An easy, 5-ingredient Halloween dessert featuring chewy sugar cookie bars baked with a layer of creamy vanilla frosting and festive sprinkles.
Do not overbake the cookie base as it continues to cook from residual heat. Ensure bars are completely cool before cutting to prevent crumbling. For cleaner cuts, use a sharp knife and wipe the blade between slices.
