Course Dessert, Special Treat


Graham Crust:

  • 2 c. graham cracker crumbs
  • 3 Tbsp. sugar
  • 1/4 tsp. salt (omit salt if using salted butter)
  • 1 stick (4 oz.) unsalted butter, melted

Peanut Butter Layer:

  • 8 oz cream cheese
  • 1 1/2 tsp. vanilla
  • 3/4 c. peanut butter
  • 1 c. powdered sugar
  • 1 c. heavy cream
  • 5 Tbsp. instant white chocolate pudding mix

Chocolate Mousse Layer:

  • 5.5 oz. semi-sweet chocolate chips (I used Ghirardelli, about a heaping 3/4 cup)
  • 2 c. heavy cream
  • 1 tsp. vanilla
  • 3 Tbsp. instant white chocolate pudding mix


For the crust:

  • Combine graham crumbs, sugar, salt, and melted butter. Lightly spray a standard size 9 1/2 inch pie plate with nonstick spray. Press crust evenly into pan, building up an edge around the sides. Bake in preheated 350 degree oven for about 10 minutes. Cool completely.

For Peanut Butter Layer:

  • Ina mixing bowl, beat together 1 8oz. block of cream cheese with vanilla. Mix in peanut butter. Add powdered sugar and mix together well. Add heavy cream. Beat until mixture thickens slightly, about 1 to 2 minutes. Scrape sides of bowl. Add 5 Tbsp. pudding mix, Beat 2 minutes.
  • Spread half of peanut butter mixture into crust. Chill remaining half for piping around the edge of the pie later. Cover and chill.

Chocolate Mousse Layer:

  • In a mixing bowl, add 5.5 oz. semi-sweet chocolate chips, about a heaping 3/4 cup. (I used Ghirardelli) Bring 1 cup of the heavy cream to a simmer and pour over chips. Add 1 tsp. vanilla. Rest 1 minute. Mix together well, until all chips are melted. Stir in remaining cup of cold heavy cream. Whisk together well. Cover and chill 2 hours.
  • Beat until mixture begins to thicken. Add remaining 3 Tbsp. of instant white chocolate pudding mix. Beat for 2 minutes. Mixture will become thick and fluffy. Spread chocolate mousse evenly on top of peanut butter layer.
  • With remaining chilled peanut butter cream, pipe a border around the edge of the pie using a star tip and piping bag. (See links for items used in this recipe.)
  • Best chilled overnight, or for at least a few hours. Enjoy!

    I made this for my husband’s birthday last year and he liked it so much I just made it for him again this year. He was licking the bowls clean tonight.

    PS: if you happen to have any leftovers slice it up and freeze it- it thaws beautifully

    1. Thanks, Samantha! So glad to hear that. Keeping one of these in the freezer is a good idea for pie any time. I’m happy to hear it’s turned into a birthday favorite! Thanks for the nice comment.
