Airtight containers are idea for storing baked goods and keeping them fresh. They keep moisture in and unwanted things out. And when I say unwanted things, I include nosy pets that can’t resist trying to taste your cake when your back is turned. Plastic wrap will keep moisture in your baked goods, too, but you can’t beat a good sturdy cake cover for resilience in the face of a hungry dog or cat.
The one pictured, incidentally, is a Wilton and it hasn’t let me down yet.
