Healthy Recipe for National Pi Day

Healthy Recipe for National Pi Day

Happy National Pi Day to all those math lovers out there! The Greek letter Pi (“π”) is a mathematical symbol that represents the ratio of the circumference of a circle to its diameter. This ratio is approximately 3.14159265. . . It has been calculated to over one trillion digits beyond its decimal point! Many formulas in mathematics, science and engineering involve Pi, making it one of the most important mathematical constants. We celebrate this day, obviously, on March 14th (3/14) every year.

Pi in Your Face

So why should we get excited about a mathematical constant? Let me now introduce you to the English term “homophone”. A homophone is when two or more words have the same pronunciation but different meanings or spellings. I highly recommend that you celebrate National Pi Day by eating a slice (not 3.14 slices) of pie! Try this simple, delicious, and healthier apple pie recipe to celebrate National Pi Day without any of the guilt. After all, apples are just so fantastic!

Apple Pie Baked in the Apple

via Genius Kitchen /

Total Time: 1 hour 10 minutes

Serving Size: 1 apple


  • 1 pie crust
  • 6 Granny Smith apples
  • ¼ cup sugar
  • 1 Tbsp. brown sugar
  • ¼ tsp. cinnamon (more or less as desired)


  • Heat oven to 375°.
  • Cut off the top of 4 apples and discard. Remove the inside of each apple with a spoon very carefully, as to not puncture the peel.
  • Remove the skin from 2 additional apples and slice very thinly. These apple pieces will give you filling needed to fill the four apples you are baking.
  • Mix sliced apples with sugars and cinnamon in a bowl. If you prefer more or less cinnamon and sugar, make adjustments as desired.
  • Scoop sliced apples into hollow apples.
  • Roll out pie crust and slice in ¼ inch strips.
  • Cover the top of the apple in a lattice pattern with pie crust strips.
  • Place apples in an 8×8 pan. Add just enough water to cover the bottom of the pan. Cover with foil and bake for 20-25 minutes.
  • Remove foil and bake for an additional 20 minutes or until crust is golden brown and sliced apples are soft.
