Chocolate Peanut Butter Mousse Pie

Not the best photo, but we weren't worried about photos at the time!

Sometimes you just have to improvise. I mean, not all rental houses are stocked as fully as we might hope them to be.

But, when you are celebrating a very important person's impending nuptials with a bachelorette party to end all bachelorette parties--in Lake Tahoe no less--there must be chocolate peanut butter pie.

And so I crushed the graham crackers for the crust in a Ziplock bag with a melon (success!), because there was no food processor. And Amber "whipped" the cream for the mousse in the blender (mostly a success!), because there was not an electric beater. Having no tablespoon measuring spoon, we dutifully counted out 3 teaspoons for each one. The fact that there was no also pie pan was also a bit of a set back. Luckily, there was a Kmart down the way, so I bought one. (When is the last time you were in a Kmart? Weird!) Pie pan doesn't fit in the freezer? Refrigerator will have to do. Sometimes you just have to be flexible.

This pie is really rich (you probably got that impression from the name), but it is super easy and very delicious--if you like peanut butter and chocolate. (If you don't like peanut butter and chocolate, you should really, really work on that.) This is a chilled pie, so it's great for summer parties. Make it ahead, then just sit back and enjoy the feather boas---er, festivities.

Chocolate Peanut Butter Mousse Pie
  • Non-stick vegetable oil spray
  • 7 whole graham crackers, coarsely broken
  • 1/4 cup (1/2 stick), unsalted butter, melted
  • 4 tablespoons sugar, divided
  • 1 1/3 cups bittersweet or semi-sweet chocolate chips (about 8 ounces)
  • 2/3 plus 1 3/4 cups chilled whipping cream, divided
  • 2 tablespoons light corn syrup
  • 2 teaspoons vanilla extract, divided
  • 6 ounces (1 cup) peanut butter chips
  • 2 tablespoons creamy peanut butter (like Skippy, not old-fashioned or freshly ground)
  1. Preheat oven to 350 degrees. Spray a 9-inch glass pie pan with non-stick spray. Blend graham crackers, melted butter and 2 tablespoons of sugar in a food processor until moist clumps form. Press crumb mixture over bottom and up sides of prepared pie dish. Bake crust until lightly browned, around 15 minutes.
  2. Meanwhile, combine chocolate chips, 2/3 cup whipping cream, corn syrup and 1 teaspoon vanilla in a microwave-safe bowl. Microwave on medium heat until chocolate softens, about 3 minutes, checking it frequently. Whisk until melted and smooth. Spread chocolate mixture over the bottom of the crust. Freeze 10 minutes.
  3. Microwave peanut butter chips and 3/4 cup cream in a large microwave-safe bowl on medium heat at 15 second intervals, stirring often, until chips soften. Whisk in peanut butter and 1 teaspoon of vanilla. Set aside and cool to barely lukewarm. In another medium bowl, beat remaining 1 cup cream and and 2 tablespoons sugar in a medium bowl until very thick, but not yet holding peaks. Fold in peanut butter mixture in 3 additions. Spoon mousse evenly over chocolate layer. Chill at least 1 hour and up to 1 day.


  1. This pie was next level delicious, I wish I could eat it every day! Thanks for making it, Alexis!!!!

  2. Every time I make this pie, I shed a tear as I eat the last bit. It is soooo delicious, more than it should be allowed, since it is so simple to make.

  3. OK here are some notes on alterations: I would use a whole 'brick' of graham crackers (9 or 10 crackers) and add more butter. I like a thicker crust. Also for the peanut butter mousse I would use less cream with the chips - since I only buy the small cream, and it's not quite enough to get a full cup of cream at the end. Or just measure out the cup of cream first and put the rest in with the peanut butter chips.
