To make a cookie coffee cup, you'll need the following ingredients: 6 1/3 tablespoons of softened butter, 1/3 cup of white sugar, 1/3 cup of raw cane sugar, 1/4 teaspoon of salt, 1/4 teaspoon of pure vanilla extract, 1/3 cup of all-purpose flour, 3 1/2oz of dark chocolate, 6 espressos, and 1 egg yolk.
Add the butter, sugars, vanilla, salt, and egg yolk to a bowl and mix well. Gradually add flour until you have a dough. Wrap and keep in the refrigerator to chill for an hour. Lightly flour a workspace and roll out dough to 4mm thick and cut strips of dough that are 6cm and 19cm wide.
Using metal rings, outlay the dough strips, overlapping to ensure they connect. Then cut out circles of the remaining dough for the bottom of your cups and connect them to the metal rings with the dough. Then place your cups onto a parchment paper-lined baking sheet and chill for around 30 minutes.
Preheat oven to 350F and then place your cups into the center of your preheated oven and bake for around 10 minutes on one side. Then turn and bake for a further 5 minutes. Remove from oven and leave to cool before detaching from the rings.
Melt half of the chocolate, then remove from heat and add the remaining chocolate; stirring as you go. Once cooled, glaze your cups with the melted chocolate and then leave them to harden in the refrigerator for around 20 minutes. Once cool, you can then fill it with coffee.
