Preheat your oven to 375°F (190°C) and line two baking sheets with parchment paper.

In a medium bowl, whisk together flour, baking powder, and a pinch of salt.

In a large mixing bowl, beat softened butter and granulated sugar together until light and fluffy.

Add the room temperature egg to the butter and sugar mix until incorporated.

Gradually mix in the dry ingredients and fresh orange juice until just combined.

Scoop and roll the dough into balls and place them on the prepared baking sheets.

Bake for 10-12 minutes until the centers are set and lightly golden.

Let the cookies cool on the sheets for about 5 minutes, then transfer to a wire rack.

In a small bowl, whisk together confectioners' sugar, orange zest, orange juice, and melted butter for the glaze.

Spread the glaze over cooled cookies and let set for at least 15 minutes before serving.
