Ingredients for chocolate hazelnut cake

Eight simple ingredients transform into a Nutella-inspired cake with rich layers and crunchy topping.

The hazelnuts are non-negotiable for that signature Nutella flavor. Toast them in a dry pan for 5-7 minutes until fragrant, then rub them in a towel to remove skins—this step makes all the difference. I grab mine in bulk from Trader Joe's or the bulk section at Whole Foods for freshness. The dark chocolate? Ghirardelli or Lindt squares melt beautifully, but chop your own chips for a smoother texture. Room-temperature butter is key—microwave it for 40 seconds if needed, but don’t overheat. Flour gets packed down when measuring, so spoon it into the cup and level off.

No hazelnuts? Toasted pecans or walnuts work in a pinch, though the flavor won’t be identical. Swap dark chocolate for semi-sweet chips if that’s what you have, but know it’ll be slightly sweeter. Running low on powdered sugar for the topping? Crushed vanilla wafers add crunch and sweetness. The glaze can be made ahead—just keep it covered until serving. For extra richness, fold in 1 tbsp Nutella if you’ve got it, but it’s totally optional. The cake itself is forgiving, so don’t stress over minor substitutions.

This cake keeps beautifully—3 days at room temperature covered loosely, or 1 week refrigerated. The glaze sets as it cools, so assemble it just before serving. For make-ahead magic, bake the cake, wrap it tightly, and freeze for up to 2 months. Thaw at room temperature before adding the topping and glaze. The hazelnut topping stays crisp for 2 days if stored in an airtight container, so make it fresh if you can. Leftovers? Slice and reheat for 10 seconds to revive the texture.

Step-by-step instructions for chocolate hazelnut cake

Here's how to make a rich, moist cake with Nutella-like layers and a crunchy hazelnut topping.

Preheat your oven to 350°F. Spread the 1.5 cups hazelnuts on a baking sheet and toast for 8-10 minutes until fragrant and lightly golden. Let them cool slightly, then transfer to a clean kitchen towel and rub vigorously to remove the skins. This step ensures a smooth, nutty texture that won't be gritty.

Once cooled completely, pulse the hazelnuts in a food processor until they form a coarse crumble. Set aside—you'll use this later for both the cake layers and the crunchy topping. The texture should be like wet sand, not a fine powder. If you don't have a food processor, you can use a heavy-duty blender or even a rolling pin and ziplock bag for this step.

In a large mixing bowl, cream together the 1 cup unsalted butter and 2 cups granulated sugar on medium speed until light and fluffy, about 3-4 minutes. This step is crucial—you're incorporating air that will make your cake tender and give it that beautiful rise. Scrape down the sides of the bowl with a spatula to ensure even mixing.

Add the 2 whole large eggs, one at a time, mixing well after each addition. Then stir in the 1 tbsp vanilla extract and the 1.5 cups hazelnut crumble you prepared earlier. The batter will look thick and slightly streaky, but that's normal. In a separate bowl, whisk together the 1.5 cups all-purpose flour, 1 tsp baking powder, and 0.5 tsp salt. Gradually fold these dry ingredients into the wet mixture until just combined.

Divide the batter evenly between two 8-inch round cake pans that have been lightly greased and dusted with flour. Sprinkle half of the remaining hazelnut crumble over each layer—this will create that signature Nutella-like texture. Bake in the preheated oven for 25-30 minutes, or until a toothpick inserted into the center comes out clean. Rotate the pans halfway through baking for even browning.

Once baked, let the layers cool in the pans for 10 minutes before transferring to a wire rack to cool completely. This gradual cooling prevents the cakes from cracking. While they're cooling, prepare your glaze by mixing together the 0.5 cup powdered sugar, 2 tbsp honey, and 0.25 cup heavy cream until smooth. This glaze will add that signature shine and sweetness to your cake.

Place one cake layer on a serving plate and spread an even layer of the glaze over the top. You don't need to use all of it—just enough to create a thin, even coating. Dust the top with a light layer of the remaining hazelnut crumble, pressing gently so it sticks. Place the second cake layer on top and repeat the glaze and crumble process.

For the final touch, spread the remaining glaze over the entire cake and press the last of the hazelnut crumble onto the top. Let the cake sit at room temperature for at least 1 hour before slicing to allow the glaze to set properly. This waiting time ensures clean slices and prevents the crumble topping from falling off. Serve with a dollop of whipped cream or a scoop of vanilla ice cream for the perfect dessert experience.

Creative variations of this recipe

Italian Nutella Twist

Transform this cake into a true Italian-inspired dessert by swapping the honey glaze for a Nutella-based ganache. Melt ½ cup Nutella with ¼ cup heavy cream over a double boiler, then cool slightly before spreading between layers.

Top with a sprinkle of crushed pistachios for an authentic Italian café vibe. This variation is perfect for brunch or dessert menus—just be sure to use high-quality Nutella (I recommend the original Italian version from Ferrero for the best flavor). 🍫

Spiced Orange Glaze

Brighten up the cake with a zesty orange glaze by adding 1 tbsp fresh orange zest and 1 tbsp orange juice to the powdered sugar mixture. The citrus cuts through the richness of the chocolate and hazelnuts beautifully.

For extra warmth, add a pinch of cinnamon or cardamom—just ½ tsp is enough to enhance the flavor without overpowering. This variation works especially well with dark chocolate (70% cocoa) for a sophisticated touch. 🍊

Salted Caramel Layers

For a decadent twist, replace half of the hazelnut crumble with salted caramel bits. Melt ½ cup caramel sauce (I love Smucker’s or Trader Joe’s brands) and mix it with ½ cup chopped toasted hazelnuts.

Spread this mixture between the cake layers instead of the glaze, then top with the remaining hazelnut crumble. The salty-sweet contrast elevates the cake to restaurant-quality dessert status. 🍯

Espresso Infusion

Add a mocha-inspired depth by brewing 2 tbsp strong espresso and mixing it into the cake batter after adding the wet ingredients. The coffee enhances the chocolate flavor and pairs perfectly with the hazelnuts.

For an extra boost, add 1 tsp instant espresso powder directly to the dry ingredients. This variation is ideal for coffee lovers and pairs wonderfully with a cappuccino or latte. ☕

White Chocolate Swirl

Create a marbled effect by folding ½ cup melted white chocolate into the batter in swirls before baking. The contrast between the dark and white chocolate adds visual appeal and a delightful flavor twist.

Use high-quality white chocolate (like Ghirardelli) to avoid a grainy texture. This variation is especially festive for holidays or special occasions. 🎄

Almond Butter Alternative

For those with nut allergies or preferences, swap hazelnuts for almond butter. Replace the hazelnut crumble with 1.5 cups almond butter (I recommend Justin’s or Smucker’s) mixed with 1 tbsp honey to mimic the texture.

Toast 1.5 cups sliced almonds instead of hazelnuts for the crumble topping. The result is a rich, nutty cake with a different but equally delicious flavor profile. 🌰
