Banana, chocolate and hazelnut tray bake barsApril 15, 2016
Preheat the oven to 360F/180C.
Peel and mash the bananas in a large mixing bowl, add the butter and blend with an electric whisk.
Measure in the sugars and combine.
Weigh the flour, ground hazelnuts and cocoa together, and add the baking powder to the scale bowl. Mix the dry ingredients together before sifting half into the main mixing bowl.
Crack in a egg and mix everything together well, sift in the rest of the flour mix and crack in the remaining egg, combine.
Stir in the chopped hazelnuts.
Grease and flour the pan well so that the finished tray bake bars don't stick, pour in the batter and smooth out the top. Pop in the oven for 35-40 minutes, the cake will be done when the middle bounces back to the touch and a skewer inserted into the center comes out clean.
Leave to cool completely before sprinkling on the remaining hazelnuts and grated chocolate.
