Pre-heat the oven to 175°C and line a baking tray.

Melt the butter and leave to cool slightly. In a large bowl, beat the butter and sugar, then add the vanilla sugar, beaten egg and coffee and mix until well-combined.

Sift the flour with the baking soda and cinnamon and gently stir into the wet mixture until just combined, then add 40g of chocolate chips - the dough will be very sticky!

Spoon around one tablespoon of cookie batter onto the baking tray and top with a teaspoon of chocolate spread (you might need to give it a gentle burst in the microwave beforehand to make it a little more pliable - just don't melt it!). Top with another tablespoon of cookie batter, making sure the chocolate spread is completely covered. Repeat one at a time with the remaining batter, to make sure you have enough to make all of the covers!

Sprinkle the remaining chocolate chips over the tops and then bake for around 20 minutes until they are golden brown. Serve warm (perhaps with a little ice-cream?) or leave to cool! Enjoy!
