It looks like IHOP and Krispy Kreme are duking it out for the best deal of the week: This Friday, with every purchase of a dozen donuts, Krispy Kreme will give you another dozen for just 78 cents. By our math, that's a lot of glazed goodness.

In 1937, Krispy Kreme released it's first batch of donuts in North Carolina to great success, and while their birthday is July 13, the chain will help kick-start the weekend by offering this deal on July 10. After years of financial hardship, it seemed unlikely that the beloved brand would make it to such an age, making their 78th anniversary all the more sweet and victorious.

Unfortunately the deal isn't as easy as stopping by a shop, dropping some change on the counter, and walking out with a piping hot dozen. Sign up for the offer on Facebook, check your email for a confirmation, and be on your way to a blissful, donut-induced sugar coma.

UPDATE: July 8 at 11 a.m.

Krispy Kreme is celebrating its birthday even earlier than this cheaper dozen, bringing back its special edition birthday cake and brownie batter donuts for a limited time. You'd be silly not to take advantage of the coinciding promos.

The birthday cake pastry is filled with both the company's namesake cream and cake batter filling, then topped with yellow icing and confetti sprinkles. The brownie batter donut is a triple chocolate treat filled with rich, fudgey brownie batter, then topped with milk chocolate icing and mini chocolate chips.
