Chocolate Chip Mint Biscuits

I wanted chocolate mint biscuits, so I researched for recipes. My cooking goddess, Nigella, had these on her website. I tried them once and changed her recipe, slightly. Let's just say these biscuits do not last more than 24 hours in the house!

Ingredients

200g soft butter
300g brown sugar
2 teaspoon vanilla extract
2 large eggs
300g plain flour
70g cocoa powder
1 teaspoon baking powder
250 grams dark chocolate chips

Mint Glaze
75g icing sugar
1 tablespoon cocoa powder
2 tablespoons boiling water
¼ teaspoon peppermint essence

Method

Preheat oven to 160°C.
Cream the butter and brown sugar, then beat in the vanilla extract and the egg.
Mix the flour, cocoa and baking powder in a bowl and gradually beat in to the creamed mixture. Finally, fold in the chocolate chips.
Using a rounded 15ml-tablespoon measure, spoon out scoops of cookie dough and place on a lined baking sheet, leaving a little space in between each one.
Bake in the oven for 12 minutes and then let them sit on the baking sheet for a couple of minutes before moving them to a cooling rack, with some newspaper on the surface underneath to catch any escaping glaze later.
Put the glaze ingredients into a saucepan and heat until combined.
Using a teaspoon, zig-zag the glaze over each cooling cookie.
