Today's cake is a delicious vanilla and hazelnut cake. It's very sweet, but in a soft way, and its buttercream its made with pure hazelnut paste.
You can find the pure hazelnut paste in specialized shops, along with countless other flavours. So if you want to do this buttercream in any other flavour, you can do it!
This is a swiss meringue buttercream, which I love because of its smoothness and the fact that it doesn't need 400g of confectioners sugar to be made. This buttercream, but with milk chocolate, is the same that I used in the

Hazelnut Swiss Meringue Buttercream
to decorate a 20cm diameter cake
- 3 egg whites
- 150g sugar
- 180g butter (room temperature, cold)
- 1 tsp pure italian hazelnut paste
- Mix the egg whites with the sugar in a double boiler. Heat the mixture while stirring until the sugar has completely melted and it's opaque. To chech if the sugar has melted, rub some mixture between your fingers; if you do not feel any sugar in it, take the pot away from the heat.
- Whisk the mixture up at high speed until it's completely cold.
- Add the butter, cubed. Add only two or three cubes at a time, whipping up at every addition. Repeat until you have used all the butter. Whip until the buttercream looks smooth and light.
- Add the hazelnut paste until fully incorporated.
Attention: if the meringue was not completely cold after whipping it up, the butter will melt when you add it and the buttercream will be too liquid. If this happens, put the bowl in the fridge for half an hour until you have reached the desired consistency and whisk it up again.
This buttercream can be stored in the fridge for a week and in the freezer for six-eight weeks. To thaw it, put it on the fridge overnight. In both cases, whip it for 5 minutes before using it.
You may buy bottled egg whites in order to avoid having to throw away the yolks. In that case, these are the conversion in grams:
10 egg whites = 300gr
5 egg whites = 150gr
3 egg whites = 90gr
To make the cake:
- Divide the cake horizontally in three or two layers. Put a bit of buttercream between each layer.
- Cover the entire cake with a thin layer of buttercream, to catch the crumbs, and put the cake in the fridge for half an hour.
- Put a thicker layer of buttercream on the cake, covering all the sides, and smooth it with a spatula.
- Decorate the rest as you wish, with a pastry bag.
