A soft and buttery sugar cookie baked in a cake pan, topped with a bright and creamy orange buttercream. Perfect for Halloween parties and easy enough for a weeknight treat.
Bring all ingredients to room temperature for best results. Press dough evenly into the pan. Do not overbake; the center should be slightly soft. Use fresh orange zest for the buttercream. Store at room temperature for up to 3 days; do not refrigerate.
