This Is the Sweet & Salty Treat Your Pi Day Deserves

Today is National Potato Chip Day and Pi Day, which can only mean one thing: You need this chocolate peanut butter swirl tart recipe in your life. With a salty potato chip crust and a sweet, rich filling, this treat is both a flavor and holiday mash-up of epic proportions.

Pi Day celebrates the mathematical constant Pi, but food-lovers have capitalized on the holiday to dedicate an entire day to eating pie in all forms, whether it’s a pizza pie, a double-crust pie, a mini pie, or, in this case, a tart.

Because it’s a work week and you might not have time to make pie dough from scratch when you get home, consider this easy tart your ticket to Pi Day bliss. All you have to do is pulse a bag of kettle-cooked potato chips (this is not the time for any wacky flavors; a simple salted variety here is best) in your food processor until the chips are finely ground. Then add in some melted butter and a bit of all-purpose flour until everything is combined — and that’s your “dough.”

Press the potato chip crust into a tart pan, bake it for about 12 minutes, and then fill it with a glorious swirled mixture of smooth peanut butter and creamy chocolate ganache.

The hardest part is waiting for the filled tart to chill and set in the fridge. One hour will do the trick, but you can go up to eight hours. When you’re ready to eat, just cut it into wedges and dive in.
