I give you the spread first cause the cake takes like 10 minutes, and you need the spread right away when the cake comes out of the oven
2 cup roasted hazelnuts
1 cup icing sugar
1/2 cup cocoa powder
1/2 teaspoon vanilla extract
3 tablespoons vegetable oil
a little water
put hazelnuts on a pan at 350F for 15 minutes or until the skins crack
roll in a towel, get most the skins off
put the warm hazelnuts in the food processor, grinding them down as much as you can, add the oil, add everything else, and if it is too sticky, and not blending well add some water tablespoon at a time to make it smoother
can be stored in the fridge for around 3 weeks
for the cake :
3 large eggs separated
1/4 cup granulated sugar
1/2 cup powdered sugar
1/2 cup + 2 tablespoons all purpose flour
1/2 teaspoon baking powder
line a 15x10 jelly roll pan with parchment paper
preheat oven to 425F
put egg yolks and granulated sugar in a mixing bowl beat until creamy
beat egg whites until frothy, add icing sugar beat until stiff peaks form.
add flour and baking powder to egg yolk mix
fold in the egg whites
pour onto the parchment paper and spread out to an even layer.
bake for 8-10 minutes
as soon as the cake comes out of the oven, while still warm, spread the hazelnut spread onto the cake. roll up while still warm- roll it the 15 inch way so you have a long log.
cut off both ends and put aside.
spread the hazelnut spread on the outside of the cake, and to the two cut off ends, attach to cake with tooth picks using the hazelnut spread as a glue. onto the hazelnut spread with a knife or chopstick, make lines like the bark on a log.
put in the fridge until the hazelnut spread hardens.
take out the tooth picks and dust with a mix of cocoa and icing sugar
perfect!
