Prepare the Dough:

• In a medium bowl, whisk together flour, baking powder, and salt.
• In a large mixing bowl, cream butter and sugar until light and fluffy. Add the egg, orange zest, orange juice, and vanilla extract. Mix until combined.
• Gradually add the dry ingredients to the wet mixture, stirring until a soft dough forms.

Chill the Dough:

• Divide the dough into two portions, wrap them in plastic wrap, and chill in the refrigerator for at least 30 minutes (or up to 2 days).

Preheat the Oven:

• Preheat your oven to 350°F (175°C). Line baking sheets with parchment paper.

Shape the Cookies:

• On a lightly floured surface, roll out the dough to 1/4-inch thickness. Use fish-shaped cookie cutters to cut out cookies. Re-roll the scraps and cut additional shapes.

Bake the Cookies:

• Place the cookies on the prepared baking sheets, leaving about 1 inch of space between them.
• Bake for 10–12 minutes, or until the edges are lightly golden.
• Allow the cookies to cool on the baking sheets for 2 minutes, then transfer them to a wire rack to cool completely.

Decorate (Optional):

• Once cooled, decorate the cookies with royal icing, sprinkles, or edible glitter for a fun, ocean-inspired look.
