In celebration of Pi Day, why not make a yummy treat that incorporates another mathematical favorite - inverse numbers.1

Standard peanut butter cups combine a chocolate exterior with creamy peanut butter insides, and they're fantastic. Though it may be hard to believe, when swapped to produce a peanut buttery crust filled with creamy chocolate filling, they're even more delicious.

1Geek note: The multiplicative inverse of a number (x), also called the reciprocal, is defined as 1/x or x-1

Step 1: You'll Need. . .


For the Crust (amounts can be doubled if desired - this makes approximately 6 mini-pies or one 10 inch tart/pie):
  • 1/2 cup all-purpose flour
  • 1/2 teaspoon baking soda
  • pinch of salt (approximately 1/16 teaspoon)
  • 1/4 cup packed brown sugar
  • 2 tablespoons sugar
  • 4 tablespoons (or 1/4 cup or 1/2 stick) butter
  • 1/2 cup smooth peanut butter, at room temperature
  • 1/2 large egg (beat the egg, then measure out half of it)
  • 1/4 teaspoon pure vanilla extract
For the Filling (you may end up with some extra, but I for one don't mind extra chocolate pudding):
  • 1/8 cup cornstarch
  • 1/4 cup sugar
  • 1/16 teaspoon salt (a large pinch)
  • 1/4 cup milk (2% or whole)
  • 1 cup heavy cream
  • 3 ounces semisweet or dark chocolate, coarsely chopped
  • 1/2 teaspoon pure vanilla extract
Optional Garnish:


For the Crust:
  • large mixing bowl and wooden spoon or hand mixer (food processor can also be used)
  • measuring cups and spoons
  • small tart/pie pans (removable bottoms are strongly suggested) (this is the pan used here) - you can also make a larger pie if desired (crust should be enough for a 10 inch tart/pie pan - one with a removable bottom is suggested)
  • plastic wrap
  • dried beans or pie weights (optional)
  • shot glass or spoon to press dough into pan (optional but suggested)
For the Filling:
  • heavy-bottomed sauce pot
  • silicone spatula
  • whisk (optional - needed if your pudding gets lumpy)
  • fine mesh strainer (optional, also to prevent lumps)
  • measuring cups and spoons

looking at it makes me hungry
