Preheat the oven to 350°F (175°C).

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

In another bowl, cream together the clotted cream and sugar until light and fluffy.

Beat in the egg and vanilla extract until well combined.

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

Using a cookie scoop, drop dough onto a baking sheet lined with parchment paper.

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

Allow cookies to cool on the baking sheet for a few minutes before transferring to a wire rack to cool completely.
