Mix the soft butter with the mascarpone and sugar until you get a fine and fluffy cream.
Add the egg and mix until smooth.
Gradually add the flour and, when the dough becomes too hard to work, transfer to a mixer.
Carefully incorporate all the flour and then the essences.
You should have a soft, slightly sticky dough, which you place in the refrigerator for an hour.
Take the dough out of the fridge and roll it out into a 0.3cm (0.12 inch) thin sheet.
Cut out circles with a cookie cutter and stamp each circle, if you have a cookie stamp, if not, they work without.
Preheat the oven to 180 degrees Celsius (356 Fahrenheit) and line a large baking tray with baking paper.
Place the cookies on the tray one at a time being careful not to ruin the shape.
Bake for 10-12 minutes until they become lightly browned. Remove and place on a cooling rack to cool.
When completely cold, fill them with the delicious chocolate cream and enjoy. They are more than great.
Enjoy!
