Savor heavenly, festive Orange Shortbread Cookie Sandwiches with buttery delights and luscious chocolate truffle filling in every bite.
Preheat the oven to 350°F (180°C) and line 2 baking sheets with parchment paper.
On a floured surface, roll out the dough to ⅛-inch (3mm) thickness and cut circles with a 2-inch (5 cm) cutter. Place 1-inch (2½ cm) apart on the prepared baking sheets.
Check the consistency of the ganache. It should be about the consistency of peanut butter – thick enough to hold its shape but not so firm that it can’t be piped. If it is too thick, warm it in the microwave for a few seconds at a time until it softens to the right consistency. If it is still too warm and runny, place it in the refrigerator and stir every 3 minutes until it firms up.
