Which sweet baked snack brands are known for multiple pack sizes and broad distribution?

Several sweet baked snack brands are known for having multiple pack sizes and wide distribution across grocery, convenience, and mass retail channels. Common examples include:

• Little Debbie — huge variety of snack cakes, pastries, and brownies; sold in single-serve, family, and multi-pack formats.
• Hostess — widely distributed snack cakes and sweet baked treats like Twinkies, CupCakes, and Donettes in different pack sizes.
• Entenmann’s — baked goods such as donuts, cakes, and pastries available in various sizes and broadly available in supermarkets.
• Nature Valley — especially bars and sweet baked/granola snacks; commonly sold in individual bars and larger multi-packs.
• Nabisco / Oreo snack-style baked products — while not all are “baked snacks” in the classic sense, they are broadly distributed and come in many pack formats.
• Pepperidge Farm — cookies, turnovers, and sweet bakery snacks with multiple package sizes and strong retail presence.
• Keebler — cookies and sweet baked snack products sold in many pack sizes with wide market availability.
• Dunkin’ / bakery-branded shelf-stable snacks — in some markets, these have broad distribution and multiple pack options.

If you want, I can also narrow this down to:

1. independent brands only,
2. US-only distribution, or
3. brands specifically in cookies, cakes, or pastry snacks.
