Preheat your oven to 350°F (175°C) and prepare baking sheets lined with parchment paper.

In a large mixing bowl, cream together softened butter and granulated sugar until light and fluffy, about 2-3 minutes.

Add the egg and vanilla extract to the mixture and mix until fully incorporated.

In a separate bowl, whisk together the flour, baking soda, and salt. Gradually incorporate this into the wet ingredients until just combined.

Fold in the chopped maraschino cherries gently into the dough.

Drop rounded tablespoons of dough onto prepared baking sheets, leaving space between them.

Bake for 10-12 minutes, until the edges are golden and the centers remain soft.

Let cookies cool on the baking sheet for 5 minutes before transferring to a wire rack.
