Ingredients

Here is everything you will need to build this showstopping chocolate hazelnut cake from scratch. I have broken the ingredients into three parts: the chocolate sponge, the white chocolate buttercream, and the decoration.

Chocolate Sponge Cake

350g unsalted butter, softened
350g caster sugar (superfine sugar works too)
350g eggs (about 6 to 7 large eggs, at room temperature)
250g self raising flour
100g cocoa powder (unsweetened)
1.25 tsp baking powder
2 to 3 tbsp milk (whole milk preferred)

White Chocolate Buttercream

Butter (unsalted, softened)
Icing sugar (powdered sugar)
Melted white chocolate (cooled slightly)
Double cream (heavy cream)

Decoration and Filling

2 to 3 packs of Kinder Bueno (mix of milk and white chocolate varieties)
Cocoa powder, for dusting

You will also need two 7 inch baking tins, parchment paper, a handheld whisk or stand mixer, a weighing scale, a cake smoother, and a piping bag with your favorite nozzle.

Tips and Substitutions

Over the years I have baked this cake many times, and a few simple tricks make all the difference. Follow these tips and your chocolate sponge will turn out light, tender, and perfectly level.

Use a Weighing Scale

Baking by weight is far more accurate than using cups. A digital scale ensures your butter, sugar, and flour are exactly right. This is the single best step you can take for consistent results.

Bring Ingredients to Room Temperature

Cold butter, eggs, and milk do not cream together properly. Let everything sit on the counter for about 30 minutes before you start. Room temperature ingredients create a smooth emulsion and a lighter cake crumb.

Sift Your Dry Ingredients

Always sift the self raising flour, cocoa powder, and baking powder together. Sifting removes lumps and incorporates air, which gives your sponge a softer, more even texture. A quick sift takes seconds but makes a noticeable difference.

Ingredient Substitutions

If you do not have self raising flour, you can substitute it with all purpose flour plus 1.5 tsp of baking powder per 250g. For the buttercream, feel free to swap the double cream for whole milk in a pinch, though the texture will be slightly less rich.

Recipe Variation

This cake is wonderfully flexible, and you can adapt it to suit your taste without losing its charm. Here are a few of my favorite variations.

Swap the Buttercream

Instead of white chocolate buttercream, try a whipped milk chocolate ganache or a white chocolate ganache for a denser, glossier finish. Both options pair beautifully with the crunchy Kinder Bueno pieces.

Use a Vanilla Sponge

If you prefer a lighter, non chocolate base, swap the cocoa powder for an equal weight of all purpose flour and add 1 tsp of vanilla extract. The vanilla sponge lets the hazelnut wafer filling really shine.

Try a Different Filling

Crushed Kinder Bueno is my go to, but you can also fold in chopped roasted hazelnuts or a drizzle of Nutella between the layers for extra hazelnut flavor.

How to Decorate Chocolate Kinder Bueno Cake

This is where the magic happens. The decoration turns a simple layer cake into a stunning dessert that looks bakery made. Follow these steps and you will have a gorgeous cake every time.

Start with the base: Spread a tablespoon of white chocolate buttercream on a cake board to anchor the first cake layer. Place one chocolate sponge layer on top.
Add the filling: Spread a generous layer of buttercream over the first cake layer and smooth it out. Sprinkle crushed Kinder Bueno pieces evenly over the buttercream, then place the second cake layer on top.
Frost the entire cake: Cover the top and sides with the remaining white chocolate buttercream. Use a cake smoother to create clean edges and a flat top. Don’t worry if it is not perfect, the decoration will cover it.
Arrange the Bueno pieces: Press whole or halved milk and white chocolate Kinder Bueno bars around the base of the cake. Dust the top lightly with cocoa powder using a fine sieve.
Finish with piping: Fill a piping bag with leftover buttercream and pipe rosettes or swirls on top. Garnish each swirl with a small chunk of Kinder Bueno. Serve and enjoy!

Recipe FAQs

How do I make Chocolate Kinder Bueno Cake from scratch?

Start with a moist chocolate sponge cake made from cocoa powder, flour, sugar, eggs, and butter. Once cooled, layer with white chocolate buttercream and crushed Kinder Bueno pieces. Frost the outside with more buttercream and garnish with whole or halved Kinder Bueno bars.

What ingredients are needed for a Kinder Bueno Cake?

The cake requires all purpose flour, unsweetened cocoa powder, sugar, eggs, butter, milk, baking powder, and vanilla extract. For the frosting, use white chocolate, butter, powdered sugar, and heavy cream. Garnish with Kinder Bueno bars and optional chopped hazelnuts.

How should I store leftover Kinder Bueno Cake?

Store the cake in an airtight container in the refrigerator for up to 5 days. Let it sit at room temperature for 10 15 minutes before serving to soften the buttercream. Do not freeze the fully decorated cake as the white chocolate buttercream may separate.

Can I substitute the white chocolate frosting with milk chocolate?

Yes, you can use milk chocolate instead of white chocolate for a sweeter, richer frosting. Simply melt the milk chocolate and mix it into the buttercream base. The texture will be similar, but the flavor will be less sweet and more chocolate forward.

How many calories are in a slice of Kinder Bueno Cake?

Calories vary by recipe but a typical slice (about 150g) contains around 450 550 calories, including the sponge, buttercream, and Kinder Bueno pieces. For a lighter version, you can reduce the sugar or use a lower calorie frosting alternative.

Is this cake suitable for children?

Yes, Kinder Bueno Cake is generally safe for children, but be mindful of the sugar content and potential allergens like dairy, gluten, and hazelnuts. For younger children, consider using a nut free chocolate wafer alternative and a dairy free buttercream.
