I need the Peanut M&M's peanut butter ASAP! There’s nothing that’s more classically American than peanut butter—except when you pair it with homemade jelly, of course! Whether you like it on bread, baked into a sheet cake or in peanut butter cookies, there’s no denying that PB makes everything better. If there’s one thing we love as much as peanut butter, it’s peanut M&M’s. The new M&M’s Mix Packs already pack all the best Peanut M&M flavors in one bag, and now our favorite candy brand has gone one step further.
