Peanut Butter Mousse Pie: delicious, decadent and perfect with chocolate ganache

You guys. This Pie. This gorgeous Peanut Butter Mousse Pie has been on my mind since I made it.

Last year I made this Drunken Cherry Chocolate Torte, and the year before I made this Chocolate Hazelnut Mousse Pie. I have had this peanut butter version in my head for two years now. TWO years of dreaming about this very pie.

So for “pi day” (you know that math day on 3.14) I made this beautiful Peanut Butter Mousse Pie. I took these photos, ate my big slice (hey it’s part of the benefit package to my job, eating my work), and put the pie in our refrigerator in the garage.

Then we had a busy evening. Which turned into a busy week. And 7 days later I went to put something in the refrigerator and I saw this pie. This sad little pie that now had to be thrown away because it was forgotten.

This is one of the problems with being a dessert blogger. There are always desserts in the house. And if it’s not in the cake server on our counter, it gets forgotten.

Now, weeks later, this pie haunts me. Because it needs to be made again soon. And eaten with friends. With steaming cups of coffee. It needs to be known that it’s NOT a forgettable pie. It’s WORTH being enjoyed, delicious bite after delicious bite.

Yes. Sometimes I personify my food. And I assume it has feelings like a human. Which is why when I make a recipe fail (often!!) I feel bad for the ingredients. That somehow they didn’t get along well with each other. (is this weird??)

The ingredients in today’s Pie, they got along FABULOUSLY. I promise you. ENJOY!

Peanut Butter Mousse Pie

Yield: Serves 10-12

Prep Time: 4 hours

Cook Time: 10 minutes


For the crust:

  • 1 Pillsbury pie crust (single pie crust only)

For the mousse:

  • 1/2 cup cold water
  • 1 envelope unflavored gelatin
  • 1 cup creamy peanut butter
  • 1 pkg (8oz) cream cheese, softened
  • 3 cup heavy cream
  • 1 cup granulated sugar

For the ganache:

  • 1/2 cup dark chocolate
  • 1/4 cup heavy cream


  1. Unroll pie crust and press into the bottom of a 9inch springform pan. Poke with a fork and bake according to package directions (for single crust recipe). Set aside to cool.
  2. For the mousse, pour cold water into a small saucepan. Sprinkle with gelatin. Allow to bloom (absorb water) for two minutes. Heat saucepan on low and whisk gelatin water for several minutes until completely absorbed and dissolved. Remove from heat.
  3. In a large mixing bowl, beat cream cheese with peanut butter. Add gelatin mixture and beat for about 2 minutes. Set aside.
  4. In a clean and dry mixing bowl, beat heavy cream with sugar on high until soft peaks form (several minutes). Fold in peanut butter mixture and combine completely. Pour over cooled crust and refrigerate several hours (or overnight).
  5. To remove springform pan, use a plastic knife and run it along the edges. Release spring and life up. Pie should be set up nicely on the insert.
  6. For the ganache, combine the chocolate with the heavy cream in a microwave safe bowl.
  7. Heat for 30 seconds. Stir and heat an additional 30 seconds. Stir until smooth. Drizzle over pie. Serve immediately or return to refrigerator until ready to serve. Best eaten within 3 days. ENJOY.

    Should the pie crust go up the sides too or just the bottom? Can’t wait to try this!

    Would an Oreo cookie crumb base work too? This looks amazing!

    So sad! I just made this and it turned out lumpy. Mousse is all about texture, so I don’t think it’s salvageable :( What did I do wrong? I noticed the gelatin foaming while I beat it in the saucepan, did I cook it too long?

    • posted Jun 2, 2014 at 8:15 am

      Hmmm, it definitely shouldn’t be lumpy! The gelatin will thicken, but shouldn’t foam. Just get to the point of dissolved.

    Can I omit the gelatin or substitute it with something else?

    Oh gosh, this looks so incredible! I hardly ever bake or make with peanut butter because we have an allergy in the house, so that means I have to make two desserts, one peanutty, one not. I might have to just go ahead and make that sacrifice in the very, VERY near future for this one.

    Ganache- by dark chocolate, just like a candy bar or dark baking chocolate? Sorry, probably a dumb question.

    • posted May 19, 2015 at 8:43 am

      I either use Ghirardelli candy melts (they taste amazing), or Ghirardelli chocolate chips (dark)…or if I have any on hand, a good quality baking bar….
