That cup of coffee just not getting it done anymore? How about a Buzz Donut or a Buzzed Bagel? That's what Doctor Robert Bohannon, a Durham, North Carolina, molecular scientist, has come up with. Bohannon says he's developed a way to add caffeine to baked goods, without the bitter taste of caffeine. Each piece of pastry is the equivalent of about two cups of coffee. While the product is not on the market yet, Bohannon has approached some heavyweight companies, including Krispy Kreme, Dunkin' Donuts and Starbucks about carrying it.
