Hazelnut Chocolate Cake (Paleo, GF, DF)

Why You’ll Love Hazelnut Chocolate Cake Recipe

This cake delivers intense chocolate flavor with the nutty richness of toasted hazelnuts in every bite. Because it is made without traditional flour, it has a dense, luxurious texture that feels almost like a cross between a cake and a torte. The ingredient list is simple, yet the final result looks and tastes impressive.

You will also love that it works well for different dietary preferences. It is naturally gluten-free and dairy-free, and the maple syrup adds sweetness without refined sugar. The water bath helps the cake bake gently and evenly, creating a moist crumb that stays delicious even after chilling. It is a great make-ahead dessert since the flavor becomes even better after some time in the fridge.

Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

For the cake:

• 2 1/2 cups (375g) hazelnuts, toasted and peeled
• 6 ounces (170g) 100% dark chocolate
• 1/3 cup (64g) coconut oil, solid
• 1/3 cup (75g) full fat coconut milk or heavy cream
• 1/2 cup plus 2 tablespoons (190g) maple syrup
• 1 tablespoon hazelnut extract or hazelnut liqueur
• 1 teaspoon vanilla powder
• 1/4 teaspoon fine Himalayan salt
• 4 eggs, room temperature

For the topping:

• 1/3 cup hazelnuts
• Chocolate fudge topping

These ingredients come together to create a cake with bold flavor and a silky, melt-in-your-mouth texture. Using toasted hazelnuts is especially important because they bring out the warm, nutty depth that makes this dessert stand out.

Directions

1. Preheat your oven to 350°F. Grease the bottom and sides of an 8-inch round or square cake pan with coconut oil, then line the bottom with parchment paper for easy removal.
2. In a large heatproof bowl set over simmering water, melt the dark chocolate and coconut oil together. Once smooth, stir in the coconut milk until fully combined. Remove the bowl from the heat and mix in the maple syrup, hazelnut extract, vanilla powder, and salt.
3. Place the toasted hazelnuts in a food processor and grind them until they form a fine meal. Add the ground hazelnuts to the chocolate mixture and stir well with a spatula.
4. In a separate bowl, beat the eggs with a handheld or stand mixer for a few minutes until fluffy and doubled in volume. Gently fold the eggs into the chocolate and hazelnut mixture until fully combined.
5. Pour the batter into the prepared pan. Wrap the outside of the pan with aluminum foil, then place it in a larger deep baking dish. Fill the larger dish halfway with hot water to create a water bath.
6. Bake for 30 to 35 minutes, or until a toothpick inserted in the center comes out clean. Be careful not to overbake.
7. Let the cake cool in the pan for a few minutes before transferring it to a serving plate. Top with chocolate fudge sauce and chopped hazelnuts before serving.

Servings and timing

This recipe makes 20 servings, making it ideal for gatherings, celebrations, or prepping dessert ahead for the week.

Timing:

• Prep time: about 20 minutes
• Bake time: 30 to 35 minutes
• Total time: about 55 minutes

Because the cake is rich, smaller slices work very well. That makes it a smart dessert for parties where you want something elegant and satisfying without needing large portions.

Variations

One easy variation is to use heavy cream instead of coconut milk if dairy-free is not a concern. This creates an even richer texture and a slightly more classic ganache-like flavor.

You can also change the topping to suit the occasion. A glossy chocolate ganache, a light dusting of cocoa powder, or even fresh berries can all work beautifully. For a deeper flavor, add a small pinch of espresso powder to the chocolate mixture. If you want extra texture, stir a handful of chopped hazelnuts into the batter before baking.

For a more dessert-like presentation, serve each slice with coconut whipped cream or a spoonful of dairy-free vanilla ice cream. The cake can also be made in a round pan for a more formal look or a square pan for easier slicing.

Storage/Reheating

Store the cake covered in the refrigerator for up to 2 weeks. Because of its dense and fudgy texture, it holds up very well when chilled and often tastes even better the next day.

For serving, you can enjoy it cold straight from the fridge for a truffle-like texture, or let it sit at room temperature for about 15 to 20 minutes to soften slightly. If you prefer it a little warmer, heat individual slices very gently in the microwave for a few seconds. Be careful not to overheat, or the texture may become too soft.

If freezing, wrap slices tightly and place them in an airtight container. Thaw overnight in the refrigerator before serving.

FAQs

Can I use a different nut instead of hazelnuts?

Yes, although the flavor will change. Almonds are the closest substitute in texture, but hazelnuts give this cake its signature rich and nutty taste.

Do I have to toast the hazelnuts first?

Toasting is highly recommended because it enhances the flavor and makes the nuts easier to peel. It adds much more depth to the finished cake.

What does 100% dark chocolate do in this recipe?

Using 100% dark chocolate creates a very intense chocolate base and allows the maple syrup to control the sweetness. It gives the cake a bold, sophisticated flavor.

Can I make this cake without a food processor?

A food processor is the easiest way to grind the hazelnuts finely. Without one, it may be difficult to achieve the same smooth and even texture.

Why are the eggs beaten separately?

Beating the eggs until fluffy helps add lightness to the batter. This is especially important in a cake without flour, since the eggs help create structure.

Is the water bath necessary?

Yes, it helps the cake bake gently and evenly. This method reduces the risk of cracking or drying out and helps keep the texture moist and tender.

Can I make this cake ahead of time?

Yes, this is an excellent make-ahead dessert. The flavor deepens as it chills, so making it a day in advance can actually improve the final result.

How do I know when the cake is done?

The cake is ready when a toothpick inserted into the center comes out clean or with just a few moist crumbs. Avoid overbaking so it stays rich and fudgy.

Can I use vanilla extract instead of vanilla powder?

Yes, vanilla extract can be used if needed. The flavor may be slightly different, but it will still complement the chocolate and hazelnut well.

Is this cake very sweet?

It is more rich and deeply flavored than overly sweet. The maple syrup adds balanced sweetness, but the overall taste is still quite dark and chocolate-forward.
