Calling all mathematicians and cookie lovers– these pi cookies are ready celebrate Pi Day on March 14th! There may not be a better way to wish someone a Happy Pi Day than theses cookies shaped like the Greek letter, Pi.
What is Pi Day?
Pi Day is a day dedicated to celebrate math. Specifically, the ratio Pi with a value of 3.14.
Pi Day Cookies give you a reason to celebrate Pi Day 2021. Not sure what Pi Day is but love to eat cookies? Read on! It is a day for mathematicians to get excited since March 14th can be written as 3/14. It’s also fair game for anyone who likes pies…or cookies in this case!
The Greek letter, Pi, is used to represent the ratio of a circle’s circumference (measurement around the circle) to its diameter (measurement across the circle)– and it is always 3.14. Want to learn more– check out www.piday.org.
I originally shared these pi cookies in the year of 2015 which was especially noteworthy since the next digits of Pi are also noted in that date: 3.1415 so 3/14/15. If you really wanted to get particular you could send up a cheer at 9:26 and 53 seconds since the first ten digits of Pi are 3.141592653 .
The cookies are just as good for this year’s national pi day. Who needs pie when you can have cookies?
My son’s math class had a Pi day celebration with pies and I sent in these cookies to add to the fun.
I also sent a few of these decorated sugar cookies to my friend who had recently earned tenure in her position as a math professor. (Yeah, so very happy for you!)
Math brains appreciate quirky occasions like Pi Day and everyone appreciates cookies so this is a win-win situation!
Pi Cookie Cutter:
So…it’s not likely that you have a Pi cookie cutter in your collection. I don’t either, although I may by this time next year. Math cookie cutters aren’t an every day item.
Update: I do have a Pi Cookie Cutter now. I received it as a gift– hooray! Here are two options from Amazon: this comfort grip pi cookie cutter or this copper pi cookie cutter.

Pi Cookie Template
You can easily make a template to create your own Pi shape cookie. Start with a square or rectangle cookie cutter. This helps you have consistency in shape and size, as well as a straight edge on top.
Use cardstock or cardboard to cut a shape of Pi that fits within your cookie cutter square. Then when you roll out your dough, cut it into squares first with the cookie cutter and use a sharp knife to cut away the small bit of extra dough around your Pi shape.
Remember that these are simply cookies and will be eaten in three or four quick bites– do not be hard on yourself as you try to create the world’s most perfect Pi shape. They are just cookies! Leave them plain or ice them with royal icing or a simple glaze of confectioners sugar mixed with milk.
Print a Pi Symbol Label!
Did you know that I have a FREE Printables library? I love sharing labels that you can download and print yourself.
This printable sheet of 12 labels offers the Greek letter Pi which would be fun for math class, note cards, and Pi Day celebrations.

If you need a standard cut-out cookie recipe I often turn to Bridget Edward’s recipe found on her site Bake at 350. She has excellent step by step directions and if you prefer a cookbook in your kitchen rather than a website, her cookie cookbooks are a necessity for any cookie baker.

Pi Day is celebrated each year on March 14th.
Pi is a mathematical constant that represents a ratio in a circle. The symbol, pi, is the ratio of the circumference (distance around the circle) to the diameter (distance across the circle). The value is rounded to 3.14 but is actually an irrational number that goes on with no ending digit. 3.141592654…
Anyone can celebrate! Math classes, schools, libraries, math clubs, scientists, engineers, and beloved math nerds often mark March 14th on the calendar but everyone is welcome to have some math fun! Hopefully Pi Day will make a math lover out of anyone!
Eating pie is a popular activity to mark P Day. I would suggest that eating these Pi Cookies is just delicious! Some people host math events, museums have special displays, and schools might offer fun math games for everyone to enjoy.
A local family in my neighborhood hosts a 3.14 mile run on March 14th. Possibilities are endless in ways to recognize Pi Day!
There is even a popular song with many renditions on You Tube called the Pi Day song which helps in memorizing the first 100 digits of pi.
Pies such as cherry pie, apple pie, lemon meringue pie, blueberry pie, chocolate pie, cookies, pizza pie, shepherd’s pie, pot pie.

Love these cookies! I did make pies, but they didn't come out quite as planned, so I kind of never even took a picture! They tasted good though! I'll bet these cookies were a hit and those photos are spectacular!
