A PI a Day (keeps us happy)…

Who here celebrates PI Day? I will raise my hand (and my families hands, lol)! Every year we celebrate, and every year we try to make different pies. This year we made 3: Apple, chocolate cream, and key lime. They were all delicious, but the key lime hit different, so that one is the recipe I am posting. Plus, it is super easy to make… an added bonus!


Graham cracker crust

  • 1 1/2 cups graham cracker crumbs
  • 1/3 cup granulated sugar
  • 6 tbsp. butter, melted

Key Lime Filling

  • 28 oz. sweetened condensed milk
  • 1/2 cup light sour cream
  • 3/4 cup key lime juice
  • zest from 2 limes

Whipped Cream Topping

  • 1 cup heavy whipping cream
  • 1/2 cup powdered sugar
  • 1 tsp vanilla extract


Graham Cracker Crust

  • Preheat oven to 375 degrees.
  • Mix graham cracker crumbs, sugar, and butter in a small bowl. Press the crumb mixture into an 9″ pie pan. Bake for 7 minutes. Cool for about 30 minutes.

Key Lime Filling

  • Preheat oven to 350 degrees.
  • Whisk together sweetened condensed milk, sour cream, lime juice, and lime zest in a medium bowl. Pour into prepared graham cracker crust and bake for 10 minutes.
  • Let pie cool slightly before chilling. Chill for about 3 hours.

Whipped Cream Topping

  • Beat heavy cream and sugar together in a mixer until stiff peaks form. Beat in vanilla. Pipe the whipped cream on top of the (chilled) pie. Top with additional lime zest if you would like!

Do you celebrate PI Day? What are your favorite types of pie? Is there a pie that you make that people may not be familiar with? Let me know in the comments! I would love to hear from you!
