Step 1: Preheat the Oven and Prepare Baking Sheets
Preheat your oven to 350°F (175°C). Line two baking sheets with parchment paper to prevent the cookies from sticking.
Step 2: Prepare the Cookie Dough
In a medium bowl, whisk together the flour, baking powder, and salt.
In a large bowl, cream together the softened butter and granulated sugar using an electric mixer or hand whisk until the mixture is light and fluffy.
Add the egg and vanilla extract and continue mixing until well combined.
Gradually add the dry ingredients to the wet ingredients, mixing until a soft dough forms. If the dough is too sticky, add a tablespoon of milk or more flour until you get a workable dough consistency.
Divide the dough into two portions. Wrap each portion in plastic wrap and chill in the refrigerator for 30 minutes.
Step 3: Roll Out the Dough
Lightly flour your work surface and rolling pin. Roll out one portion of the dough to about 1/8-inch thickness.
Use the heart-shaped cookie cutter to cut out large hearts. Place the cookies on the prepared baking sheets, spacing them about 1 inch apart.
Step 4: Cut Out the Small Red Hearts
Use a small heart-shaped cookie cutter or a knife to cut out small hearts in the center of each cookie.
Gently remove the small heart-shaped pieces from the middle of the cookies. You should now have a heart-shaped cookie with a small heart-shaped hole in the center.
Step 5: Add the Red Heart Filling
If you’re using red candy melts, melt them according to the package instructions. Once melted, carefully spoon a small amount of red candy melt into the center of each cookie where the small heart-shaped hole is.
If using red icing, pipe a small amount of red icing into the center of each cookie. Be sure not to overfill the center.
Step 6: Bake the Cookies
Bake the cookies in the preheated oven for 8-10 minutes, or until the edges are lightly golden.
Allow the cookies to cool on the baking sheets for a few minutes before transferring them to a wire rack to cool completely.
Step 7: Serve or Decorate
Once the cookies have cooled, they are ready to serve! If desired, you can decorate the cookies with additional icing or sprinkles for extra flair.
