One thing I love about celebrating Pi(e) Day is that it always inspires me to think outside the pie plate, as it were. Something about this day gets my creative juices flowing. This year, I have been inspired to bring you not one but two fabulous pies! Last week I shared cinnamon bun pie (totally still drooling over that, by the way). After that I was feeling something more on the fruity side of the pie spectrum, but not your typical traditional pie crust + standard fruit filling. After extensive thought partly inspired by my recent stockpiling of passion fruit puree from the Latin grocery store, the idea of a passion fruit mousse pie just stuck with me.

Passion fruit is such an irresistible flavor to me. The sweet tartness of it and its intense fragrance is unlike anything else, but it can also be easily overpowered by other more dominant flavors. Ultimately I kept the flavors here simple to let the passion fruit shine. The chocolate crumb crust and dark chocolate ganache layer on the bottom serve to complement the silky smooth passion fruit filling. The fresh passion fruit seeds for garnish aren’t absolutely essential but if you can find fresh passion fruit, I really recommend using them. They add a nice brightness that is the perfect finishing touch to this deliciously unique pie.

PS – Shout out as always to my incredible high school calculus teacher Mr. Strawn! He rocked pi like nobody’s business. This one is for you!


For the filling: 

  • 100 grams (½ cup) passion fruit puree
  • 65 grams (1/3 cup) granulated sugar
  • 2 large eggs
  • 1 tbsp. water
  • 1 tsp. powdered gelatin
  • 170 grams (12 tbsp.) butter, very cold
  • 2 grams (½ tsp.) kosher salt
  • ½ cup heavy cream
  • 2 tbsp. confectioners’ sugar

For the crust: 

  • 79 grams (½ cup) flour
  • 3 grams (¾ tsp.) cornstarch
  • 75 grams (6 tbsp.) granulated sugar
  • 49 grams (½ cup) cocoa powder
  • 3 grams (¾ tsp.) kosher salt
  • 64 grams (4½ tbsp.) plus 21 grams (1½ tbsp.) butter, melted (divided)
  • 57 grams (¼ cup) finely chopped bittersweet chocolate
  • 57 grams (¼ cup) heavy cream

To finish: 

  • Whipped cream
  • Fresh passion fruit pulp

    To make the passion fruit curd, put the passion fruit puree in a blender with the sugar and blend until the sugar granules have dissolved. Add the eggs and blend on low until the mixture is bright orange-yellow. Transfer the contents of the blender to a medium pot or saucepan, and clean out the blender canister. Place the water in a small bowl and sprinkle the gelatin evenly over the top to bloom the gelatin. In the saucepan, heat the passion fruit mixture over low heat, whisking often. It will begin to thicken as it heats up. Once it boils, remove it from the heat and transfer to the clean blender canister. Add in the bloomed gelatin, butter, and salt, and blend until the mixture is thick, shiny and very smooth. Transfer to a heatproof container, cover and refrigerate until completely cool, at least 1 hour.

    To make the chocolate crumb, heat the oven to 300˚ F. Line a baking sheet with a silicone baking mat or parchment paper. In the bowl of an electric mixer, combine the flour, cornstarch, sugar, cocoa powder, and salt. Mix on low speed until combined. Add in the 64 grams of butter and mix until the mixture starts to form small clusters. Spread the clusters on the prepared baking sheet. Baking for 20 minutes, breaking them up occasionally. Remove from the oven. The crumbs will dry and harden as they cool. Cool completely.

    Place the chocolate crumb mixture in the bowl of a food processor. Process until finely ground into a sand-like texture. In a bowl, combine with the remaining 21 grams of butter and mix with a fork until crumbly. Line the bottom of an 8-inch springform pan with parchment paper. Transfer the chocolate crumb mixture to the prepared pan and press firmly to the bottom and sides to form a thin crust. Place the chopped chocolate in a  small bowl. Heat the cream to nearly boiling. Remove from the heat and pour over the chocolate. Let stand 2 minutes, then whisk until a smooth ganache forms. Pour the ganache into the bottom of the chocolate crumb crust in the springform pan. Spread in an even layer. Transfer to the refrigerator or freezer briefly to set.

    With an electric mixer or immersion blender with whisk attachment, whip the heavy cream and confectioners’ sugar on high speed until stiff peaks form (be careful not to overbeat.) Remove the passion fruit curd from the refrigerator. Mix well with a spatula until smooth and silky. Gently fold in the freshly whipped cream in two portions until no streaks remain. Pour the passion fruit filling into the chocolate crust and smooth into an even layer. Cover and chill until set, at least 2 hours. When ready to serve, garnish with additional whipped cream and fresh passion fruit pulp as desired.

    I love the flavor of passion fruit and this pie looks so good. Is the puree frozen and you defrost before using? I’ve never seen it in the store before.

  • I love how creative you’ve been with passion fruit lately! It’s one of those flavors that I LOVE, but barely bake with. Need to stockpile some puree myself and get to baking this!

  • Tara McLaren

    I like passion fruit, sort of, when it’s juiced, mixed into yogurt or in any other food where the delicate taste is there, but you don’t have to see it. Scooping out the gross weird colored pulp that looks like eyes, or eggs or anything that comes from some sort of alien horror flick, just turns me off. Some foods should just be hidden, but not seen. Seriously though, I can’t be the only person who feels this way?

  • Tara

    this looks so yummy. I love passion fruit. I think the mousse will be great on a chocolate crumb base like a “no bake cheese cake”? Either way I’m soooo going to make this.

  • Annie

    Yes, it is usually found in Latin grocery stores (or you can order it frozen online, though shipping is very expensive.)

  • Annie

    I think it’s pretty!

  • The passion fruit looks fabulous, but I think I’m even more excited by a chocolate tart crust recipe that doesn’t call for Oreos! It feels so much fancier and gourmet (and probably healthier?) to make it from scratch!

  • Annie

    Right?! I was so excited about Pi Day and the passion fruit filling itself that I didn’t even have room to talk about this, but I am equally as excited about a non-Oreo based chocolate crust. Wooo!

  • Hi Annie, You have mentioned passion fruit puree. So how is it sold? Ist it as a can, or in the refrigerated section or frozen pulp? Once I saw passion fruit (I believe puree) in a packet in the frozen section of an Indian grocery. But it looked more liquidy without seeds. I love passion fruit as a child growing up there was a huge passion fruit bush in our high school (in my country) and we make juice and drink. So you can imagine how much I love passion fruit. I really want to make this pie.. Can you give me what kind of Latin stores? I have to search in my area…

  • Annie

    Yes, that frozen puree that looks pretty liquidy is what you want. You found it!

  • Thanks Annie
