Preheat your oven to 350°F (175°C).

Line a baking sheet with parchment paper.

In a mixing bowl, whisk together the flour, baking soda, and salt.

In another bowl, beat the softened butter and granulated sugar until light and fluffy.

Add the egg, vanilla extract, milk, and food coloring to the butter mixture and mix until fully combined.

Gradually add the dry ingredients to the wet mixture, mixing until just combined.

Using a cookie scoop or tablespoon, drop dough onto the prepared baking sheet, spacing them about 2 inches apart.

Bake for 10-12 minutes or until the edges are lightly golden.
