1️⃣ Prep:
Preheat your oven to 350 °F (175 °C). Line baking sheets with parchment paper or silicone mats.

2️⃣ Combine dry ingredients:
In a bowl, whisk together flour, baking powder, baking soda, and salt. Set aside.

3️⃣ Cream butter & sugar:
In a separate bowl, beat softened butter and sugar until light and fluffy, about 2–3 minutes.

4️⃣ Add egg & flavorings:
Mix in the egg until combined, then stir in orange zest and vanilla extract.

5️⃣ Blend in sour cream & flour:
Alternate adding the dry mixture and sour cream (or yogurt), beginning and ending with dry ingredients. Mix just until combined—don’t overmix.

6️⃣ Shape the cookies:
Scoop dough into 1 ½–inch balls and place them 2 inches apart on the baking sheets. Flatten slightly with your fingers or the bottom of a glass.

7️⃣ Bake:
Bake for 10–12 minutes until the edges are lightly golden. Let cookies cool on the baking sheet for 5 minutes, then transfer to wire racks to cool completely.

8️⃣ Make the glaze:
In a small bowl, whisk together powdered sugar, orange juice, orange zest, and vanilla until smooth and pourable. Adjust consistency—add a tiny bit more juice to thin, or powdered sugar to thicken.

9️⃣ Glaze the cookies:
Once cooled, drizzle or spread the glaze over each cookie. Immediately sprinkle with extra zest, coarse sugar, or mini white chocolate chips, if desired.

10️⃣ Let set & serve:
Allow the glaze to set (~10 minutes). Store cookies in an airtight container at room temperature for up to 4 days, or freeze extras.
