In a bowl, whisk almond flour, AP flour, powdered sugar, baking powder, salt, and orange zest.
Add olive oil, egg, yolk, and vanilla. Mix until a soft dough forms.
Add chocolate chips and fold them in gently — do not knead.
Transfer dough to parchment and press into a tight rectangular block (about 2.5 x 5 inches).
Chill 1 hour (or freeze 20 minutes).
Slice into ¼‑inch rectangles.
Bake at 350°F (175°C) for 8–10 minutes, until edges are just barely golden.
Cool fully for clean edges and glossy chocolate.
