Whisk together flour and sugar in a large mixing bowl until combined.

Melt the butter in a microwave-safe bowl, stirring every 30 seconds until liquefied.

Combine the melted butter with the flour-sugar mixture, then add orange juice and zest.

Mix until smooth and homogenous.

Chill the batter in the fridge for at least 2 hours.

Preheat the oven to 350°F (175°C).

Pipe the batter onto lined baking sheets leaving space between cookies.

Bake for about 10 minutes or until edges are golden.

Optionally, shape cookies over a rolling pin while warm.

Store cookies in an airtight container once cooled.
