1. Prepare the Dough

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

In a large bowl, use an electric mixer to cream the softened butter and sugar until light and fluffy (about 2-3 minutes).

Add the egg, vanilla extract, orange zest, and orange juice to the butter mixture. Mix until combined.

Gradually add the dry ingredients to the wet ingredients, mixing until a soft dough forms.

2. Chill the Dough

Wrap the dough in plastic wrap and refrigerate for at least 1 hour to firm up.

3. Roll Out and Cut Shapes

Preheat the oven to 350°F (175°C) and line baking sheets with parchment paper.

On a floured surface, roll out the chilled dough to about ¼-inch thickness.

Use fish-shaped cookie cutters to cut out cookies. Arrange them on the prepared baking sheets.

4. Bake the Cookies

Bake in the preheated oven for 8-10 minutes, or until the edges are lightly golden. Cool the cookies completely on a wire rack before decorating.

5. Decorate (Optional)

Add a creative touch by using royal icing or melted white chocolate to pipe scales, eyes, or other designs on the cookies. Sprinkle with edible glitter or sprinkles for extra flair.
