Pre heat the oven to 180c deg have ready 2 large baking trays lined with parchment paper.
Melt the butter and plain chocolate over medium heat. Take off the heat and stir in the instant coffee and leave it to cool a little before pouring it into the bowl of an electric mixer.
115 g unsalted butter, 100 g plain or milk chocolate chips , 1 teaspoon instant coffee powder
Add the white and brown sugars, lightly beaten eggs and vanilla. Mix until well combined.
140 g caster sugar, 140 g soft light brown sugar, 2 eggs , 2 teaspoons vanilla extract
Sift together the flour, cocoa powder and baking powder before adding to the chocolate mixture. Mix until well combined, scrap down the sides of the bowl as you go along.

Using a tablespoon or small ice cream scoop, place rounds of cookie dough balls onto a parchment-lined baking sheet. Leaving plenty of space for the dough to spread a little. I managed to make 20 cookies. 10 on each baking sheet that I pre prepared.
Bake in the centre of the oven for 10 - 12 minutes or until baked. The cookies will still be soft in the centre and continue to cook with the residual heat. DO NOT overbake or they will go hard. Leave to cool a little before placing them on a wire rack or cooling rack to cool completely.
The baking time will vary depending on how large or small the cookie dough balls are. Larger sizes may need an extra minute or two to bake.
