Ingredients

Hazelnut Meringue:

  • 8 egg whites
  • 500 g granulated sugar
  • 250 g finely chopped hazelnuts

Nutella Buttercream:

  • 8 egg yolks
  • 240 g icing sugar
  • 1 tsp vanilla extract
  • 240 g unsalted butter, at room temperature
  • 2–4 tbsp Nutella (adjust to taste)
  • 3 bananas cut in slices

Instructions

Prepare the Meringue:

  1. Preheat oven to 200–225°F (90–110°C). Line a 16”x11” (40×28 cm) baking pan with parchment paper.
  2. In a stainless steel bowl, combine egg whites and granulated sugar. Whisk over a hot water bath until the mixture reaches 120°F (49°C).
  3. Transfer to a stand mixer and beat on high speed until stiff peaks form.
  4. Gently fold in the chopped hazelnuts.
  5. Spread the mixture evenly into the prepared pan.
  6. Bake for 1–2 hours, or until crisp but not browned. Baking time depends on how crunchy you prefer your meringue.
  7. Allow to cool completely. Then, carefully peel off the parchment and slice the meringue in half using a serrated knife.

Make the Buttercream:

  1. Combine egg yolks and icing sugar in a stainless steel bowl or double boiler. Whisk over hot water until the mixture warms to about 120°F (50°C).
  2. Remove from heat, add vanilla, and let it cool.
  3. Beat the mixture in a stand mixer with room temperature butter until light and fluffy.
  4. Add Nutella and mix until incorporated. Taste and add more Nutella if you want a stronger Nutella taste.

Assemble the Cake:

  1. Place one half of the meringue on a serving platter.
  2. Spread a thin layer of buttercream over the surface.
  3. Slice the bananas, add lemon juice, and layer them over the buttercream.
  4. Add more buttercream on top of the bananas, then place the second meringue layer over everything.
  5. Spread the remaining buttercream over the top of the cake.
  6. Drizzle with 2–3 tablespoons of Nutella (use a piping bag or spoon).
  7. Refrigerate for at least 1 hour to set.
  8. cut into 12 squares and garnish with a few banana slices.

Serving Suggestions

  • Serve chilled for a clean slice and refreshing contrast between the crunchy meringue and creamy filling.
  • Pairs beautifully with a cup of espresso or a glass of dessert wine.
  • Dust with cocoa powder or sprinkle extra chopped hazelnuts for a more decorative finish.

Storage Tips

  • Refrigerator: Store in an airtight container in the fridge for up to 3 days. The meringue may soften slightly over time, but the flavor remains rich and satisfying.
  • Freezer: Not recommended due to the banana filling, which doesn’t thaw well. If needed, freeze without the bananas and add them fresh before serving.

Variations & Substitutions

  • No bananas? Substitute with strawberries or raspberries for a fresh twist.
  • Nutella alternative: Try melted dark chocolate or a homemade hazelnut spread.
  • Hazelnuts: You can use finely chopped almonds or walnuts for a different nutty profile.
  • Dairy-free: Substitute butter with a vegan butter alternative and ensure your Nutella substitute is dairy-free.

Frequently Asked Questions

Can I make the meringue ahead of time?
 Yes! You can bake the meringue a day ahead and store it in an airtight container at room temperature.

What if I don’t have a thermometer?
 You can still proceed by gently warming the egg mixtures until they’re warm to the touch, but using a thermometer is recommended for best results.

Is the cake overly sweet?
 Despite the sugar in the meringue and buttercream, the lemon with the banana help balance the sweetness. If desired, reduce the sugar slightly in the buttercream.

Conclusion

This Crunchy Hazelnut Meringue Cake is a dreamy dessert that balances texture and flavour in every bite. The delicate meringue layers, velvety Nutella buttercream, and fresh banana slices create a dessert that’s rich, creamy, and memorable. Perfect for holidays, birthdays, or just treating yourself and your loved ones.
