To bake something is to cook it in a hot oven. When you bake a batch of blueberry muffins, your whole house smells delicious.

Whether you bake some cookies for dessert, a casserole to take to a potluck supper, or bake a clay pot in a kiln, you cook with a relatively slow, dry heat. You can also use the word bake figuratively: "Are you going to move into the shade, or are you just going to bake in the sun all day?" The Old English word was bacan, from a Germanic root.
