Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper.
In a medium bowl, whisk together the flour, baking soda, and baking powder. Set aside.
In a large bowl, cream the softened butter and sugar until light and fluffy.
Add the egg, vanilla extract, and milk to the butter mixture, mixing until fully combined.
Gradually add the dry ingredients to the wet ingredients, mixing until a dough forms.
Scoop tablespoon-sized portions of dough and roll them into balls.
Roll each dough ball in red sanding sugar until fully coated.
Place the dough balls on the prepared baking sheet, spacing them about 2 inches apart.
Bake for 8-10 minutes, or until the cookies are slightly puffed and set but not browned.
Remove the cookies from the oven and immediately press a Hershey’s Candy Cane Kiss into the center of each cookie.
Let the cookies cool on the baking sheet for 5 minutes, then transfer them to a wire rack to cool completely.
Serve and enjoy these festive Valentine cookies!
