Place a heart shaped cookie cutter on a baking sheet lined with parchment paper. Gently press two tablespoon balls of dough into a cookie cutter. Remove the cookie cutter and repeat making hearts with all the dough. You can also hand form the cookies into a general heart shape. They don’t need to be perfect as we will be reshaping them when they get out of the oven.
You don’t have to worry how far apart they are as we are chilling the cookie dough, not baking it at this time. If desired add more sprinkles on top of the cookies, then cover with plastic wrap and place in the fridge for 1.5 to 2 hours, or up to 24 hours.
When ready to bake, preheat the oven to 350℉.
Place the cookie dough hearts on a baking sheet lined with parchment paper or a silicone baking mat, making sure they are 2-3 inches apart as they will spread. I recommend baking only 4-6 cookies as a time as you'll need to shape them when they come out of the oven, and if you bake too many they'll cool before you can shape them all.
Bake one sheet of cookies at a time for 8-10 minutes, or until the edges are golden.
Remove the cookies from the oven and immediately use a spatula or knife to push the cookies back into the shape of a heart. This must be done right from the oven when they are very hot, or they will not reshape.
Let cool on the baking sheet for 5-10 minutes, and then move to a wire rack to finish cooling. Repeat with the rest of the chilled dough.
