Chocolate Peppermint Cookies - cooking recipe

Ingredients

1/2 cup butter, softened
1/2 cup granulated sugar
1 None large egg yolk
1 cup all-purpose flour, plus 2 tbsp
1/2 tbsp cocoa powder
1 1/2 cups powdered sugar, sifted
1/4 tsp peppermint extract
10.5 oz dark chocolate, chopped
1 tbsp vegetable oil

Preparation

Preheat oven to 350\u00b0F. Grease and line 3 baking trays with parchment paper.
Beat butter and sugar until smooth. Beat in egg yolk until combined. Sift flour and cocoa powder over top then fold in to form a soft dough. Shape into a disc, wrap in plastic wrap and chill for 30 mins.
Roll dough between 2 sheets of baking paper until 1/4 inch thick. Cut out cookies and place 1 inch apart on prepared trays. Bake for 12 mins, or until a cookie can be pushed gently without breaking. Let cool for 5 mins then transfer to a wire rack to cool.
Meanwhile, to make the peppermint icing, combine powdered sugar, peppermint extract and 2 tbsp water in a small bowl. Stir until smooth.
Spread 1 tsp peppermint icing evenly over top of each cookie. Place on a large wire rack set over a baking tray and set aside until icing is completely set.
Place chocolate in a small heatproof bowl over a small saucepan of simmering water (don't let water touch base of bowl). Stir until smooth. Remove bowl from heat and stir in oil. Transfer to a measuring cup. Pour a small amount of chocolate over cookies to cover. Let stand on a wire rack until set.
