The Medium Bar Pan is perfect for brownie and bar cookie mixes. It can also roast your vegetables or reheat last night’s leftovers. The unglazed cooking surface won’t retain oils, odors or flavors. Nonstick “seasoning” builds up with every use: the darker it looks, the better it cooks! It is microwave, freezer, conventional and convection oven-safe. Measures approximently: 11½" x 7¾" x ¾".
