Sugar-Free Chocolate Hazelnut Snack Cake with Frosting

Introduction

Sugar-free chocolate hazelnut snack cake is a rich, nutty, and satisfying dessert made with almond flour, cocoa powder, chopped hazelnuts, eggs, melted butter, monk fruit sweetener, and a creamy chocolate frosting. It has a soft chocolate cake base, a smooth cocoa frosting, and a crunchy hazelnut topping that makes every bite feel indulgent.

This recipe is perfect when you want a homemade chocolate treat without regular sugar. Instead of all-purpose flour and white sugar, this cake uses almond flour and monk fruit sweetener. As a result, it is naturally lower in net carbs than a traditional chocolate snack cake while still feeling rich and dessert-like.

Moreover, hazelnuts make this cake special. Their toasted, nutty flavor pairs beautifully with cocoa and vanilla, creating a taste that feels warm, deep, and slightly elegant. The chopped hazelnuts inside the cake add texture, while the hazelnuts on top bring a pleasant crunch.

Another great thing about this sugar-free chocolate hazelnut cake is that it works well for many occasions. You can serve it as an afternoon snack, a low carb dessert, a coffee-time treat, or a simple cake for guests. Since it is baked in an 8×8-inch pan, it is easy to slice into neat portions and store for later.

History and Information About Chocolate Hazelnut Cake

Chocolate and hazelnut have been a classic pairing for a long time. Hazelnuts have a naturally rich, slightly sweet flavor that blends beautifully with cocoa. When the two are combined, the result is deep, nutty, and comforting. This is why chocolate hazelnut desserts are popular in cakes, spreads, cookies, pastries, and frozen treats.

Snack cakes are also loved because they are simple and practical. Unlike tall layer cakes, snack cakes are usually baked in a square or rectangular pan and served in smaller pieces. They are easy to prepare, easy to frost, and easy to share. Therefore, they are perfect for home baking.

This version takes the idea of a classic chocolate snack cake and adapts it into a sugar-free, low carb-style dessert. Almond flour replaces traditional wheat flour, helping create a moist and tender crumb. Monk fruit sweetener replaces regular sugar, while eggs provide structure and lift.

The frosting is made with softened cream cheese, Greek yogurt, cocoa powder, monk fruit sweetener, and vanilla extract. This creates a creamy topping that is lighter than a traditional buttercream but still rich enough to feel like a real frosting. The Greek yogurt adds a slight tang, while the cream cheese gives smoothness and body.

Because the cake is finished with chopped hazelnuts and dark chocolate chips, it has contrast in both flavor and texture. The cake is soft, the frosting is creamy, and the topping is crunchy and chocolatey.

Ingredients

For about 12 servings, you will need:

Chocolate Hazelnut Cake

1 1/2 cups almond flour
1/2 cup hazelnuts, roughly chopped
3 tablespoons unsweetened cocoa powder
4 large eggs
4 tablespoons monk fruit sweetener
3 tablespoons Kerrygold butter, melted
1 teaspoon pure vanilla extract
1 teaspoon baking powder

Chocolate Frosting

4 oz Philadelphia cream cheese, softened
4 oz Fage Greek yogurt 0%
3 tablespoons unsweetened cocoa powder
3 tablespoons monk fruit sweetener
1 teaspoon pure vanilla extract

Topping

1/4 cup hazelnuts, roughly chopped
1 tablespoon Lily’s dark chocolate chips

Preparation Step by Step

Step 1: Preheat the Oven and Prepare the Pan

First, preheat your oven to 350°F.

Line an 8×8-inch baking pan with parchment paper. Leave a little parchment hanging over the sides so you can lift the cake out easily after baking. This makes slicing cleaner and helps prevent the cake from sticking.

Because almond flour cakes can be more delicate than traditional flour cakes, parchment paper is very helpful. It supports the cake and makes serving much easier.

Step 2: Whisk the Eggs

Crack the eggs into a large mixing bowl.

Whisk them on high speed for about 3 minutes, or until they become pale and slightly airy. This step helps give the cake a lighter texture because the eggs add structure and lift.

Since this cake does not use wheat flour, the eggs play an important role. They help hold the almond flour together and create a soft, cake-like crumb. Therefore, do not skip the whisking step.

Step 3: Add Butter, Sweetener, and Vanilla

Add the melted butter, monk fruit sweetener, and vanilla extract to the whisked eggs.

Whisk until everything is combined. The melted butter adds richness and moisture, while monk fruit sweetener provides sweetness without regular sugar. Vanilla extract rounds out the chocolate and hazelnut flavors and makes the cake taste warmer.

Make sure the melted butter is not too hot before adding it to the eggs. If it is too warm, it may affect the texture of the mixture. Let it cool slightly after melting for the best result.

Step 4: Fold in the Dry Ingredients

Add the almond flour, chopped hazelnuts, cocoa powder, and baking powder to the bowl.

Fold everything together gently until the batter becomes smooth and evenly mixed. Almond flour can clump slightly, so make sure there are no dry pockets left in the batter.

The cocoa powder gives the cake its chocolate flavor, while the chopped hazelnuts add crunch and nuttiness. Baking powder helps the cake rise slightly and keeps it from becoming too dense.

Do not overmix the batter. Stir only until everything is combined. This helps keep the final cake soft and tender.

Step 5: Spread the Batter Into the Pan

Pour the chocolate hazelnut batter into the prepared 8×8-inch pan.

Use a spatula to spread it evenly into the corners and smooth the top. An even layer helps the cake bake at the same rate throughout.

The batter will be thicker than a traditional cake batter because almond flour absorbs moisture differently. This is normal. Simply spread it gently with a spatula until the surface looks level.

Step 6: Bake the Cake

Bake the cake for about 24 minutes, or until the center is just set.

The cake should look firm on top, but it should not be overbaked. Almond flour cakes can dry out if baked too long, so start checking near the end of the baking time.

A toothpick inserted into the center should come out mostly clean, with a few moist crumbs. If it comes out with wet batter, bake for a few more minutes and check again.

Once baked, remove the pan from the oven and let the cake cool completely before frosting.

Step 7: Cool the Cake Completely

Allow the cake to cool fully in the pan.

This step is very important because warm cake will melt the frosting. If the frosting is added too early, it can become runny and lose its creamy texture.

Cooling also helps the cake set properly. Since this cake is made with almond flour, it becomes easier to slice once it has cooled.

For faster cooling, you can place the pan on a wire rack. However, avoid placing a hot cake directly in the refrigerator because sudden temperature changes can affect the texture.

Step 8: Make the Chocolate Frosting

In a mixing bowl, add the softened cream cheese and Greek yogurt.

Beat with a hand mixer until smooth. Then, add the cocoa powder, monk fruit sweetener, and vanilla extract. Beat for about 2 minutes, or until the frosting becomes fluffy and evenly combined.

The cream cheese gives the frosting structure and richness. Greek yogurt makes it lighter and adds a gentle tang. Cocoa powder brings deep chocolate flavor, while vanilla balances everything.

Make sure the cream cheese is softened before mixing. If it is too cold, the frosting may become lumpy.

Step 9: Frost the Cake

Once the cake is completely cool, spread the chocolate frosting evenly over the top.

Use a spatula to smooth the frosting into an even layer. You can make the top perfectly smooth or create soft swirls for a more homemade look.

Because the frosting is creamy and rich, you do not need a very thick layer. A balanced layer is enough to add flavor without overpowering the hazelnut cake.

Step 10: Add the Topping

Sprinkle the chopped hazelnuts over the frosting.

Then, add the dark chocolate chips on top. This gives the cake a beautiful finish and adds texture to every slice.

For deeper flavor, toast the hazelnuts in a dry skillet for about 3 minutes before using them. Toasting brings out their natural oils and makes the nutty flavor stronger. Let them cool before adding them to the frosting.

Step 11: Slice and Serve

Slice the cake into about 12 servings.

Use a sharp knife for clean squares. For the neatest slices, wipe the knife between cuts. The cake can be served immediately after frosting, but it also tastes delicious after chilling because the frosting firms up slightly.

Serve it with coffee, tea, or a glass of cold milk. It also works well as a small dessert after dinner or as a rich snack during the day.

FAQ

Can I Make This Cake Without Hazelnuts?

Yes, you can make this cake without hazelnuts. However, the flavor and texture will change. You can replace them with chopped almonds, walnuts, pecans, or simply leave them out for a smoother chocolate cake.

Can I Use Almond Flour Instead of Regular Flour?

This recipe is already designed with almond flour. Almond flour gives the cake a moist texture and helps keep it lower in carbs. It should not be replaced with coconut flour in the same amount because coconut flour absorbs much more liquid.

Can I Use Another Sweetener Instead of Monk Fruit?

Yes, you can use another granulated sugar-free sweetener, but sweetness levels may vary. Choose a sweetener that measures similarly to sugar or monk fruit for the easiest substitution. Taste the frosting before spreading and adjust if needed.

Why Does the Cake Need to Cool Before Frosting?

The cake needs to cool completely because warm cake will melt the cream cheese frosting. Cooling also helps the almond flour cake firm up, which makes it easier to frost and slice cleanly.

Can I Make This Chocolate Hazelnut Cake Ahead of Time?

Yes, this cake is a good make-ahead dessert. You can bake the cake, cool it, frost it, and store it in the refrigerator until ready to serve. The flavor often becomes even better after chilling for a few hours.

How Should I Store This Cake?

Store the cake in an airtight container in the refrigerator for up to 4 days. Because the frosting contains cream cheese and Greek yogurt, it should be kept chilled. Let it sit at room temperature for a few minutes before serving if you prefer a softer texture.

Can I Freeze This Cake?

Yes, you can freeze the unfrosted cake. Wrap it tightly and freeze for up to 1 month. Thaw it in the refrigerator, then add the frosting and topping before serving. Freezing with the frosting is possible, but the texture may change slightly after thawing.

How Can I Make the Hazelnut Flavor Stronger?

To make the hazelnut flavor stronger, toast the hazelnuts before adding them to the cake and topping. You can also add a small amount of hazelnut extract if desired. However, use it carefully because extracts can be strong.
