Pre-heat oven to 350 f. Cover your rolling pin and working surface with a bit of flour; roll the dough to aprox 5 mm thickness and cut your cookies with a 2" round cookie cutter
Place cookies on a cookie sheet lined with parchment paper. Bake for 10-11 mins; remove from the oven and let cool for 3-4 minutes, then transfer over to a wire rack to cool completely
Pipe hearts into your cookies with royal icing or candy melts using a guide (paper, ruler, scraper) to stay in a straight line. Let them set and enjoy!
