Create delicious-looking cookie treats for your family and friends with this wonderful bakery set! Put your cookies into the oven and close the door to see the light turn on. Set the timer then wait for the “ding!” Open the door and you will find your cookies have actually browned! A completely safe light actually turns the cookies a darker color. The color will return to normal after a short time. This set offers a realistic baking experience complete with timer, sound and light effects and color-changing cookies - great for getting kids excited about cooking!
