You all know I love science, but did you also know I am a math nerd? I loved calculus. I say it in the past tense because after years of not utilizing it I barely remember how to do it. It just came easily to me and was like art in math form.

These days, even in my day job as a research scientist I primarily use simpler math equations, but on special occasions I get to do more geometric ones. As such I had to make sure to celebrate Pi Day! A very special occasion indeed.

Irish Cream Pie with Pretzel Crust & Whiskey Caramel

Of course as I often do I chose to also draw inspiration from the upcoming St. Patrick’s Day holiday when choosing the flavor of todays pie – Irish Cream! Complete with a salty pretzel crust, fluffy white chocolate Irish cream filling, topped with whiskey caramel. Why not some more whipped cream and crushed pretzels to finish it off?

So how are you going to celebrate Pi Day? In case this pie isn’t speaking to you, I’ve linked up to several other bloggers’ recipes celebrating with other pie recipes. The list is right before the recipe!

In addition to all those delicious pies listed above, I would also like to point out that the only year I failed to post a recipe for Pi Day was 2020. Feel free to peruse all my previous creations dating back to 2011! Almost half of them are also St. Patrick’s Day themed which is no surprise since they are only 3 days apart. Two for one! There are also a couple savory options as well.

Slice of Irish Cream Pie with a pretzel crust and topped with whiskey caramel


Yield: 12 servings Prep Time: Cooking Time:
Nutrition facts: 200 calories 20 grams fat



6 oz. mini pretzels, crushed

4 Tbsp unsalted butter, melted


1/3 cup Irish cream liqueur

4 oz. white chocolate, chopped

1 (8 oz.) package cream cheese, room temperature

1/4 cup sugar

1 (12 oz.) container frozen whipped topping, thawed and divided


Whiskey caramel sauce

More mini pretzels


  1. Preheat oven to 350 degrees. Lightly grease a 9 inch pie pan with nonstick spray, set aside.
  2. In a small bowl, combine the pretzel crumbs and butter. Stir together to moisten the crumbs, then pour into the pie pan. Press firmly onto bottom and up the side of the pie pan, using the flat bottom of a glass to ensure that the crust is even. Bake for 8-10 minutes, or until slightly golden. Allow to cool completely
  3. Meanwhile, make the filling. In a small microwave safe bowl, heat the Irish cream in the microwave on high power for 30-seconds. Repeat for 15-second intervals until the Irish cream is steaming, but not boiling. Add the chopped white chocolate to the hot Irish cream and set aside, stirring occasionally, until all chocolate is melted and the mixture is cooled.
  4. In a large bowl, beat together the cooled Irish cream, cream cheese and sugar with an electric mixer on medium speed until well combined. Gently mix in 2 cups whipped topping until thoroughly combined. Spoon mixture into cooled pie shell. Using a spatula, smooth mixture to edges of pie. Chill in fridge at least 4 hours or overnight.
  5. Serve slices with leftover whipped topping, caramel drizzle, and more crushed pretzels.
