  • 2 cups Oreo cookie crumbs
  • 2 tablespoons sugar
  • 1/3 cup butter, melted
  • 1-1/2 cups sugar
  • 1/3 cup cornstarch
  • 2 tablespoons all-purpose flour
  • 1/2 teaspoon salt
  • 6 cups 2% milk

  • 1 cup creamy peanut butter
  • 2 cups heavy whipping cream

Reduce heat; cook and stir 2 minutes. Remove from heat. Stir a small amount of hot mixture into egg yolks; return all to pan, stirring constantly. Bring to a gentle boil; cook and stir 2 minutes.
  • 3. Remove from heat. Stir in peanut butter until smooth. Pour over crust. Cool to room temperature. Refrigerate, covered, at least 2 hours.

    This recipe looks amazing! I've noticed in the reviews that some people seem to be having trouble with the sauce thickening. I've had this trouble in the past with other custard recipes that call for cornstarch so I usually substitute for AP flour and have no problems.

    The peanut butter custard portion took a full hour from start to finish (most of that was stirring time!) and I'm not sure the results were worth quite that much effort. I ended up added more cornstarch after 45 minutes of stirring and then it thickened quickly. The custard was really yummy, but I preferred it warm.

    I've adapted the pie a little and it's so delicious! In the original size I use 5c milk and 2c of peanut butter, instead of 6c and 1c respectively. It turns out really good, but still too soft for my taste. I just made another few tweaks to it yesterday - I halved everything (3c milk, 3 yolks, etc) but used only 1/2c sugar, a full 1/3c starch, and a full cup of peanut butter in order to make a 9" pie. I probably used about half of that batch to fill my pie crust, so I'll have to do some tweaking. I let the milk mix cook for a pretty long time before adding my eggs, so after it set I had a more solid custard layer. It was silky and smooth, and the sweetness was just right! Super easy recipe with room for some playing around with it. Wholly recommend it!

    This is really good. You do have to make the custard from scratch, so be prepared to stand at the stove awhile. The only part we didn't like was the peanuts on top. They get soft. Maybe honey roasted would be better, or something that stays crunchy.

    This was excellent! For anyone who can't get the custard to thicken, just keep cooking and stirring, and stirring, and stirring. It will get thick.

    Yes step210 by all means, add 1tsp.of vanilla extract or even almond extract, and add a few Tbls of confectionery sugar, taste it before you beat it and adjust it to your liking. I hope this helps. :)

    I will be trying this soon! I have a question before I make it tho...everytime I make homemade whip cream, it tends to be a bit bland. Do most people add a flavoring like vanilla?
