needed to ensure even incorporation. Stir in the 1 tbsp vanilla extract and mix for another 30 seconds until fully combined. The batter should be thick and pale, with no streaks of egg white remaining.
Combine Dry Ingredients and Fold in Apples
In a separate bowl, whisk together the 2.5 cups all-purpose flour, 2 tsp baking powder, 1 tsp ground cinnamon, and 0.5 tsp salt. Sift the mixture directly into the butter-sugar mixture, then gently fold with a spatula until just combined—you should still see some flour streaks. Overmixing develops gluten and makes the cake dense.
Peel, core, and finely dice the 2 medium apples into small pieces (about ¼-inch cubes). Fold them into the batter along with half of the hazelnut paste you prepared earlier. The apples should be evenly distributed throughout the batter, adding natural moisture and subtle sweetness to each bite.
Create the Swirl and Bake to Golden Perfection
Pour the batter into a greased and floured 9-inch round cake pan. Using a rubber spatula, spread the remaining hazelnut paste evenly over the top of the batter, then gently swirl it into the center with the tip of the spatula. This creates beautiful marbled patterns throughout the cake.
Bake in the preheated oven for 45-50 minutes, or until a toothpick inserted into the center comes out clean. The edges should be golden brown, but the top may have a few cracks—this is normal. Let the cake cool in the pan for 10 minutes, then transfer to a wire rack to cool completely before dusting with the 0.25 cup powdered sugar.
Pro Tips For Making Apple Hazelnut Cake
- Cream Butter Properly: Beat the unsalted butter and sugar until it’s pale and fluffy—like a cloud, not a chunky paste. I used to skip this, and the cake turned out dense. Three minutes with a mixer (or five by hand) makes all the difference for that tender crumb.
- Toast Hazelnuts Low: Spread whole hazelnuts on a dry baking sheet and toast them at 325°F (not higher) until fragrant, about 10-12 minutes. Watch closely—they burn faster than you think, and bitter nuts ruin the whole dish. Cool them completely before chopping.
- Fold Apples Gently: Toss diced apples with lemon juice first, then fold them into the batter last—just before baking. Overmixing incorporates too much air, which can make the cake sink. Think "gently stir" not "beat like batter."
- Test Doneness Early: Stick a toothpick in the center at 30 minutes—if it comes out clean, pull it. Ovens run hot, and overbaking dries out the cake faster than you’d expect. A few minutes early lets the residual heat finish the job.
Serving suggestions for this apple hazelnut cake
Classic Powdered Sugar
For a timeless finish, dust the warm cake with ¼ cup powdered sugar using a fine-mesh sieve. This adds a delicate, snowy contrast to the golden-brown crust and enhances the nutty flavors. I like to do this right before serving so the sugar melts slightly into the cake's warmth. 💫
Caramel Drizzle
Elevate your presentation with a homemade caramel drizzle—simmer ½ cup granulated sugar with ¼ cup heavy cream until golden, then cool slightly. Drizzle over slices just before serving for a glossy, buttery touch that complements the apples. Store-bought caramel sauce (like Smucker's) works in a pinch.
Vanilla Ice Cream
Serve slices of this cake with a scoop of vanilla bean ice cream for a creamy, cool contrast. The ice cream's richness balances the cake's spiced apple and nutty notes. For extra indulgence, drizzle with warm maple syrup or hazelnut syrup before serving. 🍦
Whipped Cream Swirl
Top each slice with a dollop of lightly sweetened whipped cream and a sprinkle of toasted hazelnuts. The cream adds airiness, while the nuts reinforce the cake's signature flavor. For a festive touch, fold ½ tsp cinnamon into the whipped cream before serving.
Fresh Fruit Garnish
Brighten the plate with thin apple slices or pears arranged around the cake. The fresh fruit's crispness contrasts beautifully with the cake's tender crumb. A few mint leaves add a refreshing pop of color and a hint of brightness to cut through the richness. 🍏
Coffee Pairing
Serve the cake with a cup of espresso or dark roast coffee to enhance its nutty, caramelized flavors. The bitterness of the coffee balances the cake's sweetness, creating a perfect dessert-and-drink pairing. For a lighter option, try chai tea with a splash of milk.

Frequently asked questions
Can I use store-bought hazelnut spread instead of toasted hazelnuts?
Yes, but with adjustments! Replace the 1.5 cups toasted hazelnuts with 1 cup hazelnut spread (like Nutella) mixed with ½ cup brown sugar for the filling. The texture will be richer, but you'll lose some crunch. For a closer match, blend the spread with 2 tbsp ground hazelnuts to restore some nutty texture.
Why does my cake turn out dense instead of moist?
Overmixing the batter or skipping the creaming step (beating butter and sugar until fluffy) are the most common culprits. Ensure your butter is cold and beat it with sugar for 3-4 minutes until light. Also, don't overfill the pan—batter should reach only ⅔ full. If using apples with high moisture (like Fuji), pat them dry before dicing.
How do I make this cake nut-free?
Swap the hazelnut filling for ½ cup dried apricots or raisins (chopped) mixed with 2 tbsp lemon juice and ¼ cup brown sugar. For extra moisture, add 2 tbsp applesauce to the batter. The fruit will soften during baking, creating pockets of sweetness similar to the nutty swirl. Test with a small batch first to adjust sweetness.
Can I bake this cake in a different pan size?
Yes! For an 8-inch pan, reduce baking time to 35-40 minutes (batter should fill only ½ full). For a 10-inch pan, increase time to 50-55 minutes and add ½ cup extra batter**. Adjust oven rack position—if using a larger pan, place it on the middle rack to ensure even baking. Always check doneness with a toothpick.
What’s the best way to store leftovers?
Wrap cooled slices tightly in plastic wrap, then place in an airtight container with a slice of bread to absorb moisture. Store at room temperature for 3 days or refrigerate for 5 days. For longer storage, freeze slices individually for up to 3 months. Thaw overnight in the fridge—microwaving can make the cake gummy.
