First, I mix the softened butter with sugar until creamy. Then, I add the egg and vanilla, blending until smooth. Dry ingredients go in last, forming a soft dough ready to chill.
I wrap the dough in plastic and chill it for at least an hour. This keeps the cookies from spreading too much in the oven. It also makes rolling easier.
I lightly flour my counter and roll the dough to about ¼ inch thick. Then, I press my heart-shaped cookie cutters and place the cookies on a parchment-lined sheet.
I preheat the oven to 350°F (175°C) and bake for 8–10 minutes. The edges should just start to turn golden. I let them cool on the sheet for a few minutes before transferring to a wire rack.
Once cooled, I like to get creative with icing, sprinkles, or even a dusting of powdered sugar. It’s fun to make each cookie unique!
