Kellogg's may be saying good-bye to Famous Amos and Keebler cookies.

According to the cereal maker, it is exploring a sale of its cookie and fruit snack businesses so it can focus on "core" parts of the company.

Others possibly up for sale include Mother's and Murray cookies, as well as Little Brownie Bakers. Kellogg's Fruity Snacks and Stretch Island fruit snacks are also on the list.

The company will share more details during an investor's event later today.
