These ultimate frosted sugar cookie bars are soft, buttery, and topped with a creamy vanilla frosting, perfect for parties and easy to make with pantry staples.
Use softened unsalted butter for best texture and flavor. Avoid overmixing the batter to keep bars tender. Chill dough slightly before baking for a more tender crumb. Frost only when bars are completely cooled to prevent melting. Use a warm knife for clean cuts.
