Add the large egg and vanilla extract to the butter-sugar mixture and beat until fully combined. Mix in red gel food coloring until the dough is evenly tinted vibrant red.

Reduce mixer speed to low and gradually add the flour mixture to the wet ingredients, mixing until just combined to avoid overworking the dough.
05 -
Cover the dough bowl and refrigerate for 20 minutes to firm up for easier handling and better shaping.

Preheat oven to 350°F (175°C). Line two baking sheets with parchment paper to prevent sticking and promote even baking.

Scoop tablespoon-sized portions of chilled dough and roll each into a ball. Roll each ball thoroughly in granulated sugar and place on baking sheets, spacing them 2 inches apart.

Press the center of each dough ball gently with your thumb to create a thumbprint well. Refrigerate the shaped cookies for another 20 minutes to maintain shape during baking.
09 -
Bake the cookies for 12 to 14 minutes, rotating baking sheets halfway through, until the bottoms are lightly golden and cookies are set but still tender.

Allow the cookies to cool on baking sheets for 5 minutes before transferring to wire racks to cool completely.

Beat softened cream cheese with powdered sugar on medium speed until smooth and creamy.
