1. Preheat the oven to 350°F and line a baking sheet with parchment paper.

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

3. In a large bowl, beat the softened butter, brown sugar, and granulated sugar until light and creamy.

4. Add the egg, maple syrup, and vanilla extract, then mix until smooth.

5. Gradually add the dry ingredients to the wet ingredients and mix just until a soft dough forms.

6. Scoop the dough into evenly sized portions and place them on the prepared baking sheet, leaving space between each cookie.

7. Bake for 9 to 11 minutes, until the edges are set and the centers are still soft.

8. Let the cookies cool on the baking sheet for 5 minutes, then transfer them to a wire rack to cool completely.

9. Melt the white chocolate in a microwave-safe bowl in short intervals, stirring until smooth.

10. Dip half of each cooled cookie into the melted white chocolate.

11. Place the dipped cookies on parchment paper and sprinkle with flaky sea salt if using.

12. Let the chocolate set completely before serving or storing.
