A tender and buttery sugar cookie cake topped with smooth, elegant royal icing, perfect for celebrations like graduations and parties.
If edges brown too quickly, tent with foil halfway through baking. Let icing dry fully for clean slices and lasting decoration. Use softened butter for best texture. Sift powdered sugar to avoid lumps. Beat royal icing until stiff peaks form but still spreadable. Practice piping on parchment paper before decorating the cake. Store leftovers in airtight container at room temperature up to 3 days or refrigerate up to a week.
