Peanut butter.......a creamy, flavourful and rich treat. The addition of coconut flakes simply enhances the taste of these cookie squares.
- Preheat the oven to 190C/375F. Soften the butter at the room temperature. Beat in caster sugar and vanilla sugar until smooth. Add in egg yolk and whip on high speed until thick and smooth. Sift in flour, ground hazelnut and coconut shreds. Mix all the ingredients with your hand until a dough forms.
- Line a baking tray with parchment paper. Place on the cookie dough, top with the plastic film and roll it out to a 28x25 rectangle. Prick the entire surface with a fork and bake on the top shelf in the preheated oven for about 18 minutes.
- Mix together the peanut butter and egg whites until combined. Sift in the confectioners’ sugar until smooth. Once the bottom crust is done, remove from the oven and reduce the temperature to 160C/320F. Spread the peanut butter mixture on the top of the baked crust. Return it to the oven and bake for 25 minutes. Remove and cut into squares.
