There is some disagreement over when to celebrate Pie Day. Some (including the American Pie Council) cite January 23 as the day, the reason allegedly being that the digits of 1/23 are "easy as pie." Others (generally math nerds) say it must be March 14, or "Pi" Day.
Of course, this is a very silly argument, because really, it's an opportunity to enjoy pie on two separate occasions, whether baked at home or at a roadside stand, cafe, or bakery. But as a shout-out to the math nerds, here's a Pi-shaped Pie for March 14.
Use the template with your favorite pie crust and use whatever filling you'd like (I used peanut butter and chocolate chips), but know that it's best enjoyed at 1:59 PM...and 26 seconds.
