Step 1: Prepare the Dough

1. In a medium bowl, whisk together the flour, baking powder, baking soda, and salt. Set aside.

2. In a large mixing bowl, cream the softened butter and sugar until light and fluffy (about 2–3 minutes).

3. Beat in the egg, vanilla extract, orange juice, and orange zest until well combined.

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

Step 2: Chill and Bake

1. Cover the dough and refrigerate for at least 30 minutes. This prevents the cookies from spreading too much during baking.

2. Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper.

3. Scoop rounded tablespoons of dough and roll them into balls. Place them about 2 inches apart on the baking sheet.

4. Flatten each ball slightly with the back of a spoon.

5. Bake for 10–12 minutes or until the edges are lightly golden. Cool completely on a wire rack.

Step 3: Make the Frosting

1. In a medium bowl, beat together the powdered sugar, softened butter, orange juice, orange zest, and vanilla extract until smooth and creamy.

2. Adjust the consistency as needed. Add more orange juice for a thinner frosting or more powdered sugar for a thicker one.

3. For a fun twist, add a drop of orange food coloring to enhance the frosting’s color.

Step 4: Assemble the Cookies

1. Once the cookies are fully cooled, spread a generous layer of frosting on each one using a spatula or piping bag.

2. Garnish with additional orange zest, sprinkles, or a drizzle of melted chocolate for a decorative touch.
